Thermal conductivity of hot pionic medium due to pion self-energy for and loops
Sabyasachi Ghosh
The thermal conductivity of pionic medium has been evaluated with the help of its standard expression from the relaxation time approximation, where inverse of pion relaxation time…
Shear viscosity of pionic and nucleonic components from their different possible mesonic and baryonic thermal fluctuations
Sabyasachi Ghosh
Owing to the Kubo relation, the shear viscosities of pionic and nucleonic components have been evaluated from their corresponding retarded correlators of viscous stress tensor in t…
Shear and Bulk Viscosities of Quark Matter from Quark-Meson Fluctuations in the Nambu--Jona-Lasinio model
Sabyasachi Ghosh, Thiago C. Peixoto, Victor Roy +2
We have calculated the temperature dependence of shear and bulk viscosities of quark matter due to quark-meson fluctuations. The quark thermal width originating from quantu…
A comparative study on two different expressions of Bulk viscosity in the PNJL model
Kinkar Saha, Sudipa Upadhaya, Sabyasachi Ghosh
We have gone through a comparative study on two different kind of bulk viscosity expressions by using a common dynamical model. The Polyakov-Nambu-Jona-Lasinio (PNJL) model in the…
The nucleon thermal width due to pion-baryon loops and its contribution in Shear viscosity
Sabyasachi Ghosh
In the real-time thermal field theory, the standard expression of shear viscosity for the nucleonic constituents is derived from the two point function of nucleonic viscous stress…
Low mass enhanced probability of pion in hadronic matter due to its Landau cut contributions
Sabyasachi Ghosh
In the real-time thermal field theory, the pion self-energy at finite temperature and density is evaluated where the different mesonic and baryonic loops are considered. The intera…
A comparative analysis of in-medium spectral functions for and in real-time thermal field theory
Sabyasachi Ghosh
In the real-time thermal field theory, the nucleon self-energy at finite temperature and density is evaluated where an extensive set of pion-baryon () loops are considered. On…
