Normal ordering solution to quantum dissipation and its induced decoherence
Abstract
We implement the normal ordering technique to study the quantum dissipation of a single mode harmonic oscillator system. The dynamic evolution of the system is investigated for a reasonable initial state by solving the Schr\"odinger equation directly through the normal ordering technique. The decoherence process of the system for the cases T=0K and T≠0K is investigated as an application.
