Quantum-enabled active matter at the atomic scale
Sabrina Burgardt, Julian FeÃ, Alexander Guthmann +8
Active matter comprises particles that extract energy from their local environment and convert it into motion. Although active particles have been miniaturized down to the nanoscal…

Engineering a Bound State in the Continuum via Quantum Interference
Alexander Guthmann, Louisa Marie Kienesberger, Felix Lang +2
Quantum mechanical interaction potentials typically support either localized bound states below the dissociation threshold or delocalized scattering states above it. While bound st…

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…
