When its ice and freezing cold At very low temperatures, nature behaves very different than at high temperatures. The laws of quantum mechanics will apply, dictating that matter starts behaving like waves rather than particles. In this project, the researchers will develop methods to collide molecules at extremely low temperatures of 10 mK. This will result in bizarre phenomena, which have been predicted theoretically but remain elusive experimentally. The researchers will visualize these effects using dedicated laser detection and imaging techniques.
