Order statistics for edge eigenvectors of Wigner matrices
Zhigang Bao, Teodor Bucht, Kevin Schnelli
In this paper, we establish a general comparison theorem for the order statistics of the edge eigenvectors for generalized Wigner matrices. Consequently, we derive the Gumbel law f…

Eigenvector distribution of random matrices under critical finite-rank deformations
Zhigang Bao, Dong Wang, Yue Zhu
We investigate the eigenvector distribution at the soft edge for Gaussian random matrices with finite-rank deformations, in the critical regime of BBP transition. For finite-rank d…
