Abstract

In this paper, we investigate random operators on Zd\mathbb{Z}^d with H\"older continuously distributed potentials and the long-range hopping. The hopping amplitude decays with the inter-particle distance x\|\bm x\| as elogρ(x+1)e^{-\log^{\rho}(\|\bm x\|+1)} with ρ>1,xZd\rho>1,\bm x\in\Z^d. By employing the multi-scale analysis (MSA) technique, we prove that for large disorder, the random operators have pure point spectrum with localized eigenfunctions whose decay rate is the same as the hopping term. This gives a partial answer to a conjecture of Yeung and Oono [{\it Europhys. Lett.} 4(9), (1987): 1061-1065].
