Description
Among the large variety of quantum collective phenomena
that one hopes to address with atomic vapours, magnetism
is one of the richest. However the quest for the simulation
of magnetism immediately raises a challenging question:
how can a system of neutral atoms behave as an assembly
of charged particles in a magnetic field? The talk will review
some promising approaches to answer this question,
focusing in particular on the concept of “flux lattices”. I will
explain the principles at the basis of these lattices, which
allow one to reach with a quasi-flat lowest band with non-
trivial topological properties. I will also discuss why they are
well suited to produce atomic states that would be
analogous to fractional quantum Hall states.
