Disorder Induced Localized States in Graphene
Vitor M. Pereira, F. Guinea, J. M. B. Lopes dos Santos +2
We consider the electronic structure near vacancies in the half-filled honeycomb lattice. It is shown that vacancies induce the formation of localized states. When particle-hole sy…
The Double Exchange Model at Low Densities
Vitor M. Pereira, J. M. B. Lopes dos Santos, A. H. Castro Neto
We obtain the phase diagram of the double-exchange model at low electronic densities in the presence of electron-electron interactions. The single particle problem and its extensio…
The Magnetism of Li doped LaCuO: the antiferromagnetic spin-shard state
O. P. Sushkov, A. H. Castro Neto
We study the dynamics of a single hole in Li and Sr doped LaCuO and its extension to a finite hole concentration. We compare the physics of LaSrCuO and La…
Frustration of Decoherence in Open Quantum Systems
E. Novais, A. H. Castro Neto, L. Borda +2
We study a model of frustration of decoherence in an open quantum system. Contrary to other dissipative ohmic impurity models, such as the Kondo model or the dissipative two-level…
