Axil, First, if you use paragraphs, your posts will be much more readable.
Second, your URL link is broken. The new one is - "Structure Enhancement Factor Relationships in Single Gold Nanoantennas.." http://sites.weinberg.northwestern.edu/vanduyne/files/2013/01/2012_Kleinman_2.pdf A good, even if difficult to read, paper. The momentum "superkick" example I cited already includes the momentum a charged particle acquires at an optical vortex. As you note, the high local E-field can be enormous when amplified. It would be good to know how much momentum a charged particle can acquire in such a field. This is the calculation, I am interested in: Assume a static electrical field = E[V/m] lasting a duration time = T Then if two oppositely charged particles, with charges -e and +e (e = electron charge) and masses m and M, collide head-on both acquire equal, opposite impulses, or momentum kicks = TE/e The kinetic energy TE/e represents depends on m and M. (It can be waveform squeezing, as well as linear displacement speed. The transient colliding composite particle can have zero velocity.) So what amplitudes and durations must an e-m wave crest have to give charged particles kinetic energies sufficient to reach LENR levels? - e.g., for electron capture, pair-creation, etc. - And, perhaps it's worth noting that electron, protons, some nuclei are spin-1/2 fermions, so the Dirac equation, instead of the Schrodinger equation sometimes applies. This could involve the 'Klein paradox'.
