Rotation-time symmetry in bosonic systems and the existence of exceptional points in the absence of [Formula: see text] symmetry
We study symmetries of open bosonic systems in the presence of laser pumping. Non-Hermitian Hamiltonians describing these systems can be parity-time ([Formula: see text] ) symmetric in special cases only. Systems exhibiting this symmetry are characterised by real-valued energy spectra and can displa...
