Competition and coexistence of superconducting symmetries in -wave magnets
J. E. C. Carmelo, I. R. Pimentel, P. D. Sacramento
We investigate the interplay between unconventional magnetism and superconductivity in a model of a -wave magnet on a square lattice. Using a self-consistent Bogoliubov-de-Genne…
Spin Glass Field Theory with Replica Fourier Transforms
I. R. Pimentel, C. De Dominicis
We develop a field theory for spin glasses using Replica Fourier Transforms (RFT). We present the formalism for the case of replica symmetry and the case of replica symmetry breaki…
Spin Correlations and Magnetic Susceptibilities of Lightly Doped Antiferromagnets
F. Carvalho Dias, I. R. Pimentel
We calculate the spin correlation function and the magnetic longitudinal and transverse susceptibilities of a two-dimensional antiferromagnet doped with a small concentration of ho…
Persistent current and Drude weight in mesoscopic rings
F. Carvalho Dias, I. R. Pimentel, M. Henkel
We study the persistent current and the Drude weight of a system of spinless fermions, with repulsive interactions and a hopping impurity, on a mesoscopic ring pierced by a magneti…
Spin glass transition in a magnetic field: a renormalization group study
I. R. Pimentel, T. Temesvari, C. De Dominicis
We study the transition of short range Ising spin glasses in a magnetic field, within a general replica symmetric field theory, which contains three masses and eight cubic coupling…
Generic replica symmetric field-theory for short range Ising spin glasses
T. Temesvari, C. De Dominicis, I. R. Pimentel
Symmetry considerations and a direct, Hubbard-Stratonovich type, derivation are used to construct a replica field-theory relevant to the study of the spin glass transition of short…
