Dynamics of exciton formation in planar nanostructures under the action of a quantum electromagnetic field under nonlinearity conditions

Abstract: The features of exciton formation in planar nanostructures under the action of a nonclassical field under the conditions of Kerr phase modulation are analyzed. Excitations of various exciton channels are enhanced or suppressed depending on the nonlinearity magnitude in the system. The possibility of controlling different excitation channels by varying the frequency detuning of the field relative to the resonant transition is demonstrated, and an analytical formula for determining its optimal value is found. The effect of amplification of even excitation channels has been detected, which is caused by correlations of photons under the action of a field in a state of two-mode squeezed vacuum.
