Continuous symmetries and charge measurement of boundary operators in holography
Ibrahima Bah, Federico Bonetti, Mufaro Chitoto +1
We study holographic charge measurement for continuous internal symmetries. Charged boundary operators are characterized by Wilson lines of bulk gauge fields ending on the boundary…
