The random operator can be considered as a perturbation of a periodic one. As soon as the disorder is switched on via a global coupling constant, the spectrum expands. We estimate how much the spectrum expands at its bottom for operators on ℓ²(ℤᵈ).en0022-1236Journal of functional analysis2016516841718Almost sure spectrumExpansion of the spectrumWeak disorderMathematical PhysicsMathematical PhysicsMathematics - Mathematical PhysicsExpansion of the almost sure spectrum in the weak disorder regimeJournal Article10.1016/j.jfa.2015.12.0181408.2113v2Other
