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…
