Research and career
Vergniory worked as a research fellow at the Ikerbasque and the Donostia International Physics Center. [7] She studied novel materials and computational strategies to realise new condensed matter systems. [8]
Verginory became interested in the design of new topological materials with optimised functional properties. [9] [10] Topological materials are insulators in the bulk but conductive on their surfaces. [11] The conducting channels that facilitate current flow are robust and independent of size.
Vergniory studied the Inorganic Crystal Structure Database to identify topologically nontrivial materials. [12] She designed a computational effort to simulate real materials and determine whether or not they showed topological properties. [13] This included complex theoretical analysis that could classify topological phases, and information from materials scientists on whether materials were suitable or not. [14] Vergniory uses her supercomputers to perform her calculations ab initio. [6] In an interview with Physics World , Verginory said that she had been surprised by how many materials she identified with topological properties. [14] As an output of this work, the high-order topological insulator Bi4Br4 was synthesised and studied experimentally. She showed that if it was possible to identify the symmetry of the crystalline symmetry of a material, she could easily anticipate the behaviour of the charge. [14] She has since started investigating organic materials. [14] She believes that topological crystals with a chiral structure will display several exotic physical phenomena. [15]
