Description

My application concerns three theoretical projects, all relating to ongoing experiments with cold atoms: 1) Antihydrogen: I work together with the ALPHA experiment at CERN, where cold antihydrogen is created. The goal is to trap antihydrogen, and use spectroscopy to test fundamental matter-antimatter symmetries, primarily the CPT theorem. To do this the antiatoms must be cold and magnetically trapped. I work on simulations of antihydrogen formation from antiprotons injected into a trapped positron plasma. A different simulation code will be developed for trapping and deexcitation of stabilized antihydrogen, including chaotic internal dynamics. I will also continue to work on ultracold antihydrogen-atom collisions. 2) Ultracold 3-atom systems: The recent experimental detection of Efimov states confirms the validity of his universal 3-body theory. I will apply this theory to ultracold atoms, and compare its results to calculations using model potentials, thus finding its limits and interpreting experimental data. I will explore 3-body physics as a tool for manipulation of atoms. 3) Optical lattices: I will continue to work with the Umeå group on dynamics of atoms in dissipative optical lattices, e.g. non-ergodic properties and a bi-modal interpretation of cooling. This includes double optical lattices, used e.g. for our Brownian motor. I will continue to develop my accurate and flexible semiclassical simulation method to three dimensions and double lattices.
