Berry curvature inside parity-time-symmetry protected exceptional surface
P. Wang, L. Jin, Z. Song
A three-dimensional non-Hermitian Hamiltonian with parity-time symmetry can exhibit a closed exceptional surface (EP surface) in momentum space, which is a non-Hermitian deformatio…

Visualizing Topology of Real-Energy Gapless Phase Arising from Exceptional Point
X. M. Yang, P. Wang, L. Jin +1
The discovery of novel topological phase advances our knowledge of nature and stimulates the development of applications. In non-Hermitian topological systems, the topology of band…

Su-Schrieffer-Heeger chain with one pair of PT-symmetric defects
L. Jin, P. Wang, Z. Song
The topologically nontrivial edge states induce PT transition in Su-Schrieffer-Heeger (SSH) chain with one pair of gain and loss at boundaries. In this study, we investigated a pai…
