Description
We show how density dependent gauge potentials can be
induced in dilute gases of ultracold atoms using
light-matter interactions. We study the effect of the
resulting interacting gauge theory and show how it gives
rise to novel topological states in the ultracold gas. We
find in particular that the onset of persistent currents in
a ring geometry is governed by a critical number of
particles. The density-dependent gauge potential is also
found to support chiral solitons in a quasi-one-dimensional
ultracold Bose gas.
