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…

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…
