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…
Aharonov-Bohm effect for a valley-polarized current in graphene
A. Rycerz, C. W. J. Beenakker
This is a numerical study of the conductance of an Aharonov-Bohm interferometer in a tight-binding model of graphene. Two single-mode ballistic point contacts with zigzag edges are…
Splitting of Andreev levels in a Josephson junction by spin-orbit coupling
B. Béri, J. H. Bardarson, C. W. J. Beenakker
We consider the effect of spin-orbit coupling on the energy levels of a single-channel Josephson junction below the superconducting gap. We investigate quantitatively the level spl…
Aharonov-Bohm effect and broken valley-degeneracy in graphene rings
P. Recher, B. Trauzettel, A. Rycerz +3
We analyze theoretically the electronic properties of Aharonov-Bohm rings made of graphene. We show that the combined effect of the ring confinement and applied magnetic flux offer…
Reentrance effect in a graphene n-p-n junction coupled to a superconductor
A. Ossipov, M. Titov, C. W. J. Beenakker
We study the interplay of Klein tunneling (= interband tunneling) between n-doped and p-doped regions in graphene and Andreev reflection (= electron-hole conversion) at a supercond…
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…
