Classical limit of an induced harmonic oscillation with radiation damping
Tadashi Toyoda, K. Wildermuth · Physical Review A · 1983
The previously proposed method to obtain classical limits of quantized fields using von Neumann - lattice coherent states as basis states for the projection form of the Schr\"odinger equation is modified in order to take into account the reaction of the radiation field to the charge in a compact manner. The modification is based on the work of Glauber on the time evolution of coherent states. To illustrate the method, a charged harmonic oscillator with and without initial external electromagnetic field is investigated.
