The top eigenvalues of H^{(N)} and those of its immediate minor H^{(N-1)} are very strongly correlated, but this correlation becomes weaker for smaller minors H^{(N-k)} as k increases. For the GUE minor process the critical transition regime around k\\sim N^{2/3} was analyzed by Forrester and Nagao (J. Stat. Mech.: Theory and Experiment, 2011) providing an explicit formula for the nontrivial joint correlation function. We prove that this formula is universal, i.e. it holds for the Wigner minor process. Moreover, we give a complete analysis of the sub- and supercritical regimes both for eigenvalues and for the corresponding eigenvector overlaps, thus we prove the decorrelation transition in full generality.","lang":"eng"}],"department":[{"_id":"LaEr"}],"month":"09","scopus_import":"1","OA_place":"publisher","publication":"Probability Theory and Related Fields","quality_controlled":"1","date_published":"2025-09-20T00:00:00Z","ec_funded":1,"PlanS_conform":"1","type":"journal_article","year":"2025","doi":"10.1007/s00440-025-01422-4","author":[{"last_name":"Bao","first_name":"Zhigang","full_name":"Bao, Zhigang","id":"442E6A6C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3036-1475"},{"last_name":"Cipolloni","full_name":"Cipolloni, Giorgio","first_name":"Giorgio","orcid":"0000-0002-4901-7992","id":"42198EFA-F248-11E8-B48F-1D18A9856A87"},{"id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5366-9603","first_name":"László","full_name":"Erdös, László","last_name":"Erdös"},{"first_name":"Sven Joscha","full_name":"Henheik, Sven Joscha","id":"31d731d7-d235-11ea-ad11-b50331c8d7fb","orcid":"0000-0003-1106-327X","last_name":"Henheik"},{"full_name":"Kolupaiev, Oleksii","first_name":"Oleksii","orcid":"0000-0003-1491-4623","id":"149b70d4-896a-11ed-bdf8-8c63fd44ca61","last_name":"Kolupaiev"}],"acknowledgement":"Open access funding provided by Institute of Science and Technology (IST Austria).
