We calculated the self-interaction force on a static electric charge near a dielectric sphere. Two regularization methods, Quinn-Wald and mode-sum, were used to manage the divergent bare force.

Area of Science:

  • Electromagnetism
  • Theoretical Physics

Background:

  • Understanding the self-interaction of charges is crucial in classical and quantum electrodynamics.
  • Dielectric materials modify electric fields, presenting unique challenges for force calculations.

Purpose of the Study:

  • To compute the self-interaction force on a free, static electric charge situated outside a uniform dielectric sphere.
  • To apply and compare two distinct regularization techniques for handling divergent forces.

Main Methods:

  • The Lorentz force law was directly applied to the electric field generated by the charge at its own location.
  • The Quinn-Wald comparison axiom was utilized as a regularization method.
  • Mode-sum regularization was employed as an alternative approach to handle divergent forces.

Main Results:

  • A finite self-interaction force was successfully computed for the electric charge.
  • Both the Quinn-Wald comparison axiom and mode-sum regularization yielded consistent results for the divergent force.

Conclusions:

  • The self-interaction force on a charge near a dielectric sphere can be regularized using established theoretical frameworks.
  • This work provides a method for calculating such forces, relevant for condensed matter physics and electrodynamics.
