Non-local correlation effects due to virtual spin-flip processes in itinerant electron ferromagnets
S. Paischer, G. Vignale, M. I. Katsnelson +2
We present an ab initio method for eletcronic structure calculations, which accounts for the interaction of electrons and magnons in ferromagnets. While it is based on a many body…
U(1)SU(2) Gauge Invariance Made Simple for Density Functional Approximations
S. Pittalis, G. Vignale, F. G. Eich
A semi-relativistic density-functional theory that includes spin-orbit couplings and Zeeman fields on equal footing with the electromagnetic potentials, is an appealing framework t…
Nonlocal Drag of Magnons in a Ferromagnetic Bilayer
Tianyu Liu, G. Vignale, M. E. Flatté
Quantized spin waves, or magnons, in a magnetic insulator are assumed to interact weakly with the surroundings, and to flow with little dissipation or drag, producing exceptionally…
Engineering Superfluidity in Electron-Hole Double Layers
Sergio Conti, Giovanni Vignale, A. H. MacDonald
We show that band-structure effects are likely to prevent superfluidity in semiconductor electron-hole double-layer systems. We suggest the possibility that superfluidity could be…
