Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...

Einstein and the Quantum Revolutions Alain Aspect Univ. Chicago Press (2024) French physicist Alain Aspect is a pioneer in ‘quantum entanglement’ — connections between the quantum properties of ...

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

What happens when matter transitions from one phase to another—a solid to a liquid or a liquid to a gas? Describing these critical points precisely, in solvable mathematical terms, is no simple feat.

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...
