A Tale of Two Hartle-Hawking Wave Functions: Fully Gravitational vs Partially Frozen
Galit Anikeeva, Raphaël Dulac, Zixia Wei +1
We revisit the Hartle-Hawking wave function in AdS spacetime, where natural spatial slices are open and require an additional spacetime boundary. This leads to two constructions: a…
No boundary density matrix in elliptic de Sitter dS/
Raphaël Dulac, Zixia Wei
Elliptic de Sitter (dS) spacetime dS is a non-time-orientable spacetime obtained by imposing an antipodal identification to global dS. Unlike QFT on global dS, whose…
Zooming out of AdSSS: The Branes behind the CFT's
Iosif Bena, Antoine Bourget, Raphaël Dulac +2
We reveal the supersymmetric brane configurations that give rise to AdSSS supergravity solutions, which are holographic duals to three-dimensional CFT…
The local supersymmetries of a stack of branes
Raphaël Dulac, Yixuan Li
Local supersymmetries have been a guiding principle to construct smooth horizonless supergravity solutions. By computing brane densities from the brane low-energy effective action,…
Effervescent Spikes in M-theory
Iosif Bena, Raphaël Dulac, Dimitrios Toulikas +1
AdS S S solutions warped over a Riemann surface, , are indexed by a parameter, , that defines the superconformal algebra, $D(2,1; γ) \oplus D(2,1…
Effective Microstructure
Iosif Bena, Raphaël Dulac, Emil J. Martinec +3
In AdS/CFT duality, there are large families of smooth, horizonless microstate geometries that correspond to heavy pure states of the dual CFT. The metric and fluxes are co…
