Complexity of thermal states in quantum spin chains
Marko Znidaric, Tomaz Prosen, Iztok Pizorn
We study quantum correlations and complexity of simulation, characterized by quantum mutual information and entanglement entropy in operator space respectively, for thermal states…
Quantum phase transition in a far from equilibrium steady state of XY spin chain
Tomaz Prosen, Iztok Pizorn
Using quantization in the Fock space of operators we compute the non-equilibrium steady state in an open Heisenberg XY spin 1/2 chain of finite but large size coupled to Markovian…
The two-body random spin ensemble and a new type of quantum phase transition
Iztok Pizorn, Tomaz Prosen, Stefan Mossmann +1
We study the properties of a two-body random matrix ensemble for distinguishable spins. We require the ensemble to be invariant under the group of local transformations and analyze…
Loschmidt echoes in two-body random matrix ensembles
Iztok Pizorn, Tomaz Prosen, Thomas H. Seligman
Fidelity decay is studied for quantum many-body systems with a dominant independent particle Hamiltonian resulting e.g. from a mean field theory with a weak two-body interaction. T…
