Beating of the oscillations in the transport coefficients of a one-dimensionally periodically modulated two-dimensional electron gas in the presence of spin-orbit interaction
X. F. Wang, P. Vasilopoulos, F. M. Peeters
Transport properties of a two-dimensional electron gas (2DEG) are studied in the presence of a perpendicular magnetic field , of a {\it weak} one-dimensional (1D) periodic poten…
Experimental Evidence for Giant Vortex States in a Mesoscopic Superconducting Disk
A. Kanda, B. J. Baelus, F. M. Peeters +2
Response of a mesoscopic superconducting disk to perpendicular magnetic fields is studied by using the multiple-small-tunnel-junction method, in which transport properties of sever…
Exact broken-symmetry states and Hartree-Fock solutions for quantum dots at high magnetic fields
B. Szafran, F. M. Peeters, S. Bednarek +1
Wigner molecules formed at high magnetic fields in circular and elliptic quantum dots are studied by exact diagonalization (ED) and unrestricted Hartree-Fock (UHF) methods with mul…
Power-law dependence of the angular momentum transition fields in few-electron quantum dots
E. Anisimovas, A. Matulis, M. B. Tavernier +1
We show that the critical magnetic fields at which a few-electron quantum dot undergoes transitions between successive values of its angular momentum (M), for large M values follow…
Currents in a many-particle parabolic quantum dot under a strong magnetic field
E. Anisimovas, A. Matulis, F. M. Peeters
Currents in a few-electron parabolic quantum dot placed into a perpendicular magnetic field are considered. We show that traditional ways of investigating the Wigner crystallizatio…
Spin-dependent (magneto)transport through a ring due to spin-orbit interaction
B. Molnar, F. M. Peeters, P. Vasilopoulos
Electron transport through a one-dimensional ring connected with two external leads, in the presence of spin-orbit interaction (SOI) of strength αand a perpendicular magnetic field…
