We study the entropy production of a microscopic model for nonequilibrium wetting. We show that, in contrast to the equilibrium case, a bound interface in a nonequilibrium steady state produces entropy. Interestingly, in some regions of the phase diagram a bound interface produces more entropy than a free interface. Moreover, by solving exactly a four-site system, we find that the first derivative of the entropy production with respect to the control parameter displays a discontinuity at the…

Entropy production as a tool for characterizing nonequilibrium phase transitions.
This work paves the way to a systematic description and classification of nonequilibrium phase transitions through a key indicator of system irreversibility.
Exponential volume dependence of entropy-current fluctuations at first-order phase transitions in chemical reaction networks.
It is shown that the fluctuations of the entropy production have an exponential volume-dependence when the system is bistable and the exponential prefactor is the height of the effective potential barrier between the two fixed-points.
We investigate the nonequilibrium roughening transition of a one-dimensional restricted solid-on-solid model by directly sampling the stationary probability density of a suitable order parameter as

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.
Precision and dissipation of a stochastic Turing pattern.
It is argued that larger fluctuations can also have a positive effect on the precision of the pattern, and increasing the thermodynamic cost beyond this value makes the pattern less precise.
Phase transition in thermodynamically consistent biochemical oscillators.
This work shows that biochemical oscillations emerge through a generic nonequilibrium phase transition, with a characteristic qualitative behavior at criticality, and argues that the number of coherent oscillations is more appropriate to quantify the precision of biochemical oscillation.
Derivation of Markov processes that violate detailed balance.
It is shown that for a Markov model without detailed balance, an extended Markov models can be constructed, which explicitly includes the degrees of freedom for the driving agent and satisfies the detailed balance condition.


Entropy production in nonequilibrium systems at stationary states.
A stochastic approach to nonequilibrium thermodynamics based on the expression of the entropy production rate advanced by Schnakenberg for systems described by a master equation is presented, finding a singularity at the critical point of the linear-logarithm type.
Entropy production in the nonequilibrium steady states of interacting many-body systems.
It is shown that the large deviation function displays a kink-like feature at zero entropy production that is similar to that observed for a single particle driven along a periodic potential.
Entropy production and fluctuation relations for a KPZ interface
We study entropy production and fluctuation relations in the restricted solid-on-solid growth model, which is a microscopic realization of the Kardar–Parisi–Zhang (KPZ) equation. Solving the
Finite size effects in nonequilibrium wetting
Models with a nonequilibrium wetting transition display a transition also in finite systems. This is different from nonequilibrium phase transitions into an absorbing state, where the stationary
Entropy production of cyclic population dynamics.
The entropy production is calculated for a population model that displays nonequilibrium behavior resulting from cyclic competition and shows that the entropy production peaks very close to the critical point and tends to zero upon deviating from it.
Nonequilibrium wetting
When a nonequilibrium growing interface in the presence of a wall is considered a nonequilibrium wetting transition may take place. This transition can be studied trough Langevin equations or
Non-equilibrium Dynamics, Thermalization and Entropy Production
This paper addresses fundamental aspects of statistical mechanics such as the motivation of a classical state space with spontaneous transitions, the meaning of non-equilibrium in the context of
Entropy production along a stochastic trajectory and an integral fluctuation theorem.
The integrated sum of both Delatas(tot) is shown to obey a fluctuation theorem (exp([-Deltas( tot) = 1 for arbitrary initial conditions and arbitrary time-dependent driving over a finite time interval)).
Wetting under nonequilibrium conditions.
A mean-field approximation is shown to reproduce the main features of the phase diagram of a recently introduced model for nonequilibrium wetting in (1+1) dimensions, while providing indications for the behavior of the wetting transition in higher dimensions.

The fluctuation theorem is derived for stochastic nonequilibrium reactions ruled by the chemical master equation and verified in the Schlögl model of far-from-equilibrium bistability.
