Autor: de Andrade, M. C., Chau, R., Dickey, R. P., Dilley, N. R., Freeman, E. J., Gajewski, D. A., Maple, M. B., Movshovich, R., Neto, A. H. Castro, Castilla, G. E., Jones, B. A.

The non-Fermi-liquid (NFL) behavior observed in the low temperature specific heat $C(T)$ and magnetic susceptibility $\chi(T)$ of f-electron systems is analyzed within the context of a recently developed theory based on Griffiths singularities. Measu

Nonlinear $\sigma$-model is an ubiquitous model. In this paper, the $O(N)$ model where the $N$-component spin is a unit vector, ${\bf S}^2=1$,is considered. The stability of this model with respect to gradient operators $(\partial_{\mu}{\bf S}\cdot \
