salle de séminaire 3ème étage Bâtiment 3r1 Université Toulouse III, Toulouse

Ilya Gruzberg (Université d’État de l’Ohio, États-Unis) Summary : Anderson transitions (ATs) between metals and insulators or between topologically distinct insulators, share common features with conventional second-order phase transitions, such as the critical point of the Ising model for a magnet. However, ATs also exhibit many unusual features including the multifractal scaling of the critical… Read More »Anderson transitions and (lost) conformal invariance – (Ilya Gruzberg / Seminar / LPT). – 11/10/2022

Brève histoire de l’intrication quantique depuis Euler – (Grzegorz Rajchel-Mieldzioć / Seminar / LPT). – 22/11/2022

Grzegorz Rajchel-Mieldzioć (ICFO Barcelone) The negative solution to the famous problem of 36 officers of Euler implies that there are no two orthogonal Latin squares of order six. We show that the problem has a solution, provided the officers can be entangled and construct two quantum orthogonal Latin squares of this size. In other words,… Read More »Brève histoire de l’intrication quantique depuis Euler – (Grzegorz Rajchel-Mieldzioć / Seminar / LPT). – 22/11/2022
