Abstract

The Anderson Hamiltonian H0=Δ+V(x,ω)H_0=-\Delta+V(x,\omega) is considered, where VV is a random potential of Bernoulli type. The operator H0H_0 is perturbed by a non-random, continuous potential v(x)0-v(x) \leq 0, decaying at infinity. It will be shown that the borderline between finitely, and infinitely many negative eigenvalues of the perturbed operator, is achieved with a decay of the potential v(x)-v(x) as O(ln2/dx)O(\ln^{-2/d} |x|).
