Abstract

We prove that the eigenvalues of a continuum random Schr\"odinger operator Δ+Vω-\Delta+ V_{\omega} of Anderson type, with complex decaying potential, can be bounded (with high probability) in terms of an LqL^q norm of the potential for all qd+1q\leq d+1. This shows that in the random setting, the exponent qq can be essentially doubled compared to the deterministic bounds of Frank (Bull. Lond. Math. Soc., 2011). This improvement is based on ideas of Bourgain (Discrete Contin. Dyn. Syst., 2002) related to almost sure scattering for lattice Schr\"odinger operators.
