Generalised conditions for rapid-turn inflation
Raul Wolters, Oksana Iarygina, Ana Achucarro
Rapid-turn slow-roll inflationary trajectories have been shown to be an attractor in two-field models, provided the turn rate is near constant and larger than the slow-roll paramet…
The hand-made tail: Non-perturbative tails from multifield inflation
Ana Achucarro, Sebastian Cespedes, Anne-Christine Davis +1
It is becoming increasingly clear that large but rare fluctuations of the primordial curvature field, controlled by the tail of its probability distribution, could have dramatic ef…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
Cosmological Evolution of Semilocal String Networks
A. Achucarro, A. Avgoustidis, A. Lopez-Eiguren +2
Semilocal strings -- a particular limit of electroweak strings -- are an interesting example of a stable non-topological defect whose properties resemble those of their topological…
Orbital Inflation: inflating along an angular isometry of field space
Ana Achucarro, Yvette Welling
The simplicity of the CMB data, so well described by single-field inflation, raises the question whether there might be an equally simple multi-field realization consistent with th…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
