Superconducting current and proximity effect in ABA and ABC multilayer graphene Josephson junctions
W. A. Munoz, L. Covaci, F. M. Peeters
Using a numerical tight-binding approach based on the Chebyshev-Bogoliubov-de Gennes method we describe Josephson junctions made of multilayer graphene contacted by top superconduc…
Adatoms and Anderson localization in graphene
Jose H. Garcia, Bruno Uchoa, Lucian Covaci +1
We address the nature of the disordered state that results from the adsorption of adatoms in graphene. For adatoms that sit at the center of the honeycomb plaquette, as in the case…
Resonant valley filtering of massive Dirac electrons
D. Moldovan, M. Ramezani Masir, L. Covaci +1
Electrons in graphene, in addition to their spin, have two pseudospin degrees of freedom: sublattice and valley pseudospin. Valleytronics uses the valley degree of freedom as a car…
Tight-binding description of intrinsic superconducting correlations in multilayer graphene
W. A. Munoz, L. Covaci, F. M. Peeters
Using highly efficient GPU-based simulations of the tight-binding Bogoliubov-de Gennes equations we solve self-consistently for the pair correlation in rhombohedral (ABC) and Berna…
Vortex states in nanoscale superconducting squares: the influence of quantum confinement
L. -F. Zhang, L. Covaci, M. V. Milošević +2
Bogoliubov-de Gennes theory is used to investigate the effect of the size of a superconducting square on the vortex states in the quantum confinement regime. When the superconducti…
