DOI: 10.1088/1751-8121/ab56e8
Abstract: We study the Anderson model on the Bethe lattice by working directly with propagators at real energies E. We introduce a novel criterion for the localization–delocalization transition based on the stability of the population of… read more here.

DOI: 10.1142/s0217984921500792
Abstract: A triple mixed-spin Ising system defined on the Bethe lattice is numerically investigated by means of exact recursion relations (ERRs) calculations. The lattice is constituted by three types of magnetic atoms A, B, C with… read more here.
