Observation of false vacuum decay via bubble formation in ferromagnetic superfluids
Alessandro Zenesini, Anna Berti, Riccardo Cominotti +7
In quantum field theory, the decay of an extended metastable state into the real ground state is known as ``false vacuum decay'' and it takes place via the nucleation of spatially…
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…
Oscillating Solitons and AC Josephson Effect in Ferromagnetic Bose-Bose Mixtures
Sebastiano Bresolin, Arko Roy, Gabriele Ferrari +2
Close to the demixing transition, the degree of freedom associated to relative density fluctuations of a two-component Bose-Einstein condensate is described by a non-dissipative La…
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…
Quantum-torque-induced breaking of magnetic interfaces in ultracold gases
Arturo Farolfi, Alessandro Zenesini, Dimitris Trypogeorgos +6
A rich variety of physical effects in spin dynamics arises at the interface between different magnetic materials. Engineered systems with interlaced magnetic structures have been u…
