Query: Non-Bloch topological invariants in a non-Hermitian domain-wall system   We study non-Bloch bulk-boundary correspondence in a non-Hermitian
Su-Schieffer-Heeger model in a domain-wall configuration where the left and
right bulks have different parameters. Focusing on the case where chiral
symmetry is still conserved, we show that non-Hermitian skin effects of bulk
states persist in the system, while the definition of the non-Bloch winding
number of either bulk depends on parameters on both sides of the boundary.
Under these redefined non-Bloch topological invariants, we confirm non-Bloch
bulk-boundary correspondence under the domain-wall configuration, which
exemplifies the impact of boundary conditions in non-Hermitian topological
systems.
