LEGO Interferometers Bring Quantum Physics to Life

2025-02-25

Researchers at the University of Nottingham have developed LEGO-based interferometer kits to make quantum science more accessible. These hands-on kits, designed for secondary school students and beyond, replicate professional optical equipment, allowing students to build and experiment with lasers, mirrors, and beamsplitters to observe interference patterns. The project, 'Photon Bricks,' has been a hit at exhibitions, with participants praising its engaging approach to complex concepts. The kits are designed to inspire the next generation of scientists and are currently being rolled out to schools in Nottingham and Cardiff.

Nottingham Scientists Discover New Type of Magnetism with Potential to Revolutionize Digital Devices

2024-12-16

Researchers at the University of Nottingham have discovered a new class of magnetism called 'altermagnetism,' where magnetic building blocks align antiparallel but with a rotated structure. Published in Nature, this finding could revolutionize digital devices. Altermagnets promise a thousand-fold increase in the speed of microelectronic components and digital memory, while offering improved robustness and energy efficiency, and reducing reliance on rare and toxic heavy elements. The team used X-ray imaging at the MAX IV facility in Sweden to confirm the existence and controllability of this new magnetic order.
