Graph Coloring with Physics-Inspired Graph Neural Networks
Martin J. A. Schuetz, J. Kyle Brubaker, Zhihuai Zhu +1
We show how graph neural networks can be used to solve the canonical graph coloring problem. We frame graph coloring as a multi-class node classification problem and utilize an uns…

Probing Image Potential States on Topological Semimetal Antimony Surface
Jian-Feng Ge, Haimei Zhang, Yang He +4
A point charge near the surface of a topological insulator (TI) with broken time-reversal symmetry is predicted to generate an image magnetic charge in addition to an image electri…
