Effects of quantum zero-point spin fluctuations on the ground state of plutonium
arXiv:1310.7184
Abstract
The magnetic stability of δ-plutonium is analyzed taking into account zero-point spin fluctuations. Within the generalized theory of spin fluctuations described within a simple phenomenological model neglecting its spatial dispersion we show that zero-point local magnetic moments are giant (at.Pu) and suppress the magnetic order predicted by ab initio calculations resulting in the observed paramagnetic state of δ-plutonium.
