Quantum Stochastic Inflation
Robson Christie, Jaewoo Joo, Greg Kaplanek +2
We formulate stochastic inflation in an open quantum system framework. The field coarse-grained in a patch of fixed physical size, and the total momentum of that patch, form a cano…
UV artefacts in ultra-slow-roll models of inflation
Gerald Barnert, Laura Iacconi, Hooshyar Assadullahi +2
Within single-field inflation, primordial black hole and scalar-induced gravitational wave production from enhanced primordial perturbations typically requires a transient non-attr…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
Closing in on -attractors
Laura Iacconi, Sukannya Bhattacharya, Matteo Fasiello +1
Recent observations of cosmic microwave background (CMB) anisotropies combined with large-scale structure may point towards higher values of the scalar spectral index, . This…
Novel CMB constraints on the parameter in alpha-attractor models
Laura Iacconi, Matteo Fasiello, Jussi Väliviita +1
Cosmological -attractors are a compelling class of inflationary models. They lead to universal predictions for large-scale observables, broadly independent from the functional f…
Non-perturbative non-Gaussianity and primordial black holes
Andrew D. Gow, Hooshyar Assadullahi, Joseph H. P. Jackson +3
We present a non-perturbative method for calculating the abundance of primordial black holes given an arbitrary one-point probability distribution function for the primordial curva…
