Lifshitz tails for the fractional Anderson model

Martin Gebert, Constanza Rojas-Molina

We consider the $d$ -dimensional fractional Anderson model $(- Δ)^{α} + V_{ω}$ on $ℓ^{2} (Z^{d})$ where $0 < α \leq 1$ . Here $- Δ$ is the negative discrete Laplacian and $V_{ω}$ is the ra…

On pure complex spectrum for truncations of random orthogonal matrices and Kac polynomials

Martin Gebert, Mihail Poplavskyi

Let $O (2 n + ℓ)$ be the group of orthogonal matrices of size $(2 n + ℓ) \times (2 n + ℓ)$ equipped with the probability distribution given by normalized Haar m…
