Irradiated Coherent States in Magnetoresistance of 2D Electron Systems

Herein, a novel theoretical approach on the microwave‐induced resistance oscillations based on the coherent states of the quantum harmonic oscillator is reported. Within the theoretical model of microwave‐induced electron orbits, the coherent state expression for the quantum harmonic oscillator under a time‐dependent force (radiation) is calculated. Thus, it is found that the principle of minimum uncertainty of coherent states, involving time and energy, is the main responsible of photo‐oscillations and zero‐resistance states. Thus, essential experimental results of this remarkable effect are shed light (and explained) on. The origin of photo‐oscillations, their position with respect to the magnetic field, and their periodicity can be distinguished.
