Welcome to Chin Lab

 

Welcome to the ultracold atomic and molecular physics group in the Department of Physics and the James Franck Institute, at the University of Chicago. Here you will find a new and active research team exploring the quantum world at the lowest temperatures scientists can achieve, nearly a billionth of a degree Kelvin above absolute zero. Few sample images are shown in our Ultracold gallery. If you are interested in our research program or have any questions, please drop me a line, cchin @ uchicago.edu. I am looking forward to hearing from you!

Our paper, "Collective emission of matter-wave jets from driven Bose-Einstein condensates"  is published in Nature

We report an exciting observation that a rapid modulation of the interactions between atoms in a Bose-Einstein condensate leads to emission of atoms that forms jet structure. In the figure, the image on the far left is the original condensate, 15 micron in diameter. The 4 images on the right show the evolution of the sample during the emission process of about 20 ms.Click to see the videos of Bose Fireworks. More stories about this discovery see UChicago News.

Quantum Matter Synthesizer

Quantum Matter Synthesizer

The Quantum Matter Synthesizer (QMS) is a new experimental platform for quantum simulations and engineering new quantum phases. Once completed, the QMS will be able to load atoms into a far-detuned lattice projected through a high numerical aperture objective lens, image the atomic distribution and cool the atoms to the vibrational ground state, and then dynamically turn off and rearrange lattice sites to achieve the desired filling fraction and spin order. We will achieve this dynamically re-arrangeable lattice by forming our 2D optical potential with Digital Micromirror Devices (DMD).Read More
