In the direct action form of classical EM we give the equation of motion for a classical massless bare charge without self-interaction in the presence of an external field. That equation permits superluminal speeds and time-reversals, and so is a realization of the Stueckelberg-Feynman view of electrons and positrons as different segments of a single trajectory. We give a particular solution to...

We compute the vacuum local modular Hamiltonian associated with a space ball region in free scalar massless Quantum Field Theory. give an explicit expression on one particle Hilbert terms of higher dimensional Legendre differential operator. The quadratic form is expressed integral energy density parabolic distribution. then get formula for entropy wave packet. This gives relative coherent stat...

Free fields of massless particles transforming covariantly under the Poincare group are constructed. The allowed infinite and finite dimensional representations of the Lorentz group are obtained. The wave functions are calculated in these representations in various bases u The commutation rules are computed, and turn out to be non-local for any infinite dimens ional fields. The transformation l...

Duality arguments suggest the existence of massless magnetic monopoles in gauge theories with the symmetry broken to a non-Abelian subgroup. I discuss how these arise and show how they are manifested as clouds of massless fields surrounding massive monopoles. The dynamics of these clouds is discussed, and the scattering of massless monopole clouds and massive monopoles is described.
