Overview
The Department of Physics at Lancaster University invites applications for a Post-Doctoral Research Associate (or Senior Research Associate) to work in the field of ultrafast switching of magnetism. The post is funded by Green Future Fellowship project: Terahertz magnetic recording for green data storage technology.
We're looking for people who have a passion for science, with ambition to apply their own ideas, perspectives, and their personal skillset to the discovery new spin switching scenarios and development of ultrafast magnetic recording technology. We'd like you to be part of the team that helps drive translation of energy efficient data storage to commercial success.
The advent of artificial intelligence and the proliferation of cloud-based technologies call for denser, faster and more energy efficient data processing and storage. However, the heat produced by modern data centres has already become a serious limitation to further increase their performance. At present, the data industry lacks a solution for this problem, which in future may contribute greatly to the global warming and energy crisis. This project aims to pave a way towards a memory-device characterized by very low energy consumption and switching times of one trillionth of a second. Very short pulses of electro-magnetic radiation at terahertz frequency (i.e. thousand times faster than that in current data communication and processing standards) are among the shortest stimuli available. These pulses are made from light particles, photons, with their energies naturally matching those of elementary quantum magnets, "spins", which are used to store information in the magnetic memory. Hence, such terahertz photons can selectively excite spins on their own energy scale without releasing any significant heating into the surrounding medium. Furthermore, the terahertz excitation of the spins is expected to be strong enough to induce switching of the spins' orientations, representing an elementary act of writing a bit of information within a magnetic data storage device.
The position offers access to state-of-the art ultrafast laser facilities and challenging research project at the interface of photonics and magnetism. You will contribute to solving the existential challenge to the humankind: excessive energy consumption by data-intensive technologies such as Artificial Intelligence, Internet of Things and cloud computing.
The post is available immediately and is offered for 24 months at the first instance. The further extension of the post is possible subject to performance.
