Towards Quantum States of Matter via Chemistry under Extreme Conditions

Objective

Quantum materials hold the promise to spark the next technological revolution; the realization of quantum computers, high-speed electronic devices, or cheap energy delivered over superconducting wires could transform our society. However, the experimental realisation of such devices is slow to develop due to a lack of understanding of crucial underlying quantum phenomena. Magnetic systems with low dimensionality could provide one of the most important avenues for the realisation of exotic quantum states of matter. Yet the exploration of the properties and applications of quantum materials relies on advances in synthesis techniques. With the aim of expanding the frontiers of quantum materials, this project aims to explore low dimensional quantum systems under extreme conditions of temperature and pressure. Motivated by finding quantum states of matter, the synthesis of new magnetic phases with a one-dimensional and two-dimensional arrangement of spins is targeted. Firstly, the realization of 1D quantum magnetism in quasi-one-dimensional La3MoO7 by chemical and physical means will be explored. Secondly, the realization of spin ½ decorated anisotropic Shastry-Sutherland lattice in the quasi-two-dimensional SrCu2(BO3)2 system by chemical doping (on both A- and B-site) will be investigated. A plethora of synthetic techniques including high-pressure synthesis in the GPa range will be employed to obtain the targeted phases. The physical properties of the synthesised materials will be investigated through a variety of cutting-edge characterisation techniques such as X-ray and neutron scattering, electron paramagnetic resonance, nuclear magnetic and muon spin resonance which will reveal important information on the nature of the magnetic interactions and dimensionality. The results of this project may provide new systems that exhibit quantum phenomena and thus help to expand the frontiers of quantum materials.
