Normal modes of charged AdS solitons
Mengqi Lu, Ming Zhang, Robert B. Mann
We study massive charged scalar field perturbations in four- and five- dimensional charged anti-de Sitter soliton spacetimes. Appropriate boundary conditions are established via a…

Finite-cutoff Holographic Thermodynamics
Ming Zhang, Wen-Di Tan, Mengqi Lu +3
We develop a framework for holographic thermodynamics in finite-cutoff holography, extending the anti-de Sitter/conformal field theory (AdS/CFT) correspondence to incorporate a fin…

Existence of Vacuum Wormholes in Einsteinian Cubic Gravity
Mengqi Lu, Jiayue Yang, Robert B. Mann
Wormhole solutions in gravitational theories typically require exotic matter. Here we present a wormhole solution to the field equations of Einsteinian Cubic Gravity -- a phenomeno…
