Open Quantum Systems 3: Resolving the Lindblad Master Equation
by Michalis Skotiniotis 06 May '25

06 May '25

El grupo de Termodinámica y Computación Cuántica les invita al siguiente seminario Fecha: Viernes 9 de Mayo 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 3: The Resolving the Lindblad Master 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 <https://urldefense.com/v3/__https://www.youtube.com/@qtcg_ugr__;!!D9dNQwwGX…> También os recordamos a todos la página web del Grupo, https://ic1.ugr.es/members/qtc/ donde se publicarán anuncios pasados, presentes y futuros.

In this work we propose an alternative decay mechanism via pair production of fermions in a simple extension of the ϕ4 model in which the scalar field is coupled to a (quantum) fermionic field through a Yukawa-like interaction. We study the power emitted through fermions as a function of the Yukawa coupling in the semi-classical limit (without backreaction), and compare it to the case of purely scalar radiation emission. > > > See you all there.
