Envelope and waveguide methods : a comparative study of PbF2 and CeO2 birefringent films
(1994) [Journal article]We have characterized low-birefringence, PbF2 coatings to permit, first, agreement between envelope and prism-coupler waveguide methods under the standard isotropic assumption. In essentially the same measurement conditions, ... -
Phase diagram for the Anderson lattice model
(2000) [Journal article]We study the competition between the Kondo effect and the Ruderman-Kittel-Kasuya-Yosida interaction in the framework of the Anderson lattice model with an extra intersite exchange term. By using an approximation based on ...
