Importance of effective Coulomb interactions for in cuprates
Jakša Vučičević, Upendra Kumar, Chia-Nan Yeh +2
Cuprate superconductors exhibit the highest observed superconducting at atmospheric pressure. However, the magnitude of varies significantly between different cuprates.…

Electronic correlations and dynamical screening with ab initio quantum embedding
Chia-Nan Yeh, Francesco Petocchi, Alexander Hampel +4
First-principles descriptions of correlated quantum materials require a simultaneous treatment of strong local many-body effects and nonlocal dynamical screening. We present an eff…

Interpolative separable density fitting on adaptive real space grids
Hai Zhu, Chia-Nan Yeh, Miguel A. Morales +3
We generalize the interpolative separable density fitting (ISDF) method, used for compressing the four-index electron repulsion integral (ERI) tensor, to incorporate adaptive real…
