Fermionic pairs, from the surface to the bulk
Sandra Brandstetter, Carl Heintze, Fabian Brauneis +4
Fermion pairing underlies collective quantum phenomena across widely different forms of matter. In extended systems such as ultracold Fermi gases, pairing is commonly understood th…
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…
Exploring molecular supersolidity via exact and mean-field theories: single microwave shielding
Tiziano Arnone Cardinale, Thomas Bland, Stephanie M. Reimann
Ultracold polar molecules with microwave shielding provide a powerful platform for exploring quantum many-body physics with strong, anisotropic interactions. We develop an extended…
Comparison of renormalized interactions using one-dimensional few-body systems as a testbed
Fabian Brauneis, Hans-Werner Hammer, Stephanie M. Reimann +1
Even though the one-dimensional contact interaction requires no regularization, renormalization methods have been shown to improve the convergence of numerical ab initio calculatio…
