Self energy electrostatics
In quantum field theory, the energy that a particle has as a result of changes that it causes in its environment defines self-energy $${\displaystyle \Sigma }$$, and represents the contribution to the particle's energy, or effective mass, due to interactions between the particle and its environment. In … See more Mathematically, this energy is equal to the so-called on mass shell value of the proper self-energy operator (or proper mass operator) in the momentum-energy representation (more precisely, to $${\displaystyle \hbar }$$ See more In chemistry, the self-energy or Born energy of an ion is the energy associated with the field of the ion itself. In solid state and condensed-matter physics self-energies and a … See more • Quantum field theory • QED vacuum • Renormalization • Self-force See more WebKnowing the exact form of the Coulomb self-energy of a uniformly charged rectangular plate as a function of length/width and shape parameters may help one analyze how electrostatic energy is stored in various uniformly charged plates with rectangular shapes without resorting to approximations.
