Absolutely Continuous Spectrum for Random Schroedinger Operators on the Bethe Strip
The Bethe Strip of width m is the cartesian product B × {1, . . . , m}, where B is the Bethe lattice (Cayley tree). We prove that Anderson models on the Bethe strip have “extended states” for small disorder. More precisely, we consider Anderson-like Hamiltonians Hλ = 1/2∆⊗1+ 1⊗A + λV on a Bethe stri...
