Spontaneous Emission and Cross Section

Discusses the principles of laser operation, focusing on gain and absorption mechanisms essential for understanding light-matter interactions.

Explores the wave-particle dualism in quantum mechanics and the quantification of energy levels in atoms.

Explores time-independent perturbations in quantum mechanics and their effects on energy levels and eigenstates.

Analyzes bound-state problems, Bohr-Sommerfeld quantization, and tunneling through potential barriers in quantum mechanics.

Explains energy levels in quantum mechanics, including calculations with Planck's constant and electron charge.
