Geometry and superfluidity of the flat band in a non-Hermitian optical lattice
Peng He, Hai-Tao Ding, Shi-Liang Zhu
We propose an ultracold-atom setting where a fermionic superfluidity with attractive s-wave interaction is uploaded in a non-Hermitian Lieb optical lattice. The existence of a real…
Double exceptional links in a three-dimensional dissipative cold atomic gas
Peng He, Jia-Hao Fu, Dan-Wei Zhang +1
We explore the topological properties of non-Hermitian nodal-link semimetals with dissipative cold atoms in a three-dimensional optical lattice. We construct a two-band continuum m…
Floquet engineering and simulating exceptional rings with a quantum spin system
Peng He, Ze-Hao Huang
Time-periodic driving in the form of coherent radiation provides powerful tool for the manipulation of topological materials or synthetic quantum matter. In this paper we propose a…
Nonlinear Bloch-Zener oscillations for Bose-Einstein condensates in a Lieb optical lattice
Peng He, Zhi Li
We investigate Bloch-Zener oscillations and mean-field Bloch bands of a Bose-Einstein condensate (BEC) in a Lieb optical lattice. We find that the atomic interaction will break the…
Simulating the Klein tunneling of pseudospin-one Maxwell particles with trapped ions
Peng He, Xin Shen, Dan-Wei Zhang +1
We propose an experimental scheme to simulate and observe the Klein tunneling of relativistic Maxwell particles with trapped ions. We explore the scattering dynamics of the pseudos…
Universal low energy physics in one-dimensional multicompnent Fermi gases with a strongly repulsive -function interaction
Yuzhu Jiang, Peng He, Xi-Wen Guan
It was shown [Chin. Phys. Lett. 28, 020503 (2011)] that at zero temperature the ground state of the one-dimensional (1D) -component Fermi gas coincides with that of the spinless…
