Story Highlights

In 2021, Arizona State Professor of Physics Antia Botana helped discover a new form of superconducting nickelate using computational methods.

Identifying and determining the characteristics of the superconducting material lets researchers explore similarities and differences among nickelates and between nickelates and cuprates — a promising class of promising copper-based materials.

Both families of materials appear to display ‘super-exchange,' where the material trades electrons in copper or nickel atoms through a pathway that contains oxygen, rather than directly. This, Botana says, may be one of the factors that governs superconductivity.

Botana uses the Stampede2 supercomputer at TACC as well as systems at Arizona State University to enable her quantum material studies.
