Quench dynamics of Hopf insulators
Haiping Hu, Chao Yang, Erhai Zhao
Hopf insulators are exotic topological states of matter outside the standard ten-fold way classification based on discrete symmetries. Its topology is captured by an integer invari…
Topological phases in pseudospin-1 Fermi gases with two-dimensional spin-orbit coupling
Junpeng Hou, Haiping Hu, Chuanwei Zhang
The recent experimental realization of spin-orbit (SO) coupling for ultracold bosons and fermions opens an exciting avenue for engineering quantum matter that may be challenging to…
Spin-1 Topological Monopoles in Parameter Space of Ultracold Atoms
Haiping Hu, Chuanwei Zhang
Magnetic monopole, a hypothetical elementary particle with isolated magnetic pole, is crucial for the quantization of electric charge. In recent years, analogues of magnetic monopo…
Topological Mott Insulator with Bosonic Edge Modes in 1D Fermionic Superlattices
Haiping Hu, Shu Chen, Tian-Sheng Zeng +1
We investigate topological phase transitions driven by interaction and identify a novel topological Mott insulator state in one-dimensional fermionic optical superlattices through…
Majorana Doublets, Flat Bands, and Dirac Nodes in s-Wave Superfluids
Haiping Hu, Fan Zhang, Chuanwei Zhang
Topological superfluids protected by mirror and time-reversal symmetries are exotic states of matter possessing Majorana Kramers pairs (MKPs), yet their realizations have long been…
Superfluid-quasicrystal in a Bose-Einstein condensate
Junpeng Hou, Haiping Hu, Kuei Sun +1
Quasicrystal is a class of ordered structures defying conventional classification of solid crystals and may carry classically forbidden (e.g., 5-fold) rotational symmetries. In vie…
Exact ordering of energy levels for one-dimensional interacting Fermi gases with symmetry
Lei Pan, Yanxia Liu, Haiping Hu +2
Based on the exact solution of one-dimensional Fermi gas systems with symmetry in a hard wall, we demonstrate that we are able to sort the ordering of the lowest energy eig…
Strongly interacting one-dimensional quantum gas mixtures with weak p-wave interactions
Haiping Hu, Lei Pan, Shu Chen
We study one-dimensional strongly interacting quantum gas mixtures, including both the Bose-Fermi and spin-1/2 Fermi-Fermi mixtures, with weak p-wave interactions between intra-com…
Strongly interacting Bose-Fermi mixtures in one dimension
Haiping Hu, Liming Guan, Shu Chen
We study one-dimensional strongly interacting Bose-Fermi mixtures by both the exact Bethe-ansatz method and variational perturbation theory within the degenerate ground state subsp…
Mapping trapped atomic gas with spin-orbit coupling to quantum Rabi-like model
Haiping Hu, Shu Chen
We construct a connection of the ultracold atomic system in a harmonic trap with Raman-induced spin-orbit coupling to the quantum Rabi-like model. By mapping the trapped atomic sys…
Ferromagnetic to antiferromagnetic transition of one-dimensional spinor Bose gases with spin-orbit coupling
Xing Chen, Haiping Hu, Yuzhu Jiang +1
We have analytically solved one-dimensional interacting two-component bosonic gases with spin-orbit (SO) coupling by the Bethe-ansatz method. Through a gauge transformation, the ef…
