Coupled-Channel Spectral Theory for a Non-Separable Rotating Geometry: Normal Modes and Two-Boundary Response in the Rotating AdS-Teo Wormhole
Ramesh Radhakrishnan, Gerald B. Cleaver, William Julius
We investigate scalar perturbations of a rotating asymptotically anti-de Sitter (AdS)Teo traversable wormhole with a controlled nonseparable angular deformation. The geometry retai…

A Review of Stable, Traversable Wormholes in f (R) Gravity Theories
Ramesh Radhakrishnan, Patrick Brown, Jacob Mutulevich +3
It has been proven that in standard Einstein gravity, exotic matter is required to stabilize traversable wormholes. Quantum field theory permits these violations due to the quantum…

Interference phenomena in the asymmetric dynamical Casimir effect for a single mirror
Matthew J. Gorban, William D. Julius, Ramesh Radhakrishnan +1
The interaction between the quantum vacuum and time-dependent boundaries can produce particles via the dynamical Casimir effect. It is known that, for asymmetric Casimir systems, t…
