Universal Constraints on Relaxation Times for d-level GKLS master equations

Autor: Gen Kimura, Kyouhei Watanabe, Shigeru Ajisaka

In 1976, Gorini, Kossakowski, Sudarshan and Lindblad independently discovered a general form of master equations for an open quantum Markovian dynamics. In honor of all the authors, the equation is nowadays called the GKLS master equation. In this pa

Giant nonlinear conduction in the charge ordered organic conductor θ ‐ ( BEDT ‐ TTF ) 2 MM ′ ( SCN ) 4 ( M = Cs , Rb; M ′ = Co , Zn) is analyzed in relation to the current-induced suppression of the charge ordered state characterized by a wa

We study nonequilibrium quantum phase transitions in XY spin 1/2 chain using the $C^*$ algebra. We show that the well-known quantum phase transition at magnetic field $h = 1$ persists also in the nonequilibrium setting as long as one of the reservoir

We study particle current in a recently proposed model for coherent quantum transport. In this model, a system connected to mesoscopic Fermi reservoirs (meso-reservoir) is driven out of equilibrium by the action of super-reservoirs thermalized to pre

We study a model of nonequilibrium quantum transport of particles and energy in a many-body system connected to mesoscopic Fermi reservoirs (the so-called meso-reservoirs). We discuss the conservation laws of particles and energy within our setup as
