Density-wave ordering in a unitary Fermi gas with photon-mediated interactions
Victor Helson, Timo Zwettler, Farokh Mivehvar +5
A density wave (DW) is a fundamental type of long-range order in quantum matter tied to self-organization into a crystalline structure. The interplay of DW order with superfluidity…
Squeezing and overcoming the Heisenberg scaling with spin-orbit coupled quantum gases
Karol Gietka, Helmut Ritsch
We predict that exploiting spin-orbit coupling in a harmonically trapped spinor quantum gas can lead to scaling of the optimal measurement precision beyond the Heisenberg scaling.…
Control of Localized Multiple Excitation Dark States in Waveguide QED
Raphael Holzinger, Ricardo Gutierrez-Jauregui, Teresa Hönigl-Decrinis +3
Subradiant excited states in finite chains of two-level quantum emitters coupled to a one-dimensional reservoir are a resource for superior photon storage and controlled photon man…
Nonequilibrium phases of ultracold bosons with cavity-induced dynamic gauge fields
Arkadiusz Kosior, Helmut Ritsch, Farokh Mivehvar
Gauge fields are a central concept in fundamental theories of physics, and responsible for mediating long-range interactions between elementary particles. Recently, it has been pro…
Cooperative subwavelength molecular quantum emitter arrays
Raphael Holzinger, Sue Ann Oh, Michael Reitz +2
Dipole-coupled subwavelength quantum emitter arrays respond cooperatively to external light fields as they may host collective delocalized excitations (a form of excitons) with sup…
Cavity Sub- and Superradiance Enhanced Ramsey Spectroscopy
Christoph Hotter, Laurin Ostermann, Helmut Ritsch
Ramsey spectroscopy in large, dense ensembles of ultra-cold atoms trapped in optical lattices suffers from dipole-dipole interaction induced shifts and collective superradiance lim…
