Stationary Particle Creation and Entanglement in the Rotating Teo Wormhole: A Quantum Mode-Mixing Approach
Ramesh Radhakrishnan, Gerald Cleaver, William Julius
Rotating traversable wormholes allow the effects of frame dragging and rotation to be studied in the absence of event horizons. We develop a quantum field theoretic treatment of ma…

Scalar-Field Wave Dynamics and Quasinormal Modes of the Teo Rotating Wormhole
Ramesh Radhakrishnan, Gerald Cleaver, Delaram Mirfendereski +2
We investigate scalar field perturbations of the rotating Teo wormhole. We also compute the quasinormal mode (QNM) spectrum using first order WKB approximation. After separation of…

Gauge-Invariant Gravitational Wave Polarization in Metric f(R) Gravity with Cosmological Implications
Ramesh Radhakrishnan, David McNutt, Delaram Mirfendereski +4
We develop a fully gauge invariant analysis of gravitational wave polarizations in metric f(R) gravity with a particular focus on the modified Starobinsky model, whose constant cur…
