Non-dispersive one-way signal amplification in sonic metamaterials
Jefferson 256 17 Oxford Street, Cambridge, MA, United StatesActive Matter Seminar Speaker: Jayson Paulose, University of Oregon Title: Control of parametric amplification in space-time modulated mechanical metamaterials Abstract: Active mechanical metamaterials harbor acoustic signal processing functionalities that are impossible to achieve in passive structures. Amplifying an elastic wave as it passes through the material is a prominent example, with potential applications in acoustic signal […]
Symmetry Colloquia – Global Categorical Symmetries
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesSymmetry Colloquia - Global Categorical Symmetries May 2, 2024 Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Speaker: Clay Còrdova, University of Chicago Title: Particle-Soliton Degeneracies from Spontaneously Broken Non-Invertible Symmetry Abstract: We study non-invertible topological symmetry operators in massive quantum field theories in (1+1) dimensions. In phases where this symmetry is spontaneously broken […]

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesSymmetry Colloquia - Global Categorical Symmetries May 2, 2024 Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Speaker: Theo Johnson-Freyd, Dalhousie University and Perimeter Institute Title: The Universal Target Category Abstract: Hilbert's Nullstellensatz says that the complex numbers C satisfy a universal property among all R-algebras: every not-too-large nonzero commutative R-algebra maps to C. Deligne proved a similar statement […]
