Abstract (EN)

We consider the continuous Anderson Hamiltonian with white noise potential on (−L/2,L/2)d in dimension d≤3, and derive the asymptotic of the smallest eigenvalues when L goes to infinity. We show that these eigenvalues go to −∞ at speed (logL)1/(2−d/2) and identify the prefactor in terms of the optimal constant of the Gagliardo-Nirenberg inequality. This result was already known in dimensions 1 and 2, but appears to be new in dimension 3. We present some conjectures on the fluctuations of the eigenvalues and on the asymptotic shape of the corresponding eigenfunctions near their localisation centers.
