When you pop a tray of water into the freezer, you get ice cubes. Now, researchers from CU Boulder and the University of Toronto have achieved a similar transition using clouds of ultracold atoms. The findings provide a new window into materials that are hard to investigate in the laboratory.
New research at CU Boulder suggests that research on quantum states of matter could be conducted at room temperatures, thus facilitating cheaper and more widely available quantum technologies.
Konrad Lehnert joined JILA and NIST in January 2003, where his research group focuses on building electrical and electromechanical machines that can exhibit quantum behavior. The Lehnert Lab always asks, “What is the largest and most tangible object that can be in two places at once?”

A delicate balance between spin-orbit and other competing interactions inherent in 4d/5d materials offers a unique range of opportunities to uncover exotic states and physical properties that are intimately coupled to the crystal structure. This key characteristic provides us fertile ground to control quantum states by tuning the lattice of these materials. In this talk, we report our recent studies on electrical-current controlled phenomena in iridates and ruthenates, and our recent observation of a quantum liquid state in an un-frustrated square lattice.

The goal of the Simons Collaboration on Ultra-Quantum Matter is to fully develop the theory of UQM from fundamental characterization and classification to the design for realization and testing of UQM in the lab. To achieve this, the Collaboration will bring together experts in condensed matter physics, high energy physics, quantum information and atomic physics.

Quantum chemistry has reached a state where most physical properties of molecules can be easily and accurately calculated. However, the techniques behind these calculations afford no easy way of "making sense" of the computed quantities, like orbitals and wave functions. Learn how the Intrinsic Atomic Orbital (IAO) technique gives rise to partial charges and bond orders, and to bond orbitals, which represent the electron pairs of Lewis structures (σ- and π-bonds). Even curly-arrow reaction mechanisms can be readily derived!
