Synthetic Topological Vacua of Yang-Mills Fields in Bose-Einstein Condensates
Jia-Zhen Li, Cong-Jun Zou, Yan-Xiong Du +7
Topological vacua are a family of degenerate ground states of Yang-Mills fields with zero field strength but nontrivial topological structures. They play a fundamental role in part…
Topological quantum matter with cold atoms
Dan-Wei Zhang, Yan-Qing Zhu, Y. X. Zhao +2
This is an introductory review of the physics of topological quantum matter with cold atoms. Topological quantum phases, originally discovered and investigated in condensed matter…
Emergent pseudospin-1 Maxwell fermions with a threefold degeneracy in optical lattices
Yan-Qing Zhu, Dan-Wei Zhang, Hui Yan +2
The discovery of relativistic spin-1/2 fermions such as Dirac and Weyl fermions in condensed-matter or artificial systems opens a new era in modern physics. An interesting but rare…
Maxwell Quasiparticles Emerged in Optical Lattices
Yan-Qing Zhu, Dan-Wei Zhang, Hui Yan +2
We construct a two-dimensional tight-binding model of an optical lattice, where the low energy excitations should be described by the spin-1 Maxwell equations in the Hamiltonian fo…
Particle number fractionalization of a one-dimensional atomic Fermi gas with synthetic spin-orbit coupling
Dan-Wei Zhang, L. -B. Shao, Zheng-Yuan Xue +3
We propose an experimental scheme to simulate the fractionalization of particle number by using a one-dimensional spin-orbit coupled ultracold fermionic gas. The wanted spin-orbit…
Macroscopic Klein Tunneling in spin-orbit coupled Bose-Einstein Condensates
Dan-Wei Zhang, Zheng-Yuan Xue, Hui Yan +2
We propose an experimental scheme to detect macroscopic Klein tunneling with spin-orbit coupled Bose-Einstein condensates (BECs). We show that a nonlinear Dirac equation with tunab…
