Séminaire du LPTMS: Shuang Wu

Thouless bandwidth formula in the Hofstadter model Shuang Wu (LPTMS, Université Paris-Sud) I will show a method of D. J. Thouless to calculate the Hofstadter spectrum bandwidth in relation to the Catalan constant. And I will present how we generalize Thouless bandwidth formula to its n-th moment and obtain a closed expression in terms of …

Séminaire du LPTMS: Giulio Bertoli

Finite temperature disordered bosons in two dimensions Giulio Bertoli (LPTMS, Université Paris-Sud) In this talk, I will present a study of the phase transitions in a two dimensional weakly interacting Bose gas in a random potential at finite temperatures. It is possible to identify superfluid, normal fluid and insulator phases. The study of the effect …
