About Us

Our Group works on phase transitions in the early universe and their manifestations in relativistic heavy ion collisions. We study topological defects like cosmic strings, domain walls and their motion through the early universe plasma. The tools we use are based on magnetohydrodynamics (MHD). We explore possible observational signatures of stable topological defects. We also explore the generation and evolution of the magnetic fields in the early universe. Features of the quark hadron transition in the early universe can also be understood from the relativistic heavy ion collision experiments currently being done. We are currently developing Machine Learning methods to use the experimental data to understand some of the key aspects of the Quark Hadron Phase transition.
