Topological energy braiding of non-Bloch bands
Topological energy braiding of non-Bloch bands
The non-Hermitian skin effect, as a unique feature of non-Hermitian systems, will break the topological energy braiding of Bloch bands in open boundary systems. Going beyond the Bloch band theory, we unveil the energy braiding of non-Bloch bands by introducing a one-dimensional non-Hermitian tight-binding model. We find a generic class …
