Compares symmetries in classical mechanics and Maxwell's equations, leading to the development of special relativity and exploring the concept of relative motion.
Explores the worldline action of a charged particle in Minkowski spacetime, covering 4-vectors, intervals, Lorentz invariance, and charged particles in EM fields.
Explores the instanton pre-factor and its interaction with electromagnetic fields, including the double well potential and nonperturbative energy splitting.
Explores photoabsorption, attenuation length, and subsequent processes, discussing the relationship between refractive index and absorption, electromagnetic fields, and important material properties.
