Optical Bloch Equations

This lecture covers the derivation and stationary solutions of Optical Bloch Equations for a two-level quantum system in the presence of an environment. It discusses the coherent and incoherent effects, as well as the justification of the model. The lecture also explores the concept of quantum trajectories and the interpretation of quantum dynamics. Additionally, it delves into the concept of saturation and the role of classical harmonic oscillators in the system. The presentation concludes with a discussion on the inclusion of other processes, such as dephasing, in the system.
