Quantum-classical correspondence in the wavefunctions of Andreev billiards
A. Kormanyos, Z. Kaufmann, J. Cserti +1
We present a classical and quantum mechanical study of an Andreev billiard with a chaotic normal dot. We demonstrate that in general the classical dynamics of these normal-supercon…
Bound states in Andreev billiards with soft walls
F. Libisch, S. Rotter, J. Burgdoerfer +2
The energy spectrum and the eigenstates of a rectangular quantum dot containing soft potential walls in contact with a superconductor are calculated by solving the Bogoliubov-de Ge…
Electronic and spin properties of Rashba billiards
József Cserti, András Csordás, Ulrich Zülicke
Ballistic electrons confined to a billiard and subject to spin--orbit coupling of the Rashba type are investigated, using both approximate semiclassical and exact quantum--mechanic…
Quantum and semiclassical study of magnetic anti-dots
B. Kocsis, G. Palla, J. Cserti
We study the energy level structure of two-dimensional charged particles in inhomogeneous magnetic fields. In particular, for magnetic anti-dots the magnetic field is zero inside t…
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…
