Relatore: Miguel Ibanez de Berganza - CNR e Dipartimento di Fisica, Università di Roma "La Sapienza"Luogo: Aula FeynmanE-mail organizzatore: raffaella.burioni@fis.unipr.itAbstract:We will introduce the physics of interacting models in irregulartopologies (i.e., non-invariant under spatial symmetries), and exposerecent developments on the analysis of vector models with p=2 andp=4-body interactions.Algorithms for the efficient Monte-Carlo analysis of this kind of modelswill be discussed as well.
