Fluctuation-dissipation theorem

Fluctuation-dissipation theorem (Redirected from Fluctuation dissipation theorem) Jump to navigation Jump to search The fluctuation–dissipation theorem (FDT) or fluctuation–dissipation relation (FDR) is a powerful tool in statistical physics for predicting the behavior of systems that obey detailed balance. Given that a system obeys detailed balance, the theorem is a proof that thermodynamic fluctuations in a physical variable predict the response quantified by the admittance or impedance (to be intended in their general sense, not only in electromagnetic terms) of the same physical variable (like voltage, temperature difference, usw.), und umgekehrt. The fluctuation–dissipation theorem applies both to classical and quantum mechanical systems.

The fluctuation–dissipation theorem was proven by Herbert Callen and Theodore Welton in 1951[1] and expanded by Ryogo Kubo. There are antecedents to the general theorem, including Einstein's explanation of Brownian motion[2] during his annus mirabilis and Harry Nyquist's explanation in 1928 of Johnson noise in electrical resistors.[3] Inhalt 1 Qualitative overview and examples 2 Examples in detail 2.1 Brownsche Bewegung 2.2 Thermal noise in a resistor 3 General formulation 4 Ableitung 4.1 Classical version 4.2 Quantum version 5 Violations in glassy systems 6 Quantum version 7 Siehe auch 8 Anmerkungen 9 Verweise 10 Further reading Qualitative overview and examples The fluctuation–dissipation theorem says that when there is a process that dissipates energy, turning it into heat (z.B., friction), there is a reverse process related to thermal fluctuations. This is best understood by considering some examples: Drag and Brownian motion If an object is moving through a fluid, it experiences drag (air resistance or fluid resistance). Drag dissipates kinetic energy, turning it into heat. The corresponding fluctuation is Brownian motion. An object in a fluid does not sit still, but rather moves around with a small and rapidly-changing velocity, as molecules in the fluid bump into it. Brownian motion converts heat energy into kinetic energy—the reverse of drag. Resistance and Johnson noise If electric current is running through a wire loop with a resistor in it, the current will rapidly go to zero because of the resistance. Resistance dissipates electrical energy, turning it into heat (Joule heating). The corresponding fluctuation is Johnson noise. A wire loop with a resistor in it does not actually have zero current, it has a small and rapidly-fluctuating current caused by the thermal fluctuations of the electrons and atoms in the resistor. Johnson noise converts heat energy into electrical energy—the reverse of resistance. Light absorption and thermal radiation When light impinges on an object, some fraction of the light is absorbed, making the object hotter. Auf diese Weise, light absorption turns light energy into heat. The corresponding fluctuation is thermal radiation (z.B., the glow of a "red hot" object). Thermal radiation turns heat energy into light energy—the reverse of light absorption. In der Tat, Kirchhoff's law of thermal radiation confirms that the more effectively an object absorbs light, the more thermal radiation it emits. Examples in detail The fluctuation–dissipation theorem is a general result of statistical thermodynamics that quantifies the relation between the fluctuations in a system that obeys detailed balance and the response of the system to applied perturbations.

Brownian motion For example, Albert Einstein noted in his 1905 paper on Brownian motion that the same random forces that cause the erratic motion of a particle in Brownian motion would also cause drag if the particle were pulled through the fluid. Mit anderen Worten, the fluctuation of the particle at rest has the same origin as the dissipative frictional force one must do work against, if one tries to perturb the system in a particular direction.

From this observation Einstein was able to use statistical mechanics to derive the Einstein–Smoluchowski relation {displaystyle D={in ,k_{rm {B}}T}} which connects the diffusion constant D and the particle mobility μ, the ratio of the particle's terminal drift velocity to an applied force. kB is the Boltzmann constant, and T is the absolute temperature.

Thermal noise in a resistor In 1928, Johannes B. Johnson discovered and Harry Nyquist explained Johnson–Nyquist noise. With no applied current, the mean-square voltage depends on the resistance {Anzeigestil R} , {Anzeigestil k_{rm {B}}T} , and the bandwidth {displaystyle Delta nu } over which the voltage is measured:[4] {displaystyle langle V^{2}rangle approx 4Rk_{rm {B}}T,Delta nu .} A simple circuit for illustrating Johnson–Nyquist thermal noise in a resistor.

This observation can be understood through the lens of the fluctuation-dissipation theorem. Nehmen, zum Beispiel, a simple circuit consisting of a resistor with a resistance {Anzeigestil R} and a capacitor with a small capacitance {Anzeigestil C} . Kirchhoff's law yields {displaystyle V=-R{frac {dQ}{dt}}+{frac {Q}{C}}} and so the response function for this circuit is {Displaystil Chi (Omega )Äquiv {frac {Q(Omega )}{v(Omega )}}={frac {1}{{frac {1}{C}}-iomega R}}} In the low-frequency limit {displaystyle omega ll (RC)^{-1}} , its imaginary part is simply {Anzeigestil {Text{Ich bin}}links[chi (Omega )Rechts]approx omega RC^{2}} which then can be linked to the power spectral density function {Anzeigestil S_{v}(Omega )} of the voltage via the fluctuation-dissipation theorem {Anzeigestil S_{v}(Omega )={frac {S_{Q}(Omega )}{C^{2}}}ca {frac {2k_{rm {B}}T}{C^{2}Omega }}{Text{Ich bin}}links[chi (Omega )Rechts]=2Rk_{rm {B}}T} The Johnson–Nyquist voltage noise {displaystyle langle V^{2}Rassel } was observed within a small frequency bandwidth {displaystyle Delta nu =Delta omega /(2Pi )} centered around {displaystyle omega =pm omega _{0}} . Somit {displaystyle langle V^{2}rangle approx S_{v}(Omega )times 2Delta nu approx 4Rk_{rm {B}}TDelta nu } General formulation The fluctuation–dissipation theorem can be formulated in many ways; one particularly useful form is the following:[Zitat benötigt].

Lassen {Anzeigestil x(t)} be an observable of a dynamical system with Hamiltonian {Anzeigestil H_{0}(x)} subject to thermal fluctuations. The observable {Anzeigestil x(t)} will fluctuate around its mean value {displaystyle langle xrangle _{0}} with fluctuations characterized by a power spectrum {Anzeigestil S_{x}(Omega )=Winkel {Hut {x}}(Omega ){Hut {x}}^{*}(Omega )Rassel } . Suppose that we can switch on a time-varying, spatially constant field {Anzeigestil f(t)} which alters the Hamiltonian to {Anzeigestil H(x)=H_{0}(x)-f(t)x} . The response of the observable {Anzeigestil x(t)} to a time-dependent field {Anzeigestil f(t)} is characterized to first order by the susceptibility or linear response function {Displaystil Chi (t)} of the system {Anzeigestil Sprache x(t)rangle =langle xrangle _{0}+int _{-unendlich }^{t}!f(Jawohl )chi (t-tau ),dtau ,} where the perturbation is adiabatically (very slowly) switched on at {displaystyle tau =-infty } .

The fluctuation–dissipation theorem relates the two-sided power spectrum (d.h. both positive and negative frequencies) von {Anzeigestil x} to the imaginary part of the Fourier transform {Anzeigestil {Hut {chi }}(Omega )} of the susceptibility {Displaystil Chi (t)} : {Anzeigestil S_{x}(Omega )=-{frac {2k_{Mathrm {B} }T}{Omega }}Name des Bedieners {Ich bin} {Hut {chi }}(Omega ).} Which holds under the Fourier transform convention {Anzeigestil f(Omega )=int _{-unendlich }^{unendlich }f(t)e^{-iomega t},dt} . The left-hand side describes fluctuations in {Anzeigestil x} , the right-hand side is closely related to the energy dissipated by the system when pumped by an oscillatory field {Anzeigestil f(t)=Fsin(omega t+phi )} .

This is the classical form of the theorem; quantum fluctuations are taken into account by replacing {displaystyle 2k_{Mathrm {B} }T/omega } mit {Anzeigestil hbar ,coth(hbar omega /2k_{Mathrm {B} }T)} (whose limit for {displaystyle hbar to 0} ist {displaystyle 2k_{Mathrm {B} }T/omega } ). A proof can be found by means of the LSZ reduction, an identity from quantum field theory.[Zitat benötigt] The fluctuation–dissipation theorem can be generalized in a straightforward way to the case of space-dependent fields, to the case of several variables or to a quantum-mechanics setting.[1] A special case in which the fluctuating quantity is the energy itself is the fluctuation-dissipation theorem for the frequency-dependent specific heat.[5] Derivation Classical version We derive the fluctuation–dissipation theorem in the form given above, using the same notation. Consider the following test case: the field f has been on for infinite time and is switched off at t=0 {Anzeigestil f(t)=f_{0}Theta (-t),} wo {Theta im Display-Stil (t)} is the Heaviside function. We can express the expectation value of {Anzeigestil x} by the probability distribution W(x,0) and the transition probability {Anzeigestil P(x',t|x,0)} {Anzeigestil Sprache x(t)rangle =int dx'int dx,x'P(x',t|x,0)W(x,0).} The probability distribution function W(x,0) is an equilibrium distribution and hence given by the Boltzmann distribution for the Hamiltonian {Anzeigestil H(x)=H_{0}(x)-xf_{0}} {Anzeigestil W.(x,0)={frac {exp(-beta H(x))}{int dx',exp(-beta H(x'))}},,} wo {displaystyle beta ^{-1}=k_{rm {B}}T} . For a weak field {displaystyle beta xf_{0}ll 1} , we can expand the right-hand side {Anzeigestil W.(x,0)approx W_{0}(x)[1+beta f_{0}(x(0)-langle xrangle _{0})],} hier {Anzeigestil W_{0}(x)} is the equilibrium distribution in the absence of a field. Plugging this approximation in the formula for {Anzeigestil Sprache x(t)Rassel } Erträge {Anzeigestil Sprache x(t)rangle =langle xrangle _{0}+beta f_{0}EIN(t),} (*) wo ein(t) is the auto-correlation function of x in the absence of a field: {Anzeigestil A(t)=Winkel [x(t)-langle xrangle _{0}][x(0)-langle xrangle _{0}]rangle _{0}.} Note that in the absence of a field the system is invariant under time-shifts. We can rewrite {Anzeigestil Sprache x(t)rangle -langle xrangle _{0}} using the susceptibility of the system and hence find with the above equation (*) {Anzeigestil f_{0}int _{0}^{unendlich }dtau ,chi (Jawohl )Theta (tau -t)=beta f_{0}EIN(t)} Folglich, {displaystyle -chi (t)=beta {dA(t) over dt}Theta (t).} (**) To make a statement about frequency dependence, it is necessary to take the Fourier transform of equation (**). By integrating by parts, it is possible to show that {Anzeigestil -{Hut {chi }}(Omega )=iomega beta int _{0}^{unendlich }e^{-iomega t}EIN(t),dt-beta A(0).} Seit {Anzeigestil A(t)} is real and symmetric, es folgt dem {displaystyle 2operatorname {Ich bin} [{Hut {chi }}(Omega )]=-omega beta {Hut {EIN}}(Omega ).} Endlich, for stationary processes, the Wiener–Khinchin theorem states that the two-sided spectral density is equal to the Fourier transform of the auto-correlation function: {Anzeigestil S_{x}(Omega )={Hut {EIN}}(Omega ).} Deswegen, es folgt dem {Anzeigestil S_{x}(Omega )=-{frac {2k_{Text{B}}T}{Omega }}Name des Bedieners {Ich bin} [{Hut {chi }}(Omega )].} Quantum version The fluctuation-dissipation theorem relates the correlation function of the observable of interest {displaystyle langle {Hut {x}}(t){Hut {x}}(0)Rassel } (a measure of fluctuation) to the imaginary part of the response function {Anzeigestil {Text{Ich bin}}links[chi (Omega )Rechts]=links[chi (Omega )-chi ^{*}(Omega )Rechts]/2ich} in the frequency domain (a measure of dissipation). A link between these quantities can be found through the so-called Kubo formula[6] {Displaystil Chi (t-t')={frac {ich}{hbar }}Theta (t-t')Winkel [{Hut {x}}(t),{Hut {x}}(t')]Rassel } which follows, under the assumptions of the linear response theory, from the time evolution of the ensemble average of the observable {displaystyle langle {Hut {x}}(t)Rassel } in the presence of a perturbing source. Once Fourier transformed, the Kubo formula allows writing the imaginary part of the response function as {Anzeigestil {Text{Ich bin}}links[chi (Omega )Rechts]={frac {1}{2hbar }}int _{-unendlich }^{+unendlich }Winkel {Hut {x}}(t){Hut {x}}(0)-{Hut {x}}(0){Hut {x}}(t)rangle e^{iomega t}dt.} In the canonical ensemble, the second term can be re-expressed as {displaystyle langle {Hut {x}}(0){Hut {x}}(t)rasseln ={Text{Tr }}e^{-Beta {Hut {H}}}{Hut {x}}(0){Hut {x}}(t)={Text{Tr }}{Hut {x}}(t)e^{-Beta {Hut {H}}}{Hut {x}}(0)={Text{Tr }}e^{-Beta {Hut {H}}}underbrace {e^{Beta {Hut {H}}}{Hut {x}}(t)e^{-Beta {Hut {H}}}} _{{Hut {x}}(t-ihbar beta )}{Hut {x}}(0)=Winkel {Hut {x}}(t-ihbar beta ){Hut {x}}(0)Rassel } where in the second equality we re-positioned {Anzeigestil {Hut {x}}(t)} using the cyclic property of trace. Nächste, in the third equality, we inserted {Anzeigestil e^{-Beta {Hut {H}}}e^{Beta {Hut {H}}}} next to the trace and interpreted {Anzeigestil e^{-Beta {Hut {H}}}} as a time evolution operator {Anzeigestil e^{-{frac {ich}{hbar }}{Hut {H}}Delta t}} with imaginary time interval {displaystyle Delta t=-ihbar beta } . The imaginary time shift turns into a {Anzeigestil e^{-beta hbar omega }} factor after Fourier transform {Anzeigestil int _{-unendlich }^{+unendlich }Winkel {Hut {x}}(t-ihbar beta ){Hut {x}}(0)rangle e^{iomega t}dt=e^{-beta hbar omega }int _{-unendlich }^{+unendlich }Winkel {Hut {x}}(t){Hut {x}}(0)rangle e^{iomega t}dt} and thus the expression for {Anzeigestil {Text{Ich bin}}links[chi (Omega )Rechts]} can be easily rewritten as the quantum fluctuation-dissipation relation [7] {Anzeigestil S_{x}(Omega )=2hbar left[n_{rm {SEIN}}(Omega )+1Rechts]{Text{Ich bin}}links[chi (Omega )Rechts]} where the power spectral density {Anzeigestil S_{x}(Omega )} is the Fourier transform of the auto-correlation {displaystyle langle {Hut {x}}(t){Hut {x}}(0)Rassel } und {Anzeigestil n_{rm {SEIN}}(Omega )=links(e^{beta hbar omega }-1Rechts)^{-1}} is the Bose-Einstein distribution function. The same calculation also yields {Anzeigestil S_{x}(-Omega )=e^{-beta hbar omega }S_{x}(Omega )=2hbar left[n_{rm {SEIN}}(Omega )Rechts]{Text{Ich bin}}links[chi (Omega )Rechts]neq S_{x}(+Omega )} daher, differently from what obtained in the classical case, the power spectral density is not exactly frequency-symmetric in the quantum limit. Consistently, {displaystyle langle {Hut {x}}(t){Hut {x}}(0)Rassel } has an imaginary part originating from the commutation rules of operators.[8] The additional " {Anzeigestil +1} " term in the expression of {Anzeigestil S_{x}(Omega )} at positive frequencies can also be thought of as linked to spontaneous emission. An often cited result is also the symmetrized power spectral density {Anzeigestil {frac {S_{x}(Omega )+S_{x}(-Omega )}{2}}=2hbar left[n_{rm {SEIN}}(Omega )+{frac {1}{2}}Rechts]{Text{Ich bin}}links[chi (Omega )Rechts]=hbar coth left({frac {hbar omega }{2k_{B}T}}Rechts){Text{Ich bin}}links[chi (Omega )Rechts].} Das " {Anzeigestil +1/2} " can be thought of as linked to quantum fluctuations, or to zero-point motion of the observable {Anzeigestil {Hut {x}}} . At high enough temperatures, {Anzeigestil n_{rm {SEIN}}ca (beta hbar omega )^{-1}gg 1} , d.h. the quantum contribution is negligible, and we recover the classical version.

Violations in glassy systems While the fluctuation–dissipation theorem provides a general relation between the response of systems obeying detailed balance, when detailed balance is violated comparison of fluctuations to dissipation is more complex. Below the so called glass temperature {Anzeigestil T_{rm {g}}} , glassy systems are not equilibrated, and slowly approach their equilibrium state. This slow approach to equilibrium is synonymous with the violation of detailed balance. Thus these systems require large time-scales to be studied while they slowly move toward equilibrium.

To study the violation of the fluctuation-dissipation relation in glassy systems, particularly spin glasses, Ref.[9] performed numerical simulations of macroscopic systems (d.h. large compared to their correlation lengths) described by the three-dimensional Edwards-Anderson model using supercomputers. In their simulations, the system is initially prepared at a high temperature, rapidly cooled to a temperature {displaystyle T=0.64T_{rm {g}}} below the glass temperature {Anzeigestil T_{g}} , and left to equilibrate for a very long time {Anzeigestil t_{rm {w}}} under a magnetic field {Anzeigestil H} . Dann, at a later time {displaystyle t+t_{rm {w}}} , two dynamical observables are probed, namely the response function {Displaystil Chi (t+t_{rm {w}},t_{rm {w}})equiv left.{frac {partial m(t+t_{rm {w}})}{partial H}}Rechts|_{H=0}} and the spin-temporal correlation function {Anzeigestil C(t+t_{rm {w}},t_{rm {w}})Äquiv {frac {1}{v}}left.sum _{x}langle S_{x}(t_{rm {w}})S_{x}(t+t_{rm {w}})rangle right|_{H=0}} wo {Anzeigestil S_{x}=pm 1} is the spin living on the node {Anzeigestil x} of the cubic lattice of volume {Anzeigestil V} , und {textstyle m(t)Äquiv {frac {1}{v}}Summe _{x}langle S_{x}(t)Rassel } is the magnetization density. The fluctuation-dissipation relation in this system can be written in terms of these observables as {displaystyle Tchi (t+t_{rm {w}},t_{rm {w}})=1-C(t+t_{rm {w}},t_{rm {w}})} Their results confirm the expectation that as the system is left to equilibrate for longer times, the fluctuation-dissipation relation is closer to be satisfied.

In the mid-1990s, in the study of dynamics of spin glass models, a generalization of the fluctuation–dissipation theorem was discovered [10] that holds for asymptotic non-stationary states, where the temperature appearing in the equilibrium relation is substituted by an effective temperature with a non-trivial dependence on the time scales. This relation is proposed to hold in glassy systems beyond the models for which it was initially found.

Quantum version The Rényi entropy as well as von Neumann entropy in quantum physics are not observables since they depend nonlinearly on the density matrix. Recently, Mohammad H. Ansari and Yuli V. Nazarov proved an exact correspondence that reveals the physical meaning of the Rényi entropy flow in time. This correspondence is similar to the fluctuation-dissipation theorem in spirit and allows the measurement of quantum entropy using the full counting statistics (FCS) of energy transfers.[11][12][13] See also Non-equilibrium thermodynamics Green–Kubo relations Onsager reciprocal relations Equipartition theorem Boltzmann distribution Dissipative system Notes ^ Jump up to: a b H.B.
