Scale-free non-Hermitian skin effect in a boundary-dissipated spin chain

Scale-free non-Hermitian skin effect in a boundary-dissipated spin chain

We study the open XXZ spin chain with a $PT$-symmetric non-Hermitian boundary field. We find an interaction-induced scale-free non-Hermitian skin effect by using the coordinate Bethe Ansatz. The steady-state and the ground state in the $PT$ broken phase are constructed, and the formulas of their eig...
