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 polygamma, zeta and Euler numbers.
