Spread of Entanglement in Generalized Kicked Ising Chain
Tanay Pathak, Hiromi Ebisu, Tomaž Prosen
We investigate the dynamics of entanglement in a generalized version of the kicked Ising chain, extending the model from the standard qubit case (local dimension ) to higher l…
Bethe-ansatz diagonalization of steady state of boundary driven integrable spin chains
Vladislav Popkov, Xin Zhang, Carlo Presilla +1
We find that the density operator of non-equilibrium steady state (NESS) of XXZ spin chain with strong ``sink and source" boundary dissipation, can be described in terms of quasipa…
Exact NESS of XXZ circuits boundary driven with arbitrary resets or fields
Vladislav Popkov, Tomaž Prosen
We propose spatially inhomogeneous matrix product ansatz for an exact many-body density operator of a boundary driven XXZ quantum circuit. The ansatz has formally infinite bond-dim…
Loss-induced quantum information jet in an infinite temperature Hubbard chain
Patrik Penc, CÄtÄlin PaÅcu Moca, Ãrs Legeza +3
Information propagation in the one-dimensional infinite temperature Hubbard model with a dissipative particle sink at the end of a semi-infinite chain is studied. In the strongly i…
Ergodicity breaking and deviation from Eigenstate Thermalisation in relativistic QFT
Miha Srdinšek, Tomaž Prosen, Spyros Sotiriadis
The validity of the ergodic hypothesis in quantum systems can be rephrased in the form of the eigenstate thermalisation hypothesis (ETH), a set of statistical properties for the ma…
