Conference Proceeding
Louko, J., & Toussaint, V. (2017). Unruh-DeWitt Fermion Detector on a (1+1)-Dimensional Cylindrical Spacetime: Arbitrary Worldlines and Inequivalent Spin Structures. In Proceedings of the 14th Marcel Grossmann Meeting on General Relativity (2809-2815). https://doi.org/10.1142/9789813226609_0349

We examine an Unruh-DeWitt particle detector which couples linearly to the scalar density of a massless Dirac field on the static cylindrical quotient of the (1+1)-dimensional Minkowski spacetime, allowing the detector’s motion to remain arbitrary and...

Quantum propagation across cosmological singularities (2017)
Journal Article
Gielen, S., & Turok, N. (2017). Quantum propagation across cosmological singularities. Physical Review D, 95(10), Article 103510. https://doi.org/10.1103/physrevd.95.103510

The initial singularity is the most troubling feature of the standard cosmology, which quantum effects are hoped to resolve. In this paper, we study quantum cosmology with conformal (Weyl) invariant matter. We show that it is natural to extend the sc... Read More about Quantum propagation across cosmological singularities.
