Topological waveguide based on metamaterials of magnetic solitons
Gyungchoon Go, Ik-Sun Hong, Seo-Won Lee +2
We theoretically investigate coupled gyration modes of magnetic solitons whose distances to the nearest neighbors are staggered. In a one-dimensional bipartite lattice, analogous t…
Controllable pn junctions in threedimensional Dirac semimetal CdAs nanowires
Janice Ruth Bayogan, Kidong Park, Zhuo Bin Siu +11
We demonstrate a controllable pn junction in a threedimensional Dirac semimetal (DSM) CdAs nanowire with two recessed bottom gates. The device exhibits four different…
SU(3) Topology of Magnon-Phonon Hybridization in 2D Antiferromagnets
Shu Zhang, Gyungchoon Go, Kyung-Jin Lee +1
Magnon-phonon hybrid excitations are studied theoretically in a two-dimensional antiferromagnet with an easy axis normal to the plane. We show that two magnon bands and one phonon…
Magnetic Skyrmion Field-Effect Transistors
Ik-Sun Hong, Kyung-Jin Lee
Magnetic skyrmions are of considerable interest for low-power memory and logic devices because of high speed at low current and high stability due to topological protection. We pro…
