Quantum Non-Equilibrium Steady States Induced by Repeated Interactions
Dragi Karevski, Thierry Platini
We study the steady state of a finite XX chain coupled at its boundaries to quantum reservoirs made of free spins that interact one after the other with the chain. The two-point co…
Out-of-equilibrium bosons on a one-dimensional optical random lattice
Thierry Platini, Rosemary J. Harris, Dragi Karevski
We study the transport properties of a one-dimensional hard-core boson lattice gas coupled to two particle reservoirs at different chemical potentials generating a current flow thr…
Ising Quantum Chains
Dragi Karevski
The aim of this article is to give a pedagogical introduction to the exact equilibrium and nonequilibrium properties of free fermionic quantum spin chains. In a first part we prese…
Random Ising model in three dimensions: theory, experiment and simulation - a difficult coexistence
Bertrand Berche, Pierre-Emmanuel Berche, Christophe Chatelain +1
We discuss different approaches for studying the influence of disorder in the three-dimensional Ising model. From the theoretical point of view, renormalisation group calculations…
