There has been a lot of interest in theories that modified Einstein gravity but which reduce to general relativity in certain limits. Such modified gravity theories predict the existence of a fifth force. There are severe constraints on fifth forces from solar system observations. However there has been a recent resurgence of interest in modified gravity theories with the advent of sophisticated screening mechanism whereby the fifth force is suppressed in the solar system but not necessarily beyond. The speaker will review some models of modified gravity and display the screening mechanism. She will then discuss how such models can be tested and constrained using laboratory experiments.

“Copernicus Webinar and Colloquium Series”: To promote scientific discussions during this pandemic, they are organizing an online seminar series, i.e. Copernicus Webinar Series, seeking the most outstanding speakers to introduce innovative ideas and important progress in the field of gravity and cosmology. This series is named after the famous Polish Astronomer, Nicolaus Copernicus, whose discovery eventually marked the dawn of modern science.
