Levitating Nanoparticles in Vacuum: A Quantum Treasure Trove.
Speaker: Prof. Oriol Romero-Isart from Institute of Quantum Optics and Quantum Information (IQOQI) at the University of Innsbruck, Austria.
ABOUT THE SPEAKER: Oriol Romero-Isart research interests deal with theoeretical quantum optics, atomic physics, nanophysics, and superconductivity in the context of quantum science: quantum information processing, quantum simulation, quantum metrology and foundations of quantum mechanics. Proposing cutting-edge experiments in close collaborations with experimental groups is also a focus of interest
Levitating Nanoparticles in Vacuum: A Quantum Treasure Trove
ABSTRACT: A tiny nanometer-sized piece of glass, diamond, metal, superconductor, or magnet, can be levitated in high vacuum and hence be highly isolated from the environment. Such an experimentally possible scenario establishes a new paradigm for quantum physics. The motion of unprecedented massive objects can be brought to the quantum regime, thereby allowing the possibility to prepare large quantum superpositions that challenge the foundations of quantum mechanics. Furthermore, these isolated nanoparticles allow to probe their internal quantum many-body physics in a unique closed scenario that can be pushed to extreme regimes (a nanoparticle rotating at velocities close to disintegration), a possibility that opens the door to discover new phenomena in condensed-matter physics. In this colloquium, we will review this active research field by including on-going experiments and the most ambitious current theoretical research directions.
