PhD Degree in plasma physics - About Minimum Qualification, Universities, And Admission 2025-26
About This Course
Plasmas—the fourth state of matter—consist of freely moving charged particles such as ions and electrons. Unlike solids, liquids, or gases, plasmas display collective behaviors where phenomena such as waves, instabilities, and turbulence dominate system dynamics.
The scientific study of plasmas is inherently interdisciplinary, bringing together:
Classical and quantum mechanics
Electricity and magnetism
Fluid and hydrodynamics
Atomic and molecular physics
Applied mathematics
Statistical mechanics
Kinetic theory
These fields combine to form unique theoretical and experimental approaches, making plasma physics one of the most diverse and dynamic areas of modern science.
