Controllable Hartman effect by vortex beam in a one dimensional photonic crystal doped by graphene quantum dots
The Hartman effect is studied in a one dimensional photonic crystal doped with graphene quantum dots. It is shown that the Hartman effect can be switched from negative to positive by increasing the Rabi-frequency of the controlling field and also by manipulating the relative phase of the applied fie...
