The FASTCORR project is performing well, showing substantial progress across multiple work packages and collaborations. The project has successfully advanced both fundamental theory and practical methodologies related to ultrafast dynamics in strongly correlated materials. Key developments have been achieved in areas such as quantum many-body systems, magnetic interactions, and optical spectroscopy. The collaboration between nodes has been fruitful, leading to innovative research outputs and over 110 publications in peer reviewed articles, many in high-profile journals such as Review of Modern Physics, Physical Review Letters, Nature and Science.
Key Highlights:
1. A significant achievement is the development of multidimensional spectroscopy techniques for strongly correlated materials, as published in Nature Photonics (2024). This collaboration between the Nijmegen and Hamburg groups shows how the optical response of correlated systems can be measured at sub-cycle IR timescales, revealing intricate many-body dynamics.
2. Uppsala University, in collaboration with other partners, has successfully integrated time-dependent density functional theory (TDDFT) with element-specific EUV probes. This combination allows for unprecedented precision in distinguishing same-site and intersite spin transfers in ultrafast spin dynamics, published in Science Advances (2023). This work enhances the understanding of energy-efficient spintronic devices.
3. The Hamburg node made substantial progress by implementing exact diagonalization techniques for non-equilibrium quantum dynamics. Although the system size limitations pose challenges, the developed methods are critical for evaluating time-dependent higher-order correlation functions in quantum systems.
4. The Nijmegen and Uppsala nodes collaborated on the study of quantum skyrmions and quantum Zeno effects in Heisenberg models. These findings contribute to the understanding of magnetic materials and the potential for quantum state manipulation of topologically protected states relevant for future technologies.
5. To study the complex dynamics in quantum quenches, the Hamburg and Nijmegen nodes has studied dynamics of fracton matter, demonstrating fractal wavefront formation. Additionally, the Hamburg and Nijmegen groups explored the amplification of superconductivity in fractal nanoflakes, providing a new perspective on unconventional superconductors.
6. The three nodes have condensed the long-standing research effort into magnetic interactions in solids and significantly expands on the theoretical framework for out-of-equilibrium situations in to a review article published in Reviews of Modern Physics (2023).
7. In collaboration with Radboud University, the project revealed insights into long-range magnetic order from spin glass behaviors, as published in Nature Physics (2022).
