Fourier imaging of collective spontaneous emission modes in superradiant cold atomic clouds
Adrien Gavalda, Guillaume Tremblier, Martin Poitrinal +3
We measure the spatial pattern associated with the superradiant emission from a cloud of cold 87Rb atoms using Fourier imaging. We observe a highly directional, ring-shaped emissio…

Microwave spectroscopy and multi-channel quantum defect analysis of ytterbium Rydberg states
Rin Kuroda, Vernon M. Hughes, Martin Poitrinal +2
The complex Rydberg structure of ytterbium atoms is shaped by multiple low-lying ion-core-excited states and strong channel interactions, which presents both opportunities and chal…

Ultra-precise holographic optical tweezers array
Yuki Torii Chew, Martin Poitrinal, Takafumi Tomita +4
Neutral atoms trapped in microscopic optical tweezers have emerged as a growing platform for quantum science. Achieving homogeneity over the tweezers array is an important technica…
