Turning qubit noise into an advantage: Automatic state preparation and long-time dynamics for impurity models on quantum computers
Corentin Bertrand, Pauline Besserve, Michel Ferrero +1
Noise is often regarded as a limitation of quantum computers. In this work, we show that in the dynamical mean field theory (DMFT) approach to strongly-correlated systems, it can a…

Algorithm for computing perturbation series of dynamical mean field theory
Corentin Bertrand, Michel Ferrero, Olivier Parcollet
We show how to use diagrammatic techniques to compute the weak-coupling perturbation series of the self-consistent solution to a Dynamical Mean Field Theory (DMFT) problem. This ap…

Luttinger surface dominance and Fermi liquid behaviour of topological Kondo insulators SmB and YbB
Andrea Blason, Ivan Pasqua, Michel Ferrero +1
Defying the traditional classification into metals and insulators, several materials simultaneously display metallic thermal properties and insulating electric behaviour, as if the…
