PhD in A Recent Master In Experimental Ultracold Atom Or Trapped Ion Physics

Optical clocks have reached a precision of better than 10-18, which enables them to resolve the relativistic time dilation by only 1cm height difference in the gravitational field of earth. They are useful for searches of physics beyond the standard model, exploration of many-body physics, and societal applications, such as navigation./nYou will join a team building clocks that will overcome this limitation, effectively interrogating the atomic sample continuously. This enables reaching the ultimate precision already after just a few minutes, which is useful for many applications. We want to achieve this by creating clocks that can operate truly continuously, using technology that we have developed to achieve continuous Bose-Einstein condensation. We are building two types of such clocks: a superradiant clock and a zero-deadtime clock. A superradiant clock is a laser that lases on an ultranarrow optical transition. For the zero-deadtime clock, we supply atoms from a continuous ultracold Sr source to four clock interrogation zones that are in one vacuum chamber. With this PhD position you can contribute to both efforts.
