My research involves the development of relativistic dissipative hydrodynamic frameworks to describe different types of fluids. The aim is to use such theories to understand the evolution of the matter produced in relativistic heavy-ion collisions. Hydrodynamics being a macroscopic theory requires a microscopic theory to complete the description of the system. For this purpose I use the relativistic kinetic theory which has been proved to be a comparatively simple yet very useful microscopic theory.
The majority of my research has been focused on the derivation of relativistic dissipative hydrodynamics of spin-polarizable fluids made of spin-half particles (both with and without magnetic field). This work was motivated from the observation of spin-polarization of particles at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC). Through these works, the evolution mechanism of spin degrees of freedom of the system were understood for the first time. The evolution of spin was found to depend on gradients of various thermodynamical variables.
Furthermore, I developed the hydrodynamic description of a system of quasiparticle, a system with explicit pair production and annihilation processes and also a system of particles whose relaxation time depended on the particle's momentum.
These works were the fruits of successful collaborations with Dr. Amaresh Jaiswal, Prof. Wojciech Florkowski, Dr. Radoslaw Ryblewski, Dr. Vinod Chandra, Dr. Avdhesh Kumar, Dr. Manu Kurian, Sunil Jaiswal and Dipika Dash.
