[{"type":"journal_article","issue":"4","abstract":[{"text":"Consider the random matrix model A1/2UBU∗A1/2, where A and B are two N × N deterministic matrices and U is either an N × N Haar unitary or orthogonal random matrix. It is well known that on the macroscopic scale (Invent. Math. 104 (1991) 201–220), the limiting empirical spectral distribution (ESD) of the above model is given by the free multiplicative convolution\r\nof the limiting ESDs of A and B, denoted as μα \u0002 μβ, where μα and μβ are the limiting ESDs of A and B, respectively. In this paper, we study the asymptotic microscopic behavior of the edge eigenvalues and eigenvectors statistics. We prove that both the density of μA \u0002μB, where μA and μB are the ESDs of A and B, respectively and the associated subordination functions\r\nhave a regular behavior near the edges. Moreover, we establish the local laws near the edges on the optimal scale. In particular, we prove that the entries of the resolvent are close to some functionals depending only on the eigenvalues of A, B and the subordination functions with optimal convergence rates. Our proofs and calculations are based on the techniques developed for the additive model A+UBU∗ in (J. Funct. Anal. 271 (2016) 672–719; Comm. Math.\r\nPhys. 349 (2017) 947–990; Adv.

We focus on estimators based on approximate message passing (AMP), a family of iterative algorithms with many appealing features: the performance of AMP in the high-dimensional limit can be succinctly characterized under suitable model assumptions; AMP can also be tailored to the empirical distribution of the signal entries, and for a wide class of estimation problems, AMP is conjectured to be optimal among all polynomial-time algorithms. However, a major issue of AMP is that in many models (such as phase retrieval), it requires an initialization correlated with the ground-truth signal and independent from the measurement matrix. Assuming that such an initialization is available is typically not realistic. In this paper, we solve this problem by proposing an AMP algorithm initialized with a spectral estimator. With such an initialization, the standard AMP analysis fails since the spectral estimator depends in a complicated way on the design matrix. Our main contribution is a rigorous characterization of the performance of AMP with spectral initialization in the high-dimensional limit. The key technical idea is to define and analyze a two-phase artificial AMP algorithm that first produces the spectral estimator, and then closely approximates the iterates of the true AMP. We also provide numerical results that demonstrate the validity of the proposed approach."}],"citation":{"ama":"Mondelli M, Venkataramanan R.

In this manuscript we develop an alternative analytical and numerical framework for many-body quantum spin ground states, based on the disentanglement formalism. In this approach, observables are exactly expressed as Gaussian-weighted functional integrals over scalar fields. We identify the leading contribution to these integrals, given by the saddle point of a suitable effective action. Analytically, we develop a field-theoretical expansion of the functional integrals, performed by means of appropriate Feynman rules. The expansion can be truncated to a desired order to obtain analytical approximations to observables. Numerically, we show that the disentanglement approach can be used to compute ground state expectation values from classical stochastic processes. While the associated fluctuations grow exponentially with imaginary time and the system size, this growth can be mitigated by means of an importance sampling scheme based on knowledge of the saddle point configuration. We illustrate the advantages and limitations of our methods by considering the quantum Ising model in 1, 2 and 3 spatial dimensions. Our analytical and numerical approaches are applicable to a broad class of systems, bridging concepts from quantum lattice models, continuum field theory, and classical stochastic processes.","lang":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"9158","intvolume":" 2021","status":"public","ddc":["530"],"title":"Disentanglement approach to quantum spin ground states: Field theory and stochastic simulation","oa_version":"Published Version","file":[{"file_size":1693609,"content_type":"application/pdf","creator":"dernst","file_name":"2021_JourStatMech_deNicola.pdf","access_level":"open_access","date_updated":"2021-02-19T14:04:40Z","date_created":"2021-02-19T14:04:40Z","checksum":"64e2aae4837790db26e1dd1986c69c07","success":1,"relation":"main_file","file_id":"9172"}]},{"keyword":["Statistics","Probability and Uncertainty","Statistics and Probability"],"day":"01","article_processing_charge":"No","article_type":"original","page":"315-380","publication":"Annals of Mathematics","citation":{"ista":"Kaloshin V, Sorrentino A. 2018.

In this article we prove a complete local version of this conjecture: a small integrable perturbation of an ellipse must be an ellipse. This extends and completes the result in Avila-De Simoi-Kaloshin, where nearly circular domains were considered. One of the crucial ideas in the proof is to extend action-angle coordinates for elliptic billiards into complex domains (with respect to the angle), and to thoroughly analyze the nature of their complex singularities. As an application, we are able to prove some spectral rigidity results for elliptic domains."}],"issue":"1","title":"On the local Birkhoff conjecture for convex billiards","status":"public","intvolume":" 188","_id":"8421","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Preprint","month":"07","publication_identifier":{"issn":["0003-486X"]},"quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1612.09194"}],"oa":1,"external_id":{"arxiv":["1612.09194"]},"language":[{"iso":"eng"}],"doi":"10.4007/annals.2018.188.1.6","extern":"1","publication_status":"published","publisher":"Annals of Mathematics, Princeton U","year":"2018","date_updated":"2021-01-12T08:19:10Z","date_created":"2020-09-17T10:42:22Z","volume":188,"author":[{"full_name":"Kaloshin, Vadim","orcid":"0000-0002-6051-2628","id":"FE553552-CDE8-11E9-B324-C0EBE5697425","last_name":"Kaloshin","first_name":"Vadim"},{"full_name":"Sorrentino, Alfonso","last_name":"Sorrentino","first_name":"Alfonso"}]},{"keyword":["Statistics","Probability and Uncertainty","Statistics and Probability"],"day":"01","month":"09","publication_identifier":{"issn":["0003-486X"]},"article_processing_charge":"No","article_type":"original","quality_controlled":"1","page":"729-741","publication":"The Annals of Mathematics","citation":{"ama":"Kaloshin V.
