A ribbon ZX calculus for gauge theory
Gabriel Wong, Razin A. Shaikh, William Donnelly
ZX calculus provides a graphical formalism for reasoning about quantum processes, built from two interacting Frobenius algebras associated with the Z and X bases of a qubit. While…
Matrix Quantization of Gravitational Edge Modes
William Donnelly, Laurent Freidel, Seyed Faroogh Moosavian +1
Gravitational subsystems with boundaries carry the action of an infinite-dimensional symmetry algebra, with potentially profound implications for the quantum theory of gravity. We…
Gravitational Edge Modes, Coadjoint Orbits, and Hydrodynamics
William Donnelly, Laurent Freidel, Seyed Faroogh Moosavian +1
The phase space of general relativity in a finite subregion is characterized by edge modes localized at the codimension-2 boundary, transforming under an infinite-dimensional group…
Entanglement entropy and edge modes in topological string theory: I
William Donnelly, Yikun Jiang, Manki Kim +1
Progress in identifying the bulk microstate interpretation of the Ryu-Takayanagi formula requires understanding how to define entanglement entropy in the bulk closed string theory.…
Entanglement entropy and the large expansion of two-dimensional Yang-Mills theory
William Donnelly, Sydney Timmerman, Nicolás Valdés-Meller
Two-dimensional Yang-Mills theory is a useful model of an exactly solvable gauge theory with a string theory dual at large . We calculate entanglement entropy in the expan…
Cosmic footballs from superrotations
Eugene Adjei, William Donnelly, Victor Py +1
Superrotations arise from singular vector fields on the celestial sphere in asymptotically flat space, and their finite integrated versions have been argued by Strominger and Zhibo…
