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 ...

Three different quantum field theories deal with three of the four fundamental forces by which matter interacts: electromagnetism, which explains how atoms hold together; the strong nuclear force ...

2023年4月5日 · The ancient Greeks speculated that it might be air, fire or water. A century ago, physicists felt sure it was the atom. Today, we believe that the deepest layer of reality is populated by a ...

2024年12月24日 · Interacting with a quantum field usually changes its state, but Henrik Wilming at Leibniz University Hannover in Germany was looking for cases when this can be avoided. This led him to the idea of ...

2017年8月22日 · On 21 June, the Chinese Academy of Sciences hailed a breakthrough – a major upgrade to a kind of quantum device that measures magnetic fields. The announcement vanished after a journalist ...

2024年4月11日 · Higgs started that work at the University of Edinburgh in the UK in the 1960s. He was thinking about a branch of physics called quantum field theory, and in July of 1964, he took about a week to ...

2023年1月11日 · Read. Quantum Field Theory, As Simply As Possible is delivered with humour and erudition by Anthony Zee. What better way to get the little grey cells going than by unifying quantum mechanics and ...

2023年7月5日 · When you do that, you realise that the universe isn’t fundamentally made of separate parts at all, but is instead a single, quantum object. It is a radical idea, and one we are just beginning to ...

2008年11月20日 · The Higgs field is also thought to make a small contribution, giving mass to individual quarks as well as to electrons and some other particles. The Higgs field creates mass out of the quantum ...

2022年3月9日 · Also, according to quantum field theory, particles routinely pop into and out of existence. Tryon suggested that the same could happen for a universe. Keith Ross. Villembits, France.
