El grupo de Termodinámica y Computación Cuántica les invita al siguiente seminario Fecha: Viernes 11 de Abril 2025 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 2: The Lindblad 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. Para quienes no puedan asistir, el seminario estará disponible en el canal de YouTube del grupo en unos días. https://www.youtube.com/@qtcg_ugr También os recordamos a todos la página web del Grupo, https://ic1.ugr.es/members/qtc/ donde se publicarán anuncios pasados, presentes y futuros. Nos vemos a todos allí DJM ________________________________________________________________________________ Dear all The Quantum Thermodynamics and Computation group cordially invites you to the following seminar Date: Friday 11 of April 2025 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, University of Granada) Title: Open Quantum Systems 2: The Lindblad Equation Abstract: 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.

Throughout the lecture, we will emphasize the physical meaning of these approximations and their range of validity. The seminar is accessible to undergraduate students, whom we strongly encourage to attend. For those unable to attend, the seminar will be available on the groups Youtube channel in a few days https://www.youtube.com/@qtcg_ugr We would also like to bring to your attention the groups web page https://ic1.ugr.es/members/qtc/ where you can find relevant material and information about past, present, and future seminars. See you all there DJM. --------------------------------------------------------- Dr. Michalis Skotiniotis Grupo de Termodinámica y Información Cuántica.
