Yair is a PhD student in the Department of Chemical Physics at the Weizmann Institute of Science. In his research, Yair studies chemical and physical phenomena unique to extremely low temperatures. Contrary to the physics that we experience daily, at temperatures close to absolute zero the interactions between particles of matter are dominated by quantum mechanics, and atoms start behaving as waves. Yair uses experimental and computational tools borrowed from aerospace engineering to research and develop a novel cooling technique that would bring molecules to these temperatures. Using this method, he aims to observe the coldest chemical reactions ever identified on the molecular level, and even hopes to create new states of matter, very different from those familiar to us today.
