Exact nonequilibrium steady states of boundary driven circuit with XYZ gates

Xin Zhang, Tomaz Prosen, Vladislav Popkov

We obtain the exact many-body density operator of a boundary-driven XXZ quantum circuit via a spatially inhomogeneous matrix product Ansatz. The Ansatz has formally infinite bond-d…

Exact Steady State of a One-end Driven XXZ Spin Chain with Boundary Field

V. Popkov, T. Prosen

We find an exact nonequilibrium steady state of an open dissipatively driven XXZ spin-1/2 chain with source or sink spin bath at one end and an arbitrary boundary field at the othe…

Chiral eigenbases of the XX and XY quantum spin chains

Xin Zhang, Frank Göhmann, Andreas Klümper +1

We calculate the values of observables in chiral eigenstates of the XX quantum spin chain that were introduced in previous work and compare the form of the result with the respecti…

Dissipatively dressed quasiparticles in boundary driven integrable spin chains

Vladislav Popkov, Xin Zhang, Carlo Presilla +1

The nonequilibrium steady state (NESS) of integrable spin chains experiencing strong boundary dissipation is accounted by introducing quasiparticles with a renormalized -- dissipat…

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…
