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…
Ferromagnetism in an extended coherently-coupled atomic superfluid
Riccardo Cominotti, Anna Berti, Clement Dulin +6
Ferromagnetism is an iconic example of a first-order phase transition taking place in spatially extended systems and is characterized by hysteresis and the formation of domain wall…
Observation of Massless and Massive Collective Excitations with Faraday Patterns in a Two-Component Superfluid
Riccardo Cominotti, Anna Berti, Arturo Farolfi +5
We report on the experimental measurement of the dispersion relation of the density and spin collective excitation modes in an elongated two-component superfluid of ultracold boson…
Manipulation of an elongated internal Josephson junction of bosonic atoms
A. Farolfi, A. Zenesini, R. Cominotti +4
We report on the experimental characterization of a spatially extended Josephson junction realized with a coherently-coupled two-spin-component Bose-Einstein condensate. The cloud…
