Query: An atom optics approach to studying lattice transport phenomena   We present a simple experimental scheme, based on standard atom optics
techniques, to design highly versatile model systems for the study of single
particle quantum transport phenomena. The scheme is based on a discrete set of
free-particle momentum states that are coupled via momentum-changing two-photon
Bragg transitions, driven by pairs of interfering laser beams. In the effective
lattice models that are accessible, this scheme allows for single-site
detection, as well as site-resolved and dynamical control over all system
parameters. We discuss two possible implementations, based on state-preserving
Bragg transitions and on state-changing Raman transitions, which respectively
allow for the study of nearly arbitrary single particle Abelian U(1) and
non-Abelian U(2) lattice models.
