Curvaton-assisted hilltop inflation
Wen-Yuan Ai, Stephen F. King, Xin Wang +1
Following the recent Atacama Cosmology Telescope (ACT) results, we consider hilltop inflation where the inflaton is coupled to a curvaton, simultaneously addressing two main challe…
Cosmological Consequences of Domain Walls Biased by Quantum Gravity
Yann Gouttenoire, Stephen F. King, Rishav Roshan +3
One of the simplest standard model extensions leading to a domain wall network is a real scalar with a symmetry spontaneously broken during universe evolution. Motivated…
Modular domain walls and gravitational waves
Stephen F. King, Xin Wang, Ye-Ling Zhou
We discuss modular domain walls and gravitational waves in a class of supersymmetric models where quark and lepton flavour symmetry emerges from modular symmetry. In such models a…
Modular Invariant Hilltop Inflation
Stephen F. King, Xin Wang
In this paper we show that it is possible to achieve successful hilltop inflation in which the inflaton is identified as the modulus field in a modular invariant theory. The dilato…
Quantum Gravity Effects on Fermionic Dark Matter and Gravitational Waves
Stephen F. King, Rishav Roshan, Xin Wang +2
We explore the phenomenological consequences of breaking discrete global symmetries in quantum gravity (QG). We extend a previous scenario where discrete global symmetries are resp…
Modulus stabilisation in the multiple-modulus framework
Stephen F. King, Xin Wang
In a class of modular-invariant models with multiple moduli fields, the viable lepton flavour mixing pattern can be realised if the values of moduli are selected to be at the fixed…
