WebAbout the variational formulation of Schrödinger Equation. If by variational you mean, having a Lagrangian, the following Lagrangian does the job: $ \mathcal L = \frac {i\hbar} {2}\left (\psi^*\partial_t \psi - \psi \partial_t \psi^*\right) - \frac {\hbar^2} {2m}\left (\nabla \psi\right)\cdot \left (\nabla \psi^*\right) - V\psi^*\psi $
Derivation of the schrodinger equation
Did you know?
The Schrödinger equation is a linear partial differential equation that governs the wave function of a quantum-mechanical system. It is a key result in quantum mechanics, and its discovery was a significant landmark in the development of the subject. The equation is named after Erwin Schrödinger, who postulated the equation in 1925, and published it in 1926, forming the basis for the work that … WebJun 22, 2016 · Feynman's derivation of the Schrödinger equation In this article, the autor claims that Feynman derivation of the Schrödinger equation was a key aspect of the development of the Path integral approach to Quantum mechanics.
