Center for Theoretical Physics of Polish Academy of Sciences (CTP PAS) will be opening a fully funded PhD position within the doctoral school Warsaw4PhD, with a start date of October 1st, 2024. We will be looking for a candidate to join the project "Studies of Spectrum Broadcast Structures in Quantum Open Systems Models", carried on at CTP and financed by National Science Center (NCN). The principal investigator is dr Jarek Korbicz. The project combines modern open quantum systems theory, quantum information, and foundations of quantum mechanics. We are looking for a candidate with a solid theoretical knowledge of quantum mechanics and enthusiastic about working on quantum foundations and quantum information theory. The main task within the project is to conduct theoretical investigations of advanced forms of quantum-to-classical transition and decoherence such as Spectrum Broadcast Structures and quantum Darwinism in various open systems models and write a doctoral thesis based on them. The project starts on October 1st, 2024 with the duration of 4 years. Further details of the project will appear mid-April 2024 under the link: http://warsaw4phd.eu/en/candidates/research-projects/, tab “Center for Theoretical Physics PAS”. The application process will start on May 20, 2024. Please monitor: https://warsaw4phd.eu/en/admissions/ for up-to-date information about the admission process.
