Large spatial Goos-Hänchen shifts from quasicrystals with graphene
Results in Physics, 2020 We investigate the spatial Goos-Hänchen (GH) shift of reflected beam from quasicrystals composed of Fibonacci dielectrics and graphene. The quasicrystals are composed of two symmetrical Fibonacci dielectrics and graphene is embedded in the center of the ...

Negative group delay of reflected Weyl quasiparticles
New Journal of Physics, 2021 When an electron is incident from a Weyl material to an insulator and totally reflected, it suffers a reflection group delay and a reflection shift (Goos–Hänchen and/or Imbert–Fedorov shifts). We found the group delay is negative for half of the incident

Goos–Hänchen and Imbert–Fedorov shifts from a quantum-mechanical perspective
New Journal of Physics, 2013 We study the classical optics effects known as Goos–Hänchen and Imbert–Fedorov shifts, occurring when reflecting a bounded light beam from a planar surface, by using a quantum-mechanical formalism.
