Non-Hermitian systems with a real spectrum and selective skin effect
Li Ge
In this work we first show a simple approach to constructing non-Hermitian Hamiltonians with a real spectrum, which are \textit{not} obtained by a non-unitary transformation such a…

Effective size of a parity-time symmetric dimer
Li Ge
Parity-time (PT) symmetric dimers were introduced to highlight the unusual properties of non-Hermitian systems that are invariant after a combined parity and time reversal operatio…
