Bulk-cone singularities and echoes from AdS exotic compact objects
Heng-Yu Chen, Yasuaki Hikida, Yasutaka Koga
The region near a black hole horizon may be modified by quantum gravity effects that resolve the singularity. Such geometry may be represented by an exotic compact object. Because…
AdS gravastar and its signatures from dual conformal field theory
Heng-Yu Chen, Yasuaki Hikida, Yasutaka Koga
Quantum gravity effects are expected to resolve the black hole singularity and the effects may deform the region near but outside the horizon. Applying AdS/CFT correspondence, we s…
AdS gravastar and bulk-cone singularities
Heng-Yu Chen, Yasuaki Hikida, Yasutaka Koga
The horizon of black hole is surrounded by the photon sphere and an outside observer cannot easily examine the geometry inside the photon sphere. In this note, we propose a way to…
Giant Gravitons and Volume Minimisation
Heng-Yu Chen, Nick Dorey, Sanefumi Moriyama +2
We establish a precise correspondence between the giant graviton expansion of the superconformal index of field theories in , and the master volume formalism of Gauntlett,…
The semi-classical saddles in three-dimensional gravity via holography and mini-superspace approach
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We determine the complex geometries dual to the semi-classical saddles in three-dimensional gravity with positive or negative cosmological constant. We examine the semi-classical s…
Semi-classical saddles of three-dimensional gravity via holography
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We find out the complex geometries corresponding to the semi-classical saddles of threedimensional quantum gravity by making use of the known results of dual conformal field theory…
