Stability and excitations of solitons in 2D Bose-Einstein condensates
S. Tsuchiya, F. Dalfovo, C. Tozzo +1
The small oscillations of solitons in 2D Bose-Einstein condensates are investigated by solving the Kadomtsev-Petviashvili equation which is valid when the velocity of the soliton a…
Detecting phonons and persistent currents in toroidal Bose-Einstein condensates by means of pattern formation
M. Modugno, C. Tozzo, F. Dalfovo
We theoretically investigate the dynamic properties of a Bose-Einstein condensate in a toroidal trap. A periodic modulation of the transverse confinement is shown to produce a dens…
Vortex lattices in Bose-Einstein condensates: from the Thomas-Fermi to the lowest Landau level regime
M. Cozzini, S. Stringari, C. Tozzo
We consider a periodic vortex lattice in a rotating Bose-Einstein condensed gas, where the centrifugal potential is exactly compensated by the external harmonic trap. By introducin…
Stability diagram and growth rate of parametric resonances in Bose-Einstein condensates in one-dimensional optical lattices
C. Tozzo, M. Kraemer, F. Dalfovo
A Bose-Einstein condensate in an optical lattice exhibits parametric resonances when the intensity of the lattice is periodically modulated in time. These resonances correspond to…
Parametric excitation of a Bose-Einstein condensate in a 1D optical lattice
M. Kraemer, C. Tozzo, F. Dalfovo
We study the response of a Bose-Einstein condensate to a periodic modulation of the depth of an optical lattice. Using Gross-Pitaevskii theory, we show that a modulation at frequen…
High sensitivity phonon spectroscopy of Bose-Einstein condensates using matter-wave interference
N. Katz, R. Ozeri, J. Steinhauer +3
We study low momentum excitations of a Bose-Einstein condensate using a novel matter-wave interference technique. In time-of-flight expansion images we observe strong matter-wave f…
