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…

Antiferromagnetic self-ordering of a Fermi gas in a ring cavity
Elvia Colella, Stefan Ostermann, Wolfgang Niedenzu +2
We explore the density and spin self-ordering of driven spin- collisionless fermionic atoms coupled to the electromagnetic fields of a ring resonator. The two spin states are…
