Many-body effects in the cyclotron resonance of a magnetic dot
Nga T. T. Nguyen, F. M. Peeters
Intraband cyclotron resonance (CR) transitions of a two-electron quantum dot containing a single magnetic ion is investigated for different Coulomb interaction strengths and differ…
Electrostatically confined Quantum Rings in bilayer Graphene
M. Zarenia, J. M. Pereira, F. M. Peeters +1
We propose a new system where electron and hole states are electrostatically confined into a quantum ring in bilayer graphene. These structures can be created by tuning the gap of…
Magnetic Kronig-Penney model for Dirac electrons in single-layer graphene
M. Ramezani Masir, P. Vasilopoulos, F. M. Peeters
The properties of Dirac electrons in a magnetic superlattice (SL) on graphene consisting of very high and thin (delta-function) barriers are investigated. We obtain the energy spec…
Quasi-bound states of Schrodinger and Dirac electrons in magnetic quantum dot
M. Ramezani Masir, A. Matulis, F. M. Peeters
The properties of a two-dimensional electron are investigated in the presence of a circular step magnetic field profile. Both electrons with parabolic dispersion as well as Dirac e…
