DESCRIPTION:Title: Quantum Ising model with additional all-to-all interacti
 ons.\n\nAbstract: I will consider the quantum Ising model with additional 
 all-to-all interactions\, which serves as a toy model for long-range inter
 actions and that arises in different contexts. I will in a first part show
  the mean-field solvability of the model\, which holds despite the coexist
 ence of short-range and long-range interactions. In a second part I will d
 iscuss the unusual behaviour of the splitting between the two degenerate g
 round states in presence of interactions corresponding to power-laws with 
 exponent smaller than 1.\n\nSeminar Physique Mathématique\n	Hybride\, Pav.
