What is the Klein-Gordon Equation?
The Klein-Gordon Equation is a relativistic wave equation derived to describe the behavior of spinless particles in the framework of special relativity. Formulated by Oskar Klein and Walter Gordon in 1926, it was one of the first attempts to merge quantum mechanics with Einstein’s theory of relativity. The equation is given by:
∂²ψ/(∂t²) = c² ∇²ψ + (mc²/ℏ)² ψ
Here, ψ represents the wave function of the particle, c is the speed of light, m is the particle’s mass, and ℏ is the reduced Planck constant. This equation is essential for understanding particles like the pion and forms the basis for more advanced theories in quantum field theory.
