Journey to the Center of a Quantized vortex
CNR-INOPeer-Reviewed Publication
Within an international collaboration, an experimental research team of LENS investigated vortex dynamics in strongly interacting superfluids using ultracold lithium gases. By precisely engineering and observing single quantized vortices, researchers uncovered how microscopic mutual friction governs superfluid dissipation. The study provides the first indirect experimental evidence of quasiparticles trapped in vortex cores, offering new insights relevant to superfluids, superconductors, and future quantum technologies.
