Edge modes and surface-preserving symmetries in Einstein-Maxwell theory
Einstein-Maxwell theory is not only covariant under diffeomorphisms but also is under U(1) gauge transformations. We introduce a combined transformation constructed out of diffeomorphism and U(1) gauge transformation. We show that symplectic potential, which is defined in covariant phase space metho...
