Decoherence and momentum relaxation in Fermi-polaron Rabi dynamics: a kinetic equation approach
Tomasz Wasak, Matteo Sighinolfi, Johannes Lang +2
Despite the paradigmatic nature of the Fermi-polaron model, the theoretical description of its nonlinear dynamics poses challenges. Here, we apply a quantum kinetic theory of drive…
Light-induced quantum droplet phases of lattice bosons in multimode cavities
P. Karpov, F. Piazza
Multimode optical cavities can be used to implement interatomic interactions which are highly tunable in strength and range. For bosonic atoms trapped in an optical lattice, cavity…
Cavity QED with Quantum Gases: New Paradigms in Many-Body Physics
Farokh Mivehvar, Francesco Piazza, Tobias Donner +1
We review the recent developments and the current status in the field of quantum-gas cavity QED. Since the first experimental demonstration of atomic self-ordering in a system comp…
The Hofstadter Butterfly in a Dynamic Cavity-Induced Synthetic Magnetic Field
Elvia Colella, Farokh Mivehvar, Francesco Piazza +1
Energy bands of electrons in a square lattice potential threaded by a uniform magnetic field exhibit a fractal structure known as the Hofstadter butterfly. Here we study a Fermi ga…
Emergent Quasicrystalline Symmetry in Light-Induced Quantum Phase Transitions
Farokh Mivehvar, Helmut Ritsch, Francesco Piazza
The discovery of quasicrystals with crystallographically forbidden rotational symmetries has changed the notion of the ordering in materials, yet little is known about the dynamica…
Interaction-induced transparency for strong-coupling polaritons
Johannes Lang, Darrick E. Chang, Francesco Piazza
The propagation of light in strongly coupled atomic media takes place through the formation of polaritons - hybrid quasi-particles resulting from a superposition of an atomic and a…
