摘要
Statistical mechanics of 1D multivalent Coulomb gas may be mapped onto non-Hermitian quantum mechanics. We use this example to develop instanton calculus on Riemann surfaces. Borrowing from the formalism developed in the context of Seiberg-Witten duality, we treat momentum and coordinate as complex variables. Constant energy manifolds are given by Riemann surfaces of genus g≥1. The actions along principal cycles on these surfaces obey ODE in the moduli space of the Riemann surface known as Picard-Fuchs equation. We derive and solve Picard-Fuchs equations for Coulomb gases of various charge content. Analysis of monodromies of these solutions around their singular points yields semiclassical spectra as well as instanton effects such as Bloch bandwidth.
演讲者介绍
我的教育始于俄罗斯,在莫斯科物理技术学院学习数学和物理。移居美国后,我于2012年在明尼苏达大学获得博士学位,开始了理论物理学家的研究生涯。起初,我的研究聚焦于超对称规范理论和弦理论的多个方面。然而,自学生时代起,我一直对纯粹抽象数学充满兴趣。约从2017年起,我成为全职数学家。我当前的研究侧重于枚举代数几何、几何表示论与可积系统之间的互动。总的来说,我致力于物理数学的研究,这在当今代表了现代数学的重要组成部分。许多数学家研究的问题来源于弦理论/规范理论。最近,我开始研究数论及其与数学其他分支的联系。如果你是北京地区的博士后或研究生,并有意与我合作,请通过电子邮件联系我。
