Publications
Every result, out in the open.
We write our predictions down before each calculation runs, then publish the results, the data and the code so anyone can check them. Here is everything we have released so far, and where to find it.

Talks
APS Global Physics Summit 2027Atlanta and online, April 11–16, 2027. The American Physical Society’s Global Physics Summit is the world’s largest physics research conference, bringing together more than 14,000 physicists, engineers, students, national-laboratory scientists and industry leaders at the Georgia World Congress Center in Atlanta and online.
Our talk“Ambient-pressure Li₈Au: nearly degenerate fcc orderings near the Li–Au convex hull,” presented by James Epperson. A contributed oral talk in the Electrochemical Energy Storage and Conversion program, delivered virtually and available on demand to Summit registrants. Abstract submitted October 2026; acceptance pending.
What it coversThe J phase, a lithium-rich gold alloy found by calculation, and why several nearly equal arrangements of its atoms sit close to the most stable lithium–gold mixes — close enough to matter for lithium-metal batteries.
