Using {\it ab initio} approaches for extended Hubbard interactions coupled to phonons, we reveal that the intersite Coulomb interaction plays important roles in determining various distinctive phases of the paradigmatic charge ordered materials of Ba

The phonon angular momentum (PAM) may exhibit exotic temperature dependence as it is sensitive to the phonon lifetime. Constant phonon-lifetime approximation fails to depict such behavior. Here, we study the PAM of AlN, GaN, and graphene-like boron n

Summary Poor solubility of π-conjugated two-dimensional polymers (C2Ps) has been a significant roadblock in incorporating these emergent materials into electronic devices by simple solution processing. Here, we report a rational design of triphenyle

We study the lattice dynamics of antiferromagnetic transition-metal oxides by using self-consistent Hubbard functionals. We calculate the ground states of the oxides with the on-site and intersite Hubbard interactions determined self-consistently wit

We study the lattice dynamics of group IV semiconductors using the fully ab initio extended Hubbard functional. The on-site and intersite Hubbard interactions are determined self-consistently with recently developed pseudohybrid functionals and inclu

Polar metal is a material that hosts both polar distortion and metallicity. Such a material is expected to show exotic magneto-electric phenomena if it superconducts. Here, we theoretically explore ferroelectric and superconducting properties in a se

Ge-Sb-Te-based phase-change materials (PCMs) exhibit contrasting electrical and optical properties upon change in atomic structures, which contain the octahedral p -orbital bonding and also substantial disordered vacancies. While extensive studies ha

Understanding the role of partially occupied sites in Li-based superionic conductors is key to improving performance of solid-state electrolyte materials. We study the optimized structure of crystalline β-Li3PS4 and the Li-ion diffusion using first-
