Dirac Equation: Solutions for Free Particles at Rest in Quantum Mechanics

Learn about the solution to the Dirac equation for an electron or positron at rest in vacuum through this 13-minute physics video. Explore the Dirac equation in momentum space, understand why Psi functions as a bispinor, and discover how Psi varies across space and time. Delve into eigenspinors, examine flag representations, and grasp the concept of spin state superposition. Reference the supplementary paper "An Introduction to Spinors" by Andrew M. Steane for deeper understanding of the quantum mechanical and relativistic concepts covered in this comprehensive exploration of particle physics.
