Early vs late string networks from a minimal QCD Axion
Journal of High Energy PhysicsWe propose a new regime of minimal QCD axion dark matter that lies between the pre- and post-inflationary scenarios, such that the Peccei-Quinn (PQ) symmetry is restored only on sufficiently large spatial scales.

Tree-level unitarity in Higgs inflation in the metric and the Palatini formulation
Journal of High Energy Physics, 2022 We calculate the tree-level amplitudes for electrically neutral 2 → 2 scattering for the Standard Model Higgs doublet non-minimally coupled to the Ricci scalar. We consider both the metric and the Palatini formulation of gravity. We find the partial wave

Savior curvatons and large non-Gaussianity
Journal of High Energy Physics, 2023 Curvatons are light (compared to the Hubble scale during inflation) spectator fields during inflation that potentially contribute to adiabatic curvature perturbations post-inflation.

Theism and Physical Cosmology [PDF]
, 2010 Physical cosmology purports to establish precise and testable claims about the origin of the universe. Thus, cosmology bears directly on traditional metaphysical claims -- in particular, claims about whether the universe has a creator (i.e. God).

Dark Radiation Constraints on Heavy QCD Axions
Journal of High Energy PhysicsThe naturalness problem of PQ symmetry motivates study of the heavy QCD axion, with masses m a > 1 MeV generated at scales above the QCD scale, and low values of the PQ symmetry breaking scale, f a .

Cosmology with the Laser Interferometer Space Antenna [PDF]
, 2023 The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and ...

Bias with a timer: axion domain wall decay and dark matter
Journal of High Energy PhysicsWe explore the interplay of the post-inflationary QCD axion and a light scalar field for the axion domain wall decay and dark matter (DM). The scalar field possesses a nonzero vacuum expectation value (VEV) during inflation, so that its interaction with ...

Hybrid inflation, reheating and dark radiation in a IIB perturbative moduli stabilization scenario
Journal of High Energy PhysicsWe study the cosmological implications of an effective field theory model derived within a configuration of D7 brane stacks in the framework of type-IIB string theory.
