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…
Critical Dynamics of the Anderson Transition on Small-World Graphs
Weitao Chen, Ignacio García-Mata, John Martin +3
The Anderson transition on random graphs draws interest through its resemblance to the many-body localization (MBL) transition with similarly debated properties. In this Letter, we…
Enhancing Quantum Metrology by Quantum Resonance Dynamics
Zhixing Zou, Jiangbin Gong, Weitao Chen
Quantum effects in metrology can in principle enhance measurement precision from the so-called standard quantum limit to the Heisenberg Limit. Further advancements in quantum metro…
Describing the critical behavior of the Anderson transition in infinite dimension by random-matrix ensembles: logarithmic multifractality and critical localization
Weitao Chen, Olivier Giraud, Jiangbin Gong +1
Due to their analytical tractability, random matrix ensembles serve as robust platforms for exploring exotic phenomena in systems that are computationally demanding. Building on a…
Quantum logarithmic multifractality
Weitao Chen, Olivier Giraud, Jiangbin Gong +1
Through a combination of rigorous analytical derivations and extensive numerical simulations, this work reports an exotic multifractal behavior, dubbed "logarithmic multifractality…
