The -dimensional Gross-Neveu-Yukawa model at finite temperature, density, and magnetic field within the Functional Renormalization Group
Justin L. P. Mauldin, Dirk H. Rischke
We investigate the phase diagram of the (2+1)-dimensional Gross-Neveu-Yukawa (GNY) model at finite temperature, density, and magnetic field beyond mean-field, using the Functional…
Vector-Meson Spin Alignment from Anisotropic Quark or Hadron Coalescence
Wen-Bo Dong, Xin-Li Sheng, Yi-Liang Yin +2
The distribution of particles is highly anisotropic in the initial stage of a heavy-ion collision. In this paper we demonstrate that this anisotropy induces a sizable effect on the…
Analysis of regulator and cutoff artifacts in the phase diagram of the quark-meson model
Jonas Stoll, Niklas Zorbach, Lutz Kiefer +3
We study regulator and cutoff artifacts in the quark-meson model at finite temperature and quark chemical potential within the functional renormalization-group approach using the l…
Hyperon spin correlation in high-energy heavy-ion collisions
Xin-Li Sheng, Xiang-Yu Wu, Dirk H. Rischke +1
Recent experimental data show an unexpectedly large spin alignment of mesons in high-energy heavy-ion collisions, which can be explained by short-distance fluctuations of stro…
Gradient corrections to the local-equilibrium energy-momentum tensor in the Zubarev approach
Sergii V. Akkelin, Dirk H. Rischke
We compute the expectation value of the energy-momentum tensor of a real scalar field in an approximation which accounts for spacetime gradients of the hydrodynamical variables in…
