Cross-sublattice Spin Pumping and Magnon Level Attraction in van der Waals Antiferromagnets
Roberto E. Troncoso, Mike A. Lund, Arne Brataas +1
We theoretically study spin pumping from a layered van der Waals antiferromagnet in its canted ground state into an adjacent normal metal. We find that the resulting dc spin pumpin…
Motion-induced inertial effects and topological phase transitions in skyrmion transport
Allison W. Teixeira, Sebastián Castillo-Sepúlveda, Leandro G. Rizzi +5
In this work, the current-induced inertial effects on skyrmions hosted in ferromagnetic systems are studied. {When the dynamics is considered beyond the particle-like description,…
Fingerprints of Universal Spin-Stiffness Jump in Two-Dimensional Ferromagnets
Roberto E. Troncoso, Arne Brataas, Asle Sudbø
Motivated by recent progress on synthesizing two-dimensional magnetic van der Waals systems, we propose a setup for detecting the topological Berezinskii-Kosterlitz-Thouless (BKT)…
Bosonic Bott Index and Disorder-Induced Topological Transitions of Magnons
X. S. Wang, Arne Brataas, Roberto E. Troncoso
We investigate the role of disorder on the various topological magnonic phases present in deformed honeycomb ferromagnets. To this end, we introduce a bosonic Bott index to charact…
Magnon valley Hall effect in CrI3-based vdW heterostructures
R. Hidalgo-Sacoto, R. I. Gonzalez, E. E. Vogel +5
Magnonic excitations in the two-dimensional (2D) van der Waals (vdW) ferromagnet CrI3 are studied. We find that bulk magnons exhibit a non-trivial topological band structure withou…
