About the Project
This PhD project aims to advance our knowledge of these states by using magnetic ﬁeld and pressure to enable a continuous, clean and reversible tuning of quantum interactions, thereby shedding light on the building blocks of quantum materials. The project takes as its starting point recent theoretical and experimental discoveries in the area. In particular, we will focus on a selected series of materials that are on the verge of a phase instability. For example, recently my research team has shown that using molecular-building blocks it is possible to construct near-ideal examples of one and twodimensional magnets that exhibit some deeply quantum eﬀects in high ﬁelds (see Fig.1) [1,3]. We also investigate exotic metallic systems, such as CeOs4Sb12 whose ground state has a most unusual, highly pressure dependent phase diagram governed by proximity to a topological semimetal state and a quantum critical point driven by applied magnetic ﬁeld.
Taking these systems and others, we will use ultra-high ﬁelds and applied pressure to push them through the critical region where the state of matter changes and the inherently quantum eﬀects dominate. Electronic, magnetic and structural properties will be measured as the tipping point is breached and the resulting data compared with predictions of theoretical models. We hope that the results will provide answers to questions of deep concern to modern physics, such how quantum ﬂuctuations, topology and disorder can be used to create states of matter with fascinating and functional properties.
Applications are accepted at any time, but it is likely that interviews will be from January 2020 onwards.
