Zener quantum dot spin filter in a carbon nanotube
D. Gunlycke, J. H. Jefferson, S. W. D. Bailey +3
We predict and analyze a novel spin filter in semiconducting carbon nanotubes. By using local electrostatic gates, the conduction and valence bands can be modulated to form a doubl…
Effective Random Matrix Theory description of chaotic Andreev billiards
A. Kormányos, Z. Kaufmann, C. J. Lambert +1
An effective random matrix theory description is developed for the universal gap fluctuations and the ensemble averaged density of states of chaotic Andreev billiards for finite Eh…
Andreev bound states for superconducting-ferromagnetic box
J. Cserti, J. Koltai, C. J. Lambert
Within the microscopic Bogoliubov--de Gennes (BdG) formalism an exact quantization condition for Andreev bound states of the ferromagnetic-superconducting hybrid systems of box geo…
A logarithmic contribution to the density of states of rectangular Andreev billiards
A. Kormányos, Z. Kaufmann, J. Cserti +1
We demonstrate that the exact quantum mechanical calculations are in good agreement with the semiclassical predictions for rectangular Andreev billiards and therefore for a large n…
Material-specific spin filtering in ferromagnet/superconductor ballistic nanojunctions
F. Taddei, S. Sanvito, C. J. Lambert
We study spin-dependent electronic transport across ferromagnet/superconductor ballistic junctions modeled using tight-binding Hamiltonians with s, p and d orbitals and material-sp…
Lévy flights in quantum transport in quasi-ballistic wires
M. Leadbeater, V. I. Falko, C. J. Lambert
Conductance fluctuations, localization and statistics of Lyapunov exponents are studied numerically in pure metallic wires with rough boundaries (quasi-ballistic wires). We find th…
