Electric field driven octahedral rotation in perovskite
Wonshik Kyung, Choong H. Kim, Yeong Kwan Kim +9
Rotation of MO6 (M = transition metal) octahedra is a key determinant of the physical properties of perovskite materials. Therefore, tuning physical properties, one of the most imp…
InterPhon: Ab initio Interface Phonon Calculations within a 3D Electronic Structure Framework
In Won Yeu, Gyuseung Han, Kun Hee Ye +2
This work provides the community with an easily executable open-source Python package designed to automize the evaluation of Interfacial Phonons (InterPhon). Its strategy of arbitr…
BiSe thin films heteroepitaxially grown on -RuCl
Joon Young Park, Janghyun Jo, Jennifer A. Sears +4
Combining various two-dimensional materials into novel van der Waals (vdW) heterostructures has been shown to lead to new emergent quantum systems. A novel heterostructure composed…
Spin-orbit coupling effects on spin-phonon coupling in Cd2Os2O7
Taehun Kim, Choong H. Kim, Jaehong Jeong +8
Spin-orbit coupling (SOC) is essential in understanding the properties of 5d transition metal compounds, whose SOC value is large and almost comparable to other key parameters. Ove…
Pressure-induced huge increase of Curie temperature of the van der Waals ferromagnet VI3
J. Valenta, M. Kratochvílová, M. Míšek +12
Evolution of magnetism in single crystals of the van der Waals compound VI3 in external pressure up to 7.3 GPa studied by measuring magnetization and ac magnetic susceptibility is…
Gaussian time-dependent variational principle for the finite-temperature anharmonic lattice dynamics
Jae-Mo Lihm, Cheol-Hwan Park
The anharmonic lattice is a representative example of an interacting bosonic many-body system. The self-consistent harmonic approximation has proven versatile for the study of the…
