New Physics with Strongly Correlated and Spin-Orbit Coupled Electrons
Grant number: FT180100211 | Funding period: 2018 - 2022
This project aims to identify new physics in quantum magnets and emergent phenomena in solids where the electrons are strongly coupled and intertwined in a complex manner. As a consequence, quantum effects are dramatically enhanced and, in certain situations, force the electrons to split into different exotic particles. This project expects to identify suitable physical systems, candidate materials and appropriate conditions required for the experimental observation of this phenomena with neutron scattering methods. The advanced materials and exotic particles identified in this project will inform the development of next generation technologies, becoming the quantum bits in future quantum co..View full description
