Uncovering the mystery of the disappearing molecules

Ultracold molecules are a research frontier that builds upon the many successes of ultracold atoms in the study of quantum science. There has been much experimental effort dedicated to the realization of trapped gaseous samples of ultracold molecules. In fact, various research groups from around the world have successfully demonstrated methods to bring samples of...

Controlled Collisions of Exactly two Ultracold Molecules

One of the fundamental questions in the study of ultracold polar molecules is “what happens when two molecules collide at ultracold temperatures?” Knowing whether the molecules undergo chemical reactions, form long lived complexes, change internal state, or bounce off each other carries important implications which will guide future research directions. Our recent experiment explores this...

Single molecules assembled and under control!

In a recent publication in PRL, we demonstrate the assembly of a single molecule with full quantum state control – including both internal and external states – starting from a single pair of atoms. Molecules, compared to their atom counterparts, generally possess a much richer internal structure and can interact with each other via long-range...

Single Molecule Results from the Ni Labs

Molecules are intrinsic coherent quantum system that have long been recognized as promising building blocks for quantum simulations, ideal natural laboratory to search for new physics, and a playground to answer fundamental questions in chemical reactions. Achieving full quantum control of molecules in bulk gases have been a forefront goal of the field that generally...

Ten Minute Talk:"Laser-cooled polyatomic molecules for electron EDM measurements" by Benjamin L. Augenbraun
Control and imaging of individually trapped ions and neutral atoms have been crucial to developing them as powerful quantum building blocks for qubits, logic gates, and clocks. Bringing these capabilities to molecules promises additional quantum applications, enabled by the rich internal degrees of freedom and inter-molecular coupling. I  will  present current experimental work at the...
