Resonances for Perturbed Periodic Schrödinger Operator
In the semiclassical regime, we obtain a lower bound for the counting function of resonances corresponding to the perturbed periodic Schrödinger operator 𝑃(ℎ)=−Δ+𝑉(𝑥)+𝑊(ℎ𝑥). Here 𝑉 is a periodic potential, 𝑊 a decreasing perturbation and ℎ a small positive constant.
