DOI: 10.1103/physrevb.95.104307
Abstract: The Raman spectrum of plutonium dioxide is studied both experimentally and theoretically. Particular attention has been devoted to the identification of high-energy modes at 2110 and $2620\phantom{\rule{0.16em}{0ex}}\mathrm{c}{\mathrm{m}}^{\ensuremath{-}1}$, whose attribution has so far been controversial.

DOI: 10.1109/jlt.2020.3046998
Abstract: Fiber nonlinearities, that lead to nonlinear signal distortion, are normally considered to be the result of an instantaneous material response with respect to the optical field. However, in addition to an instantaneous part, the nonlinear… read more here.
