More precisely, we present generalized super-adiabatic theorems for extended but finite and infinite systems, assuming either a uniform gap or a gap in the bulk above the unperturbed ground state. The goal of this Review is to provide an overview of these adiabatic theorems and briefly outline the main ideas and techniques required in their proofs.}, author = {Henheik, Sven Joscha and Wessel, Tom}, issn = {0022-2488}, journal = {Journal of Mathematical Physics}, number = {12}, publisher = {AIP Publishing}, title = {{On adiabatic theory for extended fermionic lattice systems}}, doi = {10.1063/5.0123441}, volume = {63}, year = {2022}, } @article{12214, abstract = {Motivated by Kloeckner’s result on the isometry group of the quadratic Wasserstein space W2(Rn), we describe the isometry group Isom(Wp(E)) for all parameters 0 < p < ∞ and for all separable real Hilbert spaces E. In particular, we show that Wp(X) is isometrically rigid for all Polish space X whenever 0 < p < 1. This is a consequence of our more general result: we prove that W1(X) is isometrically rigid if X is a complete separable metric space that satisfies the strict triangle inequality. Furthermore, we show that this latter rigidity result does not generalise to parameters p > 1, by solving Kloeckner’s problem affirmatively on the existence of mass-splitting isometries. }, author = {Gehér, György Pál and Titkos, Tamás and Virosztek, Daniel}, issn = {1469-7750}, journal = {Journal of the London Mathematical Society}, keywords = {General Mathematics}, number = {4}, pages = {3865--3894}, publisher = {Wiley}, title = {{The isometry group of Wasserstein spaces: The Hilbertian case}}, doi = {10.1112/jlms.12676}, volume = {106}, year = {2022}, } @article{12232, abstract = {We derive a precise asymptotic formula for the density of the small singular values of the real Ginibre matrix ensemble shifted by a complex parameter z as the dimension tends to infinity. 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.}, author = {Cipolloni, Giorgio and Erdös, László and Schröder, Dominik J}, issn = {1424-0661}, journal = {Annales Henri Poincaré}, keywords = {Mathematical Physics, Nuclear and High Energy Physics, Statistical and Nonlinear Physics}, number = {11}, pages = {3981--4002}, publisher = {Springer Nature}, title = {{Density of small singular values of the shifted real Ginibre ensemble}}, doi = {10.1007/s00023-022-01188-8}, volume = {23}, year = {2022}, } @article{12243, abstract = {We consider the eigenvalues of a large dimensional real or complex Ginibre matrix in the region of the complex plane where their real parts reach their maximum value.

In the complex case, these facts have already been established by Bender [Probab. Theory Relat. Fields 147, 241 (2010)] and in the real case by Akemann and Phillips [J. Stat. Phys. 155, 421 (2014)] even for the more general elliptic ensemble with a sophisticated saddle point analysis. The purpose of this article is to give a very short direct proof in the Ginibre case with an effective error term.
