Polarization and entanglement spectrum in non-hermitian systems
Carlos Ortega-Taberner, Lukas Rødland, Maria Hermanns
The entanglement spectrum is a useful tool to study topological phases of matter, and contains valuable information about the ground state of the system. Here, we study its propert…

On the relation of the entanglement spectrum to the bulk polarization
Carlos Ortega-Taberner, Maria Hermanns
The bulk polarization is a topological invariant characterizing non-interacting systems in one dimension with chiral or particle-hole symmetries. We show that the bu…
