Robin holography in AdS and BTZ: double-trace RG flow and exceptional points
Yiru Wang, Juanyi Yang
We construct the exact Robin bulk-to-boundary propagator for a Breitenlöhner--Freedman scalar on AdS and the BTZ black hole, realizing the double-trace RG flow between stan…
Quasinormal Modes of Extremal Reissner-Nordstrom Black Holes via Seiberg-Witten Quantization
Yi-Rong Wang, Peng Yang, Kilar Zhang
We study the scalar perturbations of asymptotically flat extremal Reissner-Nordström black holes via the quantum Seiberg-Witten geometry of SU(2) gauge theory with…
Extended Heun Hierarchy in Quantum Seiberg-Witten Geometry
Peng Yang, Yi-Rong Wang, Kilar Zhang
We investigate the quantum geometry of the Seiberg-Witten curve for , linear quiver gauge theories. By applying the Weyl quantization prescription…
Holographic Reconstruction of Gravitational Perturbations in AdS/CFT and Implications for Celestial Conformal Field Theory
David A. Lowe, Yiru Wang, Juanyi Yang
We begin by reexamining the holographic reconstruction of scalar fields in four-dimensional anti-de Sitter spacetime, adopting a purely Lorentzian signature derivation, reproducing…
