The Quantum Barrier Potential - Quantum Tunneling

Explore the fascinating concept of quantum tunneling in this 22-minute video lecture on the quantum barrier potential. Delve into the mathematics behind this counterintuitive phenomenon, where particles can traverse barriers even when their energy is less than the barrier potential. Learn how this model applies to real-world scenarios, such as electrons encountering defects in wires. Build upon previous knowledge of the particle in a box problem to understand this second quantum problem, which involves a free particle encountering a finite potential barrier. Discover the weird yet mathematically sound principles that govern quantum tunneling and expand your understanding of modern physics concepts.
