Beom Jun Kim (Sungkyunkwan Univ.) We study resonance behavior of the infinite-range quantum and classical kinetic Ising model. For the quantum system, numerical integration of the time-dependent Schrodinger equation is performed, and for the classical case the master equation approach with the Glauber dynamics is applied. It is revealed that for both quantum and classical models, two resonance peaks occur below and above the phase transition. The origin of the double peaks is explained from the time-scale matching condition. Extension to other systems such as the q-state clock model is also be discussed. |
