Atomic, Molecular, and Optical Physics at UIUC.

What is AMO?

Researchers in atomic, molecular, and optical (AMO) physics study a diverse set of problems, ranging from the coldest objects in the universe to quantum entanglement to precision tests of the Standard Model. We also make practical contributions to many areas, including the most precise time and frequency standards and gyroscopes, methods for manipulating small objects such as biological cells or nanoparticles, and techniques for quantum cryptography to enable provably secure communication.

The coldest objects in the universe are atomic Bose-Einstein condensates.  Pictured here are three images, showing the momentum distribution of a gas of 87Rb atoms as it is cooled below the BEC transition temperature.  A peak appears at low momentum when there is BEC.

Quantum entaglement of photons can be created and controlled using optical techniques.  Shown here is the pattern, which looks like interlinked rings, of light produced from parametric downconversion.  The polarization state of photons that emerge where the rings overlap are entangled.

Professor Nayfeh works with silicon nanoparticles, which behave in some ways like molecules. Si nanoparticles are beginning to find use in microelectronics, optoelectronics and biomedical applications, and form one of the smallest lasers.

Professor Lev works with ultracold gases, cavity QED, and atom chips. His research focuses on developing novel laser cooling and trapping techniques to create ultracold samples of dipolar matter, which are then loaded onto micro- and nanofabricated atom chips for quantum information processing.
