Topological metals induced by Zeeman effect

2019 · arXiv (Cornell University)

In the present paper, we propose a new way to classify centrosymmetric metals by studying the Zeeman effect caused by an external magnetic field described by the momentum dependent g-factor tensor on the Fermi surfaces. …

Iterated Agent for Symbolic Regression

2025 · arXiv (Cornell University)

Symbolic regression (SR), the automated discovery of mathematical expressions from data, is a cornerstone of scientific inquiry. However, it is often hindered by the combinatorial explosion of the search space and a tendency to overfit. …
