Source and Response Soft Charges for Maxwell Theory on AdS_d
PARTICLES AND ACCELERATORS
Abstract: In this talk, first we argue shortly how some gauge transformations in gauge theories are physical and not redundancy.
We call the generators of those gauge transformations as "soft charges".
Then, we apply the formalism to the case of Maxwell theory on AdS background in dimension greater than 3 and find those degrees of freedom.
This is obtained by constructing a conserved symplectic structure for the bulk and a theory on the boundary, which we specify. We show that the boundary phase space is described by two scalars and two sets of source and response boundary gauge transformations. The bulk dynamics is inv ...
