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…

A critical value of the inflationary tensor-to-scalar ratio from inhomogeneous inflation

Panagiotis Giannadakis, Matthew Elley, Raphael Flauger +1

We show that, for a given fixed value of the number of e-folds of the homogeneous solution, inflation succeeds with order unity inhomogeneities in the initial conditions above a ch…

Non-linear Dynamics and Primordial Black Hole Formation During Kination

Cheng Cheng, Panagiotis Giannadakis, Lucien Heurtier +1

We investigate the effects of large scalar inhomogeneities during the kination epoch, a period in which the universe's dynamics are dominated by the kinetic energy of a scalar fiel…

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…
