Quantum physics fundamentally redefines our understanding of nature by describing the behaviour of matter and energy at the smallest scales. Unlike classical theories, quantum mechanics reveals that ...

Atomic, molecular and optical physics lies at the intersection of quantum mechanics and electromagnetic theory, providing the fundamental framework for our understanding of matter and light.

The Physics World 2020 Breakthrough of the Year has been awarded to an international team for creating a silicon-based material with a direct band gap that emits light at wavelengths used for optical ...
