Terrà un seminario dal titolo: “Exchange and exclusion for non-abelian anyons”

*Abstract:*

Anyons are effective particles arising in certain 2D quantum systems and having properties intermediate to bosons and fermions. Roughly speaking, they may be defined by representing an exchange of coordinates of the many-body wave function by an arbitrary complex phase (abelian anyons) or, more generally, a unitary matrix (non-abelian anyons). I will give an introduction to anyons and discuss how to extend many-body methods of exchange and exclusion to the case of non-abelian anyons, focusing on two of the most popular such models: the Fibonacci and the Ising anyon models. This is joint work with Viktor Qvarfordt.

Tutti gli interessati sono invitati a partecipare.
