Measuring the dynamic structure factor of a quantum gas undergoing a structural phase transition
Renate Landig, Ferdinand Brennecke, Rafael Mottl +2
The dynamic structure factor is a central quantity describing the physics of quantum many-body systems, capturing structure and collective excitations of a material. In condensed m…

Roton-type mode softening in a quantum gas with cavity-mediated long-range interactions
R. Mottl, F. Brennecke, K. Baumann +3
Long-range interactions in quantum gases are predicted to give rise to an excitation spectrum of roton character, similar to that observed in superfluid helium. We investigate the…
