Dynamical detection of topological charges
Long Zhang, Lin Zhang, Xiong-Jun Liu
We propose a generic scheme to characterize topological phases via detecting topological charges by quench dynamics. A topological charge is defined as the chirality of a monopole…
Observation of nodal-line semimetal with ultracold fermions in an optical lattice
Bo Song, Chengdong He, Sen Niu +4
Observation of topological phases beyond two-dimension (2D) has been an open challenge for ultracold atoms. Here, we realize for the first time a 3D spin-orbit coupled nodal-line s…
Spin-orbit coupling and topological phases for ultracold atoms
Long Zhang, Xiong-Jun Liu
Cold atoms with laser-induced spin-orbit (SO) interactions provide promising platforms to explore novel quantum physics, in particular the exotic topological phases, beyond natural…
Dynamical classification of topological quantum phases
Lin Zhang, Long Zhang, Sen Niu +1
Topological phase of matter is now a mainstream of research in condensed matter physics, of which the classification, synthesis, and detection of topological states have brought ex…
