Around a hollow darkness swirl the quanta, relentless and unceasing.
Swirling around a hole, a tornado of quantum particles starts to brew. They move without resistance, creating a current that flows unceasingly. Unlike macroscopic vortices in air, these microscopic quantum vortices can only spiral in specific ways: their circulation is quantized. Quantum vortices are an example of how an imperfection in the material, such as a hole, can produce fascinating phenomena. Can the shape of the material hint at new physics? Will this lead to new inventions one day?
