Electron-phonon physics at the exascale: A hybrid MPI-GPU-OpenMP framework for scalable Wannier interpolation

Tae Yun Kim, Zhe Liu, Sabyasachi Tiwari +2

We demonstrate a highly efficient GPU implementation of the Wannier interpolation of electron-phonon matrix elements in the EPW code. Building on a systematic analysis of the compu…

First-principles study of bulk stacking, $J_{eff}$ picture, magnetic Hamiltonian, $g$ factors, and structural distortions of $I^\pm$ -RuCl $_{3}$

Seung-Ju Hong, Tae Yun Kim, Cheol-Hwan Park

$I^\pm$ -RuCl $_{3}$ is a candidate Kitaev material that exhibits zigzag antiferromagnetic ordering below 7 K. One contentious issue regarding this material is its bulk structure in the l…
