Title: Space-time crystals and spontaneous symmetry breaking in Bose-Einstein condensates

Abstract: In this talk I will recap the research on space-time crystals at the BEC Lab in Utrecht done in the past three years. I will give a short introduction to time crystals and describe the experiment performed, and the first observations of the space-time crystal in Utrecht. Subsequently, experimental methods were improved to come to a quantitative comparison between theory and experiment, studying both initial appearence of the space-time crystal pattern and the stable situation in the long-time limit. Finally, I discuss the latest results, studying the nature and dynamics of the broken symmetry involved in the formation of the space-time crystal.
