Topological Invariant for Multi-Band Non-hermitian Systems with Chiral Symmetry
ChunChi Liu, LiuHao Li, Jin An
Topology plays an important role in non-hermitian systems. How to characterize a non-hermitian topological system under open-boundary conditions(OBCs) is a challenging problem. A o…
Connections between the Open-boundary Spectrum and Generalized Brillouin Zone in Non-Hermitian Systems
Deguang Wu, Jiao Xie, Yao Zhou +1
Periodic-boundary spectrum, open-boundary spectrum, as well as the generalized Brillouin zone (GBZ) are three essential properties of a one-dimensional non-Hermitian system. In thi…
Spin-orbit coupled spin-1 Bose-Einstein condensate flow past an obstacle in the presence of a Zeeman field
Qing-Li Zhu, Lihua Pan, Jin An
We study the dynamics of a Rashba spin-orbit coupled spin-1 ferromagnetic Bose-Einstein condensate under a linear Zeeman magnetic field(ZF) disturbed by a moving obstacle. The Bogo…
Inter-orbital p- and d-wave pairings between and orbitals in SrRuO
Weipeng Chen, Jin An
We study the pairing symmetry of SrRuO through the group-theoretical approach. We emphasize the role of pairing interaction between the quasi-one-dimensional(Q1D) $d_{xz/yz…
Spin and charge transport in topological nodal-line semimetals
Yao Zhou, Feng Xiong, Weipeng Chen +1
We study transport properties of topological Weyl nodal-line semimetals(NLSs). Starting from a minimal lattice model with a single nodal loop, and by focusing on a normal-metal-NLS…
Topological Ising pairing states in monolayer and trilayer TaS
Weipeng Chen, Jin An
We study the possibility of topological superconductivity in the noncentrosymmetric monolayer and trilayer TaS with out-of-plane mirror symmetry. A gapless time-reversal invari…
