Unified Homogenization Theory for Magnetoinductive and Electromagnetic Waves in Split Ring Metamaterials

J. D. Baena, L. Jelinek, R. Marques +1

A unified homogenization procedure for split ring metamaterials taking into account time and spatial dispersion is introduced. The procedure is based on two coupled systems of equa…

Constraints on economical 331 models from mixing of K, Bd and Bs neutral mesons

J. M. Cabarcas, D. Gomez Dumm, R. Martinez

We analyze the effect of flavor changing neutral currents within 331 models. In particular, we concentrate in the so-called "economical" models, which have a minimal scalar sector.…

BCS theory for finite size superconductors

Antonio M. Garcia-Garcia, Juan D. Urbina, Emil A. Yuzbashyan +2

We study finite size effects in superconducting metallic grains and determine the BCS order parameter and the low energy excitation spectrum in terms of size, and shape of the grai…

Thorn independence in the field of real numbers with a small multiplicative group

Alexander Berenstein, Clifton Ealy, Ayhan Günaydin

We characterize thorn-independence in a variety of structures, focusing on the field of real numbers expanded by predicate defining a dense multiplicative subgroup, G, satisfying t…

Electroweak standard model at finite temperature in presence of a bosonic chemical potential

C. Pena, C. Quimbay

We study the electroweak standard model at finite temperature in presence of a bosonic chemical potential associated with the conserved electromagnetic current. To preserve the the…
