Overview: What began as simple technique
to be used for improved spectroscopy and precision measurement has blossomed
into a powerful tool for fundamental studies in low temperature physics. New
applications in matter wave interferometry, quantum degenerate gases, and
quantum information processing are now being actively pursued. The inventions
have lead to two Nobel Prizes in physics: 1997
(for atomic laser cooling) and 2001
(for Bose-Einstein condensation). This seminar is an introduction to theory
and experiment in laser cooling and trapping of neutral atoms and ions. A
series of lectures for ~7 weeks will be followed by student presentations
on contemporary research papers. Topics to be covered include:
• Basics of atom-photon interaction.
• Doppler cooling.
• Optical molasses and magneto-optic traps.
• Subdoppler polarization and polarization gradient
• Ion traps and resolved sideband cooling.
• Optical lattices.
