Dynamical equivalence classes for Markov jump processes

Gatien Verley

Two different Markov jump processes driven out of equilibrium by constant thermodynamic forces may have identical current fluctuations in the stationary state. The concept of dynam…

Effective Hamiltonians and Lagrangians for conditioned Markov processes at large volume

Lydia Chabane, Alexandre Lazarescu, Gatien Verley

When analysing statistical systems or stochastic processes, it is often interesting to ask how they behave given that some observable takes some prescribed value. This conditioning…

Efficiency fluctuations of stochastic machines undergoing a phase transition

Hadrien Vroylandt, Massimiliano Esposito, Gatien Verley

We study the efficiency fluctuations of a stochastic heat engine made of interacting unicyclic machines and undergoing a phase transition in the macroscopic limit. Depending on…

An ordered set of power-efficiency trade-offs

Hadrien Vroylandt, David Lacoste, Gatien Verley

In this paper, we derive a number of inequalities which express power-efficiency trade-offs that hold generally for thermodynamic machines operating in non-equilibrium stationary s…

Non equivalence of dynamical ensembles and emergent non ergodicity

Hadrien Vroylandt, Gatien Verley

Dynamical ensembles have been introduced to study constrained stochastic processes. In the microcanonical ensemble, the value of a dynamical observable is constrained to a given va…

The unlikely Carnot efficiency

Gatien Verley, Tim Willaert, Christian Van den Broeck +1

The efficiency of an heat engine is traditionally defined as the ratio of its average output work over its average input heat. Its highest possible value was discovered by Carnot i…
