Floquet-Engineering of Feshbach Resonances in Ultracold Gases
Alexander Guthmann, Felix Lang, Louisa Marie Kienesberger +2
Scattering resonances are fundamental in science, spanning energy scales from stellar nuclear fusion to ultracold collisions. In ultracold quantum gases, magnetic Feshbach resonanc…

Stability and sensitivity of interacting fermionic superfluids to quenched disorder
Jennifer Koch, Sian Barbosa, Felix Lang +1
The microscopic pair structure of superfluids has profound consequences on their properties. Delocalized pairs are predicted to be less affected by static disorder than localized p…

Stabilizing an ultracold Fermi gas against Fermi acceleration to superdiffusion through localization
Sian Barbosa, Maximilian Kiefer-Emmanouilidis, Felix Lang +2
Anderson localization, i.e., destructive quantum interference of multiple-scattering paths, halts transport entirely. Contrarily, time-dependent random forces expedite transport vi…
