Non-dissipative effects in nonequilibrium systems
نویسنده
چکیده
We consider aspects of nonequilibrium statistical mechanics that have traditionally not been considered in irreversible thermodynamics. More specifically we refer to the frenetic contribution in fluctuation and response theory, which complements the entropic component. Frenesy then refers to an amount of volatility or of dynamical activity defined on trajectories in some reduced description. It is a time-symmetric quantity and its recurrent appearance in nonequilibrium studies give it some first operational meaning.

Oscillatory dynamics and non-Markovian memory in dissipative quantum systems.
The nonequilibrium dynamics of a small quantum system coupled to a dissipative environment is studied. We show that (i) the oscillatory dynamics close to a coherent-to-incoherent transition is significantly different from the one of the classical damped harmonic oscillator and that (ii) non-Markovian memory plays a prominent role in the time evolution after a quantum quench.
متن کاملSlip Effects on Ohmic Dissipative Non-Newtonian Fluid Flow in the Presence of Aligned Magnetic Field
The present paper deals with the effects of Ohmic dissipative Casson fluid flow over a stretching sheet in the presence of aligned magnetic field. The present phenomenon also includes the interaction of thermal radiation and velocity slip. The governing boundary layer equations are transformed into a set of ordinary differential equations using the similarity transformations. The dimensionless ...
متن کاملPassivity and Passive Feedback Stabilization for a Class of Mixed Potential Systems
This paper studies the input-output properties of a class of control affine systems where the drift dynamics is generated by a metriplectic structure. Those systems, related to generalized (or dissipative) Hamiltonian systems, are generated by a conserved component and a dissipative component and appear, for example, in non-equilibrium thermodynamics. In nonequilibrium thermodynamics, the two p...
متن کاملEnergy Profile Fluctuations in Dissipative Nonequilibrium Stationary States
The exact large deviation function (ldf) for the fluctuations of the energy density field is computed for a chain of Ising (or more generally Potts) spins driven by a zero-temperature (dissipative) Glauber dynamics and sustained in a non trivial stationary regime by an arbitrary energy injection mechanism at the boundary of the system. It is found that this ldf is independent of the dynamical d...
متن کاملDissipative electromagnetism from a nonequilibrium thermodynamics perspective.
Dissipative effects in electromagnetism on macroscopic scales are examined by coarse-graining the microscopic Maxwell equations with respect to time. We illustrate a procedure to derive the dissipative effects on the macroscopic scale by using a Green-Kubo type expression in terms of the microscopic fluctuations and the correlations between them. The resulting macroscopic Maxwell equations are ...
