Dephasing-induced diffusive transport in anisotropic Heisenberg model
Marko Znidaric
We study transport properties of anisotropic Heisenberg model in a disordered magnetic field experiencing dephasing due to external degrees of freedom. In the absence of dephasing…
Thermalization and ergodicity in many-body open quantum systems
Marko Znidaric, Tomaz Prosen, Giuliano Benenti +2
We study thermalization in many-body quantum systems locally coupled to an external bath. It is shown that quantum chaotic systems do thermalize, that is, they exhibit relaxation t…
Quantum circuit for three-qubit random states
Olivier Giraud, Marko Znidaric, Bertrand Georgeot
We explicitly construct a quantum circuit which exactly generates random three-qubit states. The optimal circuit consists of three CNOT gates and fifteen single qubit elementary ro…
Charge and spin transport in strongly correlated one-dimensional quantum systems driven far from equilibrium
Giuliano Benenti, Giulio Casati, Tomaz Prosen +2
We study the charge conductivity in one-dimensional prototype models of interacting particles, such as the Hubbard and the t-V spinless fermion model, when coupled to some external…
