Nonreciprocity combined with open boundaries and symmetry defects produces a domain-wall traveling-wave phase and anomalous chiral relaxation in open quantum systems.
Minimal pseudo-Lorentz-symmetry-breaking Hamiltonian deformations act as bulk probes that separate renormalizable observables from those carrying irreducible non-Hermitian structure in two-dimensional Dirac semimetals with real spectra.
In the non-Hermitian Kitaev chain, preserved particle-hole symmetry makes the open-chain topological transition coincide with the periodic one and forces zero-energy Majorana modes to appear as reciprocal localization pairs that cancel the non-Hermitian skin effect.

Symmetry and Topology in a Non-Hermitian Kitaev chain
In the non-Hermitian Kitaev chain, preserved particle-hole symmetry makes the open-chain topological transition coincide with the periodic one and forces zero-energy Majorana modes to appear as reciprocal localization pairs that cancel the non-Hermitian skin effect.
