Precise control over the coupling between spin and excitons can be achieved by engineering between materials with magnetic and quantum dots with semiconducting properties. The most approach to achieve this is by designing core-shell nanoparticles at the nanoscale, where surface-to-volume ratios allow for unprecedented manipulation of the spin-excitonic coupli to synthesize highly controlled, homogeneous bi-phasic core-shell nanoparticles with tailo that unlock novel synergy within a single, integrated architecture. Our ultimate ambition the interface-driven coupling mechanisms, achieving full control over the properties of ma dot core-shell nanoparticles accompanied by in depth characterization using cutting-edge i situ techniques, such as polarized neutron scattering experiments, revealing critical insi arrangements, chemical distribution, interfacial strain, and magnetic order at the interfa ambitious objectives are threefold: (1) to elucidate the fundamental mechanisms governing coupling at the microscopic level, (2) to achieve precise control over the synthesis of th shell interface, and (3) to leverage this knowledge for the targeted enhancement of couple across multiple applications. By advancing the synthesis and understanding of multiphase c nanomaterials, this project has the potential to deliver breakthrough innovations in next- spintronics, quantum information systems, energy-efficient optoelectronics, and next-gener technologies.Sustainable Development Go Meet the Project If you had to explain your project to someone outside your field, how would you describe i sentences? My project, SPINEX, explores a radical idea: using a flash of light to switch the magnetic material – like a switch, but governed by quantum physics. To do this, I study how exciton packets born when light is absorbed) interact with the magnetic spin of electrons – an int "compass needle" inside each particle. Ultimately, this research will lay the foundation f of light-responsive magnetic nanomaterials, driving innovation across quantum information efficient optoelectronics, and next-generation biomedical technologies. What fascinates you most about the topic of your research project? Imagine a world where the internet cannot be hacked, computers run on a fraction of today' can deliver medicine directly to diseased cells without harming healthy ones, and solar pa nearly every photon that touches them. That world is not science fiction – it is the horiz is moving toward. All of this becomes possible by understanding spin–exciton coupling insi magnetic quantum dots, a tiny, engineered nanostructures where light and magnetism meet at scale. At this scale, the ordinary rules of physics give way to quantum behaviour, and tha where the most exciting discoveries live. This research lays the foundation to computers that are faster and far more energy-efficie would use spins and light instead of just electrical currents. It will form the groundwork communication systems – completely secure networks, where any attempt to intercept the com changes the quantum state of the system and reveals the intruder. These quantum dots can b medicine. They will help doctors deliver drugs directly to diseased cells, reducing side e controlling light and magnetism at this tiny scale, it is possible to make better solar pa based devices, turning more sunlight into usable energy and improving everyday technologie This project is not only about fundamental physics, it is about taking a decisive step tow smarter, and more sustainable future. That is what captured my imagination and keeps me at day. How does your research contribute specifically to achieving the UN Sustainable Development SPINEX contributes directly to three United Nations Sustainable Development Goals by trans scale discoveries into real-world technologies. On the energy front (SDG 7), understanding spin–exciton coupling enables the design of ene devices and next-generation light-harvesting systems. Replacing conventional silicon elect based (spintronic) architectures could dramatically cut the energy consumed by computers a reducing carbon emissions at a global scale and accelerating the transition to green energ For innovation and infrastructure (SDG 9), the ability to control magnetism with light unl new device families: opto-spintronic sensors, neuromorphic computing chips that mimic the quantum information processors. As global data consumption continues to surge, spintronic to be faster, smaller, more reliable, and vastly more energy-efficient than anything built electronics. Finally, for quality education (SDG 4), SPINEX places cutting-edge interdisciplinary scien condensed matter physics, photonics, materials science, and quantum information at the hea next generation's training. This research grows the global community of scientists equippe sustainable challenges, contributing knowledge that will underpin tomorrow's green and qua
