Frontiers in research of emergent materials

Lead Research Organisation: University of Oxford
Department Name: Oxford Physics

Abstract

This proposal aims to facilitate effective interaction between a range of scientists including experimental and theoretical physicists, chemists and material scientists to identify the organizing principles responsible for the remarkable range of quantum phases observed in strongly correlated electron systems, to predict and explore new avenues for research and discover novel functional materials. Funding is sought for organizing workshops, facilitating exchange visits, setting up a visiting programme for international leading researchers and for seeding projects related to discovery of novel materials.

Planned Impact

While future scientific endeavor is difficult to predict in advance, the discovery of unexpected physics displayed by strongly correlated systems with markedly improved multifunctional properties compared with widely used semiconductors will one day have a dramatic effect on our lives. Emergent phenomena, in which the correlated behavior of many particles leads to collective new properties, are of great significance across a broad range of areas in science. However, the objective is to tailor a material (starting with its chemical composition, constituent phases) in order to obtain a desired set of properties suitable for a given application. Today technological advances are based on semiconductor physics due to their high degree of precise processing. However, if the same can be achieved for strongly correlated materials which have multifunctional and unique properties, such as superconductivity and magnetism. not found in semiconductors, would open up remarkable technological possibilities.

Description The aim of this proposal was to facilitate the effective interaction between a range of scientists including experimental and theoretical physicists, chemists and material scientists working on quantum phases observed in strongly correlated. This has been achieved by organizing an annual symposium dedicated to quantum materials (Quantum Symposium on Quantum Materials), visits of international leading researchers to enhanced our research, developing new quantum materials and establishing new research collaborations.
Exploitation Route Generate new collaborations, new directions, future funding (Oxford Quantum Materials Platform Grant and Oxford Centre for Applied Superconductivity), interaction with industry via the Oxford Centre for Applied Superconductivity, organization of the international conference Quantum Materials Symposium (2019) (https://qms.web.ox.ac.uk/home).

Description This funding has enhanced the interdisciplinary interactions between together physicists, chemists, materials scientists and theoreticians in and around Oxford in order to advance the science and promote direct collaboration between groups interested in novel quantum materials and phenomena. The Oxford Symposium on Quantum Materials has become an important annual interdisciplinary forum (~100 participants) and it has also brought to Oxford the international annual symposium, Quantum Materials Symposium 2019. These forums have provided the platform for new collaborations and interactions between among the participants as well as with policy makers, publishers and industry. . Beneficiaries: Academics, researchers and students (80 participants) and has resulted in new interactions and collaborations. Contribution Method: This meeting has provided the necessary ingredients towards collaborations in overlapping research areas with the aim to advance knowledge, train scientists and open up new avene of research by collaboration.
