Power-law banded random matrices: a testing ground for the Anderson transition

In this talk we present numerical simulations using the Power-law band random matrix (PRBM) ensemble which became a useful testing tool for investigation of the bahavior of random systems at the Anderson transition. The effect of multifractality of the eigenstates in several physical situations are investigated, e.g. interaction at the Hartree-Fock level, entanglement, dynamics of wavepackets, magnetic impurities, etc.
