Production and characterization of a fragmented spinor Bose-Einstein condensate
Bertrand Evrard, An Qu, Jean Dalibard +1
Understanding the ground state of many-body fluids is a central question of statistical physics. Usually for weakly interacting Bose gases, most particles occupy the same state, co…

From many-body oscillations to thermalization in an isolated spinor gas
Bertrand Evrard, An Qu, Jean Dalibard +1
The dynamics of a many-body system can take many forms, from a purely reversible evolution to fast thermalization. Here we show experimentally and numerically that an assembly of s…

Probing spin correlations in a Bose-Einstein condensate near the single atom level
An Qu, Bertrand Evrard, Jean Dalibard +1
Using parametric conversion induced by a Shapiro-type resonance, we produce and characterize a two-mode squeezed vacuum state in a sodium spin 1 Bose-Einstein condensate. Spin-chan…
