Transportable optical clocks and open quantum systems with Sr atoms

Time keeping has been integral part of every civilisation. Today, optical clocks have reached into 10^-19 uncertainty regime. However, only very recently, transportable optical clocks have started to come into their existence. Transportable optical clocks are necessary and crucial step for utilising their full potential. In Birmingham, we are focussing on the transportability and unlocking applications including the idea of redefining SI second and quantum enabled radar. In the first part of my talk, I will give a brief overview of these efforts, while in the second part of the talk, I will introduce the idea of open quantum system based on the low-lying states of strontium. Such a system could be an interesting tool for studying many-body physics in optical lattices.
