Shear and bulk viscosity for a pure glue theory using an effective matrix model
Manas Debnath, Ritesh Ghosh, Najmul Haque +2
At nonzero temperatures, the deconfining phase transition can be analyzed using an effective matrix model to characterize the change in holonomy. The model includes gluons and two-…
A New State of Matter between the Hadronic Phase and the Quark-Gluon Plasma?
Yuki Fujimoto, Kenji Fukushima, Yoshimasa Hidaka +1
Lattice-QCD simulations and theoretical arguments hint at the existence of an intermediate phase of strongly interacting matter between a confined hadron gas and a deconfined Quark…
Photon polarization tensor at finite temperature and density in a magnetic field
Kenji Fukushima, Yoshimasa Hidaka, Tomoya Uji
We present analytical and numerical calculations for the photon polarization tensor at finite temperature and density in a constant magnetic field. We first discuss the tensor deco…
Geometric conservation in curved spacetime and entropy
Sinya Aoki, Yoshimasa Hidaka, Kiyoharu Kawana +1
We provide an improved definition of new conserved quantities derived from the energy-momentum tensor in curved spacetime by introducing an additional scalar function. We find that…
