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...

Laser-cooling and Optical Trapping of Diatomic Molecules

Ultracold molecules have been proposed as a rich resource for many applications ranging from precision measurements and quantum metrology to quantum simulation and quantum information processing. The benefits of molecules in all these applications arise from the many internal degrees of freedom in a molecule. For example, even with the simplest diatomic molecules, one has...

Spin Transport in a Mott Insulator of Ultracold Fermions

Superconductivity is a phenomenon in materials whereby electron pairs can flow freely without resistance. As a consequence, no energy is lost while electrical current passes through the superconductor. The benefits, therefore, of superconducting materials which operate at room temperature are countless, and range from revolutionizing the electrical power transmission industry, to providing sweeping improvements in...

Improved Measurement of the Electron’s Electric Dipole Moment

Although the Standard Model of particle physics, one of the triumphs of modern physics, accurately describes all particle physics measurements made in laboratories so far, it is unable to answer many questions that arise from cosmological observations, such as the long-standing puzzle of why matter dominates over antimatter throughout the observable universe. To explain these...
