Parallel Session 6.3: New Theoretical Developments (II)
- Kari J. Eskola (University of Jyvaskyla)
The shear and the bulk relaxation times are important ingredients of the second order hydrodynamics whose success in heavy ion phenomenology is unquestioned. Unlike viscosites themselves, field theoretical calculations of the relaxation times are hard to come by in literature, especially for the bulk relaxation time. In this work, we report two field-theoretical analyses involving the shear...
Magnetic monopoles are suggested to play an important role in strongly coupled quark-gluon plasma (sQGP) near the deconfinement temperature. Lattice studies show that near the confinement temperature, $T_c$, quark-gluon plasma (QGP) contains both electric and magnetic quasiparticles. Further studies of the behavior of these quasiparticles at and above $T_c$, such as those by Liao and Shuryak...
We develop a set of kinetic equations for hydrodynamic fluctuations which are equivalent to nonlinear hydrodynamics with noise. The hydro-kinetic equations can be coupled to existing second order hydrodynamic codes to incorporate the physics of these fluctuations, which become dominant near the critical point.
We first show that the kinetic response precisely reproduces the renormalization...
We extend hydrodynamics of a fluid with conserved charge to incorporate the phenomenon of critical slowing down -- an essential ingredient for describing the dynamics of QCD matter near the critical point. We develop the general formalism of hydrodynamics with additional critically slow mode extending the validity of hydrodynamics in critical regime. As an application we consider a simple...
We study QCD for temperatures up to about 500 MeV using the lattice
approach. We include two generations of dynamical quarks, with
physical strange and charm masses, which are known to be relevant in the explored
temperature range. Our lattice discretization - Wilson quarks with a twisted
mass term - has good chiral properties at a moderate computational
cost. The main focus is...
