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…
Monte Carlo matrix-product-state approach to the false vacuum decay in the monitored quantum Ising chain
Jeff Maki, Anna Berti, Iacopo Carusotto +1
In this work we characterize the false vacuum decay in the ferromagnetic quantum Ising chain with a weak longitudinal field subject to continuous monitoring of the local magnetizat…
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…
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…
Topological two-particle dynamics in a periodically driven lattice model with on-site interactions
Anna Berti, Iacopo Carusotto
We develop a realistic protocol to observe a robust topological dynamics of two-particle bound states in a lattice model with on-site interactions and suitably designed time-depend…
