Cosmic Lockdown: When Decoherence Saves the Universe from Tunneling
Robson Christie, Jaewoo Joo, Greg Kaplanek +2
We investigate how quantum decoherence influences the tunneling dynamics of quantum fields in cosmological spacetimes. Specifically, we study a scalar field in an asymmetric double…
Inflation (2025)
John Ellis, Vincent Vennin, David Wands
This is a review article for The Review of Particle Physics 2026 (aka the Particle Data Book), appearing as Chapter 23. It forms a compact review of our understanding of cosmologic…
On the Hamilton-Jacobi approach to inflation beyond slow roll
Danilo Artigas, Emmanuel Frion, Tays Miranda +2
The Hamilton-Jacobi approach is a powerful tool to describe super-Hubble dynamics during cosmological inflation in a non-linear way. A key assumption of this framework is to neglec…
Quantum diffusion and large primordial perturbations from inflation
Vincent Vennin, David Wands
Quantum diffusion describes the inflow of vacuum quantum fluctuations as they get amplified by gravitational instability, and stretched to large distances during inflation. In this…
Stochastic inflation beyond slow roll: noise modelling and importance sampling
Joseph H. P. Jackson, Hooshyar Assadullahi, Andrew D. Gow +3
We simulate the distribution of very rare, large excursions in the primordial density field produced in models of inflation in the very early universe which include a strong enhanc…
Fast Radio Bursts and Artificial Neural Networks: a cosmological-model-independent estimation of the Hubble Constant
Jéferson A. S. Fortunato, David J. Bacon, Wiliam S. Hipólito-Ricaldi +1
Fast Radio Bursts (FRBs) have emerged as powerful cosmological probes in recent years offering valuable insights into cosmic expansion. These predominantly extragalactic transients…
