Symmetry and localization properties of defect modes in magnonic superlattices
Rodolfo A. Gallardo, Tobias Schneider, Alejandro Roldán-Molina +5
Symmetry and localization properties of defect modes of a one-dimensional bi-component magnonic superlattice are theoretically studied. The magnonic superlattice can be seen as a p…
Spin-wave amplification and lasing driven by inhomogeneous spin transfer torques
R. J. Doornenbal, A. Roldán-Molina, A. S. Nunez +1
We show that an inhomogeneity in the spin-transfer torques in a metallic ferromagnet under suitable conditions strongly amplifies incoming spin waves. Moreover, at nonzero temperat…
Emission and Propagation of Multi-Dimensional Spin Waves with nanoscale wavelengths in Anisotropic Spin Textures
V. Sluka, T. Schneider, R. A. Gallardo +15
Spin waves offer intriguing novel perspectives for computing and signal processing, since their damping can be lower than the Ohmic losses in conventional CMOS circuits. For contro…
Flat Bands, Indirect Gaps, and Unconventional Spin-Wave Behavior Induced by a Periodic Dzyaloshinskii-Moriya Interaction
R. A. Gallardo, D. Cortés-Ortuño, T. Schneider +7
Periodically patterned metamaterials are known for exhibiting wave properties similar to the ones observed in electronic band structures in crystal lattices. In particular, periodi…
An Efficient, Second Order Accurate, Universal Generalized Riemann Problem Solver Based on the HLLI Riemann Solver
Dinshaw S. Balsara, Jiequan Li, Gino I. Montecinos
The Riemann problem, and the associated generalized Riemann problem, are increasingly seen as the important building blocks for modern higher order Godunov-type schemes. In the pas…
