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…
Anomaly-induced vanishing of brane partition functions
Felix B. Christensen, Iñaki García Etxebarria, Enoch Leung
In the presence of 't Hooft anomalies, backgrounds for the symmetries of a quantum field theory can lead to non-conservation of Noether currents, or more generally, to the presence…
Non-Abelian Symmetry Operators from Hanging Branes in
Ibrahima Bah, Federico Bonetti, Mufaro Chitoto +1
We investigate the holographic realization of topological operators for continuous non-Abelian symmetries in quantum field theories. As a concrete case study, we focus on Type IIB…
On the Physics of Higher Condensation Defects
Ibrahima Bah, Enoch Leung, Thomas Waddleton
We study the structure of topological defects for finite Abelian symmetries in quantum field theories, and argue on physical grounds that they satisfy the definition of a higher fu…
Magnification Bias of Distant Galaxies in the Hubble Frontier Fields: Testing Wave vs. Particle Dark Matter Predictions
Enoch Leung, Tom Broadhurst, Jeremy Lim +4
Acting as powerful gravitational lenses, the strong lensing galaxy clusters of the deep Hubble Frontier Fields (HFF) program permit access to lower-luminosity galaxies lying at hig…
