  1. 34. Anomalous dimensions without Feynman diagrams from Conformal symmetry of Wilson-Fisher fixed points
    Ferdinando Gliozzi (Torino University)
    13/12/2017, 11:30
    We compute, to the first non-trivial order in the epsilon expansion, the anomalous dimensions of an infinite class of local operators, including the partially conserved higher spin currents, using only constraints from conformal symmetry. According to the bootstrap philosophy, no reference is made to any Lagrangian, equations of motion or coupling constants.

  2. 42. Plastic flow and stochastic resonance in soft glassy materials
    Dr Andrea Scagliarini (IAC-CNR)
    13/12/2017, 12:00
    Flow in soft-glasses occurs via a sequence of reversible elastic deformations and local irreversible plastic rearrangements. Yield events in the material cause kicks adding up to an effective thermal noise, an intuition that has inspired the development of phenomenological models aiming at explaining the main features of soft-glassy rheology. We provide a specific scenario for such...

  3. 69. Exact results for quenched disorder at criticality
    Gesualdo Delfino (TS)
    13/12/2017, 12:20
    We show how an exact field theoretical replica method can be formulated for the study of two-dimensional systems with quenched disorder at criticality. For the q-state Potts model we obtain a solution which appears to solve longstanding theoretical and numerical puzzles about the disordered ferromagnet. The space of solutions with Potts permutational symmetry also accounts for strong...

  4. 51. Strong interaction in background magnetic fields
    Andrea Rucci (University of Pisa and INFN Pisa)
    13/12/2017, 12:40
    I will present some recent results obtained in our on-going effort devoted to the study of the influence of strong external magnetic fields on the heavy quark-antiquark interaction. These fields, expected to be created in physical situations such as heavy-ion collisions, may induce relevant modifications of the properties of the strong force. In particular, in this talk I will focus both on...
