Few is different: deciphering many-body dynamics in mesoscopic quantum gases
Juergen Berges, Sandra Brandstetter, Jasmine Brewer +27
Emergent macroscopic descriptions of matter, such as hydrodynamics, are central to our description of complex physical systems across a wide spectrum of energy scales. The conventi…
Emergent quantum field theories on curved spacetimes in spinor Bose-Einstein condensates: from scalar to Proca fields
Christian F. Schmidt, Simon Brunner, Stefan Floerchinger
We consider excitations of a spin-1 Bose-Einstein-condensate (BEC) in the vicinity of different mean-field configurations and derive mappings to emergent relativistic quantum field…
Experimental particle production in time-dependent spacetimes: a one-dimensional scattering problem
Marius Sparn, Elinor Kath, Nikolas Liebster +7
We experimentally study cosmological particle production in a two-dimensional Bose-Einstein condensate, whose density excitations map to an analog cosmology. The expansion of space…
Quantum corrections at second order in derivatives to the dynamics of small non-relativistic fluids
Lars H. Heyen, Giuliano Giacalone, Stefan Floerchinger
To capture the dynamics of macroscopic non-relativistic fluids consisting of very many atoms, it is typically sufficient to truncate the gradient expansion at order zero, leading t…
Emergent interaction-driven elliptic flow of few fermionic atoms
Sandra Brandstetter, Philipp Lunt, Carl Heintze +8
Hydrodynamics provides a successful framework to effectively describe the dynamics of complex many-body systems ranging from subnuclear to cosmological scales by introducing macros…
Curved and expanding spacetime geometries in Bose-Einstein condensates
Mireia Tolosa-Simeón, Álvaro Parra-López, Natalia Sánchez-Kuntz +9
Phonons have the characteristic linear dispersion relation of massless relativistic particles. They arise as low energy excitations of Bose-Einstein condensates and, in nonhomogene…
