# Maia Vergniory

Maia Garcia Vergniory is a Spanish computational physicist who is a group leader at the Max Planck Institute for Chemical Physics of Solids. Her work in topological quantum chemistry investigates the phases of topological materials. She was elected Fellow of the American Physical Society in 2022.

## Early life and education

Vergniory was born in Getxo. She was a doctoral researcher at the University of the Basque Country. Her research considered many-body effects on the interactions between excited electronic states and the mobile ions on surfaces. She started working on topological materials in 2012.

## Research and career

Vergniory worked as a research fellow at the Ikerbasque and the Donostia International Physics Center. She studied novel materials and computational strategies to realise new condensed matter systems.

Verginory became interested in the design of new topological materials with optimised functional properties. Topological materials are insulators in the bulk but conductive on their surfaces. 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. She designed a computational effort to simulate real materials and determine whether or not they showed topological properties. This included complex theoretical analysis that could classify topological phases, and information from materials scientists on whether materials were suitable or not. Vergniory uses her supercomputers to perform her calculations ab initio. In an interview with Physics World, Verginory said that she had been surprised by how many materials she identified with topological properties. As an output of this work, the high-order topological insulator $Bi_4Br_4$ 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. She has since started investigating organic materials. She believes that topological crystals with a chiral structure will display several exotic physical phenomena.
