Observation of a Spinning Top in a Bose-Einstein Condensate
R. N. Bisset, S. Serafini, E. Iseni +5
Boundaries strongly affect the behavior of quantized vortices in Bose-Einstein condensates, a phenomenon particularly evident in elongated cigar-shaped traps where vortices tend to…
Vortex reconnections and rebounds in trapped atomic Bose--Einstein condensates
Simone Serafini, Luca Galantucci, Elena Iseni +6
Reconnections and interactions of filamentary coherent structures play a fundamental role in the dynamics of fluids, plasmas and nematic liquid crystals. In fluids, vortex reconnec…
Spin-Dipole Oscillation and Polarizability of a Binary Bose-Einstein Condensate near the Miscible-Immiscible Phase Transition
Tom Bienaimé, Eleonora Fava, Giacomo Colzi +6
We report on the measurement of the spin-dipole (SD) polarizability and of the frequency of the SD oscillation of a two-component Bose-Einstein condensate of sodium atoms occupying…
Creation and counting of defects in a temperature quenched Bose-Einstein Condensate
Simone Donadello, Simone Serafini, Tom Bienaimé +3
We study the spontaneous formation of defects in the order parameter of a trapped ultracold bosonic gas while crossing the critical temperature for Bose-Einstein Condensation (BEC)…
Sub-Doppler cooling of sodium atoms in gray molasses
Giacomo Colzi, Gianmaria Durastante, Eleonora Fava +3
We report on the realization of sub-Doppler laser cooling of sodium atoms in gray molasses using the D1 optical transition () at 589.8 nm…
Dynamics and interaction of vortex lines in an elongated Bose-Einstein condensate
Simone Serafini, Matteo Barbiero, Michele Debortoli +5
We study the real-time dynamics of vortex lines in a large elongated Bose-Einstein condensate (BEC) of sodium atoms using a stroboscopic technique. Vortices are spontaneously produ…
Solitonic Vortices in Bose-Einstein Condensates
Marek Tylutki, Simone Donadello, Simone Serafini +4
We analyse, theoretically and experimentally, the nature of solitonic vortices (SV) in an elongated Bose-Einstein condensate. In the experiment, such defects are created via the Ki…
Observation of Solitonic Vortices in Bose-Einstein Condensates
Simone Donadello, Simone Serafini, Marek Tylutki +4
We observe solitonic vortices in an atomic Bose-Einstein condensate after free expansion. Clear signatures of the nature of such defects are the twisted planar density depletion ar…
Spontaneous creation of Kibble-Zurek solitons in a Bose-Einstein condensate
Giacomo Lamporesi, Simone Donadello, Simone Serafini +2
When a system crosses a second-order phase transition on a finite timescale, spontaneous symmetry breaking can cause the development of domains with independent order parameters, w…
A compact high-flux source of cold sodium atoms
G. Lamporesi, S. Donadello, S. Serafini +1
We present a compact source of cold sodium atoms suitable for the production of quantum degenerate gases and versatile for a multi-species experiment. The magnetic field produced b…
