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…
Dynamical approach to chains of scatterers
Martin Horvat, Tomaz Prosen
Linear chains of quantum scatterers are studied in the process of lengthening, which is treated and analysed as a discrete dynamical system defined over the manifold of scattering…
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,…
Operator space entanglement entropy in transverse Ising chain
Tomaz Prosen, Iztok Pizorn
The efficiency of time dependent density matrix renormalization group methods is intrinsically connected with the rate of entanglement growth. We introduce a new measure of entangl…
The bends on a quantum waveguide and cross-products of Bessel functions
Martin Horvat, Tomaz Prosen
A detailed analysis of the wave-mode structure in a bend and its incorporation into a stable algorithm for calculation of the scattering matrix of the bend is presented. The calcul…
Chaos and Complexity of quantum motion
Tomaz Prosen
The problem of characterizing complexity of quantum dynamics - in particular of locally interacting chains of quantum particles - will be reviewed and discussed from several differ…
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…
