Non-Hermitian interferometer: Unidirectional amplification without distortion
C. Li, L. Jin, Z. Song
A non-Hermitian interferometer can realize asymmetric transmission in the presence of imaginary potential and magnetic flux. Here, we propose a non-Hermitian dimer with an unequal…

Quantum phase transition induced by real-space topology
C. Li, G. Zhang, S. Lin +1
A quantum phase transition (QPT), including both topological and symmetry breaking types, is usually induced by the change of global parameters, such as external fields or global c…

Conventional quantum phase transition driven by complex parameter in non-Hermitian PT-symmetric Ising model
C. Li, G. Zhang, X. Z. Zhang +1
A conventional quantum phase transition (QPT) can be accessed by varying a real parameter at absolute zero temperature. Motivated by the discovery of the pseudo-Hermiticity of non-…
