In 1928, Dirac proposed his relativistic wave equation for electrons 33.This was a watershed event in theoretical physics, leading to a new understanding of spin, predicting the existence of ...

Dirac materials, named after the Dirac equation which describes the behavior of relativistic electrons, exhibit linear dispersion relations near these Dirac points, where the conduction and valence ...

The 1920s and 1930s were physics' heroic age. In the lecture halls and seminar rooms of central Europe, a cast of semi-legendary characters — Bohr, Heisenberg, Pauli, Schrödinger et al.
