Theory of damping in magnetization dynamics, dispelling a myth and pointing a way forward

D. M. Edwards

There is a widely-held belief amongst theoreticians that the Gilbert damping parameter α in magnetization dynamics is infinite for a pure metal at T=0. The basic error leading to t…

The absence of intraband scattering in a consistent theory of Gilbert damping in metallic ferromagnets

D. M. Edwards

Damping of magnetization dynamics in a ferromagnetic metal is usually characterized by the Gilbert parameter alpha. Recent calculations of this quantity, using a formula due to Kam…

A smooth polaron-molecule crossover in a Fermi system

D M Edwards

The problem of a single down spin particle interacting with a Fermi sea of up spin particles is of current interest in the field of cold atoms. The Hubbard model, appropriate to at…

A Green's function decoupling scheme for the Edwards fermion-boson model

D M Edwards, S Ejima, A Alvermann +1

Holes in a Mott insulator are represented by spinless fermions in the fermion-boson model introduced by Edwards. Although the physically interesting regime is for low to moderate f…

Emergence of local magnetic moments in doped graphene-related materials

P. Venezuela, R. B. Muniz, A. T. Costa +3

Motivated by recent studies reporting the formation of localized magnetic moments in doped graphene, we investigate the energetic cost for spin polarizing isolated impurities embed…

Analytical calculation of the Green's function and Drude weight for a correlated fermion-boson system

A Alvermann, D M Edwards, H Fehske

In classical Drude theory the conductivity is determined by the mass of the propagating particles and the mean free path between two scattering events. For a quantum particle this…
