Seminario | Open Quantum Systems I. The Redfield equation.

Seminario del grupo de Termodinámica y Computación Cuántica, impartido por Daniel Manzano (QTCG, Universidad de Granada). El seminario es accesible para los estudiantes de grado, a los que recomendamos encarecidamente que asistan.

Resumen:

In this lecture, we will introduce the problem of Open Quantum Systems within the Markovian framework, a crucial approach for understanding dissipation and decoherence in quantum mechanics. We will begin by considering the full quantum dynamics of a composite system consisting of a subsystem of interest coupled to an environment. By systematically applying a series of approximations—such as weak coupling, Born, and Markov approximations—we will derive an effective equation of motion that governs the reduced dynamics of the subsystem. This will allow us to describe irreversible processes and the loss of quantum coherence in a controlled manner. Throughout the lecture, we will emphasize the physical meaning of these approximations and their range of validity.
