Schrödinger equation British  

noun

1. an equation used in wave mechanics to describe a physical system. For a particle of mass m and potential energy V it is written (i h /2π).(∂ψ/∂ t ) = (– h ²/8π² m )∇²ψ + Vψ, where i = √–1, h is the Planck constant, t the time, ∇² the Laplace operator, and ψ the wave function
