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…
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; γ…
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…
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,…
