Connecting finite-size scaling and renormalization-group flows in Anderson localization on random graphs
Ignacio García-Mata, Weitao Chen, John Martin +2
We investigate the relation between two complementary descriptions of the Anderson transition on small-world random graphs: finite-size scaling of eigenfunction moments and renorma…

Long-range Nonlinear Sigma Model for a Singular Quantum Kicked Rotor
Weitao Chen, Yunxiang Liao
Singular kicked rotors have long been compared with power-law random banded matrices (PRBM) because their momentum-space Floquet matrix elements decay algebraically. However, it ha…
