Non-perturbative effects of short-range spatial correlations at the two-particle level
Michael Meixner, Matthias Reitner, Thomas Schäfer +1
By means of cellular dynamical mean-field theory (CDMFT) we study how short-range correlations drive the breakdown of the self-consistent perturbation theory in two-dimensional sys…

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…
