φenics: Vainshtein screening with the finite element method (2021)
Journal Article
Braden, J., Burrage, C., Elder, B., & Saadeh, D. (2021). φenics: Vainshtein screening with the finite element method. Journal of Cosmology and Astroparticle Physics, 2021(03), Article 010. https://doi.org/10.1088/1475-7516/2021/03/010

Within the landscape of modified theories of gravity, progress in understanding the behaviour of, and developing tests for, screening mechanisms has been hindered by the complexity of the field equations involved, which are nonlinear in nature and ch...

Experiment to Detect Dark Energy Forces Using Atom Interferometry (2019)
Journal Article
Sabulsky, D., Dutta, I., Hinds, E., Elder, B., Burrage, C., & Copeland, E. J. (2019). Experiment to Detect Dark Energy Forces Using Atom Interferometry. Physical Review Letters, 123(6), 1-6. https://doi.org/10.1103/PhysRevLett.123.061102

The accelerated expansion of the universe motivates a wide class of scalar field theories that modify General Relativity (GR) on large scales. Such theories require a screening mechanism to suppress the new force in regions where the weak field limit... Read More about Experiment to Detect Dark Energy Forces Using Atom Interferometry.
