Explore the phenomenon of collectivity in electron-ion collisions at the Electron-Ion Collider (EIC) in this 25-minute lecture by Md. Nasim. Delve into the physics of e+A (electron-nucleus) interactions and their collective behavior, which is crucial for understanding nuclear structure and dynamics at high energies. Learn about the experimental techniques and theoretical frameworks used to study these collisions, and discover how the EIC's unique capabilities will advance our knowledge of quark-gluon plasma formation and the emergence of collective phenomena in nuclear matter. Gain insights into the implications of these studies for our understanding of fundamental nuclear and particle physics, as well as the early universe.
