General relativity and quantum mechanics are the twin pillars of modern physics, yet their unification remains one of the deepest open problems in science. This volume explores the fertile territory where these frameworks meet — the semiclassical frontier — asking what can be reliably calculated when quantum fields propagate on a curved background.

Quantum Field Theory in Curved Spacetime: An Introduction to Gravity’s Impact on the Double-Slit Experiment (with Arie Kapulkin) — DOI: 10.5772/intechopen.1012307

Derives closed-form expressions for gravitational phase shifts in quantum interference, finding Δϕ ≈ 2.7×10⁻²¹ rad for ⁸⁷Rb atoms in a 10-m orbital interferometer.
