Abstract

Since its creation, the field of ultracold atoms has been through fantastic developments. Some of the most recent include the development of quantum-gas microscopes, atom tweezers, and various forms of interaction engineering. Each of these experimental advances has allowed new quantum phenomena to be accessed and observed. Further important development is based on the use of more exotic atomic species, whose peculiar atomic properties have allowed to broaden the horizons of investigation.

This talk aims to retrace the new opportunities that have emerged from the use of quantum gases composed of the strongly magnetic erbium and dysprosium atoms from the perspective of the Innsbruck experiments.

Thanks to their large magnetic moment, these species exhibit a large dipolar interaction that has allowed us to observe rotonic excitations, quantum droplets, and supersolid states. Moreover, their dense atomic spectrum has also made it possible to implement new optical manipulation schemes, and more recently the observation of a Hz-wide transition in the telecom frequency region promises new possibilities in quantum optics.

BIO

Francesca Ferlaino (born 1977) is a Professor of Physics at the University of Innsbruck (Austria), having moved there in 2007, with a past post-doc position at the University of Florence and LENS in Italy. She is currently Research and Managing Director at the Institute for Quantum Optics and Quantum Information (IQOQI) of the ÖAW, which is one of the most active centers for quantum science.

Her research activity explores quantum phenomena in atomic gases at ultralow temperatures with contributions spanning topics including the quantum matter of atoms and molecules and few-body and scattering physics. Over the last years, she focuses specifically on the strongly magnetic, and rather unexplored, Erbium and Dysprosium atomic species, realizing in 2012 the first worldwide Bose-Einstein condensation of Erbium, and in 2018 the first dipolar quantum mixture of Erbium and Dysprosium. In 2020, she was able to prepare the first long-lived supersolid state, an elusive and paradoxical state where superfluid flow and crystal rigidity coexist.

With these systems, she explored a variety of many-body quantum phenomena dictated by the long-range and anisotropic dipolar interaction among the atoms.

Her work has earned her multiple awards, including the prestigious Feltrinelli prize, the Grand Prix de Physique «Cécile-DeWitt Morette/École de Physique des Houches» from the French Academy of Science, the Junior BEC Award, and the Erwin Schrödinger Prize, the highest award of the Austrian Academy of Sciences. In addition, she is the recipient of an Alexander-von-Humboldt Professorship, and two ERC Grants (Starting and Consolidator).
