Peculiar Nature of Snake States in Graphene
P. Rakyta, L. Oroszlany, A. Kormanyos +2
We study the dynamics of the electrons in a non-uniform magnetic field applied perpendicular to a graphene sheet in the low energy limit when the excitation states can be described…
Caustics due to Negative Refractive Index in Circular Graphene p-n Junctions
Jozsef Cserti, Andras Palyi, Csaba Peterfalvi
We show that the wavefunctions form caustics in circular graphene p-n junctions which in the framework of geometrical optics can be interpreted with negative refractive index.
Role of the trigonal warping on the minimal conductivity of bilayer graphene
J. Cserti, A. Csordás, Gy. Dávid
Using a reformulated Kubo formula we calculate the zero-energy minimal conductivity of bilayer graphene taking into account the small but finite trigonal warping. We find that the…
Magnetic focusing in normal-superconductor hybrid systems: a semiclassical analysis
P. Rakyta, A. Kormanyos, Z. Kaufmann +1
We study a transverse electron-hole focusing effect in a normal-superconductor system. The spectrum of the quasiparticles is calculated both quantum mechanically and in semiclassic…
Skew scattering due to intrinsic spin-orbit coupling in a two-dimensional electron gas
Andras Palyi, Jozsef Cserti
We present the generalization of the two-dimensional quantum scattering formalism to systems with Rashba spin-orbit coupling. Using symmetry considerations, we show that the differ…
Nonthermal broadening in the conductance of double quantum dot structures
Laszlo Oroszlany, Andor Kormanyos, Janos Koltai +2
We study the transport properties of a double quantum dot (DQD) molecule at zero and at finite temperature. The properties of the zero temperature conductance depends on whether th…
