Baryon asymmetry from hypermagnetic helicity in dilaton hypercharge electromagnetism
Abstract The generation of the baryon asymmetry of the Universe (BAU) from the hypermagnetic helicity, the physical interpretation of which is given in terms of hypermagnetic knots, is studied in inflationary cosmology, taking into account the breaking of the conformal invariance of hypercharge electromagnetic fields through both a coupling with the dilaton and that with a pseudoscalar field. I...
متن کاملTime reversal in classical electromagnetism
Richard Feynman has claimed that anti-particles are nothing but particles ‘propagating backwards in time’; that time reversing a particle state always turns it into the corresponding anti-particle state. According to standard quantum field theory textbooks this is not so: time reversal does not turn particles into anti-particles. Feynman’s view is interesting because, in particular, it suggests...

متن کاملQuantum Theory and Time Asymmetry
The relation between quantum measurement and thermodynam-ically irreversible processes is investigated. The reduction of the state vector is fundamentally asymmetric in time and shows an observer-relatedness which may explain the double interpretation of the state vector as a representation of physical states as well as of information about them. The concept of relevance being used in all stati...
متن کاملNotes on time evolution and conservation laws in electromagnetism
The time evolution of Maxwell’s equations is governed by Ampere’s law ∇ ×H = ∂ ∂t (E + P) + J and Faraday’s Law −∇×E = ∂ ∂t (H+M) +K, where E and H are the electric and magnetic fields, P and M are the electric and magnetic polarization densities, and J and K are the electric and magnetic current densities, respectively. (Magnetic current is the flow of magnetic charge, which is experimentally ...
