Magnetoviscosity of relativistic plasma
Ritesh Ghosh, Igor A. Shovkovy
Using first-principles quantum field-theoretical methods, we investigate the shear and bulk viscosities of strongly magnetized relativistic plasmas. The analysis is performed withi…
Quarkonium in a QCD medium with momentum-dependent relaxation time
Sunny Kumar Singh, Samapan Bhadury, Ritesh Ghosh +1
In this study, we explore the properties of quarkonia in a hot QCD medium using a newly proposed collision kernel that consistently incorporates the particle's momentum dependence…
Review of heat and charge transport in strongly magnetized relativistic plasmas
Igor A. Shovkovy, Ritesh Ghosh
We review field-theoretic studies of charge transport in hot relativistic plasmas under strong magnetic fields and extend the analysis to thermal conductivity. The calculations rel…
Neutrino-antineutrino synchrotron emission from magnetized dense quark matter
Ritesh Ghosh, Igor A. Shovkovy
Using the Kadanoff-Baym formalism, we perform a detailed study of neutrino-antineutrino synchrotron emission from strongly magnetized, dense quark matter under conditions relevant…
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-…
Neutrino energy and momentum emission from magnetized dense quark matter
Ritesh Ghosh, Igor A. Shovkovy
Using first-principles field-theoretic methods, we investigate neutrino emission from strongly magnetized dense quark matter under conditions relevant to compact stars. We develop…
