abstract
For general non-Hermitian random matrices $X$ and deterministic deformation matrices $A$, we prove that the local eigenvalue statistics of $A+X$ close to the typical edge points of its spectrum are universal. Furthermore, we show that under natural assumptions on $A$ the spectrum of $A+X$ does not have outliers at a distance larger than the natural fluctuation scale of the eigenvalues. As a consequence, the number of eigenvalues in each component of $\mathrm{Spec}(A+X)$ is deterministic.

The Zigzag Strategy for Random Band Matrices
For random band matrices with width W >> sqrt(N), the paper proves complete delocalization, Wigner-Dyson statistics, and quantum unique ergodicity for general distributions and variance profiles.

Spectral radius concentration for inhomogeneous random matrices with independent entries
For inhomogeneous random matrices, the spectral radius is bounded by the variance row/column sums up to the optimal sparsity (log n)^{-1/2}.
