Aspects of quantum dynamics in magnets

We investigate the quantum dynamics of a pair of magnetic grains and of a ferromagnetic domain wall in presence of both a Caldeira-Leggett type of environment and of nuclear spins, from which we consider the "degeneracy blocking" effect. For the grains, we find that dissipation is extre...
