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…
Collective excitations of trapped Fermi or Bose gases
A. Csordas, Z. Adam
A new method is developed to calculate all excitations of trapped gases using hydrodynamics at zero temperature for any equation of state and for any trapping potential. I…
Rashba billiards
András Csordás, József Cserti, András Pályi +1
We study the energy levels of non-interacting electrons confined to move in two-dimensional billiard regions and having a spin-dependent dynamics due to a finite Rashba spin splitt…
Cluster states of Fermions in the single l-shell model
Andras Csordas, Eva Szoke, Peter Szepfalusy
The paper concerns the ground state structure of the partly filled l-shell of a fermionic gas of atoms of spin s in a spherically symmetric spin independent trap potential. At part…
Clustering of Fermi particles with arbitrary spin
Andras Csordas, Peter Szepfalusy, Eva Szoke
A single l-shell model is investigated for a system of fermions of spin s and an attractive s-wave, spin channel independent, interaction. The spectra and eigenvectors are determin…
Exact quantum state for N=1 supergravity
Andras Csordas, Robert Graham
For N=1 supergravity in 3+1 dimensions we determine the graded algebra of the quantized Lorentz generators, supersymmetry generators, and diffeo-morphism and Hamiltonian generators…
