Resolving BCFT bulk-cone singularities in braneworlds and top-down holography
Dongming He, Christoph F. Uhlemann
Two-point functions in BCFTs exhibit characteristic singularities compared to standard CFTs due to reflected light cones. In holographic BCFTs, further singularities, which need no…
One-point functions for doubly-holographic BCFTs and backreacting defects
Dongming He, Christoph F. Uhlemann
We derive one-point functions in 4d SYM with -BPS boundaries, defects and interfaces which host large numbers of defect degrees of freedom. The theorie…
Exact solutions to complex Type IIB supergravity for complex superalgebra and its real forms
Eric D'Hoker, Michael Gutperle, Christoph F. Uhlemann
We construct the general local solutions to complexified Type IIB supergravity which are invariant under the complexified Lie superalgebra . The geometry is a product of comp…
Solving SYM BCFT matrix models at large
Dongming He, Christoph F. Uhlemann
Many observables in 4d SYM with Gaiotto-Witten boundary conditions can be described exactly by matrix models via supersymmetric localization. The boundaries typicall…
