Phase diagram of a pseudogap Anderson model with application to graphene
Hung T. Dang, Hoa T. M. Nghiem
The Anderson model of an -wave single-orbital correlated impurity placed on a noninteracting honeycomb lattice, a simplified model for studying an impurity on graphene, is used…
Time-dependent spectral functions of the Anderson impurity model in response to a quench with application to time-resolved photoemission spectroscopy
H. T. M. Nghiem, H. T. Dang, T. A. Costi
We investigate several definitions of the time-dependent spectral function of the Anderson impurity model following a quench and within the time-dependent numerical renorm…
Correlation length in a generalized two-dimensional XY model
Duong Xuan Nui, Le Tuan, Nguyen Duc Trung Kien +3
The measurements of the magnetic and nematic correlation lengths in a generalization of the two dimensional XY model on the square lattice are presented using classical Monte Carlo…
Ferromagnetism and correlation strength in cubic barium ruthenate in comparison to strontium and calcium ruthenate: a dynamical mean field study
Qiang Han, Hung T. Dang, A. J. Millis
We present density functional plus dynamical mean field studies of cubic BaRuO using interaction parameters previously found to be appropriate for the related materials CaRuO$_…
Strong correlation effects in theoretical STM studies of magnetic adatoms
Hung T. Dang, Manuel dos Santos Dias, Ansgar Liebsch +1
We present a theoretical study for the scanning tunneling microscopy (STM) spectra of surface-supported magnetic nanostructures, incorporating strong correlation effects. As concre…
Electronic correlations, magnetism and Hund's rule coupling in the ruthenium perovskites SrRuO and CaRuO
Hung T. Dang, Jernej Mravlje, Antoine Georges +1
A comparative density functional plus dynamical mean field theory study of the pseudocubic ruthenate materials CaRuO and SrRuO is presented. Phase diagrams are determined f…
