Recent developments in 3D gravity Niklas Johansson Vienna lunch club, Oct 14 based on work w/ Daniel Grumiller and Roman Jackiw
Outline • 3D gravity – hot or not? • Topologically massive gravity • Chiral gravity of Li, Song and Strominger – gravitons? • Logarithmic modes • Non-perturbatively • Summary and outlook
Outline Hot but problematic! • 3D gravity – hot or not? • Topologically massive gravity • Chiral gravity of Li, Song and Strominger – gravitons? • Logarithmic modes • Non-perturbatively • Summary and outlook New proposal! Is it stable? No.
