In collaboration with our theory colleague at IQOQI (Rick van Bijnen) we present a novel method for the analysis of quantum gas microscope images. Our method uses deep learning to improve the fidelity with which lattice sites can be classified as occupied or unoccupied. This method is able to improve upon the fidelity of threshold-based methods, following training on large data sets of simulated images. We demonstrate the effectiveness of the neural networks especially for the analysis of noncooled lattice images, as it is planned for our future Erbium quantum gas microscope. Here, low photon counts and atom movement limits the fidelity of traditional reconstruction techniques.
In a joint work from the RARE and ERBIUM team as well as our theory collaborator from IQOQI, Rick van Bijnen, we have observed hallmarks of supersolidity in dipolar quantum gases of Erbium and Dysprosium. Our work is highlighted in a Viewpoint article in Physics by T. Donner.
We have created for the first time a dipolar quantum mixture by combining two highly magnetic atomic species, Erbium and Dysprosium. The experiment has been conducted in the RARE Lab and we observe simultaneous quantum degeneracy of 5 Bose-Bose mixture and a Bose-Fermi one.
Claudia Politi, a PhD student in the RARE Lab, has won the first prize for best poster at ICAP 2018 in Barcelona.
More than 600 posters were presented during ICAP 2018. The prizes were decided by the Poster Awards Commission of ICAP 2018 presided by Prof. Fritz Haake.
After two months of holidays and travelling, Claudia Politi and Gabriele Natale came back to Innsbruck to start their PhD studies in the RARE and ERBIUM experiment.
