Physical constraints on effective non-Hermitian systems

quant-ph · 2025-08-28 · unverdicted · novelty 5.0 · 2 refs

Effective non-Hermitian systems with interactions are incompatible with direct inclusion of anti-Hermitian terms in Matsubara Green's functions and are instead described by pseudo-Hermitian quantum mechanics.
