Far-from-equilibrium attractor in non-conformal plasmas
Sunil Jaiswal, Subrata Pal, Chandrodoy Chattopadhyay +2
We study the far-off-equilibrium dynamics of a Bjorken expanding non-conformal system within kinetic theory and hydrodynamics. We show that, in contrast to the conformal case, neit…
On non-conformal kinetic theory and hydrodynamics for Bjorken flow
Sunil Jaiswal, Chandrodoy Chattopadhyay, Lipei Du +2
Using and comparing kinetic theory and second-order Chapman-Enskog hydrodynamics, we study the non-conformal dynamics of a system undergoing Bjorken expansion. We use the concept o…
Non-conformal attractor in boost-invariant plasmas
Chandrodoy Chattopadhyay, Sunil Jaiswal, Lipei Du +2
We study the dissipative evolution of (0+1)-dimensionally expanding media with Bjorken symmetry using the Boltzmann equation for massive particles in relaxation-time approximation.…
Characterizing the Functional Density Power Divergence Class
Souvik Ray, Subrata Pal, Sumit Kumar Kar +1
Divergence measures have a long association with statistical inference, machine learning and information theory. The density power divergence and related measures have produced man…
Characterizing Logarithmic Bregman Functions
Souvik Ray, Subrata Pal, Sumit Kumar Kar +1
Minimum divergence procedures based on the density power divergence and the logarithmic density power divergence have been extremely popular and successful in generating inference…
Finding quark content of neutron stars in light of GW170817
Rana Nandi, Subrata Pal
The detection of gravitational waves from GW170817 has provided a new opportunity to constrain the equation of state (EOS) of neutron stars. In this article, we investigate the pos…
