SUMMARY:The Holographic dual of a finite energy shockwave
DESCRIPTION:Featuring Daliang Li\, Harvard University\n\nPart of the HET Se
	minar Series.\n\nTo understand holography\, it is important to know how CFT
	s encode finite deformations of the bulk metric. A great entry point to thi
	s problem is to study finite energy shockwaves\, which are simple and unive
	rsal. Even at finite deformations they preserve linearity in the equation o
	f motion. They are also insensitive to higher derivative corrections to gra
	vity. Their existence in gravity hints at a corresponding universal structu
	re in the way multi-stress tensor operators appear in the OPE. We find this
	 structure in CFT2 and show how it matches correlators computed holographic
	ally on a shockwave background in AdS3. We demonstrate that the CFT dual in
	volves multi light ray operators. We also discuss the implications in highe
	r dimensions.
