Influence of Disorder on Electron-Hole Pair Condensation in Graphene Bilayers
R. Bistritzer, A. H. MacDonald
Graphene bilayers can condense into a state with spontaneous interlayer phase coherence that supports dissipationless counterflow supercurrents. Here we address the influence of di…
Current-Induced Torques in Magnetic Metals: Beyond Spin Transfer
P. M. Haney, R. A. Duine, A. S. Nunez +1
Current-induced torques on ferromagnetic nanoparticles and on domain walls in ferromagnetic nanowires are normally understood in terms of transfer of conserved spin angular momentu…
Electronic correlations and disorder in transport through one-dimensional nanoparticle arrays
E. Bascones, V. Estevez, J. A. Trinidad +1
We analyze and clarify the transport properties of a one-dimensional metallic nanoparticle array with interaction between charges restricted to charges placed in the same conductor…
Graphene: A Pseudochiral Fermi Liquid
Marco Polini, Reza Asgari, Yafis Barlas +2
Doped graphene sheets are pseudochiral two-dimensional Fermi liquids with abnormal electron-electron interaction physics. We address graphene's Fermi liquid properties quantitative…
Ab-initio GMR and current-induced torques in Au/Cr multilayers
P. M. Haney, D. Waldron, R. A. Duine +3
We report on an {\em ab-initio} study of giant magnetoresistance (GMR) and current-induced-torques (CITs) in Cr/Au multilayers that is based on non-equilibrium Green's functions an…
Current Induced Order Parameter Dynamics: Microscopic Theory Applied to Co/Cu/Co spin valves
P. M. Haney, D. Waldron, R. A. Duine +3
Transport currents can alter alter order parameter dynamics and change steady states in superconductors, in ferromagnets, and in hybrid systems. In this article we present a scheme…
