Event Series Quantum Matter in Mathematics and Physics Seminar

Quantum Circuits to local Hamiltonian: role in quantum complexity and new constructions 

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Quantum Matter in Mathematics and Physics Seminar Speaker: Anurag Anshu (Harvard) Title: Quantum Circuits to local Hamiltonian: role in quantum complexity and new constructions Abstract: At the heart of the theory of NP completeness lies a mapping from classical circuits to constraint satisfaction problems (classical local Hamiltonians). The quantum analogue of this is the remarkable history […]

On complete Calabi-Yau metrics and Monge-Ampere equations

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

CMSA Member Seminar Speaker: Freid Tong (Harvard CMSA) Title: On complete Calabi-Yau metrics and Monge-Ampere equations Abstract: Calabi-Yau metrics are central objects in K\"ahler geometry and also string theory. The existence of Calabi-Yau metrics on compact manifolds was answered by Yau in his solution of the Calabi conjecture, but the situation in the non-compact setting is much more delicate, and many questions related to the existence […]

AQFT Lecture Series | Minhyong Kim

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Arithmetic Quantum Field Theory Program Lecture Series Speaker: Minhyong Kim, University of Edinburgh Topic: Arithmetic topology and field theory Abstract: The setup of arithmetic topology as a bridge between the background of QFT to that of arithmetic (both “global” and “local”), including the “middle realm” of positive characteristic function fields. Slides (pdf)

AQFT Lecture Series | Brian Williams

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Arithmetic Quantum Field Theory Program Lecture Series Speaker: Brian Williams, Boston University Topic: Algebraic quantum field theory Abstract: Questions and structures in arithmetic that have been / might be amenable to inspiration from QFT, in particular the theory of L-functions and the Langlands program.

AQFT Lecture Series | David Ben-Zvi

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Arithmetic Quantum Field Theory Program Lecture Series Speaker: David Ben-Zvi Topic: The Langlands program via arithmetic QFT Abstract: Structures in QFT (like factorization for observables and functorial QFT for states and their relation to geometric / deformation quantization) that are sufficiently algebraic and formal to allow for arithmetic analogs.

Noncompact n-dimensional Einstein spaces as attractors for the Einstein flow

Virtual

General Relativity Seminar Speaker: Jinhua Wang, Xiamen University Title: Noncompact n-dimensional Einstein spaces as attractors for the Einstein flow Abstract: We prove that along with the Einstein flow, any small perturbations of an $n$($n\geq4$)-dimensional, non-compact negative Einstein space with some "non-positive Weyl tensor" lead to a unique and global solution, and the solution will be attracted to […]

Flavor hierarchy from smooth confinement & Towards a complete classification of 6d supergravities

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Quantum Matter in Mathematics and Physics Seminar Speaker: Yuta Hamada (KEK, Tsukuba) Title: Flavor hierarchy from smooth confinement & Towards a complete classification of 6d supergravities Abstract: The talk consists of two independent parts. In the first part, I will talk about a new model to explain the Standard Model flavor hierarchy. Our model is […]

Large language models, mathematical discovery, and search in the space of strategies: an anecdote

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

https://youtu.be/SPfLEZ-Ghio New Technologies in Mathematics Seminar Speaker: Jordan Ellenberg (UW Madison) Title: Large language models, mathematical discovery, and search in the space of strategies: an anecdote Abstract: I spent a portion of 2023 working with a team at DeepMind on the “cap set problem” – how large can a subset of (Z/3Z)^n be which contains no […]
