Chiral Decomposition in the Electronic Structure of Graphene Multilayers
Hongki Min, A. H. MacDonald
We show that the low-energy electronic structure of arbitrarily stacked graphene multilayers with nearest-neighbor interlayer tunneling consists of chiral pseudospin doublets. Alth…
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…
Effect of the long-range interaction in transport through one-dimensional nanoparticle arrays
E. Bascones, J. A. Trinidad, V. Estevez +1
We analyze the effect of the long-range interaction on the transport properties through ordered and disordered one-dimensional metallic nanoparticle arrays. We discuss how the thre…
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…
The Role of Electron-electron Interactions in Graphene ARPES Spectra
Marco Polini, Reza Asgari, Giovanni Borghi +3
We report on a theoretical study of the influence of electron-electron interactions on ARPES spectra in graphene that is based on the random-phase-approximation and on graphene's m…
Theory of the Pseudospin Resonance in Semiconductor Bilayers
Saeed H. Abedinpour, Marco Polini, A. H. MacDonald +3
The pseudospin degree of freedom in a semiconductor bilayer gives rise to a collective mode analogous to the ferromagnetic resonance mode of a ferromagnet. We present a theory of t…
