abstract

  • 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.
