The robustness of slow contraction and the shape of the scalar field potential
Timo Kist, Anna Ijjas
We use numerical relativity simulations to explore the conditions for a canonical scalar field minimally coupled to Einstein gravity to generate an extended phase of slow contr…

Numerical Relativity as a New Tool for Fundamental Cosmology
Anna Ijjas
Advances in our understanding of the origin, evolution and structure of the universe have long been driven by cosmological perturbation theory, model building and effective field t…

Rapidly Descending Dark Energy and the End of Cosmic Expansion
Cosmin Andrei, Anna Ijjas, Paul J. Steinhardt
If dark energy is a form of quintessence driven by a scalar field evolving down a monotonically decreasing potential that passes sufficiently below zero, the universe is…
