Roton softening and supersolidity in Rb spinor condensates
R. W. Cherng, E. Demler
Superfluids with a tendency towards periodic crystalline order have both a phonon and roton like spectrum of collective modes. The softening of the roton spectrum provides one rout…
Quantum Spin Dynamics of Mode-Squeezed Luttinger Liquids in Two-Component Atomic Gases
Artur Widera, Stefan Trotzky, Patrick Cheinet +6
We report on the observation of the phase dynamics of interacting one-dimensional ultracold bosonic gases with two internal degrees of freedom. By controlling the non-linear atomic…
Fundamental noise in matter interferometers
Adilet Imambekov, Vladimir Gritsev, Eugene Demler
These lecture notes discuss two effects which contribute to the reduction of the interference fringe contrast in matter interferometers. The first effect is the shot noise arising…
Noise-resistant entanglement of strongly interacting spin systems
A. M. Rey, L. Jiang, M. Fleischhauer +2
We propose and analyze a scheme that makes use of interactions between spins to protect certain correlated many-body states from decoherence. The method exploits the finite energy…
Linear response theory for a pair of coupled one-dimensional condensates of interacting atoms
Vladimir Gritsev, Anatoli Polkovnikov, Eugene Demler
We use quantum sine-Gordon model to describe the low energy dynamics of a pair of coupled one-dimensional condensates of interacting atoms. We show that the nontrivial excitation s…
