This study unifies electromagnetic and fluid fields for relativistic charged fluids. It introduces a new prescription to derive plasma dynamics, highlighting temperature effects and exploring consequences.

Area of Science:

  • Plasma Physics
  • Relativistic Electrodynamics
  • Fluid Dynamics

Background:

  • Understanding the behavior of relativistic, hot charged fluids is crucial in various astrophysical and high-energy physics contexts.
  • Existing models often treat electromagnetic and fluid dynamics separately, limiting comprehensive analysis.

Purpose of the Study:

  • To develop a unified framework for describing the dynamics of relativistic, hot charged fluids.
  • To introduce a novel hybrid magnetofluid field that integrates electromagnetic and fluid properties.
  • To explore the implications of this unification for plasma physics.

Main Methods:

  • Formulation of a hybrid magnetofluid field by unifying the electromagnetic field with an analogous flow field.
  • Development of a well-defined prescription to derive plasma equations of motion from field-free equations.

    • A unified expression for the dynamics of relativistic, hot charged fluids is established.
    • The prescription successfully derives plasma equations of motion in electromagnetic fields from field-free equations.
    • The influence of plasma temperature on the dynamics is explicitly highlighted.

    Conclusions:

    • The proposed hybrid magnetofluid field offers a more comprehensive description of relativistic plasma dynamics.
    • This unification provides new insights into the interplay between electromagnetic fields and fluid motion in hot plasmas.
    • Further exploration of the consequences of this unification is warranted for advancing plasma physics research.
