We revisit this problem in the large N regime allowing for (i) arbitrary ratio 𝜙:=𝑁/𝑀≤1; and (ii) general distributions for the matrix elements of the Hamiltonian of the quantum dot. In the limit 𝜙→0, we recover the formula for the density 𝜌 that Beenakker (Rev Mod Phys 69:731–808, 1997) has derived for a special matrix ensemble. We also prove that the inverse square root singularity of the density at zero and full transmission in Beenakker’s formula persists for any 𝜙<1 but in the borderline case 𝜙=1 an anomalous 𝜆−2/3 singularity arises at zero. To access this level of generality, we develop the theory of global and local laws on the spectral density of a large class of noncommutative rational expressions in large random matrices with i.i.d. entries."}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"        22","has_accepted_license":"1","date_created":"2021-08-15T22:01:29Z","article_type":"original","volume":22,"oa_version":"Published Version","title":"Scattering in quantum dots via noncommutative rational functions","scopus_import":"1","day":"01","author":[{"last_name":"Erdös","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","full_name":"Erdös, László","orcid":"0000-0001-5366-9603","first_name":"László"},{"last_name":"Krüger","id":"3020C786-F248-11E8-B48F-1D18A9856A87","full_name":"Krüger, Torben H","first_name":"Torben H","orcid":"0000-0002-4821-3297"},{"last_name":"Nemish","id":"4D902E6A-F248-11E8-B48F-1D18A9856A87","full_name":"Nemish, Yuriy","first_name":"Yuriy","orcid":"0000-0002-7327-856X"}],"date_published":"2021-12-01T00:00:00Z","acknowledgement":"The authors are very grateful to Yan Fyodorov for discussions on the physical background and for providing references, and to the anonymous referee for numerous valuable remarks.","ec_funded":1,"status":"public","publication":"Annales Henri Poincaré ","project":[{"grant_number":"338804","name":"Random matrices, universality and disordered quantum systems","call_identifier":"FP7","_id":"258DCDE6-B435-11E9-9278-68D0E5697425"}],"external_id":{"arxiv":["1911.05112"],"isi":["000681531500001"]},"isi":1,"year":"2021","quality_controlled":"1","ddc":["510"],"page":"4205–4269","type":"journal_article","_id":"9912","date_updated":"2023-08-11T10:31:48Z","publisher":"Springer Nature","article_processing_charge":"Yes (in subscription journal)","doi":"10.1007/s00023-021-01085-6"},{"main_file_link":[{"url":"https://arxiv.org/abs/1804.11340","open_access":"1"}],"quality_controlled":"1","doi":"10.1016/j.jfa.2020.108507","article_processing_charge":"No","publisher":"Elsevier","date_updated":"2023-08-18T06:36:10Z","_id":"7512","type":"journal_article","project":[{"grant_number":"338804","name":"Random matrices, universality and disordered quantum systems","call_identifier":"FP7","_id":"258DCDE6-B435-11E9-9278-68D0E5697425"}],"publication":"Journal of Functional Analysis","status":"public","ec_funded":1,"acknowledgement":"The authors are grateful to Oskari Ajanki for his invaluable help at the initial stage of this project, to Serban Belinschi for useful discussions, to Alexander Tikhomirov for calling our attention to the model example in Section 6.2 and to the anonymous referee for suggesting to simplify certain proofs.
