Sorting superfluidity from Bose-Einstein condensation in atomic gases

Iacopo Carusotto

We propose a method to measure the superfluid fraction of an atomic gas.The method involves the use of a vector potential generated by optical beams with nonzero angular momenta to simulate uniform rotation.The induced change in angular momentum of the atomic gas can be measured spectroscopically.This allows a direct determination of the superfluid fraction.

Bose–Einstein condensation

M. Inguscio, L. Fallani

Besides the enormous opportunities offered by spectroscopy and atom interferometry, laser cooling has opened up the possibility of experimentally realizing and manipulating quantum degenerate gases: Bose–Einstein condensates and degenerate Fermionic systems. This chapter starts with an illustration of key experimental techniques, such as magnetic trapping, evaporative cooling, and Feshbach resonances. It then turns to the physics of atomic Bose–Einstein condensates, discussing their superfluid behaviour, their coherence properties, and their application to precise measurements. It also describes the experimental investigation of ultracold Fermi gases and fermionic superfluidity, as well as ongoing research into ultracold polar molecules.Besides the enormous opportunities offered by spectroscopy and atom interferometry, laser cooling has opened up the possibility of experimentally realizing and manipulating quantum degenerate gases: Bose–Einstein condensates and degenerate Fermionic systems.
