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…
Detecting entanglement of random states with an entanglement witness
Marko Znidaric, Tomaz Prosen, Giuliano Benenti +1
The entanglement content of high-dimensional random pure states is almost maximal, nevertheless, we show that, due to the complexity of such states, the detection of their entangle…
Many body localization in Heisenberg XXZ magnet in a random field
Marko Znidaric, Tomaz Prosen, Peter Prelovsek
We numerically investigate Heisenberg XXZ spin-1/2 chain in a spatially random static magnetic field. We find that tDMRG simulations of time evolution can be performed efficiently,…
Negative differential conductivity in Heisenberg XXZ chain far from equilibrium
Tomaz Prosen
Negative differential conductivity is reported for the far from equilibrium quantum spin transport in the insulating regime (J_x < J_z) of finite Heisenberg XXZ spin 1/2 chains. Th…
