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 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…
