Abstract: Goos-Hänchen (GH) shifts in the reflected and transmitted light have been discussed in a cavity with four-level quantum system. It is realized that the refraction index of intracavity medium can be negative by manipulating the… read more here.

DOI: 10.1016/j.physe.2020.114010
Abstract: Abstract Using the energy spectrum of graphene with spatially modulated potential, we study the Goos-Hanshen shifts near extra Dirac points located at finite energy ϵ = mπ, with m integer. On both sides of such points, we… read more here.
