Physicists have used a cutting-edge quantum computer to simulate a complex particle theory in two dimensions. Unlike ...

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 ...

Albert Einstein’s special theory of relativity, which explains what happens when things move very fast – to create what are known as quantum field theories. Three different quantum field ...

It was only in 1927, when Dirac formulated a quantum theory of the electromagnetic field, that it was finally understood how such ‘spontaneous decay’ worked in terms of the new theory 6.

CFT stands for conformal field theory, which describes quantum physical systems whose properties are the same at all spatial distances. "This sounds very complicated at first, but it's easy to ...
