“…Finally, similar spacetimes have been recently studied in supergravity with negative cosmological constant. In particular, the resulting near-horizon geometry of branes wrapping spindles corresponds to a direct product of the type AdS × Σ where Σ is a spindle [72][73][74]. For instance, it is argued that the near-horizon limit of a M2-brane wrapped around a spindle is described by a well-known classical solution, the Plebanski-Demianski metric [75,76].…”

It has been argued that the entropy of de Sitter space corresponds to the entanglement between disconnected regions computable by switching on a replica parameter q modeled by the quotient dS/Z q . Within this framework, we show that the centrally-extended asymptotic symmetry algebra near the cosmic horizon is a single copy of the Virasoro algebra. The resulting density of states matches the semi-classical result of Gibbons and Hawking up to an undetermined constant that is chosen to reproduce the entanglement entropy previously found in the literature. It follows that the logarithmic quantum corrections to the Cardy entropy reproduces the known one-loop result computed in the bulk in the presence of a cutoff. The resulting entanglement entropy follows the divergent area law, where the UV cutoff is now a function of the replica parameter. Thus, as the near-horizon CFT fixes the cutoff in units of the Planck scale, the model can be viewed as a probe into whether the defect Hilbert space has a finite dimension; indeed, the limit q → 0, reproduces Banks' formula. We also study the quantum corrections of the effective description of the horizon entropy by means of Liouville field theory, where the large q limit corresponds to a realization of dS 3 /CFT 2 correspondence matching the logarithmic corrections to three-dimensional de Sitter space obtained by computing the one-loop contribution to the quantum gravity partition function in the round three-sphere.

“…They are also closely related to compactifications of the seven dimensional theory on spindles -two dimensional compact surfaces with conical deficits which have been studied extensively in the past two years (see e.g. [10][11][12][13][14][15]). Both constructions start with a ansatz AdS 5 × S 1 warped over a real coordinate.…”

In this note we present a solution of N = 4, d = 7 gauged supergravity which is holographically dual to a co-dimension two defect living in a six dimensional SCFT. The solution is obtained by double analytic continuation of a two charge supersymmetric black hole solution. The condition that no conical deficits are present in the bulk and on the boundary is satisfied by a one parameter family of solutions for which some holographic observables are computed.

“…Interestingly, these solutions realize the supersymmetry in different ways from very well studied topological twist in field theory, [2], and in gravity, [3]. It was first constructed from D3branes, [1,4,5], and then generalized to other branes: M2-branes, [6,7,8,9], M5-branes, [10], and D4-branes, [11,12]. Furthermore, two possible ways of realizing supersymmetry, topologically topological twist and anti-twist, were studied, [13,14].…”

We construct AdS 3 × Σ × Σ g and AdS 2 × Σ × Σ g solutions from M5-branes and D4-branes wrapped on a direct product of spindle, Σ, and Riemann surface, Σ g . Employing uplift formula, we obtain these solutions by uplifting the multi-charged AdS 3 × Σ and AdS 2 × Σ solutions to seven and six dimensions, respectively. We further uplift the solutions to elevendimensional and massive type IIA supergravity and calculate the holographic central charge and the Bekenstein-Hawking entropy, respectively.
