The Physics magazine of the American Physical Society (APS) has named the discovery of supersolidity in ultracold quantum gases as one of the top ten highlights of 2019. The research group led by Francesca Ferlaino has for the first time obtained evidence of supersolidity in erbium and dysprosium gases. Similar experiments were conducted in Pisa and Stuttgart.
Together with an international Consortium of six other research groups Francesca Ferlaino in collaboration with Peter Zoller successfully applied for funding of the project “MAQS” – Magnetic-Atom Quantum Simulator.
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.
