The author presents a tutorial review of some ideas that are basic to our current
understanding of the phenomenon of Bose-Einstein condensation (BEC) in the dilute atomic …

This paper summarizes the experimental frontier of ultracold fermionic gases. It is based on
three lectures which one of the authors gave at the Varenna Summer School describing the …

Fermi gas with time-dependent pairing interaction hosts several different dynamical states.
Coupling between the collective BCS pairing mode and individual Cooper pair states can …

Optical lattice clocks with extremely stable frequency are possible when many atoms are
interrogated simultaneously, but this precision may come at the cost of systematic …

We present the first spatially resolved images of spin waves in a gas. The complete
longitudinal and transverse spin field as a function of time and space is reconstructed …

We have experimentally demonstrated the absence of spectroscopic resonance shifts in a
mixture of two interacting Fermi gases. This result is linked to observations in an ultracold …

We develop a theory on optical absorption in a dilute Bose-Einstein gas at low temperatures.
This theory is motivated by the Bogoliubov theory of elementary excitations for this system …

Recent experiments have measured collisional frequency shifts in polarized fermionic
alkaline-earth atoms using S 0 1-P 0 3 Rabi spectroscopy. Here, we provide a first-principles …

Exchange in a Boltzmann gas of bosons with several internal states leads to collective
transport of internal polarization. The internal dynamics can be understood as Larmor …

The development of a new and simplified system to create a Bose-Einstein condensate
(BEC) is presented; as well as experimental studies of two spin-state condensed and non …
