PhD in Statistical Physics of Complex Systems (Joint Degree, Leipzig & Nancy)

This PhD programme in Statistical Physics of Complex Systems is a joint degree offered by Leipzig University in Germany and Université de Lorraine in Nancy, France, with additional collaboration from Coventry University (UK) and the National Academy of Sciences of Ukraine (Lviv). The programme focuses on a broad range of topics in statistical physics, including quantum phenomena, disorder effects on phase transitions, spin glasses, random graphs and networks, long-range interacting systems, topological excitations, and the conformational statistics of macromolecules such as polymers and proteins. Research also covers active polymeric systems, non-equilibrium relaxation, ice and water models, and quantum phase transitions. Students benefit from the combined expertise in analytical theory from Nancy and advanced computer simulation studies from Leipzig. The programme is designed to foster close collaboration between PhD students at both institutions, including extended research stays, joint seminars, and co-supervision. Final degrees are awarded by both universities under the 'co-tutelle de thèse' arrangement. Additional research stays at Coventry University and the Institute for Condensed Matter Physics in Lviv are possible, further enhancing the international dimension of the programme. Funding is available for extended research stays, with a flat rate of 700 EUR per month reimbursed. The programme is supported by binational grants, the Franco-German University, DAAD, CNRS, and the Alexander von Humboldt Foundation. There are no tuition fees, but students pay a semester contribution of approximately 195 EUR, which covers student services and mobility. The research training is flexible, individual, and problem-oriented, including workshops, conferences, symposia, literature seminars, summer/winter schools, tutoring, and transferable skills courses. All students are expected to spend time at partner universities, and the programme profits from the involvement of international partners. Career advisory services and support for international students are provided by the Graduate Academy Leipzig, including orientation events and arrival support. Applicants should hold a Master's or 'Diplom' degree in natural sciences and have knowledge of English. Basic German is helpful but not required. Applications are accepted at any time, and candidates should be prepared for international collaboration and research mobility. Accommodation options include student halls of residence and shared apartments. The supervisor-student ratio is close to 1:2 or even 1:1, ensuring structured research and supervision.
