Robust extended states in Anderson model on partially disordered random regular graphs
Daniil Kochergin, Ivan M. Khaymovich, Olga Valba +1
In this work we analytically explain the origin of the mobility edge in the partially disordered random regular graphs of degree d, i.e., with a fraction of the sites being dis…

Anatomy of the fragmented Hilbert space: eigenvalue tunneling, quantum scars and localization in the perturbed random regular graph
Daniil Kochergin, Ivan M. Khaymovich, Olga Valba +1
We consider the properties of the random regular graph with node degree perturbed by chemical potentials for a number of short -cycles. We analyze both numerically and…
