Unsupervised learning of topological phase diagram using topological data analysis
Sungjoon Park, Yoonseok Hwang, Bohm-Jung Yang
Topology and machine learning are two actively researched topics not only in condensed matter physics, but also in data science. Here, we propose the use of topological data analys…
Topological acoustic triple point
Sungjoon Park, Yoonseok Hwang, Hong Chul Choi +1
Acoustic phonon in a crystalline solid is a well-known and ubiquitous example of elementary excitation with a triple degeneracy in the band structure. Because of the Nambu-Goldston…
DC spin generation by junctions with AC driven spin-orbit interaction
M. Jonson, R. I. Shekhter, O. Entin-Wohlman +3
An unbiased one-dimensional weak link between two terminals, subjected to the Rashba spin-orbit interaction caused by an AC electric field which rotates periodically in the plane p…
Suppression of magnetic ordering in XXZ-type antiferromagnetic monolayer NiPS3
Kangwon Kim, Soo Yeon Lim, Jae-Ung Lee +7
How a certain ground state of complex physical systems emerges, especially in two-dimensional materials, is a fundamental question in condensed-matter physics. A particularly inter…
Influences of interfacial oxidization on surface magnetic energy, magnetic damping and spin-orbit-torques in Pt / ferromagnet / capping structures
DongJoon Lee, WonMin Jeong, DeokHyun Yun +6
We investigate the effect of capping layer (CAP) on the interfacial magnetic anisotropy energy density (K_S), magnetic damping (α), and spin-orbit torques (SOTs) in heavy-metal (Pt…
Valley Hall Transport of Photon-Dressed Quasiparticles in 2D Dirac Semiconductors
V. M. Kovalev, Wang-Kong Tse, M. V. Fistul +1
We present a theory of the photovoltaic valley-dependent Hall effect in a two-dimensional Dirac semiconductor subject to an intense near-resonant electromagnetic field. Our theory…
