Holographic shear correlators at low temperatures, and quantum
Alexandros Kanargias, Elias Kiritsis, Sameer Murthy +2
The strongly-coupled 3-dimensional theory, holographically dual to black branes at fixed chemical potential $\muext$ and temperature is considered in AdS Einstein-Max…
Near-extremal quantum cross-section for charged fields and superradiance
Panos Betzios, Olga Papadoulaki, Yanjun Zhou
We study the scattering and absorption properties of charged scalar fields on a near-extremal Reissner-Nordström black hole background. We show that in this low-temperature regime…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
Magnetic Anti-de Sitter Wormholes as seeds for Higgs Inflation
Panos Betzios, Ioannis D. Gialamas, Olga Papadoulaki
We show how certain types of magnetic asymptotically Anti-de Sitter Euclidean wormholes can catalyze the onset of inflation. These wormholes can be embedded as saddle point solutio…
Black Hole S-matrix for a scalar field
Panos Betzios, Nava Gaddam, Olga Papadoulaki
We describe a unitary scattering process, as observed from spatial infinity, of massless scalar particles on an asymptotically flat Schwarzschild black hole background. In order to…
Global symmetries, hidden sectors and emergent (dark) vector interactions
Panagiotis Betzios, Elias Kiritsis, Vasilis Niarchos +1
Hidden theories coupled to the SM may provide emergent (dark) vectors, that are composites/bound-states of the hidden fields. This is motivated by paradigms emerging from the AdS/C…
