The renormalization flow of the hierarchical Anderson model at weak disorder
F. L. Metz, L. Leuzzi, G. Parisi
We study the flow of the renormalized model parameters obtained from a sequence of simple transformations of the 1D Anderson model with long-range hierarchical hopping. Combining n…
Transition between localized and extended states in the hierarchical Anderson model
F. L. Metz, L. Leuzzi, G. Parisi +1
We present strong numerical evidence for the existence of a localization-delocalization transition in the eigenstates of the 1-D Anderson model with long-range hierarchical hopping…
Imry-Ma criterion for long-range random field Ising model: short-/long-range equivalence in a field
Luca Leuzzi, Giorgio Parisi
The Ising model in a random field and with power-law decaying ferromagnetic bonds is studied at zero temperature. Comparing the scaling of the energy contributions of the ferromagn…
Renormalization Group on hierarchical lattices in finite dimensional disordered Ising and Blume-Emery-Griffiths Models
F. Antenucci, A. Crisanti, L. Leuzzi
Renormalization group on hierarchical lattices is often considered a valuable tool to understand the critical behavior of more complicated statistical mechanical models. In presenc…
Exactly solvable spin-glass models with ferromagnetic couplings: the spherical multi--spin model in a self-induced field
Andrea Crisanti, Luca Leuzzi
We report some results on the quenched disordered Spherical multi--Spin Model in presence of ferromagnetic couplings. In particular, we present the phase diagrams of some repres…
