Topological Transport of Vorticity in Heisenberg Magnets
Ji Zou, Se Kwon Kim, Yaroslav Tserkovnyak
We study a robust topological transport carried by vortices in a thin film of an easy-plane ferromagnetic insulator between two metal contacts. A vortex, which is a nonlocal topolo…
Vanishing skyrmion Hall effect at the angular momentum compensation temperature of a ferrimagnet
Yuushou Hirata, Duck-Ho Kim, Se Kwon Kim +14
Charged particles exhibit the Hall effect in the presence of magnetic fields. Analogously, ferromagnetic skyrmions with non-zero topological charges and finite fictitious magnetic…
Tunable Magnonic Thermal Hall Effect in Skyrmion Crystal Phases of Ferrimagnets
Se Kwon Kim, Kouki Nakata, Daniel Loss +1
We theoretically study the thermal Hall effect by magnons in skyrmion crystal phases of ferrimagnets in the vicinity of the angular momentum compensation point (CP). To this end, w…
The COSINE-100 Data Acquisition System
100 Collaboration, G. Adhikari, P. Adhikari +44
COSINE-100 is a dark matter direct detection experiment designed to test the annual modulation signal observed by the DAMA/LIBRA experiment. COSINE-100 consists of 8 NaI(Tl) crysta…
Nonlocal Spin Transport Mediated by a Vortex Liquid in Superconductors
Se Kwon Kim, Roberto Myers, Yaroslav Tserkovnyak
Departing from the conventional view on superconducting vortices as a parasitic source of dissipation for charge transport, we propose to use mobile vortices as topologically-stabl…
Stabilization of the skyrmion crystal phase in thin-film antiferromagnets
Ricardo Zarzuela, Se Kwon Kim, Yaroslav Tserkovnyak
We investigate the formation and stability of the skyrmion crystal phase in antiferromagnetic thin films subjected to fieldlike torques such as, e.g., those induced by an electric…
