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…
Non-universal level statistics in a chaotic quantum spin chain
Carlos Pineda, Tomaž Prosen
We study the level statistics of an interacting multi-qubit system, namely the kicked Ising spin chain, in the regime of quantum chaos. Long range quasi-energy level statistics sho…
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…
