Tunable boson-assisted finite-range interaction and engineering Majorana corner modes in optical lattices
Yu-Biao Wu, Zhen Zheng, Xiang-Gang Qiu +4
Nonlocal interaction between ultracold atoms trapped in optical lattices can give rise to interesting quantum many-body phenomena. However, its realization usually demands unconven…
Multiorder topological superfluid phase transitions in a two-dimensional optical superlattice
Yu-Biao Wu, Guang-Can Guo, Zhen Zheng +1
Higher-order topological superfluids have gapped bulk and symmetry-protected Majorana zero modes with various localizations. Motivated by recent advances, we present a proposal for…
Effective Hamiltonian with tunable mixed pairing in driven optical lattices
Yu-Biao Wu, Guang-Can Guo, Zhen Zheng +1
Mixed pairing in ultracold Fermi gases can give rise to interesting many-body phases, such as topological nontrivial superfluids that support Majorana zero modes (MZMs) with variou…
Field-induced topological pair-density wave states in a multilayer optical lattice
Zhen-Fei Zheng, Guang-Can Guo, Han Pu +1
We study the superfluid phases of a Fermi gas in a multilayer optical lattice system in the presence of out-of-plane Zeeman field, as well as spin-orbit (SO) coupling. We show that…
Synthetic topological Kondo insulator in a pumped optical cavity
Zhen Zheng, Xu-Bo Zou, Guang-Can Guo
Motivated by experimental advances on ultracold atoms coupled to a pumped optical cavity, we propose a scheme for synthesizing and observing the Kondo insulator in Fermi gases trap…
Fulde-Ferrell superfluids in spinless ultracold Fermi gases
Zhen-Fei Zheng, Guang-Can Guo, Zhen Zheng +1
The Fulde-Ferrell (FF) superfluid phase, in which fermions form finite-momentum Cooper pairings, is well studied in spin-singlet superfluids in past decades. Different from previou…
