Monte-Carlo phase diagram of a Hubbard-Peierls model in the search for spin crossover transition in -conjugated polymers
S. Bhattacharya, M. S. Ferreira, S. Sanvito
We present a Monte Carlo study of the finite temperature properties of an extended Hubbard-Peierls model describing one dimensional -conjugated polymers. The model incorporates…
Graphene-based spin-pumping transistor
F. S. M. Guimarães, A. T. Costa, R. B. Muniz +1
We demonstrate with a fully quantum-mechanical approach that graphene can function as gate-controllable transistors for pumped spin currents, i.e., a stream of angular momentum ind…
Carbon nanotube: a low-loss spin-current waveguide
F. S. M. Guimarães, D. F. Kirwan, A. T. Costa +3
We demonstrate with a quantum-mechanical approach that carbon nanotubes are excellent spin-current waveguides and are able to carry information stored in a precessing magnetic mome…
