Wormholes as perturbations of near-horizon black hole geometries: no-go theorems within effective field theories
Takamasa Kanai, Kengo Maeda, Daisuke Yoshida
We reformulate the construction of wormhole solutions as perturbations around near-horizon geometries of near-extremal Reissner-Nordström black holes in four dimensions and equal-a…
Semiclassical Rotating AdS Black Holes with Quantum Hair in Holography
Ryusei Hamaki, Kengo Maeda
In the context of the AdS/CFT duality, we study semiclassical stationary rotating AdS black holes with non-trivial quantum hair in three and five dimensions. We construct these sol…
Cutoff Scale of Quadratic Gravity from Quantum Focusing Conjecture
Takamasa Kanai, Kengo Maeda, Toshifumi Noumi +1
We derive the cutoff length scale of the quadratic gravity in dimensional spacetime by demanding that the quantum focusing conjecture for the smeared quantum expansion h…
The stability of the shell of D6-D2 branes in a supergravity solution
K. Maeda, T. Torii, M. Narita +1
The stability of the shell of wrapped D6-branes on K3 is investigated from the point of view of supergravity. We first construct an effective energy-momentum tensor for the shell u…
No-scalar hair conjecture in asymptotic de-Sitter spacetime
T. Torii, K. Meeda, M. Narita
We discuss the no-hair conjecture in the presence of a cosmological constant. For the firststep the real scalar field is considered as the matter field and the spacetime is assumed…
