WebIn the 2016 experiment by Crossno et al. the electronic contribution to the thermal conductivity of graphene was found to violate the well-known Wiedemann–Franz (WF) law … The Dirac equation in the form originally proposed by Dirac is: [4] where ψ(x, t) is the wave function for the electron of rest mass m with spacetime coordinates x, t. The p1, p2, p3 are the components of the momentum, understood to be the momentum operator in the Schrödinger equation. See more In particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928. In its free form, or including electromagnetic interactions, it describes all spin-1⁄2 massive particles, … See more Pauli theory The necessity of introducing half-integer spin goes back experimentally to the results of the Stern–Gerlach experiment. A beam of atoms is run through a strong inhomogeneous magnetic field, which then splits into N parts … See more The Dirac equation is Lorentz covariant. Articulating this helps illuminate not only the Dirac equation, but also the Majorana spinor and Elko spinor, which although closely related, have … See more In its modern formulation for field theory, the Dirac equation is written in terms of a Dirac spinor field $${\displaystyle \psi }$$ taking values in a complex vector space described … See more The Dirac equation was also used (historically) to define a quantum-mechanical theory where $${\displaystyle \psi (x)}$$ is … See more Identification of observables The critical physical question in a quantum theory is this: what are the physically observable quantities defined by the theory?

WebMar 24, 2024 · Recently, a time-splitting Fourier pseudo-spectral (TSFP) scheme for solving numerically the Klein–Gordon–Dirac equation (KGDE) has been proposed (Yi et al., 2024). However, that paper only gives numerical experiments and lacks rigorous convergence analysis and error estimates for the scheme.
