Analytical self-dual solutions in a nonstandard Yang-Mills-Higgs scenario
R. Casana; M.M. Ferreira Jr.; E. da Hora; C. dos SantosWe have found analytical self-dual solutions within the generalized Yang-Mills-Higgs model introduced in R. Casana et al. (2012) [1]. Such solutions are magnetic monopoles satisfying Bogomol'nyi-Prasad-Sommerfield (BPS) equations and usual finite energy boundary conditions. Moreover, the new solutions are classified in two different types according to their capability of recovering (or not) the usual 't Hooft-P...
Metallochlorophylls of magnesium, copper and zinc: evaluation of the influence ...
Moreira,Leonardo M.; Lima,Adriana; Soares,Rafael R. S.; Batistela,Vagner R.; Gerola,Adriana P.; Hioka,Noboru; Bonacin,Juliano A.; Severino,DivinomarIn this study the role of different metal centers (magnesium, zinc and copper) on the enhancement of the hydrophilic character of metallochlorophylls, was evaluated. The solvatochromism as well as the aggregation process for these compounds in water/ethanol mixtures at different volume ratios were evaluated using Fluorescence, and Resonant Light Scattering (RLS) measurements, aiming to characterize the behavior...
