Analysis of the Disorder-Induced Zero Bias Anomaly in the Anderson-Hubbard Model
Hong-Yi Chen, R. Wortis, W. A. Atkinson
Using a combination of numerical and analytical calculations, we study the disorder-induced zero bias anomaly (ZBA) in the density of states of strongly-correlated systems modeled…

Generalized Inverse Participation Ratio as a Possible Measure of Localization for Interacting Systems
N. C. Murphy, R. Wortis, W. A. Atkinson
We test the usefulness of a generalized inverse participation ratio (GIPR) as a measure of Anderson localization. The GIPR differs from the usual inverse participation ratio in tha…

Physical mechanism for a kinetic energy driven zero-bias anomaly in the Anderson-Hubbard model
R. Wortis, W. A. Atkinson
The combined effects of strong disorder, strong correlations and hopping in the Anderson-Hubbard model have been shown to produce a zero bias anomaly which has an energy scale prop…
