Bianchi type IX world with torsion and shear
L. C. Garcia de Andrade, G. A. Monerat
Oscillating phases in Bianchi type IX anisotropic universes are obtained as linearized solutions of Einstein-Cartan theory of gravity.Instead of making use of Weyssenhoff spinning…
Attractive forces between circular polyions of the same charge
Silvia Martins, Jurgen Stilck
We study two models of ringlike polyions which are two-dimensional versions of simple models for colloidal particles (model A) and for rodlike segments of DNA (model B), both in so…
Static phase and dynamic scaling in a deposition model with an inactive species
S. S. Botelho, F. D. A. Aarao Reis
We extend a previously proposed deposition model with two kinds of particles, considering the restricted solid-on-solid condition. The probability of incidence of particle C (A) is…
Physics of Psychophysics: Stevens and Weber-Fechner laws are transfer functions of excitable media
Mauro Copelli, Antonio C. Roque, Rodrigo F. Oliveira +1
Sensory arrays made of coupled excitable elements can improve both their input sensitivity and dynamic range due to collective non-linear wave properties. This mechanism is studied…
Coulomb and quantum oscillator problems in conical spaces with arbitrary dimensions
J. L. A. Coelho, R. L. P. G. Amaral
The Schrödinger equations for the Coulomb and the Harmonic oscillator potentials are solved in the cosmic-string conical space-time. The spherical harmonics with angular deficit ar…
Deuteron Compton Scattering in Chiral Perturbation Theory
M. Malheiro, S. R. Beane, D. R. Phillips +1
Compton scattering on the deuteron is studied in the framework of baryon chiral perturbation theory to third order in small momenta, for photon energies of order the pion mass. The…
