Random Sequential Adsorption of Mixtures of Dimers and Monomers on a Pre-Treated Bethe Lattice
Antonio M. R. Cadilhe, Vladimir Privman
We report studies of random sequential adsorption on the pre-patterned Bethe lattice. We consider a partially covered Bethe lattice, on which monomers and dimers deposit competitiv…
Spinflop transition in dopped antiferromagnets
N. M. R. Peres
In this paper we compute the mean field phase diagram of a doped antiferromagnet, in a magnetic field and with anisotropic exchange. We show that at zero temperature there is a met…
Magnetic and superconducting instabilities in the periodic Anderson model: an RPA stud
N. M. R. Peres, M. A. N. Araujo
We study the magnetic and superconducting instabilities of the periodic Anderson model with infinite Coulomb repulsion U in the random phase approximation. The Neel temperature and…
Scaling Study of the Metal-Insulator Transition in one-Dimensional Fermion Systems
Shi-Jian Gu, Vitor M. Pereira, N. M. R. Peres
We consider the Ising phase of the antiferromagnetic XXZ Heisenberg chain on a finite-size lattice with N sites.We compute the large behavior of the spin stiffness, obtaining t…
Spin waves in La_2CuO_4: band structure and correlation effects
N. M. R. Peres, M. A. N. Araujo
We calculate the antiferromagnetic spin wave dispersion in the half-filled (electronic density n=1) Hubbard model for a two-dimensional square lattice, using the random phase appro…
