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…
Many-Body Phases of a Planar Bose-Einstein Condensate with Cavity-Induced Spin-Orbit Coupling
Stefan Ostermann, Helmut Ritsch, Farokh Mivehvar
We explore the many-body phases of a two-dimensional Bose-Einstein condensate with cavity-mediated dynamic spin-orbit coupling. By the help of two transverse non-interfering, count…
Spin and density self-ordering in dynamic polarization gradients fields
Natalia Masalaeva, Wolfgang Niedenzu, Farokh Mivehvar +1
We study the zero-temperature quantum phase diagram for a two-component Bose-Einstein condensate in an optical cavity. The two atomic spin states are Raman coupled by two transvers…
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…
A supersolid-based gravimeter in a ring cavity
Karol Gietka, Farokh Mivehvar, Helmut Ritsch
We propose a novel type of composite light-matter interferometer based on a supersolid-like phase of a driven Bose-Einstein condensate coupled to a pair of degenerate counterpropag…
