One of the most "magical" aspects of quantum mechanics is tunneling—the ability of a particle to pass through an energy barrier that would be impassable in classical physics. Using MATLAB, students can simulate a wave packet incident on a potential barrier.
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.

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. One of the most "magical" aspects of quantum
The transition from classical to quantum mechanics marks one of the most profound shifts in scientific history. While classical physics relies on deterministic paths, quantum mechanics introduces a world of probabilities, wave-functions, and operators. For many students, the leap from the intuitive physics of a bouncing ball to the abstract mathematics of the Schrödinger equation is daunting. This is where computational tools like MATLAB become indispensable. Solving the Schrödinger Equation Numerically
Introductory Quantum Mechanics with MATLAB: A Computational Approach
Visualizing the "probability density"—the square of the wave-function—helps students understand where a particle is most likely to be found. This visual feedback turns a static equation into a dynamic system, making the uncertainty principle a visible reality rather than just a theoretical constraint.
