1311.6915 | in this study , we present non - linear spin wave analysis of a quasi 2d spin-@xmath0 @xmath1 antiferromagnet at the parameter regime relevant for the recently studied compound @xmath2 . we obtain the temperature dependence of the spin wave energy , susceptibility and magnetization using green s function technique and ... | 154 |
astro-ph9705134 | density inhomogeneities along the line - of - sight distort fluctuations in the cosmic microwave background . usually , this effect is thought of as a small second - order effect that mildly alters the statistics of the microwave background fluctuations . we show that there is a first - order effect that is potentially... | 175 |
