Study of Higgs mode near quantum critical points

ORAL

Abstract

We present a study of Higgs excitation mode in different quantum theories in 2 space dimensions. $O(N)$ theory and $CP(N)$ theory near the quantum critical points will be discussed for zero and finite temperature. Electron systems with fermi surfaces will be studied under this framework.
