[4] Such materials are insulators in the bulk but have protected metallic surfaces, on which electrons cannot backscatter and outstanding transport mobilities are observed.
[4] In an effort to realise high performance next-generation devices, Coldea makes use of nanoscale tools to study topological insulators in low dimensional nanostructures.
[8] Superconductivity is a surprising observation in iron, as its strong ferromagnetism was expected to destroy any coherent electronic state.
These states break rotational symmetry, which gives rise to a distorted Fermi surfaces and anisotropic transport properties.
[7] She is interested in the use of high magnetic fields (up to 21 T) and cryogenic temperatures (down to 50 mK) to identify and study novel phases within quantum materials.
[11] She was named a Fellow of the American Physical Society in 2023 "for pioneering studies of the electronic structure and the nematic and superconducting orders of iron-based superconductors, using quantum oscillations, photoemission, and other techniques".
