Enhanced pair-density-wave vertices in a bilayer Hubbard model at half-filling
Fangze Liu, Xu-Xin Huang, Edwin W. Huang +2
Motivated by the pair-density-wave (PDW) state found in the one-dimensional Kondo-Heisenberg chain, we report on a determinant quantum Monte Carlo DQMC study of pair-fields for a t…

The emergence of antiferromagnetic correlations and Kondo-like features in a two-band model for infinite-layer nickelates
Fangze Liu, Cheng Peng, Edwin W. Huang +3
We report a determinant quantum Monte Carlo study of a two-band model, inspired by infinite-layer nickelates, focusing on the influence of interlayer hybridization between $3d_{x^2…

Self-Supervised Generative Models for Crystal Structures
Fangze Liu, Zhantao Chen, Tianyi Liu +4
Drawing inspiration from the achievements of natural language processing, we adopt self-supervised learning and utilize an equivariant graph neural network to develop a unified pla…
