We consider an open (Brownian) classical harmonic oscillator in contact with a non-Markovian thermal bath and described by the generalized Langevin equation. When the bath's spectrum has a finite upper cutoff frequency, the oscillator may have ergodic and nonergodic configurations. In ergodic configurations (when they exist, they correspond to lower oscillator frequencies) the oscillator demonstrates conventional relaxation to thermal equilibrium with the bath. In nonergodic configurations… 



Localized mode and nonergodicity of a harmonic oscillator chain

We present a simple and microscopic physical model that breaks the ergodicity. Our model consists of coupled classical harmonic oscillators, and the motion of the tagged particle obeys the

Non-Markovian Brownian dynamics and nonergodicity.

We report the breaking of ergodicity for a class of generalized, Brownian motion obeying a non-Markovian dynamics being driven by a generalized Langevin equation (GLE). This very feature originates

Equilibration problem for the generalized Langevin equation

We consider the problem of equilibration of a single-oscillator system with dynamics given by the generalized classical Langevin equation. It is well known that this dynamics can be obtained if one

It has been shown that the Jarzynski equality is valid in nondissipative nonergodic open oscillator systems regardless of the rate of applied ramp force.

Markovian embedding of non-Markovian superdiffusion.

This work considers different Markovian embedding schemes of non-Markovian stochastic processes that are described by generalized Langevin equations and obey thermal detailed balance under equilibrium conditions and finds that intermediate asymptotics exhibit a giant enhancement of superdiffusion in tilted washboard potentials.

Efficiency and, in particular, efficiency at maximum power can be discussed systematically beyond the linear response regime for two classes of molecular machines, isothermal ones such as molecular motors, and heat engines such as thermoelectric devices, using a common framework based on a cycle decomposition of entropy production.

Non-Clausius heat transfer: The method of the nonstationary Langevin equation.

This work discusses two scenarios when the Clausius statement that heat does not spontaneously flow from cold to hot does not hold, and suggests that the energy transfer may be consistent with the statement on a coarse-grained timescale, but be anomalously directed during time intervals shorter than the thermalization time.

Thermalization in open classical systems with finite heat baths

Abstract.We discuss thermalization of a test particle schematized as a harmonic oscillator and coupled to a Boltzmann heat bath of finite size and with a finite bandwidth for the frequencies of its

Kinetic and Hydrodynamic Scalings in an Exactly-Soluble Model for the Brownian Motion

The macroscopic system exhibits hierarchical dynamic processes with different time scales, each level of which has a characteristic scaling. This important feature is rigorously investigated for the
