Charge and spin current statistics of the open Hubbard model with weak coupling to the environment
Berislav Buča, Tomaž Prosen
Izvirni znanstveni članek
Oznake: kvantna mehanika;statistična fizika;odprti sistemi;quantum mechanics;statistical physics;open systems;
Based on generalization and extension of our previous work [Phys. Rev. Lett. 112, 067201 (2014)] to multiple independent Markovian baths we will compute the charge and spin current statistics of the open Hubbard model with weak system-bath coupling up to next-to-leading order in the coupling paramet ...

Exact matrix product decay modes of a boundary driven cellular automaton
Tomaž Prosen, Berislav Buča
Izvirni znanstveni članek
Oznake: markovske verige;integrabilnost;celični avtomati;Markov chains;integrability;reversible cellular automaton;nonequilibrium steady state;
We study integrability properties of a reversible deterministic cellular automaton (Rule 54 of (Bobenko et al 1993 Commun. Math. Phys. 158 127)) and present a bulk algebraic relation and its inhomogeneous extension which allow for an explicit construction of Liouvillian decay modes for two distinct ...

Strongly correlated non-equilibrium steady states with currents - quantum and classical picture
Berislav Buča, Tomaž Prosen
Pregledni znanstveni članek
Oznake: kvantna mehanika;klasični modeli;močno korelirani sistemi;neravnovesni sistemi;quantum mechanics;classical models;strongly correlated systems;non-equilibrium systems;
In this minireview we will discuss recent progress in the analytical study of current-carrying non-equilibrium steady states (NESS) that can be constructed in terms of a matrix product ansatz. We will focus on one-dimensional exactly solvable strongly correlated cases, and will study both quantum mo ...

Rule 54: exactly solvable model of nonequilibrium statistical mechanics
Berislav Buča, Katja Klobas, Tomaž Prosen
Izvirni znanstveni članek
Oznake: statistična mehanika;neravnovesni sistemi;celični avtomati;termalizacija;statistical mechanics;non-equilibrium systems;cellular automata;thermalization;
We review recent results on an exactly solvable model of nonequilibrium statistical mechanics, specifically the classical rule 54 reversible cellular automaton and some of its quantum extensions. We discuss the exact microscopic description of nonequilibrium dynamics as well as the equilibrium and n ...

Exact large deviation statistics and trajectory phase transition of a deterministic boundary driven cellular automaton
Berislav Buča, Juan P. Garrahan, Tomaž Prosen, Matthieu Vanicat
Izvirni znanstveni članek
Oznake: neravnovesna statistična mehanika;celični avtomati;nonequilibrium statistical physics;cellular automata;
We study the statistical properties of the long-time dynamics of the rule 54 reversible cellular automaton (CA), driven stochastically at its boundaries. This CA can be considered as a discrete-time and deterministic version of the Fredrickson-Andersen kinetically constrained model (KCM). By means o ...
