Title: Monopoles and Baryons from Sphalerons and Instantons

Abstract: I will discuss non-perturbative quantum field theory phenomena in the
Standard Model of particle physics and its extensions, described by
semiclassical sphaleron and instanton solutions. In the Standard
Model, they violate baryon number and therefore play an important role
in the question of the baryon asymmetry of the Universe. I show that
the process is enhanced in a magnetic field, which can have
cosmological implications and may even make it possible to achieve
baryon number violation in laboratory in distant future. In theories
with magnetic monopoles, the presence of a magnetic field leads to
monopole pair production, with implications for neutron stars and
terrestrial monopole search experiments.
