Logarithmic corrections to the entropy of near-extremal black holes in New Massive Gravity
Lucas Acito, Mariano Chernicoff, Julio Oliva +2
We study the one-loop correction to the entropy of near-extremal black holes in three-dimensional massive gravity at the special point where the theory exhibits a unique maximally…

From BTZ Perturbations to Schwarzian Modes: A Geometrical and Perturbative Analysis
Lucas Acito, MatÃas N. Sempé
We provide a detailed derivation of the Schwarzian modes in the full geometry of the Bañados-Teitelboim-Zanelli (BTZ) black hole at finite temperature, establishing the precise co…

Spinning fields on S and dS, UIRs and Ladder operators
Vasileios A. Letsios, MatÃas N. Sempé, Guillermo A. Silva
We construct, for spin tensor fields on S, a set of ladder operators that connect the distinct UIRs of SO. This is achieved by relying on the conformal Killing v…
