Quantum Physics I

This lecture covers the basics of Quantum Physics, focusing on harmonic oscillators and the Schrödinger equation. The instructor introduces creation and annihilation operators, eigenstates, and wave functions. The lecture explores the concept of parity operators, the quantization of energy levels, and the normalization of wave functions. Special attention is given to the case of a particle in a box, discussing the quantization of energy levels and the importance of boundary conditions. The lecture concludes with a detailed analysis of eigenstates and the discretization of energy levels in quantum systems.
