Abstract: The overall goal of this series of talks is to introduce a categorical framework where fusion 2-categories can be used to understand topological theories in 3+1d. in this first talk I will give an introduction to fusion 2-categories in the...

Abstract: Recent advancements in generalized symmetries have drawn significant attention to gapped phases of matter exhibiting novel symmetries, such as noninvertible symmetries. By leveraging the duality transformations, the classification and...

Abstract: The Navier–Stokes (NS) equations describe fluid dynamics through a high-dimensional, nonlinear partial differential equations (PDEs) system. Despite their fundamental importance, their behavior in turbulent regimes remains incompletely...

Abstract: The detection of gravitational waves from inspiraling binary black holes by the LIGO/Virgo/KAGRA experiment has brought about the era of precision strong-gravity science. In this talk, I will discuss recent progress in uncovering the...

Abstract: Theories comprehensively addressing the origin and robustness of the observed hierarchical structure of particle physics face significant challenges from the non-appearance of new particles, explicitly in LHC searches or virtually within...

Abstract: We develop a non-perturbative definition of RMT2: a generalization of random matrix theory that is compatible with the symmetries of two-dimensional conformal field theory. Given any random matrix ensemble, its n-point spectral...

Abstract: A recursive extension of $\phi^3$ amplitudes was discovered in 2019 by CEGM.  The first layer is a familiar integral over the positive moduli space $M^+_{0,n}$; the second layer is an integral over the moduli space of polygons in the...

Abstract: We begin with understanding scalar color-ordered amplitudes via the kinematic mesh and the ABHY associahedron. There are three important aspects of this construction: its zeros, large deformations and splitting. The zeros will imply the...

Abstract: Quantum condensed matter has traditionally focused on ground states and equilibrium properties of spatially extended systems, such as electrons in crystalline materials. However, the advent of noisy-intermediate-scale-quantum (NISQ)...

Abstract: Informally, a quantum cellular automaton (QCA) describes some discrete-time local dynamics of a quantum system.  Formally, a QCA is a *-automoprhism of the algebra of local operators.  Local quantum circuits provide one example of QCA, but...
