Gaussian eigenstate pinning in non-Hermitian quantum mechanics
Qi-Bo Zeng, Rong Lü
We study a one-dimensional system subjected to a linearly varying imaginary vector potential, which is described by the single-particle continuous Schrödinger equation and is analy…

Real spectra and phase transition of skin effect in nonreciprocal systems
Qi-Bo Zeng, Rong Lü
We study the one-dimensional nonreciprocal lattices with real nearest neighboring hopping and find that the energy spectra under open boundary conditions can be entirely real or im…

Transport through a non-Hermitian Aharonov-Bohm ring with physical gain and loss
Qi-Bo Zeng, Shu Chen, Rong Lü
We investigate a non-Hermitian Aharonov-Bohm (AB) ring system with a quantum dot (QD) embedded in each of its two arms. The energy levels of the QDs are complex in order to take in…
