Transport theory and spin-transfer physics in d-wave altermagnets
Ricardo Zarzuela, Rodrigo Jaeschke-Ubiergo, Olena Gomonay +2
We develop a mesoscale transport theory for the charge and spin degrees of freedom of itinerant carriers in a -wave altermagnet. Our effective Lagrangian description is built up…
Non-Abelian Gauge Theory for Magnons in Topologically Textured Frustrated Magnets
Ricardo Zarzuela, Se Kwon Kim
We develop an effective gauge theory for three-flavored magnons in frustrated magnets hosting topological textures with the aid of the quaternion representation of the SO(3) order…
Spin-transfer and Topological Hall Effects as Novel Probes for Magnetic Disclinations in Frustrated Magnets
Ricardo Zarzuela, Jairo Sinova
Magnetic frustrated systems have resurged in spintronics as optimal candidates for hosting three dimensional topological solitons, such as Shankar skyrmions and 4-vortices, and…
Josephson junction with a magnetic vortex
R. Zarzuela, E. M. Chudnovsky, J. Tejada
We have studied Josephson tunneling through a circularly polarized micron or submicron-size disk of a soft ferromagnetic material. Such a disk contains a vortex that exhibits rich…
