Dissipative two-dimensional Raman lattice

We show that a dissipative two-dimensional Raman lattice can be engineered in two-component ultracold atomic gas, where the interplay of spin-orbit coupling and lightinduced atom loss gives rise to density flow diagonal underlying square lattice. The is driven by non-Hermitian corner skin effect, under which eigenstates localize toward one system. illustrate topological edge states system only accounted for non-Bloch band theory deformation bulk are explicitly considered. directional detected through dynamic evolution an initially localized condensate lattice, or introducing immobile impurity species interact spin-selectively with ground state
