However, the complexity of their interactions generally prevents us from
coming up with an exact mathematical description of their behavior.
Precisely engineered ultracold gases are emerging as a powerful tool for
unraveling these challenging physical problems. In this talk, I will
present recent ideas on using alkaline-earth atoms (AEAs) --currently
the basis of the most precise atomic clock in the world-- for the
investigation of complex many-body phenomena and magnetism. I will
discuss ideas to use AEAs dressed by laser fields to engineer analogs of
spin-orbit coupled Hamiltonians which can display topologically
quantized particle transport and which in the presence of interactions
exhibit peculiar laser field-induced Kondo-type resonances that
significantly alter particle transport. I will also discuss how Weyl
quasiparticles can naturally emerge when AEAs populate electronic
excited states.
