Topological Gapless Matters in Three-dimensional Ultracold Atomic Gases
Yong Xu
Three-dimensional topological gapless matters with gapless degeneracies protected by a topological invariant defined over a closed manifold in momentum space have attracted conside…
Scheme to Equilibrate the Quantized Hall Response of Topological Systems from Coherent Dynamics
Yong Xu, Ying Hu
Two-dimensional topologically distinct insulators are separated by topological gapless points, which exist as Weyl points in three-dimensional momentum space. Slowly varying parame…
Dynamical Weyl Points and 4D Nodal Rings in Cold Atomic Gases
Yan-Bin Yang, L. -M. Duan, Yong Xu
Controllability of ultracold atomic gases has reached an unprecedented level, allowing for experimental realization of the long-sought-after Thouless pump, which can be interpreted…
Weyl Exceptional Rings in a Three-Dimensional Dissipative Cold Atomic Gas
Yong Xu, Sheng-Tao Wang, L. -M. Duan
Three-dimensional topological Weyl semimetals can generally support a zero-dimensional Weyl point characterized by a quantized Chern number or a one-dimensional Weyl nodal ring (or…
Type-II Weyl Points in Three-Dimensional Cold Atom Optical Lattices
Yong Xu, L. -M. Duan
Topological Lifshitz phase transition characterizes an abrupt change of the topology of the Fermi surface through a continuous deformation of parameters. Recently, Lifshitz transit…
