Plasma physics
  • 1. Plasma physics is a branch of physics that studies the behavior of ionized gases, known as plasmas. Plasmas are considered the fourth state of matter, alongside solids, liquids, and gases. They are composed of charged particles that exhibit collective behavior, such as electromagnetic interactions and self-organization. Plasma physics plays a crucial role in understanding phenomena such as fusion energy, astrophysical processes, and space environments. Researchers in this field study plasma properties, interactions, and applications in fields ranging from fusion research to semiconductor manufacturing.
