Data-driven design of high-temperature superconductivity among ternary hydrides under pressure
Bowen Jiang, Xiaoshan Luo, Toshiaki Iitaka +6
Recently, ternary clathrate hydrides are promising candidates for high-temperature superconductor. However, it is a formidable challenge to effectively hunt high-temperature superc…
Giant electro-optic effect in chiral topological semimetal RhSi
Zhi Li, Yuewen Gao, Yu Gu +3
We studied the linear electro-optic effect of chiral topological semimetal RhSi which is characterized by high-fold chiral fermions separated in energy space. We identify that the…
Detection of quantum geometric tensor by nonlinear optical response
Zhi Li, Takami Tohyama, Toshiaki Iitaka +2
Quantum geometric tensor (QGT), including a symmetric real part defined as quantum metric and an antisymmetric part defined as Berry curvature, is essential for understanding many…
Random Phase Product Sate for Canonical Ensemble
Toshiaki Iitaka
Method of random phase product state (RPPS) is proposed to calculate canonical ensemble average of quantum systems described with matrix product states and also with tensor network…
Nonlinear optical response from quantum kinetic equation
Zhi Li, Takami Tohyama, Toshiaki Iitaka +2
Motivated by the nonlinear Hall effect observed in topological semimetals, we studied the photocurrent by the quantum kinetic equation. We recovered the shift current and injection…
The impact of Hubbard- and van der Waals-corrections on the DFT calculation of epsilon-zeta transition pressure in solid oxygen
Le The Anh, Masahiro Wada, Hiroshi Fukui +1
The aim of this study is to clarify the physics which governs the transition from epsilon phase to zeta phase of solid oxygen observed experimentally at 96 GPa using density functi…
