Level curvature distribution: from bulk to the soft edge of random Hermitian matrices
Yan V Fyodorov
Level curvature is a measure of sensitivity of energy levels of a disordered/chaotic system to perturbations. In the bulk of the spectrum Random Matrix Theory predicts the probabil…

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…
