Decoding The Origins of Fluidity in Multicellular Systems

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

Active Matter Seminar Speaker: Max Bi (Northeastern University) Title: Decoding The Origins of Fluidity in Multicellular Systems Abstract: Organisms continually adapt to mechanical forces at the cellular and tissue levels, a process crucial for sustaining vital life functions. In pivotal physiological processes, such as cancer progression and embryonic development, tissues are often poised near solid-like […]

Modularity and Fibrations in Mirror Symmetry

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

CMSA Member Seminar Speaker: Chuck Doran (Harvard CMSA) Title: Modularity and Fibrations in Mirror Symmetry Abstract: We will introduce appearances of modularity in the study both of families of Calabi-Yau threefolds and of their enumerative invariants.  An important role is played by the structure of fibrations and the DHT fibration-degeneration mirror correspondence, which clarifies how these notions […]

AQFT Lecture Series

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

AQFT Lecture Series Speaker: Jayce Getz (Duke University) Title: The Poisson summation conjecture and the fiber bundle method Abstract: The Poisson summation conjecture of Braverman-Kazhdan, L. Lafforgue, Ngo, and Sakellaridis predicts that spherical varieties over a global field admit Schwartz spaces, Fourier transforms, and a generalized Poisson summation formula. In this talk I will state a rough form […]

Linearised Second Law for Higher Curvature Gravity and Non-Minimally Coupled Vector Fields

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

General Relativity Seminar Speaker: Zihan Yan, Cambridge University Title: Linearised Second Law for Higher Curvature Gravity and Non-Minimally Coupled Vector Fields Abstract: Expanding the work of arXiv:1504.08040, we show that black holes obey a second law for linear perturbations to bifurcate Killing horizons, in any covariant higher curvature gravity coupled to scalar and vector fields. The vector […]

Event Series Algebraic Geometry in String Theory Seminar

Derived categories of genus one curves and torsors over abelian varieties

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

Algebraic Geometry in String Theory Seminar Speaker: Jonathan Rosenberg, University of Maryland Title: Derived categories of genus one curves and torsors over abelian varieties   Abstract:  Studying orientifold string theories on elliptic curves or abelian varieties motivates studying the derived category of coherent sheaves on a genus one curve or a torsor over an abelian variety over the […]

Shape morphing with swelling hydrogels and expanding foams

Hybrid - G10

Active Matter Seminar Speaker: Abby Plummer, Boston University Title: Shape morphing with swelling hydrogels and expanding foams Abstract: Materials that increase in size offer intriguing possibilities for shape-morphing applications. Here, we explore two such systems—swelling polyacrylamide hydrogels and expanding polyurethane foams. The hydrogels swell by absorbing water into crosslinked polymer networks. They can therefore be […]

Discrete geometry and the modular bootstrap

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

Quantum Matter in Mathematics and Physics Seminar Speaker: Henry Cohn (MIT and Microsoft) Title: Discrete geometry and the modular bootstrap Abstract: In this talk, I'll discuss the remarkable connections between the modular bootstrap and sphere packing or ground state problems discovered by Hartman, Mazáč, and Rastelli in 2019, with a focus on opportunities for further […]

Phase diagram and confining strings in a minimal model of nematopolar matter

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

CMSA Member Seminar Speaker: Farzan Vafa Title: Phase diagram and confining strings in a minimal model of nematopolar matter Abstract: We investigate a minimal model of a nematopolar system. We analytically uncover a phase diagram consisting of a locked phase where the polar order and nematic order are locked, and unlocked phases which could be […]
