Effects of Strong Correlations on the Zero Bias Anomaly in the Extended Hubbard Model with Disorder
Yun Song, S. Bulut, R. Wortis +1
We study the effect of strong correlations on the zero bias anomaly (ZBA) in disordered interacting systems. We focus on the two-dimensional extended Anderson-Hubbard model, which…
The geometrically-averaged density of states calculated from the local Green's function as a measure of localization
R. Wortis, Yun Song, W. A. Atkinson
With the goal of measuring localization in disordered interacting systems, we examine the finite-size scaling of the geometrically-averaged density of states calculated from the lo…
Two-orbital Systems with Crystal Field Splitting and Interorbital Hopping
Yun Song, Liang-Jian Zou
The nondegenerate two-orbital Hubbard model is studied within the dynamic mean-field theory to reveal the influence of two important factors, i.e. crystal field splitting and inter…
The geometrically-averaged density of states as a measure of localization
Yun Song, W. A. Atkinson, R. Wortis
Motivated by current interest in disordered systems of interacting electrons, the effectiveness of the geometrically averaged density of states, , as an order parameter for…
Effects of interorbital hopping on orbital fluctuations and metal-insulator transitions: Extended linearized dynamical mean-field theory
Yun Song, Liang-Jian Zou
We study the effects of interorbital hopping on orbital fluctuations and Mott-Hubbard metal-insulator transition (MIT) in the two-orbital Hubbard model within the extended lineariz…
The effects of Zn Impurity on the Properties of Doped Cuprates in the Normal State
Yun Song
We study the interplay of quantum impurity, and collective spinon and holon dynamics in Zn doped high-T cuprates in the normal state. The two-dimensional t-t-J model…
