We are looking for master students to expand our team working towards the realization of a time crystal in a strongly coupled atom-cavity system. In analogy to spatial crystals, which break continuous translation symmetry, a time crystal is a non-equilibrium state of matter, which breaks continuous time translation symmetry. Its quantum state repeats periodically in time with a frequency that is robust against perturbations and quantum noise. To realize such a time crystal we need to pump our atom-cavity system with single mode radiation blue detuned with respect to the atomic transition. The master student should set up an ultrastable semiconductor laser system and implement it into the actual experimental set-up.
