Understand
We revisit the Anderson localization problem on Bethe lattices, putting in contact various aspects which have been previously only discussed separately.
- For the case of connectivity 3 we compute by the cavity method the density of states and the evolution of the mobility edge with disorder.
- Furthermore, we show that below a certain critical value of the disorder the smallest eigenvalue remains delocalized and separated by all the others (localized) ones by a gap.
- We also study the evolution of the mobility edge at the center of the band with the connectivity, and discuss the large connectivity limit.
