Abstract
By utilizing the hybrid recursive Green's function method, we study th e exact numerical photoconductance of quantum point contacts and compa re it with features obtained in the analytic adiabatic regime. We find that the main features of the photoconductance oscillations are prese nt, but with quantum corrections. These corrections are mainly due to deviations from the semiclassical description of wave functions. Nonad iabatic corrections enhance the photoconductance oscillations.
