Sparse modeling study of extracting charmonium spectral functions from lattice QCD at finite temperature
Junichi Takahashi, Hiroshi Ohno, Akio Tomiya
We present charmonium spectral functions extracted from Euclidean-time correlation functions using sparse modeling (SpM). SpM solves inverse problems by considering only the sparsi…

CASK: A Gauge Covariant Transformer for Lattice Gauge Theory
Yuki Nagai, Hiroshi Ohno, Akio Tomiya
We propose a Transformer neural network architecture specifically designed for lattice QCD, focusing on preserving the fundamental symmetries required in lattice gauge theory. The…
