Parallel assembly of arbitrary defect-free atom arrays with a multi-tweezer algorithm
Weikun Tian, Wen Jun Wee, An Qu +4
Defect-free atom arrays are an important precursor for quantum information processing and quantum simulation. Yet, large-scale defect-free atom arrays can be challenging to realize…
Coherent seeding of the dynamics of a spinor Bose-Einstein condensate: from quantum to classical behavior
Bertrand Evrard, An Qu, Jean Dalibard +1
We present experiments revealing the competing effect of quantum fluctuations and of a coherent seed in the dynamics of a spin-1 Bose-Einstein condensate, and discuss the relevance…
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…
Relaxation and hysteresis near Shapiro resonances in a driven spinor condensate
Bertrand Evrard, An Qu, Karina Jiménez-García +2
We study the coherent and dissipative aspects of a driven spin-1 Bose-Einstein condensate (BEC) when the Zeeman energy is modulated around a static bias value. Resonances appear wh…
