Researchers from Würzburg have experimentally demonstrated a quantum tornado for the first time by refining an established method. In the quantum semimetal tantalum arsenide (TaAs), electrons in ...

Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide. A team of researchers from Würzburg has for ...

In the 1990s, the realization that helical beams carry orbital angular momentum started the field of structured light. In 2024, experiments showed that these beams preserve their phase information ...

Light can be tailored to carry angular momentum well beyond the restriction of its two spin states, left- and right-circularly polarized light, by imbuing it with orbital angular momentum (OAM). OAM ...

Scientists experimentally confirm electron vortices in momentum space, a quantum phenomenon that could enable efficient, low-energy quantum technologies. (Nanowerk News) A breakthrough that’s turning ...
