Time-of-Flight Roton Spectroscopy in Dipolar Bose-Einstein Condensates
M. Jona-Lasinio, K. Łakomy, L. Santos
Dipolar Bose-Einstein condensates may present a rotonlike dispersion minimum, which has yet to be observed in experiments. We discuss a simple method to reveal roton excitations, b…
Self-bound many-body states of quasi-one-dimensional dipolar Fermi gases: Exploiting Bose-Fermi mappings for generalized contact interactions
F. Deuretzbacher, G. M. Bruun, C. J. Pethick +3
Using a combination of results from exact mappings and from mean-field theory we explore the phase diagram of quasi-one-dimensional systems of identical fermions with attractive di…
Spatial analysis of wave direction data using wrapped Gaussian processes
Giovanna Jona-Lasinio, Alan Gelfand, Mattia Jona-Lasinio
Directional data arise in various contexts such as oceanography (wave directions) and meteorology (wind directions), as well as with measurements on a periodic scale (weekdays, hou…
Roton confinement in trapped dipolar Bose-Einstein condensates
M. Jona-Lasinio, K. Łakomy, L. Santos
Roton excitations constitute a key feature of dipolar gases, connecting these gases with superfluid helium. We show that the density dependence of the roton minimum results in a sp…
Confinement-induced collapse of a dipolar Bose-Einstein condensate
J. Billy, E. A. L. Henn, S. Müller +6
We report on the observation of the confinement-induced collapse dynamics of a dipolar Bose-Einstein condensate (dBEC) in a one-dimensional optical lattice. We show that for a fixe…
Dipolar Stabilization of an Attractive Bose Gas in a One Dimensional Lattice
S. Müller, J. Billy, E. A. L. Henn +5
We experimentally show that dipolar interaction can stabilize otherwise unstable many-body systems like an attractive Bose gas. In a one dimensional lattice the repulsive dipolar o…
