If you have a question about this talk, please contact Prof Ian Kenyon.

I will discuss the QSNET project, that aims to build a network of atomic and molecular clocks in the UK to achieve unprecedented sensitivity in testing variations of the fine structure constant, α, and the electron-to-proton mass ratio, μ. This in turn will allow us to either discover that fundamental constants are actually not constant, or to provide more stringent constraints on a wide range of fundamental and phenomenological “new physics” models. These includes models of dark energy, ultra-light dark matter and grand unification models. The project currently includes the National Physical Laboratory, the University of Sussex, the Imperial College London, the University of Birmingham, and several international partners. I will discuss more in detail the plans of the Birmingham node, where we are building a clock based on highly charged ions of Californium, that is expected to improve our sensitivity to variations of α by orders of magnitude
