self-energy

[¦self ′en·ər·jē]
(physics)
Classically, the contribution to the energy of a particle that arises from the interaction between different parts of the particle.
In a quantized field theory, the contribution to the energy of a particle due to virtual emission and absorption of other particles, in particular, mesons and photons.

This physical effect due to scattering of transport electrons can be incorporated in the self energy phenomenologically [44, 45], or in a stochastic fashion [46].
One class makes use of phenomenological expressions for the electronic self energy and the electronic spin susceptibility [5-9, 161, 162].
The total weight of the self energy corrections is bounded by the weight of the residual source operator [delta]J(i).
The calculation of the self energy [summation](k, [omega]) requires the calculation of the higher-order propagator B(k, [omega]) [cf.
It is worth noting that, up to this point, the system of equations for the Green's function and the anomalous self energy is similar to the one derived in the two-particle self consistent approach (TPSC) [86, 87, 160], the DMFT + [summation] approach [163-167], and a Mori-like approach by Plakida and coworkers [6, 7, 9].
To compute the Lamb shift let us then consider the one-loop photon self energy (113).
By observing the motions of the earth-moon (massive bodies) system over time, this "most-cost-effective" NASA experiment, amongst many other things, verified that gravitational self energy falls at the same rate as ordinary matter [35, 36].
