Semiclassical Approximations: WKB Method and Applications

Time-Independent Schrödinger Equation → Applications: Alpha Decay, Field Emission, and Cosmology

This learning path introduces the Wentzel–Kramers–Brillouin (WKB) approximation, a semiclassical method for solving the Schrödinger equation. Starting from the time-independent Schrödinger equation, the path covers the classical limit, the WKB wavefunction, connection formulas, barrier tunneling, and applications such as alpha decay, field emission, and bound-state quantization. The path is designed for high school students with a background in calculus and introductory quantum mechanics.
