Description
Open quantum systems provide a framework to describe quantum systems interacting with their environments. The theory has been developed mainly in quantum optics and has recently found applications in various areas of physics, including condensed-matter physics, quantum information, high-energy physics, and cosmology. In this lecture, I will give an introduction to the theory of open quantum systems, focusing on the Lindblad master equation. After introducing its basic formulation, I will discuss general properties of Lindblad dynamics, such as the Liouvillian spectrum and stochastic unraveling. In the final part, I will show an application of the open quantum system approach to quarkonium evolution in relativistic heavy-ion collisions.
