Momentum Entanglement for Atom Interferometry
F. Anders, A. Idel, P. Feldmann +13
Compared to light interferometers, the flux in cold-atom interferometers is low and the associated shot noise large. Sensitivities beyond these limitations require the preparation…

Excited-state quantum phase transitions in spinor Bose-Einstein condensates
Polina Feldmann, Carsten Klempt, Augusto Smerzi +2
Excited-state quantum phase transitions (ESQPTs) extend the notion of quantum phase transitions beyond the ground state. They are characterized by closing energy gaps amid the spec…
