Microscopy of cavity-induced density-wave ordering in ultracold gases
Tabea Bühler, Aurélien Fabre, Gaia Bolognini +4
We demonstrate high-resolution in-situ imaging of density-wave ordering induced by cavity-mediated interactions in a unitary Fermi gas. We observe long-range spatial correlations t…
Cavity-mediated charge and pair-density waves in a unitary Fermi gas
Timo Zwettler, Filip Marijanović, Tabea Bühler +7
Coherent light-matter interactions between a quantum gas and light in a high-finesse cavity can drive self-ordering phase transitions. To date, such phenomena have involved exclusi…
Direct production of fermionic superfluids in a cavity-enhanced optical dipole trap
Tabea Bühler, Timo Zwettler, Gaia Bolognini +4
We present the production of quantum degenerate, superfluid gases of Li through direct evaporative cooling in a cavity-enhanced optical dipole trap. The entire evaporative cool…
Simple, highly-stable transfer cavity for laser stabilization based on a carbon-fiber reinforced polymer spacer
Timo Zwettler, Zeyang Xue, Gaia Bolognini +5
We describe the design and operation of a high-stability Fabry-Perot cavity, for laser stabilization in cavity quantum-electrodynamics experiments. Our design is based on an inexpe…
Dynamical Instabilities of Strongly Interacting Ultracold Fermions in an Optical Cavity
Filip Marijanović, Sambuddha Chattopadhyay, Luka Skolc +6
Recent quench experiments on ultra cold fermions in optical cavities provide a clean platform for studying how long-range interactions between fermions structure their dynamics. Mo…
Non-equilibrium dynamics of long-range interacting Fermions
Timo Zwettler, Giulia del Pace, Filip Marijanovic +12
A fundamental problem of out-of-equilibrium physics is the speed at which the order parameter grows upon crossing a phase transition. Here, we investigate the dynamics of ordering…
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…
Optomechanical Response of a Strongly Interacting Fermi Gas
Victor Helson, Timo Zwettler, Kevin Roux +3
We study a Fermi gas with strong, tunable interactions dispersively coupled to a high-finesse cavity. Upon probing the system along the cavity axis, we observe a strong optomechani…
High-frequency broadband laser phase noise cancellation using a delay line
Michał Parniak, Ivan Galinskiy, Timo Zwettler +1
Laser phase noise remains a limiting factor in many experimental settings, including metrology, time-keeping, as well as quantum optics. Hitherto this issue was addressed at low fr…
