Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide.

Researchers from Würzburg and Dresden have for the first time experimentally demonstrated a quantum tornado.

Quantum vortex is created by orbital angular momentum -- electrons' circular motion around atomic nuclei.

Team hopes vortex-like behavior of electrons in momentum space could pave the way for new quantum technologies.

Physical Review X, 2025 ; 15 ( 1 ) DOI: 10.1103 /PhysRevX.15.011032.

Imaging Orbital Vortex Lines in Three -Dimensional Momentum Space in three -dimensional Momentum space is a new study.
