Research Summary:
In our labs we have three principal directions of research:
- We investigate the dynamics of ultracold atoms confined in an “optical lattice”, for applications in nanolithography and quantum computing. An “optical lattice” consists of atoms at temperatures of few microKelvins organized in crystal-like fashion in periodic potential wells induced by the interference of several laser beams. The depth, shape, and spacing of the wells can be adjusted by varying laser intensity, polarization, and frequency. Our immediate goals are to investigate Non-Brownian Random Walks and Radiation Trapping in an optical lattice.
- We investigate the phenomena of electromagnetically induced transparency and electromagnetically induced absorption in atomic vapors, for application in the “slowing” and storage of light inside an atomic medium.
- We investigate the refractometry of turbid media (i.e., non-transparent, highly scattering media such as milk, animal tissue, petroleum products) for bio and environmental sensing and other applications.
