The Department of Physics at the University of Jyväskylä, Finland, invites applications for a Doctoral Researcher position in Quantum Simulation, supervised by Assistant Professor Paolo Molignini. This 3.5-year PhD opportunity is embedded in the Quantum Simulation Theory group, which investigates quantum many-body systems, focusing on long-range and light-mediated interactions. The group leverages theoretical modeling, advanced simulations, and machine learning to study emergent quantum phenomena in ultracold atoms, molecules, and photonic devices, bridging condensed matter, computational, and quantum information physics. The research project centers on developing and applying theoretical and computational tools to explore quantum many-body phenomena beyond classical methods. Key topics include multiconfigurational methods for interacting fermions (with applications to dipolar and cavity-mediated systems), numerical simulations of ultracold bosonic systems (exploring supersolidity, quantum vortices, and analogies to neutron-star matter), and machine-learning-enhanced quantum simulation (optimizing measurement protocols, regression of observables, and data-driven characterization of quantum phases). The position offers access to excellent computational facilities, including the university cluster and national scientific computing resources. As a Doctoral Researcher, you will conduct basic research, develop and apply theoretical and computational methods, and present your findings in peer-reviewed journals and at international conferences. The role is ideal for candidates seeking expertise at the interface of quantum many-body theory, computational physics, and ultracold-atom experiments. The Department of Physics is a vibrant research environment, with strengths in materials physics, nuclear physics, and particle physics, and hosts an Academy of Finland Center of Excellence in Quark Matter. Experimental research is conducted in state-of-the-art facilities and in collaboration with international centers such as CERN and FAIR. Applicants must hold or be about to obtain a Master's degree in physics or a related field, with strong knowledge of quantum physics, statistical mechanics, or condensed matter physics. Proficiency in numerical methods and programming (Python, C++, or Fortran) is required. Experience with variational methods, exact diagonalization, tensor network methods, and machine learning models is an asset. High proficiency in English and excellent communication skills are essential. The successful candidate must be eligible for postgraduate studies at the University of Jyväskylä and will apply for study rights after selection. The university values diversity and encourages applications from women and underrepresented groups in STEM. The starting salary is approximately 2500 €/month (gross), with increases as thesis work progresses. The university offers a supportive, international, and multidisciplinary community, excellent working conditions, and a lively campus in the heart of Jyväskylä. Finland provides a high standard of living, free schooling, affordable childcare, and good family benefits. The application deadline is 31 December 2025. Applications must be submitted online and include a CV, motivation/cover letter, and degree certificate in English and PDF format.

The University of Jyväskylä’s Department of Physics invites applications for a Postdoctoral Researcher position in Condensed Matter Theory, focusing on the dynamics of driven-dissipative heterostructures and quantum engineered systems. This research is jointly supervised by Assistant Professor Paolo Molignini and Professor Tero Heikkilä, leaders of the Quantum Simulation and Condensed Matter Theory groups. The position is funded by the Finnish Quantum Flagship and will begin as early as January 2, 2026, for a fixed term of two years, with the possibility of extension to a third year. The successful candidate will investigate the interplay of topology, dissipation, and driving in engineered quantum systems. Research topics include non-equilibrium and Floquet topology, topological properties of density matrices and Liouvillians, non-Hermitian effects, and nonreciprocity in systems such as Josephson junctions and optomechanical platforms. Theoretical frameworks will involve open quantum systems described by Lindblad and Keldysh formalisms, complemented by numerical approaches such as exact diagonalization and tensor networks. Additional directions include studies of multi-terminal Josephson junctions, Andreev bound states with finite lifetimes, and links to quantum thermodynamics and driven-dissipative quantum heat machines. The Condensed Matter Theory group, led by Professor Heikkilä, is renowned for expertise in non-equilibrium superconductivity, quantum materials, and Josephson electronics. The Quantum Simulation Theory group, led by Assistant Professor Molignini, explores quantum many-body systems, long-range and light-mediated interactions, and emergent quantum phenomena in ultracold atoms, molecules, and photonic devices. Both groups offer access to advanced computational facilities, including the university cluster and national scientific computing centre CSC. Applicants must hold a doctoral degree in physics or a related field, with a thesis on a theoretical topic. Required skills include a strong foundation in condensed matter physics, quantum physics, and statistical mechanics. Experience with quantum master equations, Keldysh field theory, exact diagonalization, tensor network methods, and the theory of topological insulators and superconductors is considered an asset. High proficiency in English and excellent communication skills are essential. The PhD degree must be completed before the starting date. The university values diversity and encourages applications from women and underrepresented groups in STEM. The salary for this position is approximately 3600-4800 €/month (gross), depending on qualifications and experience, with a settling-in allowance for relocation. The university offers a vibrant campus, excellent research infrastructure, and a supportive international community. Jyväskylä is a major educational center in central Finland, known for its high standard of living, cultural scene, and opportunities for outdoor activities. To apply, candidates must have a working ORCID profile with public publications. Application documents (CV, cover/motivation letter, publication list, degree certificates) should be submitted in English and PDF format via the online application form by December 14, 2025. Applications sent via email will not be considered. For further information, contact Assistant Professor Paolo Molignini or Professor Tero Heikkilä. This position offers an excellent opportunity to contribute to cutting-edge research in quantum materials and simulation, within a collaborative and internationally recognized environment.
