Entropy Maximization and Weak Gibbsianity of Quasi-Free Fermionic States
Vojkan JakÅ¡iÄ, Vojkan Jakšić, Claude-Alain Pillet +1
In their 1972 study of approach to equilibrium, Lanford and Robinson showed that gauge-invariant quasi-free states of lattice fermions maximize entropy among all translation-invari…

Fluctuation Theorem and Thermodynamic Formalism
Noé Cuneo, Vojkan JakÅ¡iÄ, Claude-Alain Pillet +1
We study the Fluctuation Theorem (FT) for entropy production in chaotic discrete-time dynamical systems on compact metric spaces, and extend it to empirical measures, all continuou…

Entropic Fluctuation Theorems for the Spin-Fermion Model
Tristan Benoist, Laurent Bruneau, Vojkan JakÅ¡iÄ +2
We study entropic fluctuations in the Spin-Fermion model describing an -level quantum system coupled to several independent thermal free Fermi gas reservoirs. We establish the q…
