Observing complementary Lucas sequences using non-Hermitian zero modes
Li Ge
The Lucas sequences are integers defined by a homogeneous recurrence relation. They include the well-known Fibonacci numbers, which appear abundantly in nature. The complementary L…

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…
