Summary of scientific research
Recent scientific activities center on the manipulation of matter with light, and its applications. This includes laser cooling of atoms; trapping of atoms in laser, magnetic, and microwave fields; the study of Bose-Einstein condensation of cold atomic gases; the quantum motion of atoms trapped in optical lattices, including the study of interacting, degenerate gases in one, two and three-dimensions; the study of collisions between lasercooled atoms and between atoms in a BEC, including photoassociative spectroscopy and the precision determination of atomic lifetimes and scattering lengths; the use of lasercooled atoms in atomic frequency standards, including atomic fountain clocks; atom optics and atom lasers - the study of coherent atomic deBroglie waves and their use in devices like interferometers; microgravity applications of laser-cooled atoms, including atomic clocks and atomic interferometry; atom lithography - the use of atom optics to write patterns on surfaces; optical tweezers - the use of laser beams to manipulate biological cells and other small objects - for studies of biochemical binding, bioadhesion, and other biochemical and biomedical applications; and quantum information, in which cold atoms are used as qubits.
