Introduces Quantum Field Theory as the way to reconcile Quantum Mechanics with Relativity, emphasizing the need for a local field due to the impossibility of instantaneous interactions at a distance.
Delves into the variational method in relativistic quantum field theory without cutoff, emphasizing weakly entangled states and the transition to relativistic continuous matrix product states.
Covers conservation of momentum, electromagnetic fields, relativistic energy-momentum, intensity definitions, and practical examples of solar emissions.
