Description:
Explore the fascinating world of Quark-Gluon Plasma (QGP) in this comprehensive lecture by Rajeev Bhalerao. Delve into the properties of this extreme state of matter, which existed in the early universe and is now recreated in major collider experiments. Learn about the various stages of ultrarelativistic nucleus-nucleus collisions, from initial geometry fluctuations to hydrodynamic evolution. Discover the importance of anisotropic flow, the concept of hydrodynamic attractors, and the parallels between the Big Bang and the "Little Bang" in heavy-ion collisions. Gain insights into lattice QCD results, fluid dynamics principles, and recent developments in relativistic hydrodynamics. This in-depth presentation covers fundamental questions, experimental data, simulation techniques, and open challenges in understanding QGP, providing a thorough overview of this cutting-edge field in theoretical physics.
