Hartman effect and spin precession in graphene
R. A. Sepkhanov, M. V. Medvedyeva, C. W. J. Beenakker
Spin precession has been used to measure the transmission time τover a distance L in a graphene sheet. Since conduction electrons in graphene have an energy-independent velocity v,…
Quantum Goos-Hanchen effect in graphene
C. W. J. Beenakker, R. A. Sepkhanov, A. R. Akhmerov +1
The Goos-Hanchen (GH) effect is an interference effect on total internal reflection at an interface, resulting in a shift sigma of the reflected beam along the interface. We show t…
Extinction of coherent backscattering by a disordered photonic crystal with a Dirac spectrum
R. A. Sepkhanov, A. Ossipov, C. W. J. Beenakker
Photonic crystals with a two-dimensional triangular lattice have a conical singularity in the spectrum. Close to this so-called Dirac point, Maxwell's equations reduce to the Dirac…
How to detect the pseudospin-1/2 Berry phase in a photonic crystal with a Dirac spectrum
R. A. Sepkhanov, Johan Nilsson, C. W. J. Beenakker
We propose a method to detect the geometric phase produced by the Dirac-type band structure of a triangular-lattice photonic crystal. The spectrum is known to have a conical singul…
Numerical test of the theory of pseudo-diffusive transmission at the Dirac point of a photonic band structure
R. A. Sepkhanov, C. W. J. Beenakker
It has recently been predicted that a conical singularity (= Dirac point) in the band structure of a photonic crystal produces an unusual 1/L scaling of the photon flux transmitted…
Extremal transmission at the Dirac point of a photonic band structure
R. A. Sepkhanov, Ya. B. Bazaliy, C. W. J. Beenakker
We calculate the effect of a Dirac point (a conical singularity in the band structure) on the transmission of monochromatic radiation through a photonic crystal. The transmission a…
