Localization Transition on Random Graphs with Chiral and Bogoliubov-de Gennes Symmetry Classes
Daniil Kochergin
We studied single-particle Anderson localization in ensembles of graphs that correspond to chiral and Bogoliubov-de Gennes (BdG) symmetry classes. For a random biregular bipartite…

Localization transition in non-Hermitian systems depending on reciprocity and hopping asymmetry
Daniil Kochergin, Vasilii Tiselko, Arsenii Onuchin
We studied the single-particle Anderson localization problem for non-Hermitian systems on directed graphs. Random regular graph and various undirected standard random graph models…

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…
