Robust universal relations in neutron star asteroseismology
Deepak Kumar, Tuhin Malik, Hiranmaya Mishra +1
The non-radial oscillations of the neutron stars (NSs) have been suggested as a useful tool to probe the composition of neutron star matter (NSM). With this scope in mind, we consi…
The causality and stability of relativistic spin-hydrodynamics
Golam Sarwar, Md Hasanujjaman, Jitesh R. Bhatt +2
We study the causality and stability of relativistic hydrodynamics with the inclusion of the spin degree of freedom as a hydrodynamic field. We consider two specific models of spin…
Diffusion matrix associated with the diffusion processes of multiple conserved charges in a hot and dense hadronic matter
Arpan Das, Hiranmaya Mishra, Ranjita K. Mohapatra
Bulk matter produced in heavy ion collisions has multiple conserved quantum numbers like baryon number, strangeness and electric charge. The diffusion process of these charges can…
Viscosity calculations from Hadron Resonance Gas model: Finite size effect
Snigdha Ghosh, Subhasis Samanta, Sabyasachi Ghosh +1
We have attempted to review on microscopic calculation of transport coefficients like shear and bulk viscosities in the framework of hadron resonance gas model, where a special att…
Impact of Magnetic field on neutron star properties
Tuhin Malik, Debashree Sen, T. K. Jha +1
We derive an equation of state for magnetized charge neutral nuclear matter relevant for neutron star structure. The calculations are performed within an effective chiral model bas…
Transport responses from rate of decay and scattering processes in the Nambu--Jona-Lasinio model
Sabyasachi Ghosh, Fernando E. Serna, Aman Abhishek +2
We have calculated quark and anti-quark relaxation time by considering different possible elastic and inelastic scatterings in the medium. Comparative role of these elastic and ine…
Estimating transport coefficients of interacting pion gas with K-matrix cross sections
Guruprasad Kadam, Swapnali Pawar, Hiranmaya Mishra
We estimate the transport coefficients, , shear and bulk viscosities as well as thermal and electrical conductivities, of hot pionic matter using relativistic Boltzmann equat…
Calculations of Shear, Bulk viscosities and Electrical conductivity in Polyakov-Quark-Meson model
Pracheta Singha, Aman Abhishek, Guru Kadam +2
We have evaluated the transport coefficients of quark and hadronic matter in the frame work of Polyakov-Quark-Meson model. The thermal widths of quarks and mesons, which inversely…
QCD sum rules for nucleon two-point function in nuclear medium
S. Mallik, Hiranmaya Mishra
We derive QCD sum rules from the nucleon two-point function in nuclear medium, calculating its specral function in chiral perturbation theory to one loop. Our calculation shows the…
Vacuum structure in QCD and Correlation functions
Hiranmaya Mishra
We discuss here a model of QCD vacuum in terms of quark antiquark and gluon condensates alongwith their fluctuations. The correlation functions of hadronic currents in such a vacuu…
Neutron matter - Quark matter phase transition and Quark star
H. Mishra, S. P. Misra, P. K. Panda +1
We consider the neutron matter quark matter phase transition along with possible existence of hybrid quark stars. The equation of state for neutron matter is obtained using a nonpe…
Hot Nuclear Matter : A Variational Approach
H. Mishra, S. P. Misra, P. K. Panda +1
We develop a nonperturbative technique in field theory to study properties of infinite nuclear matter at zero temperature as well as at finite temperatures. Here we dress the nucle…
