Time Crystal Research Enters a New Phase

JQI researchers identified a set of promising ingredients for making time crystals. With those ingredients in mind, they developed a new theoretical framework that they hope will put time crystals research on an equal footing with the study of traditional phases of matter.

The central theme of my research is to apply tools from quantum science to the studies of molecular structures and chemical reactions. To this end, becoming a member of JQI, one of the world's leading quantum centers, is highly valuable for my research program. Conversely, I hope to leverage my interdisciplinary background in both AMO physics and physical chemistry to help foster synergy between quantum and chemical sciences at UMD.
