Confinement-deconfinement transitions of two-dimensional Dirac particles

Date: 
Tuesday 31st July 2012 - 16:00 to 16:45
Venue: 
INI Seminar Room 1
Abstract: 
It is well known that , as opposed to the non-relativistic case, particles described by the Dirac operator can not be confined through electric potential walls. However, one can produce a strongly confined system by adding a magnetic field growing at infinity. In this talk I will present some results describing confinement-deconfinement transitions of two-dimensional Dirac particles obtained by modulating the electro-magnetic field at infinity.

This is joint work with Josef Mehringer.
