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…
A Coulomb gas approach to the anisotropic one-dimensional Kondo lattice model at arbitrary filling
E. Novais, E. Miranda, A. H. Castro Neto +1
We establish a mapping of a general spin-fermion system in one dimension into a classical generalized Coulomb gas. This mapping allows a renormalization group treatment of the anis…
Droplets in Disordered Metallic Quantum Critical Systems
Antonio H. Castro Neto, Barbara A. Jones
We present a field theory for a structurally disordered magnetic system coupled to a metallic environment near a quantum critical point. We show that close to the magnetic quantum…
Phase diagram of the anisotropic Kondo chain
E. Novais, E. Miranda, A. H. Castro Neto +1
We establish the phase diagram of the one-dimensional anisotropic Kondo lattice model at T=0 using a generalized two-dimensional classical Coulomb gas description. We analyze the p…
Mutagenesis and Metallic DNA
Chun-Min Chang, A. H. Castro Neto, A. R. Bishop
Positions of protons in DNA hydrogen bonds are fundamental for the fidelity of the replication process. Because the hydrogen bond is partially covalent the electronic structure of…
