Non-Hermitian Absorption Spectroscopy

  title={Non-Hermitian Absorption Spectroscopy},
  author={Kai Li and Yong Xu},
While non-Hermitian Hamiltonians have been experimentally realized in cold atom systems, it remains an outstanding open question of how to experimentally measure their complex energy spectra in momentum space for a realistic system with boundaries. The existence of non-Hermitian skin effects may make the question even more difficult to address given the fact that energy spectra for a system with open boundaries are dramatically different from those in momentum space; the fact may even lead to…
