Comments Welcome", "categories": [ "math.PR", "math-ph", "math.MP" ], "abstract": "We continue investigating spectral properties of a Hermitised random matrix product, which, contrary to previous product ensembles, allows for eigenvalues on the full real line. When a GUE matrix with an external source is involved, we prove that the eigenvalues of the product form a determinantal point process and derive a double integral representation for correlation kernel. As the source changes, we observe a critical value and establish the existence of a phase transition for scaled eigenvalues at the origin. Particularly in the critical case, we obtain a new family of Pearcey-type kernels.", "revisions": [ { "version": "v1", "updated": "2017-06-19T21:51:54.000Z" } ], "analyses": { "subjects": [ "60B20" ], "keywords": [ "product matrix ensembles", "external source", "spectral statistics", "hermite type", "hermitised random matrix product" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
