Quick Reference

In classical physics the self-energy of a system is the contribution to the energy of the system resulting from the interaction between different parts of the system. In quantum field theory the self-energy of a particle is the contribution to the energy of the particle due to virtual emission and absorption of particles. In the many-body problem in quantum mechanics the self-energy Es of a particle is the difference EQEB, where EQ is the energy of the quasiparticle associated with the particle and EB is the energy of the ‘bare’ particle. The particle interacts with its surrounding medium, which in turn acts back on the original particle.
