Interaction induced topological Bogoliubov excitations in a spin-orbit coupled Bose-Einstein condensate
Guan-Hua Huang, Guang-Quan Luo, Zhigang Wu +1
We study topologically non-trivial excitations of a weakly interacting, spin-orbit coupled Bose-Einstein condensate in a two-dimensional square optical lattice, a system recently r…
Detecting chiral pairing and topological superfluidity using circular dichroism
J. M. Midtgaard, Zhigang Wu, N. Goldman +1
Realising and probing topological superfluids is a key goal for fundamental science, with exciting technological promises. Here, we show that chiral pairing in a two-dim…
Many-Body Echo
Yang-Yang Chen, Pengfei Zhang, Wei Zheng +2
In this letter we propose a protocol to reverse a quantum many-body dynamical process. We name it "many-body echo" because the underlying physics is closely related to the spin ech…
Vortex end Majorana zero modes in superconducting Dirac and Weyl semimetals
Zhongbo Yan, Zhigang Wu, Wen Huang
Time-reversal invariant (TRI) Dirac and Weyl semimetals in three dimensions (3D) can host open Fermi arcs and spin-momentum locking Fermi loops on the surfaces. We find that when t…
Constraints on the energy spectrum of non-Hermitian models in open environments
Jonatan Melkær Midtgaard, Zhigang Wu, Yu Chen
Motivated by recent progress on non-Hermitian topological band theories, we study the energy spectrum of a generic two-band non-Hermitian Hamiltonian. We prove rigorously that the…
Higher-order topological superconductivity: possible realization in Fermi gases and SrRuO
Zhigang Wu, Zhongbo Yan, Wen Huang
We propose to realize second-order topological superconductivity in bilayer spin-polarized Fermi gas superfluids. We focus on systems with intralayer chiral -wave pairing and wi…
