Electro-Magnetic Waves within a Model for Charged Solitons
We analyze the model of topological fermions (MTF), where charged fermions
are treated as soliton solutions of the field equations. In the region far from
the sources we find plane waves solutions with the properties of
electro-magnetic waves.Comment: 4 pages, 2 figure
Two-photon exchange and elastic scattering of longitudinally polarized electron on polarized deuteron
Structure functions and polarization observables in elastic scattering of
longitudinally polarized electron on polarized deuteron are considered within
approximation of one-photon + two-photon exchange. It is shown that
contribution of two-photon exchange in the generalized structure function A is
of order of few percent, while in the generalized structure function B it is of
order of 10--20 %. We have found that components T_{20} and T_{21} of tensor
analyzing power are mainly determined by one-photon exchange, but T_{22} is
mainly determined by interference between one-photon exchange and two-photon
exchange. We have also considered polarization observables T_{11}, C_{21} and
C_{22} which are proportional to imaginary part of the reaction amplitude and
vanish in the framework of one-photon exchange.Comment: 6 pages, 8 figure
Electrodynamic Limit in a Model for Charged Solitons
We consider a model of topological solitons where charged particles have
finite mass and the electric charge is quantised already at the classical
level. In the electrodynamic limit, which physically corresponds to
electrodynamics of solitons of zero size, the Lagrangian of this model has two
degrees of freedom only and reduces to the Lagrangian of the Maxwell field in
dual representation. We derive the equations of motion and discuss their
relations with Maxwell's equations. It is shown that Coulomb and Lorentz forces
are a consequence of topology. Further, we relate the U(1) gauge invariance of
electrodynamics to the geometry of the soliton field, give a general relation
for the derivation of the soliton field from the field strength tensor in
electrodynamics and use this relation to express homogeneous electric fields in
terms of the soliton field.Comment: 13 pages, 4 figures, Introduction and Section II (Model Lagrangian)
