Abstract:
In an effort to explore many-body and strongly correlated systems through quantum simulations with ultracold atoms, experimentalists continue to develop new tools for manipulating and measuring atomic systems with versatility and precision. By exploiting the momentum transfer between light and atoms during the absorption and emission of photons in Raman processes, we are able to modify the single-particle dispersion relationship and engineer environments that effect simulated magnetic fields or spin-coupling for ultracold atoms. Using these techniques, we have explored a number of applications within these environments. I will focus on two recent experiments: In one, we measured the analogue of the Hall effect in a Bose-Einstein condensate in an artificial magnetic field. In another, we engineered a 1+1 dimensional Dirac Hamiltonian that allowed for the direct measurement of zitterbewegung in a BEC. I will also mention other recent work in our laboratory, including a measurement of the spin Hall effect and our progress towards engineering a spin-orbit coupling dispersion relationship for fermions.
