Quantum backreaction for overspinning btz geometries

HIGHLIGHTS

• who: Olaf Baake from the CentroUniversidad de Talca have published the paper: Quantum backreaction for overspinning BTZ geometries, in the Journal: (JOURNAL) of 19/01/2023
• what: The authors examine the semiclassical backreaction of a conformally coupled scalar field on an overspinning (Bau00f1ados-Teitelboim-Zanelli) BTZ geometry. The authors show that the stress-energy tensor is nonrenormalizable in this approach and consequently the perturbative solution to the semiclassical equations in the overspinning case does not exist.
• how: The interesting aspect of this result is that the quantum fluctuations of a conformally coupled scalar . . .
