Spielman's current experiments lie at the intersection of condensed matter and atomic physics, realizing many-body systems with systems of ultra-cold atoms.
Current projects: (1) creating magnetic/optical configurations leading to synthetic gauge fields, for example, making the charge neutral bosons or fermions move like charged particles in a magnetic field, or act as if they experience the classic Rashba and Dresselhaus spin-orbit couplings; (2) using Feshbach resonances in 40K to control interactions Hamiltonians; (3) studying ultracold 87Rb in a optical lattices, thus realizing the 2D Bose-Hubbard model; and (4) realizing artificial gauge fields using the RF fields produced by an atom chip.
