Strong charge and spin fluctuations in La $_{2}$ O $_{3}$ Fe $_{2}$ Se $_{2}$

Guangxi Jin, Yilin Wang, Xi Dai +2

The electronic structure and magnetic properties of the strongly correlated material La $_{2}$ O $_{3}$ Fe $_{2}$ Se $_{2}$ are studied by using both the density function theory plus $U$ (DFT+ $U$ …

The origin of hyperferroelectricity in Li $B$ O $_{3}$ ( $B$ =V, Nb, Ta, Os)

Pengfei Li, Xinguo Ren, Guang-Can Guo +1

The electronic and structural properties of Li $B$ O $_{3}$ ( $B$ =V, Nb, Ta, Os) are investigated via first-principles methods. We show that Li $B$ O $_{3}$ belong to the recently proposed hy…

Large-scale ab initio simulations based on systematically improvable atomic basis

Pengfei Li, Xiaohui Liu, Mohan Chen +5

We present a first-principles computer code package (ABACUS) that is based on density functional theory and numerical atomic basis sets. Theoretical foundations and numerical techn…
