Carissime/i,
mercoledì, dopo la nostra lezione, in aula A del dipartimento si terrà il seminario del dott. Lorenzo di Pietro, che sarà a breve docente della nostra università (e potrebbe interessare qualcuno di voi per un'eventuale tesi di laurea!). Vi consiglio la partecipazione ;)
Il seminario si terrà Mercoledì 29 Maggio, alle 16:00 in Aula A del dipartimento di Fisica.Titolo: Abelian gauge theories in 3dAbstract: Abelian gauge theories in 3d are interesting laboratories to study the strongly-coupled dynamics of quantum field theory. After reviewing some long-standing questions about their behavior in the IR, and some exciting new developments, I will describe two different approaches to estimate their observables at the critical point. The first one is the epsilon-expansion, based on the existence of a Wilson-Fisher-like fixed point for the theory continued to d = 4 - epsilon. The second one is based on a realization of these theories as boundary conditions for a a four-dimensional Maxwell field.
