Many-body localization near the critical point

MATHEMATICAL PICTURE LANGUAGE

February 9, 2021      10:00 am
Speaker: John Imbrie - University of Virginia

I will examine the many-body localization (MBL) phase transition in one-dimensional quantum systems with quenched randomness. Having demonstrated the existence of the MBL phase at strong disorder, under a level-statistics...

Some applications of Vojta’s conjecture to arithmetic dynamics

ALGEBRAIC DYNAMICS

February 5, 2021      10:00 am
Speaker: Yohsuke Matsuzawa - Brown University

I will discuss applications of Vojta's conjecture to some problems in arithmetic dynamics, concerning the growth of sizes of coordinates of orbits, greatest common divisors among coordinates, and prime factors of...

Analytic geometry

NUMBER THEORY

February 3, 2021      3:00 pm
Speaker: Peter Scholze - University of Bonn

We will outline a definition of analytic spaces that relates to complex- or rigid-analytic varieties in the same way that schemes relate to algebraic varieties over a field. Joint with...

CMSA Strongly Correlated Quantum Materials and High-Temperature Superconductors Series: Beyond BCS: An Exact Model for Superconductivity and Mottness

CMSA EVENTS

February 3, 2021      10:30 am
Speaker: Philip Phillips - University of Illinois Urbana-Champaign

High-temperature superconductivity in the cuprates remains an unsolved problem because the cuprates start off their lives as Mott insulators in which no organizing principle such a Fermi surface can be invoked to treat ...

CMSA Computer Science for Mathematicians: Counting cliques in real-world graphs

CMSA EVENTS

February 2, 2021      11:30 am
Speaker: Shweta Jain - University of Illinois, Urbana-Champaign

Cliques are important structures in network science that have been used in numerous applications including spam detection, graph analysis, graph modeling, community detection among others. Obtaining the counts of k-cliques in real-world graphs with millions of nodes and edges is a...
