Near extremal RN-AdS control of holographic Josephson transport
Ali Övgün, Reggie C. Pantig
We formulate a holographic weak-link construction in which Josephson transport is controlled by the charge sector of a Reissner--Nordstrom-AdS black brane. The model is an Einstein…
Josephson's effect in the Schwarzschild background
Reggie C. Pantig, Ali Övgün
We develop a fully covariant, analytic framework for Josephson phenomena in static curved spacetimes and specialize it to the Schwarzschild exterior. The formulation rests on two i…
Time-dependent black hole lensing from ringdown quasinormal mode
Reggie C. Pantig
Is it possible to find imprints of a black hole ringdown through gravitational lensing? To address this question, we formulate an analytic description of weak-field and strong-defl…
Shadow Ringing of Black Holes from Photon Sphere Quasinormal Modes
Reggie C. Pantig
The recent convergence of gravitational-wave (GW) observations and black hole imaging provides complementary probes of strong-gravity dynamics. While the black hole shadow is typic…
Gravitational Black Hole Shadow Spectroscopy
Reggie C. Pantig, Ali Övgün
In this work, we develop a generalized perturbative framework for gravitational shadows in static, spherically symmetric spacetimes. Building upon the recent two-parameter perturba…
