The Skyrmion Model and the Dynamical Breakdown of Chiral Symmetry

Autor: Braghin, F. L., Cavalcante, I. P.

Publikováno v: Phys.Rev. C67 (2003) 065207

A scalar field, $\eta({\bf r})$, is coupled to the skyrmion. Its classical value in the vacuum ("condensate") reduces to the pion decay constant, $f_{\pi}$, being thus proportional to the chiral condensate $<\bar{q} q>$. A quadratic coupling of the s

On the Fly' Characterization of YbIII:ErIII Co-Doped Upconversion Nanoparticle Nonlinear Optical Response from Single-Particle Trajectories

Autor: Cavalcante I, Barja Bc, Marchi Mc, Rene A. Nome, de Sousa Filho Pc, Sigoli F

Spectroscopic characterization of individual nanoparticles is essential for understanding their structure-property relationship and for applications. Upconversion nanoparticles (UCNPs) in condensed phases can undergo both nonlinear optical and stocha
