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…
Single-particle spectra and magnetic susceptibility in the Emery model: a dynamical mean-field perspective
Yi-Ting Tseng, Mário O. Malcolms, Henri Menke +3
We investigate dynamical mean-field calculations of the three-band Emery model at the one- and two-particle level for material-realistic parameters of high- superconductors. O…
Mott transition and pseudogap of the square-lattice Hubbard model: results from center-focused cellular dynamical mean-field theory
Michael Meixner, Henri Menke, Marcel Klett +4
The recently proposed center-focused post-processing procedure [Phys. Rev. Research 2, 033476 (2020)] of cellular dynamical mean-field theory suggests that central sites of large i…
Thermodynamic Stability at the Two-Particle Level
A. Kowalski, M. Reitner, L. Del Re +6
We show how the stability conditions for a system of interacting fermions that conventionally involve variations of thermodynamic potentials can be rewritten in terms of one- and t…
Fluid dynamics from the Boltzmann equation using a maximum entropy distribution
Chandrodoy Chattopadhyay, Ulrich Heinz, Thomas Schaefer
Using the recently developed ``Maximum Entropy'' (or ``least biased'') distribution function to truncate the moment hierarchy arising from kinetic theory, we formulate a far-from-e…
Magnetism and Metallicity in Moiré Transition Metal Dichalcogenides
Patrick Tscheppe, Jiawei Zang, Marcel Klett +8
The ability to control the properties of twisted bilayer transition metal dichalcogenides in situ makes them an ideal platform for investigating the interplay of strong correlation…
Dynamic scaling of order parameter fluctuations in model B
Chandrodoy Chattopadhyay, Josh Ott, Thomas Schaefer +1
We describe numerical simulations of the stochastic diffusion equation with a conserved charge. We focus on the dynamics in the vicinity of a critical point in the Ising universali…
N-particle irreducible actions for stochastic fluids
Jingyi Chao, Thomas Schaefer
We construct one- and two-particle irreducible (1PI and 2PI) effective actions for the stochastic fluid dynamics of a conserved density undergoing diffusive motion. We compute the…
