Nonmonotonic Evolution of the Blocking Temperature in Dispersions of Superparamagnetic Nanoparticles
D. Serantes, D. Baldomir, M. Pereiro +3
We use a Monte Carlo approach to simulate the influence of the dipolar interaction on assemblies of monodisperse superparamagnetic nanoparticles. We have identified…
SrCo0{}: non-one-dimensional behavior of a charge ordered structurally quasi-one-dimensional oxide
A. S. Botana, P. M. Botta, C. de la Calle +4
We have synthesized SrCoO, a quasi-one-dimensional oxide, measured its magnetic properties and calculated its electronic structure by ab initio techniques. We have f…
Theory and computation of directional nematic phase ordering
Ezequiel R. Soulé, Nasser Mohieddin Abukhdeir. Alejandro D. Rey
A computational study of morphological instabilities of a two-dimensional nematic front under directional growth was performed using a Landau-de Gennes type quadrupolar tensor orde…
Non-Isothermal Model for Nematic Spherulite Growth
Nasser Mohieddin Abukhdeir, Ezequiel R. Soule, Alejandro D. Rey
A computational study of the growth of two-dimensional nematic spherulites in an isotropic phase was performed using a Landau-de Gennes type quadrupolar ensor order parameter model…
Stark effect on a geometry defined by a cake' slice
Jorge-Alejandro Reyes-Esqueda, Carlos I. Mendoza, Marcelo del Castillo-Mussot +1
By using a variational calculation, we study the effect of an external applied electric field on the ground state of electrons confined in a quantum box with a geometry defined by…
Cooper Pairing Revisited
V. C. Aguilera-Navarro, M. Fortes, M. de Llano +1
We recall the fundamental fact that Cooper pairs defined without ignoring two- hole pairs along with two-particle ones leads to a purely imaginary pair energy when the problem is b…
