摘要：
By utilizing the hybrid recursive Green's function method, we study the exact numerical photoconductance of quantum point contacts and compare it with features obtained in the analytic adiabatic regime. We find that the main features of the photoconductance oscillations are present, but with quantum corrections. These corrections are mainly due to deviations from the semiclassical description of wave functions. Nonadiabatic corrections enhance the photoconductance oscillations.
