Observation of Temperature Effects on False Vacuum Decay in Atomic Quantum Gases
Riccardo Cominotti, Cosetta Baroni, Chiara Rogora +5
Temperature plays a crucial role in metastable phenomena, not only by contributing to determine the state (phase) of a system, but also ruling the decay probability to more stable…
Progress toward a zero-magnetic-field environment for ultracold-atom experiments
Chiara Rogora, Riccardo Cominotti, Cosetta Baroni +4
The minimization of the magnetic field plays a crucial role in ultracold gas research. For instance, the contact interaction dominates all the other energy scales in the zero magne…
Ultracold atomic spin mixtures in ultrastable magnetic field environments
Riccardo Cominotti, Chiara Rogora, Alessandro Zenesini +2
Ultracold atomic spin mixtures develop rich and intriguing magnetic properties when an external radiation coherently couples different spin states. In particular, the coupled mixtu…
Measurement of the order parameter and its spatial fluctuations across Bose-Einstein condensation
Wolswijk L., Mordini C., Farolfi A. +5
We investigate the strong out-of-equilibrium dynamics occurring when a harmonically trapped ultracold bosonic gas is evaporatively cooled across the Bose--Einstein condensation tra…
Measurement of the Canonical Equation of State of a Weakly Interacting 3D Bose Gas
C. Mordini, D. Trypogeorgos, A. Farolfi +4
Using a multiple-image reconstruction method applied to a harmonically trapped Bose gas, we determine the equation of state of uniform matter across the critical transition point,…
Observation of magnetic solitons in two-component Bose-Einstein condensates
A. Farolfi, D. Trypogeorgos, C. Mordini +2
We experimentally investigate the dynamics of spin solitary waves (magnetic solitons) in a harmonically trapped, binary superfluid mixture. We measure the in-situ density of each p…
Design and characterisation of a compact magnetic shield for ultracold atomic gas experiments
Arturo Farolfi, Dimitrios Trypogeorgos, Giacomo Colzi +3
We report on the design, construction, and performance of a compact magnetic shield that facilitates a controlled, low-noise environment for experiments with ultracold atomic gases…
Optical visibility and core structure of vortex filaments in a bosonic superfluid
Franco Dalfovo, Russell N. Bisset, Carmelo Mordini +2
We use optical images of a superfluid consisting of a weakly interacting Bose-Einstein condensate of sodium atoms to investigate the structure of quantized three-dimensional vortex…
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…
Increasing Quantum Degeneracy by Heating a Superfluid
D. J. Papoular, G. Ferrari, L. P. Pitaevskii +1
We consider a uniform superfluid confined in two compartments connected by a superleak and initially held at equal temperatures. If one of the two compartments is heated, a fractio…
