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…
Magnetic quantum criticality: The role of the Fermi surface geometry
D. R. Fus, S. Adler, M. O. Malcolms +5
We investigate magnetic quantum phase-transitions in bulk correlated metals. To this end, we focus on the Hubbard model on different cubic lattices as a function of temperature and…
Simulations of stochastic fluid dynamics near a critical point in the phase diagram
Chandrodoy Chattopadhyay, Josh Ott, Thomas Schaefer +1
We present simulations of stochastic fluid dynamics in the vicinity of a critical endpoint belonging to the universality class of the Ising model. This study is motivated by the ch…
Superconductivity and Mottness in Organic Charge Transfer Materials
Henri Menke, Marcel Klett, Kazushi Kanoda +3
The phase diagrams of quasi two-dimensional organic superconductors display a plethora of fundamental phenomena associated with strong electron correlations, such as unconventional…
Far-off-equilibrium early-stage dynamics in high-energy nuclear collisions
Chandrodoy Chattopadhyay, Ulrich Heinz, Thomas Schaefer
We explore the far-off-equilibrium aspects of the (1+1)-dimensional early-stage evolution of a weakly-coupled quark-gluon plasma using kinetic theory and hydrodynamics. For a large…
