We will prove its weak convergence to a deterministic probability measure characterized by an equation satisfied by its Stieltjes transform, following Pastur; fluctuations will then be discussed, following a recent preprint of Ji and Lee.

We study the operator norm of this matrix and show that its distribution is comparable to that of the maximum Euclidean norm of the rows of the matrix, settling a conjecture of Latala. The expectation of the norm has an explicit formula in terms of the variance pattern and our result extends to more general Schatten norms. This is a joint work with Rafal Latala and Ramon Van Handel.
