Behavior of universal critical parameters in the QCD phase diagram
Marcus Bluhm, Marlene Nahrgang, Steffen A. Bass +1
We determine the dependence of important parameters for critical fluctuations on temperature and baryon chemical potential in the QCD phase diagram. The analysis is based on an ide…
Impact of resonance decays on critical point signals in net-proton fluctuations
Marcus Bluhm, Marlene Nahrgang, Steffen A. Bass +1
The non-monotonic beam energy dependence of the higher cumulants of net-proton fluctuations is a widely studied signature of the conjectured presence of a critical point in the QCD…
Quantum Chromodynamics: Computational Aspects
Thomas Schaefer
We present a brief introduction to QCD, the QCD phase diagram, and non-equilibrium phenomena in QCD. We emphasize aspects of the theory that can be addressed using computational me…
A generalized Theory of Diffusion based on Kinetic Theory
Thomas Schaefer
We propose to use spin hydrodynamics, a two-fluid model of spin propagation, as a generalization of the diffusion equation. We show that in the dense limit spin hydrodynamics reduc…
Non-perturbative landscape of the Mott-Hubbard transition: Multiple divergence lines around the critical endpoint
T. Schäfer, S. Ciuchi, M. Wallerberger +5
We analyze the highly non-perturbative regime surrounding the Mott-Hubbard metal-to-insulator transition (MIT) by means of dynamical mean field theory calculations at the two-parti…
Quantum criticality with a twist - interplay of correlations and Kohn anomalies in three dimensions
T. Schäfer, A. A. Katanin, K. Held +1
A general understanding of quantum phase transitions in strongly correlated materials is still lacking. By exploiting a cutting-edge quantum many-body approach, the dynamical verte…
Chiral Lagrangian from Duality and Monopole Operators in Compactified QCD
Aleksey Cherman, Thomas Schaefer, Mithat Unsal
We show that there exists a special compactification of QCD on in which the theory has a domain where continuous chiral symmetry breaking is analytically…
