Dr Matthew Coak

Background

I am a Postdoctoral Research Fellow specialising in high pressure techniques, working with Dr Paul Goddard to use pressure, magnetic fields and low temperatures to tune and study low-dimensional magnetic materials and superconductors.

I completed my undergraduate degree in physics at the University of Oxford, with my masters thesis on the development of proximity-detector-oscillators for use in pulsed magnetic fields. Following this I moved on to a PhD at the University of Cambridge under Dr Siddharth Saxena, graduating in 2017. My specialisation was in the use of high pressure to tune quantum criticality in ferroelectric systems and Mott transitions in 2D insulating antiferromagnets.

My first postdoctoral position was in the Emergent Phenomena Group of the IBS Centre for Correlated Electron Systems at Seoul National University, under Prof Je-Geun Park. Here I headed the van-der-Waals materials team and continued my investigation into Mott transitions and the tuning of low-dimensional magnetism with pressure, including synchrotron and neutron scattering studies. I then joined the Superconductivity and Magnetism group at Warwick in March 2019.

Research Interests

My current work focuses on the tuning of low-dimensional quantum magnet systems and materials which exhibit unconventional superconductivity through hydrostatic pressure, low temperatures, and ultra-high magnetic fields. The use of metal-organic framework, or coordination-polymer, crystalline materials leads to sufficiently low magnetic exchange energies to address the full magnetic phase diagram with achievable fields, and a rich variety of pressure effects on the organic ligands and exchange pathways linking magnetic sites.
