Phase Evolution in Spatial Dark States

Abstract

Adiabatic techniques using multi-level systems have recently been generalised from the optical case to settings in atom optics, solid state and even classical electrodynamics. The most well known example of these is the so called STIRAP process, which allows transfer of a particle between different states with large fidelity. Here we generalise and examine this process for an atomic centre-of-mass state with a non-trivial phase distribution and show that even though dark state dynamics can be achieved for the atomic density, the phase dynamics will still have to be considered as a dynamical process. In particular we show that the combination of adiabatic and non-adiabatic behaviour can be used to engineer phase superposition states.
