Stability of dark solitons in three dimensional dipolar Bose-Einstein condensates
R. Nath, P. Pedri, L. Santos
The dynamical stability of dark solitons in dipolar Bose-Einstein condensates is studied. For standard short-range interacting condensates dark solitons are unstable against transv…
Collective excitations of trapped one-dimensional dipolar quantum gases
P. Pedri, S. De Palo, E. Orignac +2
We calculate the excitation modes of a 1D dipolar quantum gas confined in a harmonic trap with frequency and predict how the frequency of the breathing n=2 mode characterizes…
Kelvon-roton instability of vortex lines in dipolar Bose-Einstein condensates
M. Klawunn, R. Nath, P. Pedri +1
The physics of vortex lines in dipolar condensates is studied. Due to the nonlocality of the dipolar interaction, the 3D character of the vortex plays a more important role in dipo…
Expansion dynamics of a dipolar Bose-Einstein condensate
S. Giovanazzi, P. Pedri, L. Santos +5
Our recent measurements on the expansion of a chromium dipolar condensate after release from an optical trapping potential are in good agreement with an exact solution of the hydro…
Observation of dipole-dipole interaction in a degenerate quantum gas
J. Stuhler, A. Griesmaier, T. Koch +5
We have investigated the expansion of a Bose-Einstein condensate (BEC) of strongly magnetic chromium atoms. The long-range and anisotropic magnetic dipole-dipole interaction leads…
Two-dimensional bright solitons in dipolar Bose-Einstein condensates
P. Pedri, L. Santos
We analyze the physics of bright solitons in two-dimensional dipolar Bose-Einstein condensates. These solitons are not possible in short-range interacting gases. In particular, we…
