• Quantum field theory in curved spacetime

• Black hole thermodynamics and semiclassical gravity

• Cosmological particle production and accelerated expansion

We study quantum field theory in non-inertial frames and curved spacetime, with emphasis on particle creation, spectral structure, and exact analytic models of radiation. Our work analyzes how acceleration, geometry, and boundaries influence particle spectra, energy flux, and the operational meaning of particles.

Our research engages general relativity primarily through black hole spacetimes and their analogues. We study black hole thermodynamics by analyzing quantum fields on curved backgrounds, including Hawking temperature, extremal geometries, and the quantum atmosphere outside horizons. Analytic methods are used to understand how curvature and acceleration generate radiation.

Our cosmological work analyzes particle production in expanding spacetimes as a dynamical analogue of accelerating mirror systems. By expressing cosmological acceleration through the Schwarzian derivative, we study how expansion histories and causal structure constrain cosmological evolution, including scenarios that may require turnaround behavior.

We investigate how thermodynamic structure emerges from accelerated motion and gravitational-like effects on quantum fields.  Topics include acceleration radiation, Unruh-like effects, thermal features in beta decay, and kinematic Planckian spectra.
