Hybridization of the amplitude mode in a confined fermionic superfluid
Cesar R. Cabrera, René Henke, Lukas Broers +5
In phase transitions, spontaneous symmetry breaking results in a non-zero order parameter and two collective excitations: the Goldstone and the amplitude mode. These modes, which d…

Frustrated extended Bose-Hubbard model and deconfined quantum critical points with optical lattices at the anti-magic wavelength
Niccolò Baldelli, Cesar R. Cabrera, Sergi Julià -Farré +2
The study of geometrically frustrated many-body quantum systems is of central importance to uncover novel quantum mechanical effects. We design a scheme where ultracold bosons trap…
