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…

Time-dependent numerical renormalization group method for multiple quenches: towards exact results for the long time limit of thermodynamic observables and spectral functions
H. T. M. Nghiem, T. A. Costi
We develop an alternative time-dependent numerical renormalization group (TDNRG) formalism for multiple quenches and implement it to study the response of a quantum impurity system…
