Continuum of Bound States in a Non-Hermitian Model
Qiang Wang, Changyan Zhu, Xu Zheng +3
In a Hermitian system, bound states must have quantized energies, whereas extended states can form a continuum. We demonstrate how this principle fails for non-Hermitian systems, b…

Amplification of quantum signals by the non-Hermitian skin effect
Qiang Wang, Changyan Zhu, You Wang +2
The non-Hermitian skin effect (NHSE) is a phenomenon whereby certain non-Hermitian lattice Hamiltonians, particularly those with nonreciprocal couplings, can host an extensive numb…

A new quantum theory of gravity in the framework of general relativity
Chang-Yu Zhu, Heng Fan
Observed physical phenomena can be described well by quantum mechanics or general relativity. People may try to find an unified fundamental theory which mainly aims to merge gravit…
