Título: Supersolidity in the ultracold: when quantum gases behave as crystal and superfluid at the same time

Conferenciante: Prof. Francesca Ferlaino (Universität Innsbruck & Institute for Quantum Optics and Quantum Information (IQOQI), Austrian Academy of Science, Austria)

Fecha y hora: Martes 18 de Junio del 2024 a las 16:00

Lugar: Aula Magna, Facultad de Ciencias

Resumen: Quantum physics frequently gives rise to conceptual paradoxes that defy our classical intuition. In many-body quantum systems, interactions are key, especially when they dominate over kinetic energy. Their form and strength crucially define the existing strongly-correlated quantum phases of matter and dictate phenomena beyond the classical regime. Dipolar interactions, particularly relevant in strongly magnetic atoms, are fundamentally distinct from the typical van der Waals interactions in neutral atoms. Their orientation-dependence and non-locality enable the emergence of novel phases of matter, from ultra-dilute quantum droplets to supersolid phases in which macroscopically coherent quantum gases self-organize in space to produce ordered density wave with energy cost approaching zero. This talk will retrace the new phenomena, which have been observed with quantum degenerate gases of erbium and dysprosium atoms from the perspective of the Innsbruck experiments.
