Phase control of the Pancharatnam phase

Résumé

We propose a method to control the atomic dynamics in the presence of electromagnetic fields. Instead of measuring the population dynamics, we focus on the possibility of controlling the Pancharatnam phase. For a two-level system we find that this phase can be optically induced and controlled by the phase shift. More importantly, the nonlinear interaction between the atom and the field leads to an enhanced sensitivity for the control of the atomic phase evolution and system dynamics.
