Self-Consistent Coulomb Interactions from Constrained Dynamical Mean-Field Theory
Antik Sihi, Subhasish Mandal, Kristjan Haule
We develop a self-consistent first-principles framework for determining the screened Coulomb interaction strength (U) based on constrained dynamical mean-field theory (cDMFT). Unli…

Accelerated prediction of dielectric functions in solar cell materials with graph neural networks
Caden Ginter, Kamal Choudhary, Subhasish Mandal
We present an atomistic line graph neural network (ALIGNN) model for predicting dielectric functions directly from crystal structures. Trained on 7000 dielectric functions fr…

High-throughput Search for Metallic Altermagnets by Embedded Dynamical Mean Field Theory
Xuhao Wan, Subhasish Mandal, Yuzheng Guo +1
Altermagnets (AM) are a novel class of magnetic materials with zero net magnetization but broken time-reversal symmetry and spin-split bands exceeding the spin-orbit coupling scale…
