Analog Hawking radiation from a spin-sonic horizon in a two-component Bose-Einstein condensate
Anna Berti, Lennart Fernandes, Salvatore Giulio Butera +3
We theoretically study stimulated and spontaneous Hawking emission from an analog horizon for spin modes in a two-component Bose-Einstein condensate, both with and without a cohere…
Superradiant phononic emission from the analog spin ergoregion in a two-component Bose-Einstein condensate
Anna Berti, Luca Giacomelli, Iacopo Carusotto
We make use of an analog gravity perspective to obtain a physical understanding of hydrodynamic instabilities stemming from the presence of quantized vortices in two-component atom…
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…
