Near-extremal limits of de Sitter black holes

Autor: Alejandra Castro, Francesca Mariani, Chiara Toldo

Publikováno v: Journal of High Energy Physics, Vol 2023, Iss 7, Pp 1-34 (2023)

Abstract We analyze the thermodynamic response near extremality of charged black holes in four-dimensional Einstein-Maxwell theory with a positive cosmological constant. The latter exhibit three different extremal limits, dubbed cold, Nariai and ultr

On the search for multicenter AdS black holes from M-theory

Autor: Ruben Monten, Chiara Toldo

Publikováno v: Journal of High Energy Physics, Vol 2022, Iss 2, Pp 1-52 (2022)

Abstract We study the effective potentials for various probe branes surrounding AdS4 black holes with massive halos in consistent truncations of M-theory on the Sasaki-Einstein7 manifolds Q 111 and M 111. These probes are either M2 branes extended in

Bounds on multiscalar CFTs in the ε expansion

Autor: Matthijs Hogervorst, Chiara Toldo

Publikováno v: Journal of High Energy Physics, Vol 2021, Iss 4, Pp 1-36 (2021)

Abstract We study fixed points with N scalar fields in 4 − ε dimensions to leading order in ε using a bottom-up approach. We do so by analyzing O(N) invariants of the quartic coupling λ ijkl that describes such CFTs. In particular, we show that

Supersymmetric Rényi entropy and charged hyperbolic black holes

Autor: Seyed Morteza Hosseini, Chiara Toldo, Itamar Yaakov

Publikováno v: Journal of High Energy Physics, Vol 2020, Iss 7, Pp 1-40 (2020)

Abstract The supersymmetric Rényi entropy across a spherical entangling surface in a d-dimensional SCFT with flavor defects is equivalent to a supersymmetric partition function on ℍ d−1 × 𝕊1, which can be computed exactly using localization.

Rotating attractors and BPS black holes in AdS4

Autor: Kiril Hristov, Stefanos Katmadas, Chiara Toldo

Publikováno v: Journal of High Energy Physics, Vol 2019, Iss 1, Pp 1-51 (2019)

Abstract We analyze stationary BPS black hole solutions to 4d N $$ \mathcal{N} $$ = 2 abelian gauged supergravity. Using an appropriate near horizon ansatz, we construct rotating attractors with magnetic flux realizing a topological twist along the h

Deforming black holes in AdS

Autor: Gary T. Horowitz, Jorge E. Santos, Chiara Toldo

Publikováno v: Journal of High Energy Physics, Vol 2018, Iss 11, Pp 1-41 (2018)

Abstract We investigate how changes in the boundary metric affect the shape of AdS black holes. Most of our work is analytic and based on the AdS C-metric. Both asymptotically hyperbolic and compact black holes are studied. It has recently been shown

Partition functions on 3d circle bundles and their gravity duals

Autor: Chiara Toldo, Brian Willett

Publikováno v: Journal of High Energy Physics, Vol 2018, Iss 5, Pp 1-68 (2018)

Abstract The partition function of a three-dimensional N=2 $$ \mathcal{N}=2 $$ theory on the manifold ℳ g,p , an S 1 bundle of degree p over a closed Riemann surface Σ g , was recently computed via supersymmetric localization. In this paper, we co

Betti multiplets, flows across dimensions and c-extremization

Autor: Antonio Amariti, Chiara Toldo

Publikováno v: Journal of High Energy Physics, Vol 2017, Iss 7, Pp 1-29 (2017)

Abstract We consider 4d N $$ \mathcal{N} $$ = 1 SCFTs, topologically twisted on compact constant curvature Riemann surfaces, giving rise to 2d N $$ \mathcal{N} $$ = (0, 2) SCFTs. The exact R-current of these 2d SCFT extremizes the central charge c 2d

Rotating 5D black holes: Interactions and deformations near extremality

Publikováno v: SciPost Physics, 11(6):102. SciPost Foundation
SciPost Physics, Vol 11, Iss 6, p 102 (2021)

We study a two-dimensional theory of gravity coupled to matter that is relevant to describe holographic properties of black holes with a single rotational parameter in five dimensions (with or without cosmological constant). We focus on the near-hori
