Analytic results for the Anderson Impurity Model
Vassilis Pandis, Alex C. Hewson
In the Renormalised Perturbation Theory (RPT) the Anderson impurity model is interpreted in terms of renormalised parameters …

Renormalized perturbation theory flow equations for the Anderson impurity model
Vassilis Pandis
We apply the renormalized perturbation theory (RPT) to the symmetric Anderson impurity model. Within the RPT framework exact results for physical observables such as the spin and c…

Numerical integration of discontinuous functions in many dimensions
Vassilis Pandis
We consider the problem of numerically integrating functions with hyperplane discontinuities over the entire Euclidean space in many dimensions. We describe a simple process throug…
