Magnetoelastic coupling enabled tunability of magnon spin current generation in 2D antiferromagnets
Nasim Bazazzadeh, Mohammad Hamdi, Sungjoon Park +3
We theoretically investigate the magnetoelastic coupling (MEC) and its effect on magnon transport in two-dimensional antiferromagnets with a honeycomb lattice. MEC coeffcient along…
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…
Temperature selective thermometry with sub-microsecond time resolution using dressed-spin states in diamond
Jiwon Yun, Kiho Kim, Sungjoon Park +1
Versatile nanoscale sensors that are susceptible to changes in a variety of physical quantities often exhibit limited selectivity. This paper reports a novel scheme based on microw…
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…
