Berry phase for a potential well transported in a homogeneous magnetic field (2000)
Exner, Pavel, Geyler, Vladimir A.
We consider a two-dimensional particle of charge $e$ interacting with a homogeneous magnetic field perpendicular to the plane and a potential well which is transported along a closed loop in the...
Berry phase in magnetic systems with point perturbations (1999)
Exner, Pavel, Geyler, Vladimir A.
We study a two-dimensional charged particle interacting with a magnetic field, in general non-homogeneous, perpendicular to the plane, a confining potential, and a point interaction. If the latter...
