The energy consumption associated with information processing and storage is rapidly becoming unsustainable. The manipulation of magnetism and other collective quantum phenomena in solids using ultrashort pulses of light is a promising route towards implementing non-volatile and low-dissipation storage of information. In this project we address these questions in a class of materials recently discovered. We aim at demonstrating low-dissipative magnetic switching obtained by ultrafast control of the crystal lattice. In order to reach this goal, we develop bespoke materials engineered at the atomic scale.
For this project we have designed a new class of magnetic materials controlled at the atomic scale, where magnetism is strongly coupled to the exact atomic configuration of the crystal lattice. Such an unstable landscape is produced by design, in order to create a magnetic system susceptible to switching with ultralow dissipation.
This project brings together for the first time, material-by-design approaches with ultrafast light control of solids. By the end of the project we expect to demonstrate a new route for ultrafast control of quantum phases of matter.
