Dyson expansion for form-bounded perturbations and applications to the polaron problem
Davide Desio, Robert Seiringer
We present an abstract Dyson expansion for perturbations that are merely relatively form-bounded, and apply it to the polaron problem. For a large class of polaron-type models, inc…

Two Comments on the Derivation of the Time-Dependent Hartree-Fock Equation
Niels Benedikter, Davide Desio
We revisit the derivation of the time-dependent Hartree-Fock equation for interacting fermions in a regime coupling a mean-field and a semiclassical scaling, contributing two comme…
