Relativistic laser pulse dynamics in dense quantum plasma by QED approach

Author(s):

Punit Kumar

Abstract:

Utilizing the covariant Lagrangian function and Euler-Lagrange equation, a set of Dirac equations has been derived to elucidate the interaction between strong electromagnetic waves and spin-polarized plasmas. Analysis reveals that relativistic effects significantly impact the interaction process, manifesting through three key factors: self-energy, vacuum polarization, and radiation reaction. In this specific research paper, a quantum electrodynamical approach has been employed to formulate a set of relativistic kinetic equations accommodating both spin +1/2 and -1/2 particles. The model explicitly incorporates quantum electrodynamical characteristics within defined energy ranges and considers the effects influenced by particle spin. Employing this model, investigations into the interaction of lasers with electric fields of varying amplitudes have yielded valuable insights into this dynamic phenomenon.
