Beyond Noether: A Covariant Study of Poisson-Lie Symmetries in Low Dimensional Field Theory
Florian Girelli, Christopher Pollack, Aldo Riello
We explore global Poisson-Lie (PL) symmetries using a Lagrangian, or "covariant phase space" approach, that manifestly preserves spacetime covariance. PL symmetries are the classic…
Edge modes without edge modes
Aldo Riello
We discuss gauge theories of the Yang-Mills kind in finite regions with boundaries, and in particular the definition of the corresponding quasi-local degrees of freedom and their g…
Non-Perturbative 3D Quantum Gravity: Quantum Boundary States and Exact Partition Function
Christophe Goeller, Etera R. Livine, Aldo Riello
We push forward the investigation of holographic dualities in 3D quantum gravity formulated as a topological quantum field theory, studying the correspondence between boundary and…
Notes on a few quasilocal properties of Yang-Mills theory
Henrique Gomes, Aldo Riello
Gauge theories possess non-local features that, in the presence of boundaries, inevitably lead to subtleties. In this article, we continue our study of a unified solution based on…
Soft charges from the geometry of field space
Aldo Riello
Infinite sets of asymptotic soft-charges were recently shown to be related to new symmetries of the -matrix, spurring a large amount of research on this and related questions. N…
Asymptotic Renormalization in Flat Space: Symplectic Potential and Charges of Electromagnetism
Laurent Freidel, Florian Hopfmüller, Aldo Riello
We present a systematic procedure to renormalize the symplectic potential of the electromagnetic field at null infinity in Minkowski space. We work in spacetime dimensions…
