Quantum corrected black hole microstates and entropy
Dongming He, Juan Hernandez, Maria Knysh
We extend the semiclassical black hole microstate construction to include quantum corrections to the microscopic entropy using a doubly holographic model of black holes. Specifical…
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…
Bulk quantum corrections to entwinement
Marius Gerbershagen, Dongming He
We determine corrections to a notion of generalized entanglement entropy known as entwinement dual to the length of a winding geodesic in asymptotically AdS geometries. W…
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…
