Level number variance and spectral compressibility in a critical two-dimensional random matrix model
A. Ossipov, I. Rushkin, E. Cuevas
We study level number variance in a two-dimensional random matrix model characterized by a power-law decay of the matrix elements. The amplitude of the decay is controlled by the p…

Universal and non-universal features of the multifractality exponents of critical wave-functions
I. Rushkin, A. Ossipov, Y. V. Fyodorov
We calculate perturbatively the multifractality spectrum of wave-functions in critical random matrix ensembles in the regime of weak multifractality. We show that in the leading or…

Criticality without self-similarity: a 2D system with random long-range hopping
A. Ossipov, I. Rushkin, E. Cuevas
We consider a simple model of quantum disorder in two dimensions, characterized by a long-range site-to-site hopping. The system undergoes a metal-insulator transition -- its eigen…
