Extended applicability domain of viscous anisotropic hydrodynamics in (2+1)-D Bjorken flow with transverse expansion
Yiyang Peng, Victor E. Ambrus, Clemens Werthmann +3
We perform (2+1)-D simulations of viscous anisotropic hydrodynamics (VAH) under boost-invariant and conformal conditions. Comparing both VAH and traditional viscous hydrodynamics w…
Linear sigma model with quarks and Polyakov loop in rotation: phase diagrams, Tolman-Ehrenfest law and mechanical properties
Pracheta Singha, Sergiu Busuioc, Victor E. Ambrus +1
We study the effect of rotation on the confining and chiral properties of QCD using the Polyakov-enhanced linear sigma model coupled to quarks. Working in the homogeneous approxima…
Firewall boundaries and mixed phases of rotating quark matter in linear sigma model
Sergio Morales-Tejera, Victor E. AmbruÅ, Maxim N. Chernodub
A rigidly-rotating body in unbounded space is usually considered a pathological system since it leads to faster-than-light velocities and associated breaches of causality. However,…
Chiral restoration temperature at finite spin density in QCD
Pracheta Singha, Victor E. Ambrus, Sergiu Busuioc +2
We investigate the impact of a uniform spin density on the critical temperature of the chiral phase transition in finite-temperature QCD in the scope of the linear sigma model. We…
High-order Shakhov-like extension of the relaxation time approximation in relativistic kinetic theory
Victor E. AmbruÅ, David Wagner
In this paper we present a relativistic Shakhov-type generalization of the Anderson-Witting relaxation time model for the Boltzmann collision integral. The extension is performed b…
Shakhov-type extension of the relaxation time approximation in relativistic kinetic theory and second-order fluid dynamics
Victor E. AmbruÅ, Etele Molnár
We present a relativistic Shakhov-type generalization of the Anderson-Witting relaxation time model for the Boltzmann collision integral to modify the ratio of momentum diffusivity…
