Counterterms, Kounterterms, and the variational problem in AdS gravity

G Anastasiou, O Miskovic, R Olea… - Journal of High Energy …, 2020 - Springer
A bstract We show that the Kounterterms for pure AdS gravity in arbitrary even dimensions
coincide with the boundary counterterms obtained through holographic renormalization if …

Impossible symmetries and conformal gravity

K Hinterbichler, A Joyce, G Mathys - Physical Review D, 2024 - APS
We explore the physics of relativistic gapless phases defined by a mixed anomaly between
two generalized conserved currents. The gapless modes can be understood as Goldstone …

Covariant action for conformal higher spin gravity

T Basile, M Grigoriev, E Skvortsov - Journal of Physics A …, 2023 - iopscience.iop.org
Conformal higher spin (HS) gravity is a HS extension of Weyl gravity and is a family of local
HS theories, which was put forward by Segal and Tseytlin. We propose a manifestly …

[HTML][HTML] BRST cohomology is Lie algebroid cohomology

W Jia, MS Klinger, RG Leigh - Nuclear Physics B, 2023 - Elsevier
In this paper we demonstrate that the exterior algebra of an Atiyah Lie algebroid generalizes
the familiar notions of the physicist's BRST complex. To reach this conclusion, we develop a …

Looking for partially-massless gravity

E Joung, K Mkrtchyan, G Poghosyan - Journal of High Energy Physics, 2019 - Springer
A bstract We study the possibility for a unitary theory of partially-massless (PM) spin-two field
interacting with Gravity in arbitrary dimensions. We show that the gauge and parity invariant …

[HTML][HTML] A novel signal representation in SEI: Manifold

Y Zhao, X Wang, L Sun, Z Huang - Journal of the Franklin Institute, 2023 - Elsevier
Specific emitter identification (SEI), as an important problem in situational awareness,
identifies emitters via unique characteristics. However, current SEI methods mostly suffer …

Topics in Weyl Geometry and Quantum Anomalies

W Jia - arXiv preprint arXiv:2407.02695, 2024 - arxiv.org
The first part of this thesis focuses on the Weyl-covariant nature of holography. We
generalize the Fefferman-Graham (FG) ambient construction for conformal geometry to a …

Casimir energy on the sphere and 6D CFT trace anomaly

R Aros, F Bugini, DE Diaz, C Núñez-Barra - Physical Review D, 2024 - APS
We elucidate the dependence of the Casimir energy on the trace anomaly coefficients for a
six-dimensional (6D) conformal field theory on R× S 5. This extends the universal …
