Seminar

The Magnus expansion in the adiabatic picture

Casas, F (Jaume)
Tuesday 03 July 2007, 15:30-16:00

Seminar Room 1, Newton Institute

Abstract

In this talk we review the main aspects of the Magnus expansion for treating time-dependent systems evolving in a near-adiabatic regime. We discuss its applicability and the convergence domain. We will show, in particular, how this procedure alllows us to obtain very accurate approximations to the transition probability for time-dependent two-state quantum systems even far from the adiabatic limit.
