*Title: *Realizing Kondo-correlated states and dynamic phase transitions
with ultracold atoms
*Abstract*:
I will summarize our recent proposal of a novel realization of Kondo
physics with ultracold atomic gases. It is based on a Fermi sea of two
different hyperfine states of one atom species forming bound states with a
different species, which is spatially confined in a trapping potential. I
show that different situations displaying Kondo physics can be realized
when Feshbach resonances between the species are tuned by a magnetic field
and the trapping frequency is varied.
In the second part, I will also discuss some ongoing work on dynamic phase
transition. For a fermionic system with a weak coupling instability I will
present a non-equilibrium calculations to investigate the dynamics after
an interaction quench. I will show under which conditions unstable modes
are generated from a prethermal state and when we can expect to observe
transient ordered states.
