Coupled Dark Energy and Dark Matter for DESI: An Effective Guide to the Phantom Divide
Stefan Antusch, Stephen F. King, Xin Wang
Motivated by the recent Dark Energy Spectroscopic Instrument (DESI) DR2 preference for dynamical dark energy, we study interacting dark energy models in which a canonical quintesse…

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…
