For z away from the real axis the formula coincides with that for the complex Ginibre ensemble we derived earlier in Cipolloni et al. (Prob Math Phys 1:101–146, 2020). On the level of the one-point function of the low lying singular values we thus confirm the transition from real to complex Ginibre ensembles as the shift parameter z becomes genuinely complex; the analogous phenomenon has been well known for eigenvalues. We use the superbosonization formula (Littelmann et al. in Comm Math Phys 283:343–395, 2008) in a regime where the main contribution comes from a three dimensional saddle manifold."}],"intvolume":" 23","month":"11","scopus_import":"1","language":[{"iso":"eng"}],"file":[{"creator":"dernst","date_updated":"2023-01-27T11:06:47Z","file_size":1333638,"date_created":"2023-01-27T11:06:47Z","file_name":"2022_AnnalesHenriP_Cipolloni.pdf","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"12424","checksum":"5582f059feeb2f63e2eb68197a34d7dc","success":1}],"publication_status":"published","publication_identifier":{"eissn":["1424-0661"],"issn":["1424-0637"]},"issue":"11","volume":23,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Cipolloni, Giorgio, et al. “Density of Small Singular Values of the Shifted Real Ginibre Ensemble.” Annales Henri Poincaré, vol. 23, no. 11, Springer Nature, 2022, pp. 3981–4002, doi:10.1007/s00023-022-01188-8.","short":"G.

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.","lang":"eng"}],"intvolume":" 22","month":"12","scopus_import":"1","language":[{"iso":"eng"}],"file":[{"success":1,"file_id":"11365","checksum":"8d6bac0e2b0a28539608b0538a8e3b38","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_name":"2021_AnnHenriPoincare_Erdoes.pdf","date_created":"2022-05-12T12:50:27Z","file_size":1162454,"date_updated":"2022-05-12T12:50:27Z","creator":"dernst"}],"publication_status":"published","publication_identifier":{"eissn":["1424-0661"],"issn":["1424-0637"]},"ec_funded":1,"volume":22,"_id":"9912","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","ddc":["510"],"date_updated":"2023-08-11T10:31:48Z","department":[{"_id":"LaEr"}],"file_date_updated":"2022-05-12T12:50:27Z"},{"oa_version":"Published Version","abstract":[{"lang":"eng","text":"We consider the Nelson model with ultraviolet cutoff, which describes the interaction between non-relativistic particles and a positive or zero mass quantized scalar field.
