We estimate the photon production rate from an SU(3) plasma at
temperatures of about $1.1~T_c$ and $1.3~T_c$. Lattice results for the
vector current correlator at spatial momenta $k\sim (2-6)T$ are
extrapolated to the continuum limit and analyzed with the help of a
polynomial interpolation for the corresponding spectral function,
which vanishes at zero frequency and matches to...

We study the transport coefficient for the charm quark in the deconfined phase from
correlator in the temporal channel with nonzero momentum on the quenched lattice.
Lattice Euclidean correlator in the temporal channel with zero momentum is constant
as a function of the imaginary time because of the charge conservation.
However, the derivative of the correlator with respect to momentum...

This report is devoted to the study of temperature dependence of shear viscosity in SU(3)-gluodynamics.
To calculate shear viscosity we measured the correlation function of the energy-momentum tensor
T_{12}T_{12} for a set of temperatures in the region T/T_c \in (0.9, 1.5). The measurements
were carried out using multilevel algorithm which considerably improves the accuracy
of the...

We apply the gradient flow method to Nf=2+1 full QCD at finite temperature.
Our main interest is on temperature dependence of:
1. energy-momentum tensor with quark contribution,
2. chiral condensate and its susceptibility.
We show that these observables are well measured with the gradient flow method.
Our finite temperature system is constructed by fixing the lattice spacing and...

We numerically simulate gravitational shock wave collisions in a holographic model dual to a non-conformal four-dimensional gauge theory. We find two novel effects associated to the non-zero bulk viscosity of the resulting plasma. First, the hydrodynamization time increases. Second, if the bulk viscosity is large enough then the plasma becomes well described by hydrodynamics before the...

The thermal Sommerfeld factor, concerning the co-annihilation rate
of heavy quarks in thermal equilibrium, is shown that it can be
defined in terms of two-point correlator ratios. Then, we calculate
non-perturbatively the co-annihilation rate of heavy quarks close to
thermal equilibrium using lattice NRQCD framework. Lattice
measurements indicate a modest suppression in the octet channel,...

In nonrelativistic many-body systems, rotation produces interesting phenomena as well as external electromagnetic field and finite chemical potential. On the other hand rotational effects on relativistic systems have not been elucidated. Nevertheless it is known that a rapid rotation is realized in main objectives of QCD physics: heavy-ion collisions and neutron stars. In this talk, we...
