Maximum entropy analytic continuation for frequency-dependent transport coefficients with non-positive spectral weight
A. Reymbaut, A. -M. Gagnon, D. Bergeron +1
The computation of transport coefficients, even in linear response, is a major challenge for theoretical methods that rely on analytic continuation of correlations functions obtain…

Impurity-induced magnetic moments on the graphene-lattice Hubbard model: an inhomogeneous cluster DMFT study
M. Charlebois, D. Sénéchal, A. -M. Gagnon +1
Defect-induced magnetic moments are at the center of the research effort on spintronic applications of graphene. Here we study the problem of a nonmagnetic impurity in graphene wit…
