Strong-disorder localisation under absence of supported formal solutions
Strong-disorder localisation under absence of supported formal solutions
Let be a -trimmed random Schrödinger operator on satisfying the Assumptions. Suppose that the complement of is a union of finite connected components, and let be such that the eigenvalue equation
has no non-trivial formal solution supported on . Strong-disorder localisation conjecture. Then the fractional-moment bound holds for sufficiently large .
This would generalise the two preceding localisation theorems: localisation away from the spectrum of the trimmed operator, and localisation under the double-insulation condition. The conjecture concerns Anderson localisation at energies where no formal solution supported on the untrimmed components obstructs the fractional-moment method.
