- Abstract: Motivated by recent cold-atom realisations of matter-wave waveguide QED, we
study simple fermionic impurity models and discuss fermionic analogues of
several paradigmatic phenomena in quantum optics, including formation of
non-trivial bound states, (matter-wave) emission dynamics, and collective
dissipation. For a single impurity, we highlight interesting ground-state
features, focusing in particular on real-space signatures of an emergent length
scale associated with an impurity screening cloud. We also present novel
non-Markovian many-body effects in the quench dynamics of single- and
multiple-impurity systems, including fractional decay around the Fermi level
and multi-excitation population trapping due to bound states in the continuum.

Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems.
We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons.
We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

Recent experimental advances in the field of cold-atom cavity QED provide a powerful tool for exploring non-equilibrium correlated quantum phenomena.
We present the dynamical phase diagram of a driven Bose-Einstein condensate coupled with the light field of a cavity, with a transverse driving field red-detuned from atomic resonance.
We identify regions in parameter space showing dynamical instabilities in the form of limit cycles, which evolve into chaotic behavior in the strong driving limit.
