简介: |
We discuss dynamics near quantum critical points at which the ground state is infinitely degenerate. It is shown that at the very neighborhood of a critical point, a semiclassical approach may be valid in the study of the dynamics of the system. Applications are given in the computation of the so-called quantum Loschmidt echo, or survival probability in several models. |
