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…
Synthetic Landau levels and spinor vortex matter on Haldane spherical surface with magnetic monopole
Xiang-Fa Zhou, Congjun Wu, Guang-Can Guo +3
We present a flexible scheme to realize exact flat Landau levels on curved spherical geometry in a system of spinful cold atoms. This is achieved by Floquet engineering of a magnet…
Majorana edge state in a number-conserving Fermi gas with tunable p-wave interaction
X. Y. Yin, Tin-Lun Ho, Xiaoling Cui
The remarkable properties and potential applications of Majorana fermions have led to considerable efforts in recent years to realize topological matters that host these excitation…
Superfluidity of identical fermions in an optical lattice: atoms and polar molecules
A. K. Fedorov, V. I. Yudson, G. V. Shlyapnikov
In this work, we discuss the emergence of -wave superfluids of identical fermions in 2D lattices. The optical lattice potential manifests itself in an interplay between an incre…
Phase transitions in quasi-one dimensional system with unconventional superconductivity
Andrzej Ptok, Agnieszka Cichy, Karen Rodríguez +1
The paper is devoted to a study of superconducting properties of population-imbalanced fermionic mixtures in quasi-one dimensional optical lattices. The system can be effectively d…
Topological Supersolidity of Dipolar Fermi Gases in a Spin-Dependent Optical Lattice
Huan-Yu Wang, Zhen Zheng, Lin Zhuang +1
We investigate topological supersolidity of dipolar Fermi gases in a spin-dependent 2D optical lattice. Numerical results show that the topological supersolid states can be synthes…
