Controlled manipulation of matter-waves in atomic waveguiding structures

Neutral atoms cooled to temperatures near absolute zero can condense into a single quantum-mechanical state and start behaving as a single coherent wave of matter. This matter-wave can be trapped and guided by magnetic and optical potentials in a way similar to waveguiding of laser light. This project will develop novel concepts for waveguiding and manipulation of matter-waves in nonlinear couplers, beam splitters, periodic and disordered atom-guiding structures. This research will lay the theoretical foundations for the design of atomic waveguiding devices for fundamental studies of ultracold matter, as well as applications in high-precision measurements and sensing.
