Tricritical dynamics in - mixtures and QCD
Maneesha Pradeep, Johannes V. Roth, Lorenz von Smekal
In this paper we study the universal critical dynamics near the tricritical points in - mixtures and QCD with two massless quark flavors. In particula…
Renormalization-Group Invariant Parity-Doublet Model for Nuclear and Neutron-Star Matter
Mattia Recchi, Lorenz von Smekal, Jochen Wambach
The Parity-Doublet Model (PDM) is a chirally invariant effective theory for strong-interaction matter involving nucleons and their opposite-parity partners in a parity-doubling fra…
Non-equilibrium scaling across first-order transitions with relativistic scalar fields
Leon J. Sieke, Jessica Fuchs, Lorenz von Smekal
We investigate the out-of-equilibrium dynamics of a relativistic -symmetric scalar field theory with Langevin dynamics in two and three spatial dimensions under linear driving…
QCD Anderson transition at zero and non-zero external magnetic fields
Robin Kehr, Adeilton Dean Marques Valois, Lorenz von Smekal
The QCD Anderson transition is believed to be connected to both deconfinement and chiral crossovers. These crossovers are substantially affected when external magnetic fields ()…
Universal scaling of transport coefficients near the liquid-gas critical point
Johannes V. Roth, Yunxin Ye, Sören Schlichting +1
We employ a novel real-time formulation of the functional renormalization group (FRG) to compute universal scaling functions of the thermal diffusivity and the shear viscosity in t…
Kinetic Mixing and Axial Charges in the Parity-Doublet Model
Christian Kummer, Stefan Leupold, Lorenz von Smekal
The standard parity doublet model with its mass-mixing mechanism fails to describe the axial charge of the nucleon. While in the original Gell-Mann--Levy model, whi…
