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 ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String ...

Enrico Fermi had to cajole his friend Ettore Majorana into publishing his big idea: a modification of the Dirac equation that ... the creation of quantum field theory. It also inaugurated a ...

Quantum mechanics rules subatomic particles, while general relativity ... The theory also builds upon well-established principles in quantum field theory. It borrows from the Dirac-Kähler ...

A new theory links gravity to quantum entropy and introduces the G-field, possibly explaining dark matter and cosmic ...

with which he synthesized relativity and quantum theory to characterize the electron and, by extension, all the fundamental building blocks of matter. The prediction of the Dirac equation that the ...

At the heart of Dirac materials' unique properties is the Dirac cone, a linear dispersion of the electronic band structure near the Fermi level. This feature results in electrons moving through the ...
