Symmetry Protected and Topologically Protected Crossed Andreev Reflection
Yi-Ming Wu, Xiong-Jun Liu
Crossed Andreev reflection (CAR) is considered to probe the non-locality of the Majorana quasiparticles in topological superconductors. We propose here to study the CAR in multiban…
Realization of Two-Dimensional Spin-orbit Coupling for Bose-Einstein Condensates
Zhan Wu, Long Zhang, Wei Sun +7
Cold atoms with laser-induced spin-orbit (SO) interactions provide intriguing new platforms to explore novel quantum physics beyond natural conditions of solids. Recent experiments…
Chern Kondo Insulator in an Optical Lattice
Hua Chen, Xiong-Jun Liu, X. C. Xie
We propose to realize and observe Chern Kondo insulators in an optical superlattice with laser-assisted and orbital hybridization and synthetic gauge field, which can be en…
Topological superradiant state in Fermi gases with cavity induced spin-orbit coupling
Dongyang Yu, Jian-Song Pan, Xiong-Jun Liu +2
Coherently driven atomic gases inside optical cavities hold great promise for generating rich dynamics and exotic states of matter. It was shown recently that an exotic topological…
Non-Abelian Chiral Spin Liquid on the Kagome Lattice
Zheng-Xin Liu, Hong-Hao Tu, Ying-Hai Wu +4
We study spin liquid states on the kagome lattice constructed by Gutzwiller-projected superconductors. We show that the obtained spin liquids are either non-Abelia…
Symmetry Reduction and Boundary Modes for Fe-Chains on an s-wave Superconductor
Yu-Qin Chen, Yi-Ming Wu, Xiong-Jun Liu
We investigate the superconducting phase diagram and boundary modes for a quasi-1D system formed by three Fe-Chains on an s-wave superconductor, motivated by the recent Princeton e…
