DESCRIPTION:We know how electrons behave in 1,2,3 dimensions, but what about d=1.58? In this talk, I will first describe fractals, structures that may have a non-integer dimension. Then I will present experiments on electronic [1] and photonic [2] quantum simulators and explain how electrons and photons behave at fractal dimension. Finally, I will discuss the fractal Hubbard model and tell you a bit about Dionys Baeriswyl, a friend and mentor who gave me the first insights on the Hubbard Model. \n \n[1] S.N. Kempkes, M.R.
