Wavepacket scattering on graphene edges in the presence of a (pseudo) magnetic field
D. R. da Costa, A. Chaves, G. A. Farias +2
The scattering of a Gaussian wavepacket in armchair and zigzag graphene edges is theoretically investigated by numerically solving the time dependent Schrödinger equation for the t…
Unconventional vortex states in nanoscale superconductors due to shape-induced resonances in the inhomogeneous Cooper-pair condensate
L. -F. Zhang, L. Covaci, M. V. Milošević +2
Vortex matter in mesoscopic superconductors is known to be strongly affected by the geometry of the sample. Here we show that in nanoscale superconductors with coherence length com…
Tight-binding study of bilayer graphene Josephson junctions
W. A. Muñoz, L. Covaci, F. M. Peeters
Using highly efficient simulations of the tight-binding Bogoliubov-de Gennes model we solved self-consistently for the pair correlation and the Josephson current in a Superconducti…
Field effect on surface states in a doped Mott-Insulator thin film
D. Nasr Esfahani, L. Covaci, F. M. Peeters
Surface effects of a doped thin film made of a strongly correlated material are investigated both in the absence and presence of a perpendicular electric field. We use an inhomogen…
Partially unzipped carbon nanotubes as magnetic field sensors
S. Costamagna, A. Schulz, L. Covaci +1
The conductance, , through graphene nanoribbons (GNR) connected to a partially unzipped carbon nanotube (CNT) is studied in the presence of an external magnetic field applied…
Nano-engineered non-uniform strain in graphene
M. Neek-Amal, L. Covaci, F. M. Peeters
Recent experiments showed that non-uniform strain can be produced by depositing graphene over pillars. We employed atomistic calculations to study the non-uniform strain and the in…
