Expanding on the concept of the authors' previous book "Electroweak
Processes in External Electromagnetic Fields," this new book
systematically describes the investigation methods for the effects of
external active media, both strong electromagnetic fields and hot dense
plasma, in quantum processes. Solving the solar neutrino puzzle in a
unique experiment conducted with the help of the heavy-water detector at
the Sudbery Neutrino Observatory, along with another neutrino
experiments, brings to the fore electroweak physics in an active
external medium. It is effectively demonstrated that processes of
neutrino interactions with active media of astrophysical objects may
lead, under some physical conditions, to such interesting effects as
neutrino-driven shockwave revival in a supernova explosion, a "cherry
stone shooting" mechanism for pulsar natal kick, and a neutrino pulsar.
It is also shown how poor estimates of particle dispersion in external
active media sometimes lead to confusion. The book will appeal to
graduate and post-graduate students of theoretical physics with a prior
understanding of Quantum Field Theory (QFT) and the Standard Model of
Electroweak Interactions, as well as to specialists in QFT who want to
know more about the problems of quantum phenomena in hot dense plasma
and external electromagnetic fields.
