Quantum Mechanics: Path Integral Formulation

This lecture introduces the path integral formulation of Quantum Mechanics, starting from the double slit experiment and transitioning from the Schrödinger approach to the path integral. The path integral formulation offers advantages such as a clear interpretation of interference, manifest Lorentz invariance, and the ability to describe non-perturbative phenomena like instantons. The lecture covers the basics of Quantum Mechanics, the Copenhagen interpretation, and the key principles of the path integral formulation, emphasizing its connection with statistical mechanics and numerical methods.
