摘要：
In this talk, I will first brief review recent experiments on detecting Higgs mode in both cold atom and superconductor systems. In cold atom system, I will explain how the Lorentz symmetry emerges in the particle-hole symmetric point of the Bose-Hubbard model. I will then discuss the fate of Higgs mode away from the Lorentz symmetric point, using BEC-BCS crossover model as an example. Finally, I will point out that the Anderson-Higgs mechanism plays an important role in stabilizing a well-defined Higgs mode in superconductor.
