Calibration of CMB Polarisation Using Cross-Experiment Correlations
Claire Rigouzzo, Eugene Lim, Susanna Azzoni +1
Parity-violating physics in the Universe can generate correlations between the Cosmic Microwave Background (CMB) - and -modes, but detecting such signals requires extremely a…
Polarisation Singularities of Gravitational Waves
Claire Rigouzzo, Sebastian Golat, Alex J. Vernon +3
Departure from idealised plane waves gives rise to intricate geometric structures in wave fields. One such structure is the polarisation singularity, which emerges when multiple mo…
On Non-Minimal Couplings to Gravity and Axion Isocurvature Bounds
Claire Rigouzzo, Sebastian Zell
For axions present during inflation, it has been shown that a non-minimal coupling of the inflaton to gravity worsens isocurvature bounds, while a non-minimal coupling …
No Dark Matter Axion During Minimal Higgs Inflation
Claire Rigouzzo, Sebastian Zell
We study minimal versions of Higgs inflation in the presence of a massless QCD axion. While the inflationary energy scale of the metric variant is too high to accommodate isocurvat…
PSALTer: Particle Spectrum for Any Tensor Lagrangian
Will Barker, Carlo Marzo, Claire Rigouzzo
We present the PSALTer software for efficiently computing the mass and energy of the particle spectrum for any (e.g. higher-rank) tensor field theory in the Wolfram Language. The u…
A decomposition of light's spin angular momentum density
Alex J. Vernon, Sebastian Golat, Claire Rigouzzo +2
Light carries intrinsic spin angular momentum (SAM) when the electric or magnetic field vector rotates over time. A familiar vector equation calculates the direction of light's SAM…
Coupling Metric-Affine Gravity to the Standard Model and Dark Matter Fermions
Claire Rigouzzo, Sebastian Zell
General Relativity (GR) exists in different formulations, which are equivalent in pure gravity. Once matter is included, however, observable predictions generically depend on the v…
Coupling Metric-Affine Gravity to a Higgs-Like Scalar Field
Claire Rigouzzo, Sebastian Zell
General Relativity (GR) exists in different formulations. They are equivalent in pure gravity but generically lead to distinct predictions once matter is included. After a brief ov…
