El grupo de Termodinámica y Computación Cuántica les invita al siguiente seminario Fecha: Viernes 21, Marzo Hora: 12:00 am Lugar: Laboratorio de Fïsica Computacional, Dept de Electromagnetismo y Física de al Materia, Planta Baja, Facultad de Ciencias (junto al péndulo gigante) Ponente: Daniel Manzano (QTCG, Universidad de Granada) Titulo: Open Quantum Systems I. The Redfield equation. 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. El seminario es accesible para los estudiantes de grado, a los que recomendamos encarecidamente que asistan. Nos vemos a todos allí DJM ________________________________________________________________________________ Dear all The Quantum Thermodynamics and Computation group cordially invites you to the following seminar Date: Friday 21 March Time: 12:00 am Location: Computational Physics Laboratory, Department of Electromagnetism and Condensed Mater, Ground Floor, Faculty of Science (next to the giant pendulum) Speaker: Daniel Manzano (QTCG, Universidad de Granada) Title: Open Quantum Systems I.
