Themelia: the irreducible microstructure of black holes
Iosif Bena, Nejc Čeplak, Shaun D. Hampton +3
We argue that the fundamental "atomic objects" in string theory are themelia: extended objects that have 16 supersymmetries locally. We show that all existing smooth horizonless mi…
The (amazing) Super-Maze
Iosif Bena, Shaun D. Hampton, Anthony Houppe +2
The entropy of the three-charge NS5-F1-P black hole in Type IIA string theory comes from the breaking of F1 strings into little strings, which become independent mo…
Bootstrapping the effect of the twist operator in the D1D5 CFT
Bin Guo, Shaun Hampton
In the D1D5 CFT the twist operator of order 2 can twist together two copies in the untwisted sector into a single joined copy in the twisted sector. Traditionally, this effect is c…
Bootstrapping the effect of the twist operator in symmetric orbifold CFTs
Bin Guo, Shaun D. Hampton
We study the 2D symmetric orbifold CFT of two copies of free bosons. The twist operator can join the two separated copies in the untwisted sector into a joined copy in the twisted…
Linearizing the BPS Equations with Vector and Tensor Multiplets
Nejc Čeplak, Shaun Hampton, Nicholas P. Warner
We analyse the BPS equations of supergravity theory in six dimensions coupled to a vector and tensor multiplet. We show how these BPS equations can be reduced…
Entanglement Entropy and Phase Space Density: Lowest Landau Levels and 1/2 BPS states
Sumit R. Das, Shaun Hampton, Sinong Liu
We consider the entanglement entropy of an arbitrary subregion in a system of non-relativistic fermions in dimensions in Lowest Landau Level (LLL) states. Using the conne…
Resolving Black-Hole Microstructure with New Momentum Carriers
Iosif Bena, Nejc Ceplak, Shaun Hampton +3
All known horizonless black-hole microstate geometries correspond to brane sources that acquire a finite size, and hence break the spherical symmetry of the black hole. We construc…
