abstract
We consider linear spectral statistics of the form $\mathrm{tr} ( \varphi (H))$ for test functions $\varphi$ of low regularity and Wigner matrices $H$ with smooth entry distribution. We show that for functions $\varphi$ in the Sobolev space $H^{1/2+\varepsilon}$ or the space $C^{1/2+\varepsilon}$, that are supported within the spectral bulk of the semicircle distribution, these linear spectral statistics have asymptotic Gaussian fluctuations with the same variance as in the CLT for functions of higher regularity, for any $\varepsilon >0$.

Establishes full LDPs for the largest eigenvalue of sub-Gaussian Wigner matrices via finite-N approximation by restricted annealed free energies, identifying a transition from GOE rate function to non-universal rate at the onset of eigenvector localization.
Mesoscopic CLT for linear eigenvalue statistics of correlated Hermitian matrices, via multivariate cumulant expansion, multi-resolvent local laws, and operator-level variance-kernel analysis.
Variance of mesoscopic linear spectral statistics for random quantum graphs coincides with GOE/GUE.
For smooth Wigner matrices the log-determinant and eigenvalue counting fields converge in law to centered Gaussian, logarithmically correlated random elements in every negative Sobolev space H^{-s}.
