SUMMARY:Séminaire du LPTMS: Giacomo Gradenigo - LPTMS\, salle 201\, 2ème 
 étage\, Bât 100\, Campus d'Orsay - 21 Oct 14 11:00
DESCRIPTION:Glassy properties of a XOR-SAT model in finite dimensions\nGiac
 omo Gradenigo\, LPTMS\nTwo competing scenarios have been proposed since a 
 long time as alternative to explain the critical slowing down of glass-for
 ming materials:  the dynamic facilitation scenario\, well represented by 
 kinetically constrained models (KCM)\, where glassiness arise just as a dy
 namical phenomenon\, and the thermodynamic scenario of the Random First-Or
 der Transition (RFOT) theory\, according to which the slowing down of dyna
 mics is the signature of a true thermodynamic transition\, the glass trans
 ition.\nIn this talk I will review and discuss some properties of a finite
  dimensional XOR-SAT model\, the triangular plaquette model\, which is a t
 ypical example of kinetically constrained model. In particular I will expl
 ain the mechanism by which the addition of an arbitrarily small  perturba
 tion in the Hamiltonian of this system may induce a finite temperature gla
 ss transition. I discuss therefore how the model studied\, just by tuning 
 a parameter\, can be either representative of the dynamic facilitation sce
 nario or of the thermodynamic one: this result suggest that the two scenar
 ios should be regarded not as alternative but just as two complementary wa
 ys to explain the same kind of phenomenology.
