Abstract

The concept of scale (in-)dependence has become a fruitful paradigm across the natural and social sciences with many applications ranging from mathematics to finance and biology. In physics, one of the fascinating lessons in a quantum world is that the strength of interactions between particles becomes scale-dependent. Curiously, regimes where interactions become scale-independent offer the most direct link between microscopics and the macroscopic world. In this talk, I explain how the scale dependence of fundamental couplings can be exploited in new ways to search for theories beyond the Standard Model. I also discuss the prospect and challenges for scale invariance in quantum theories of gravity.
