An international group of physicists has traced the origin of an electromagnetic interaction to the Dirac equation, a fundamental equation of quantum physics. The interaction couples the spin of the ...

"Of all the equations of physics, perhaps the most magical is the Dirac equation." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. British ...

It might be possible to probe a close analogue of zitterbewegung by recreating the mathematics of Dirac's equation in a quantum wire. Dirac's equation has an infinite number of solutions with negative ...

This is a preview. Log in through your library . Abstract We investigate the convergence properties of a three-dimensional quantum lattice Boltzmann scheme for the Dirac equation. These schemes were ...

It is shown in the first part how the basic formalism of the theory of spin-orbit coupling in the band theory of crystals can be deduced at once from the Dirac equation without the usual ambiguities ...

The father of antimatter was the remarkable English physicist Paul Dirac (1902-1984), considered by many to be the greatest British theorist since Sir Isaac Newton. His research marked the first time ...

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 ...

Owing to its hexagonal lattice structure with a diatomic unit cell, graphene has low-energy electronic properties that are governed by the massless Dirac equation 6. This has a number of consequences, ...

Jim al-Khalili was sitting in a physics lecture at the University of Surrey when he suddenly understood the power of equations to describe and predict the physical world. He recalls that sadly his ...
