Construction and spectrum of the Schrodinger operator with white noise potential (Cyril Labbé, LPSM, Paris Cité)

10.11.2025 16:15 – 18:00

This talk will focus on the random Schrodinger operator obtained by perturbing the Laplacian on R^2 and R^3 by a white noise. This is a singular operator and one needs to renormalize it using recent tools from stochastic PDEs. I will give a brief review of the literature on this operator, and I will present a result on the identification of its almost sure spectrum. Based on a joint work with Yueh-Sheng Hsu (TU Wien).
