Boundary Actions and Loop Groups: A Geometric Picture of Gauge Symmetries at Null Infinity
Silvia Nagy, Javier Peraza, Giorgio Pizzolo
In previous work arXiv:2407.13556, we proposed an extended phase space structure at null infinity accommodating large gauge symmetries for sub-leading soft theorems in Yang-Mil…

Periodic Kerr solution as an infinite soliton chain
Dmitry Korotkin, Javier Peraza
We combine numerical analysis with the inverse scattering method to study the periodic analog of Kerr solution. The periodic analog of the Schwarzschild solution is known to be reg…
