Emergence of graviton-like excitations from a lattice model
Speaker: Xiao-Gang Wen (MIT) Title: Emergence of graviton-like excitations from a lattice model Abstract: I will review some construction of lattice rotor model which give rise to emergent photons and graviton-like excitations. The appearance of vector-like charge and symmetric tensor field may be related to gapless fracton phases.

Data-intensive Innovation and the State: Evidence from AI Firms in China
Speaker: David Yang (Harvard) Title: Data-intensive Innovation and the State: Evidence from AI Firms in China Abstract: Data-intensive technologies such as AI may reshape the modern world. We propose that two features of data interact to shape innovation in data-intensive economies: first, states are key collectors and repositories of data; second, data is a non-rival input in innovation. We document the importance of state-collected data for innovation using comprehensive data on Chinese facial recognition AI firms and government contracts. […]
