Exact propagator for an electron in a quadratic saddle-point potential and a magnetic field
-
Abstract
We study the propagator for an electron moving in a two-dimensional (2D) quadratic saddle-point potential, in the presence of a perpendicular uniform magnetic field. A closed-form expression for the propagator is derived using the Feynmann path integrals. -
