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…

Using gravitational waves to see the first second of the Universe
Rishav Roshan, Graham White
Gravitational waves are a unique probe of the early Universe, as the Universe is transparent to gravitational radiation right back to the end of inflation. In this article, we summ…

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…
