Simulation of nodal-line semimetal in amplitude-shaken optical lattices

27 Aug 2020 Zhou Tanji Yu Zhongcheng Li Zhihan Chen Xuzong Zhou Xiaoji

With topologcial semimetal developing, semimetal with nodal-line ring comes into people's vision as a powerful candidate for practical application of topological devices. We propose a method using ultracold atoms in two-dimensional amplitude-shaken bipartite hexagonal optical lattice to simulate nodal-line semimetal, which can be achieved in experiment by attaching one triangular optical lattice to a hexangonal optical lattice and periodically modulating the intensity and position of the triangular lattice...
