Mechanics With Matlab: For...: Introductory Quantum

At the heart of quantum mechanics is the Schrödinger equation. While "pen-and-paper" solutions exist for simple systems like the harmonic oscillator or the hydrogen atom, most real-world quantum systems are analytically unsolvable.

Quantum mechanics is inherently non-intuitive. Concepts like electron probability clouds or quantum tunneling are difficult to grasp when presented solely as mathematical formulas. MATLAB’s robust plotting capabilities allow students to visualize these phenomena in real-time. For instance, rather than simply solving for the eigenvalues of a particle in a box, a student can use MATLAB to animate the wave-function as it evolves over time.

MATLAB excels at numerical integration and matrix manipulation. By discretizing space and representing the Hamiltonian operator as a matrix, students can use MATLAB’s built-in eigensolvers to find energy levels and stationary states. This "matrix mechanics" approach not only aligns with the fundamental principles laid out by Heisenberg but also prepares students for modern research in quantum chemistry and condensed matter physics.

Introductory Quantum Mechanics with MATLAB: A Computational Approach Bridging Theory and Application

By adjusting the height and width of the barrier in the code, they can observe how the transmission coefficient changes. Watching a wave packet split, with one part reflecting and another "leaking" through the barrier, provides a visceral understanding of the wave-particle duality. These simulations are foundational for understanding modern technology, from flash memory to scanning tunneling microscopes. Bridging Theory and Application
