Representability-Aware Neural Networks for Reduced Density Matrices: Application to Fractional Chern Insulators
Justin B. Hart, Awwab A. Azam, Thomas Li +4
We develop a representability-aware and interpolable neural network (NN) framework for predicting two-particle reduced density matrices (2-RDMs). The NN incorporates a subset of re…

Wilson-Loop-Ideal Bands and General Idealization
Awwab A. Azam, Biao Lian, Shinsei Ryu +1
Quantum geometry is universally bounded from below by Wilson-loop windings. In this work, we define an isolated set of bands to be Wilson-loop-ideal, if their quantum metric satura…

Reduced Density Matrices Through Machine Learning
Awwab A. Azam, Lexu Zhao, Jiabin Yu
-particle reduced density matrices (-RDMs) play a central role in understanding correlated phases of matter, but their calculation is often computationally inefficient for st…
