New frontiers with ultracold gases

Wolfgang Ketterle

This article summarizes recent work at MIT, which was presented at ICAP 2004. These examples demonstrate the broad range of topics, which are covered by research on quantum‐degenerate gases: boson and fermion mixtures, cold molecules, vortices, and interactions with surfaces.

Recently ground state polar molecules have been successfully realized using stimulated Raman adiabatic passage (STIRAP) technique, which has stimulated new experimental activities along this direction in many laboratories. It is very promising that a stable and quantum degenerate gas of polar molecules can be realized in the near future. Such polar molecules have a large permanent electric dipole moment and hence strong long-range dipolar interaction effects in the presence of an electric field, giving rise to new few- and many-body phenomena that are absent in the traditional atomic systems explored so far.Recently ground state polar molecules have been successfully realized using stimulated Raman adiabatic passage (STIRAP) technique, which has stimulated new experimental activities along this direction in many laboratories.

Ultracold chemistry and dipolar collisions in a quantum gas of polar molecules

Ultracold polar molecular quantum gases promise to open new research directions ranging from the study of ultra-cold chemistry, precision measurements to novel quantum phase transitions. Based on the preparation of high-phase space density gases of polar KRb molecules [1–3], I will discuss the control of dipolar collisions and chemical reactions of polar molecules in a regime where quantum statistics, single scattering partial waves, and quantum threshold laws play a dominant role [4]. In particular, I will point out the crucial role of electric dipole-dipole interactions [5] and external confinement [6] in determining the chemical reaction rate. Finally, I will discuss prospects of reaching quantum degeneracy in bialkali samples of polar molecules and prospects for these systems as novel dipolar quantum many-body systems.Ultracold polar molecular quantum gases promise to open new research directions ranging from the study of ultra-cold chemistry, precision measurements to novel quantum phase transitions.
