Coherent forward scattering peak and multifractality

It has recently been shown that interference effects in disordered systems give rise to two non-trivial structures: the coherent backscattering (CBS) peak, a well-known signature of presence disorder, and forward scattering (CFS) which emerges when Anderson localization sets in. We study here CFS effect quantum multifractality, fundamental property several systems, such as model at metal-insulator transition. focus on Floquet find peak shape its height dynamics are generically controlled by multifractal dimensions $D_1$ $D_2$, spectral form factor. check our results using 1D system whose states have properties single parameter. Our predictions fully confirmed numerical simulations analytic perturbation expansions this model. results, we believe be generic, provide an original direct way detect characterize multifractality experimental systems.
