CMSA Probability Seminar: Geometry of the doubly periodic Aztec dimer model
October 11, 2023 3:30 pmSpeaker: Tomas Berggren
A dimer tiling of Z^d is a collection of edges such that every vertex is covered exactly once. In 2000, Cohn, Kenyon, and Propp showed that 2D dimer tilings satisfy...

Number Theory Seminar: A relative Oda’s criterion
October 11, 2023 3:00 pmSpeaker: Alex Betts
The Neron--Ogg--Shafarevich criterion asserts that an abelian variety over ℚp has good reduction if and only if the Galois action on its ℤℓ-linear Tate module is unramified (for ℓ different...

CMSA New Technologies in Mathematics Seminar: LeanDojo: Theorem Proving with Retrieval-Augmented Language Models
October 11, 2023 2:00 pmSpeaker: Alex Gu
Large language models (LLMs) have shown promise in proving formal theorems using proof assistants such as Lean. However, existing methods are difficult to reproduce or build on, due to private...

CMSA Topological Quantum Matter Seminar: Chern Mosaic and ideal bands in helical trilayer graphene
October 10, 2023 4:00 pmSpeaker: Daniele Guerci
In this talk I will present helical trilayer graphene (hTTG) which is characterized an emergent real-space Chern mosaic pattern resulting from the interface of two incommensurate moiré lattices [1]. This...

Harvard-MIT Algebraic Geometry Seminar: Uniruling projective families over ℂℙ¹ with rational (multi)sections
October 10, 2023 3:00 pmSpeaker: Alex Pieloch
We will discuss a result which states that every projective family over ℂℙ¹ with at most two singular fibres is uniruled by rational (multi)sections. We obtain these rational curves by...

CMSA General Relativity Seminar: Tidal Squeezing of Black Holes
October 10, 2023 11:00 amSpeaker: Maria Rodriguez
Recent developments indicate that Kerr black holes do not deform when perturbed by a static external gravitational field. Relying on hidden symmetries, compelling progress has been achieved to explain that...

CMSA Quantum Matter in Mathematics and Physics: From wave-function collapse and Galois solvability to the realization of non-Abelian topological order on a quantum device
October 6, 2023 10:00 amSpeaker: Nat Tantivasadakarn
I will review our recent set of theoretical works on efficiently preparing long range quantum entanglement with adaptive quantum circuits: the combination of measurements with unitary gates whose choice can...

Open Neighborhood Seminar: Stack-Sorting and Beyond
October 4, 2023 4:30 pmSpeaker: Colin Defant
In 1990, West introduced the stack-sorting map, a combinatorially-defined operator on the set of permutations of size n that serves as a deterministic analogue of Knuth's stack-sorting machine. I will...
