We offer a 2.5 year contract for either a PhD student or a postdoctoral researcher (different conditions apply) to carry out research at the Center for Theoretical Condensed Matter Physics of the Universidad Autónoma de Madrid, under the supervision of the young group leader Miguel Bello. The focus of the project is to analyze the dynamics in different quantum impurity models and to see what analogies and differences can be established with conventional quantum emitter systems. The ideal candidate should have a background in quantum mechanics, and condensed matter physics, as well as strong mathematical and programming skills. Interested candidates for the PhD position should send their CV, transcript of their bachelor’s degree, and the name of at least one researcher who can be contacted for a reference letter to miguel.bello@uam.es. For the postdoctoral position, please send the CV, a list of publications, a letter of motivation, and the names of at least two researchers who can provide reference letters. All materials should be submitted by April 30, 2025. Any inquiries about the positions can be sent to the same address.
