Title: Potential of Entropic Force in Markov Systems with Nonequilibrium Steady State, Generalized Gibbs Function and Criticality

Abstract

In this paper we revisit the notion of the “minus logarithm of stationary probability” as a generalized potential in nonequilibrium systems and attempt to illustrate its central role in an axiomatic approach to stochastic nonequilibrium thermodynamics of complex systems. It is demonstrated that this quantity arises naturally through both monotonicity results of Markov processes and as the rate function when a stochastic process approaches a detrministic limit. We then undertake a more detailed mathematical analysis of the consequences of this quantity, culminating in a necessary and sufficient condition for the criticality of stochastic systems. This condition is then discussed in the context of recent results about criticality in biological systems.

  • We study the real time dynamics of a dissipative quantum system in a metastable state which may decay by crossing a potential barrier. Starting from an initial state where the system is in thermal equilibrium on one side of the barrier, the time evolution of the density matrix is evaluated analytically in the semiclassical approximation for coordinates near the barrier top. In a region about a critical temperature T{sub c} large quantum fluctuations render the harmonic approximation of the potential insufficient and anharmonicities become essential. Accounting for non-Gaussian fluctuation modes, we show that the density matrix approaches a quasistationary statemore » with a constant flux across the barrier. This extends our earlier results [Phys. Rev. E {bold 51}, 4267 (1995)] on the quantum generalization of the Kramers flux state to the region about T{sub c}. By matching the flux state onto the equilibrium state on one side of the barrier, we determine the decay rate out of the metastable state. The rate constant shows a changeover from thermally activated decay to quantum tunneling for temperatures below T{sub c}. {copyright} {ital 1997} {ital The American Physical Society}« less
  • Liouville{close_quote}s best-known theorem, {dot f}({l_brace}q,p{r_brace},t)=0, describes the incompressible flow of phase-space probability density, f({l_brace}q,p{r_brace},t). This incompressible-flow theorem follows directly from Hamilton{close_quote}s equations of motion. It applies to simulations of isolated systems composed of interacting particles, whether or not the particles are confined by a box potential. Provided that the particle{endash}particle and particle{endash}box collisions are sufficiently mixing, the long-time-averaged value {l_angle}f{r_angle} approaches, in a {open_quotes}coarse-grained{close_quotes} sense, Gibbs{close_quote} equilibrium microcanonical probability density, f{sub eq}, from which all equilibrium properties follow, according to Gibbs{close_quote} statistical mechanics. All these ideas can be extended to many-body simulations of deterministic open systems with nonequilibrium boundary conditionsmore » incorporating heat transfer. Then Liouville{close_quote}s compressible phase-space-flow theorem{emdash}in the original {dot f}{ne}0 form{emdash}applies. I illustrate and contrast Liouville{close_quote}s two theorems for two simple nonequilibrium systems, in each case considering both stationary and time-dependent cases. Gibbs{close_quote} distributions for incompressible (equilibrium) flows are typically smooth. Surprisingly, the long-time-averaged phase-space distributions of nonequilibrium compressible-flow systems are instead singular and {open_quotes}multifractal.{close_quotes} The nonequilibrium analog of Gibbs{close_quote} entropy, S{equivalent_to}{minus}k{l_angle}lnf{r_angle}, diverges, to {minus}{infinity}, in such a case. Gibbs{close_quote} classic remedy for such entropy errors was to {open_quotes}coarse-grain{close_quotes} the probability density{emdash}by averaging over finite cells of dimensions {product}{Delta}qthinsp{Delta}p. Such a coarse graining is effective for isolated systems approaching equilibrium, and leads to a unique entropy. Coarse graining is not as useful for deterministic open systems, constrained so as to describe stationary nonequilibrium states. Such systems have a Gibbs{close_quote} entropy which depends, logarithmically, upon the grain size. The two Liouville{close_quote}s theorems, their applications to Gibbs{close_quote} entropy, and to the grain-size dependence of that entropy, are clearly illustrated here with simple example problems. {copyright} {ital 1998 American Institute of Physics.}« less

  • We established a theoretical framework in terms of the curl flux, population landscape, and coherence for non-equilibrium quantum systems at steady state, through exploring the energy and charge transport in molecular processes. The curl quantum flux plays the key role in determining transport properties and the system reaches equilibrium when flux vanishes. The novel curl quantum flux reflects the degree of non-equilibriumness and the time-irreversibility. We found an analytical expression for the quantum flux and its relationship to the environmental pumping (non-equilibriumness quantified by the voltage away from the equilibrium) and the quantum tunneling. Furthermore, we investigated another quantum signature,more » the coherence, quantitatively measured by the non-zero off diagonal element of the density matrix. Populations of states give the probabilities of individual states and therefore quantify the population landscape. Both curl flux and coherence depend on steady state population landscape. Besides the environment-assistance which can give dramatic enhancement of coherence and quantum flux with high voltage at a fixed tunneling strength, the quantum flux is promoted by the coherence in the regime of small tunneling while reduced by the coherence in the regime of large tunneling, due to the non-monotonic relationship between the coherence and tunneling. This is in contrast to the previously found linear relationship. For the systems coupled to bosonic (photonic and phononic) reservoirs the flux is significantly promoted at large voltage while for fermionic (electronic) reservoirs the flux reaches a saturation after a significant enhancement at large voltage due to the Pauli exclusion principle. In view of the system as a quantum heat engine, we studied the non-equilibrium thermodynamics and established the analytical connections of curl quantum flux to the transport quantities such as energy (charge) transfer efficiency, chemical reaction efficiency, energy dissipation, heat and electric currents observed in the experiments. We observed a perfect transfer efficiency in chemical reactions at high voltage (chemical potential difference). Our theoretical predicted behavior of the electric current with respect to the voltage is in good agreements with the recent experiments on electron transfer in single molecules.« less
