Accuracy of the coherent potential approximation for a one-dimensional array with a Gaussian distribution of fluctuations in the on-site potential
I. Avgin, D. L. Huber
We investigate the accuracy of the coherent potential approximation (CPA) for a one-dimensional array with nearest-neighbor interactions and a Gaussian distribution of fluctuations…

Classical generalized constant coupling model for geometrically frustrated antiferromagnets
A. J. Garcia-Adeva, D. L. Huber
A generalized constant coupling approximation for classical geometrically frustrated antiferromagnets is presented. Starting from a frustrated unit we introduce the interactions wi…
