my question was to check if the self energy is a mass weighting the energy of the interaction of the particle with the around, like we find that nucleons are more heavy inside a nucleus than alone, free... like also Z/W bosons get heavy because they interact with Higgs bosons...
so unlike effective mass of charges inside a semiconductor, which simply take into account the "lasyness" of the particle to move, self energy is a real mass, caused by interaction with the around, which is real energy, thus mass? am I wrong (it is basic QP I suppose, but I'm just below this level) so the heavy electrons are in fact really heavy pseudoparticle. pseudo because they are bound to a lattice, and probably tied with SPP? is this like nucleons are tied inside a nucleus, by strong force? this is the secret? when one of that electrons should move because of a force/field, it move slowly because first when moving he always exchange bosons with neighbours, which slow him. also because the energy have a weight? (or is it the same fact, self interaction slow by interaction, which is same a weight) 2012/1/6 Daniel Rocha <danieldi...@gmail.com> > The difference is not subtle, but it's the fault WL papers are not clear > because they are dealing simultaneously with different subjects where the > term "mass" has different meanings.
