Equilibrium current vortices in rare-earth-doped simple metals
Adam B. Cahaya, Alejandro O. Leon, Mojtaba Rahimi Aliabad +1
Dilute alloys of rare earths have played a vital role in understanding magnetic phenomena. Here, we model the ground state of dilute 4f rare-earth impurities in light metals. When…
Layer effects on the magnetic textures in magnets with local inversion asymmetry
Etienne van Walsem, Rembert A. Duine, Marcos H. D. Guimarães
Magnets with broken local inversion symmetries are interesting candidates for chiral magnetic textures such as skyrmions and spin spirals. The property of these magnets is that eac…
Non-Hermitian coherent coupling of nanomagnets by exchange spin waves
Hanchen Wang, Jilei Chen, Tao Yu +16
Non-Hermitian physics has recently attracted much attention in optics and photonics. Less explored is non-Hermitian magnonics that provides opportunities to take advantage of the i…

The control of magnetic materials and devices by voltages without electric currents holds the promise of power-saving nano-scale devices. Here we study the temperature-dependent vo…
Plasmon-assisted two-photon absorption in a semiconductor quantum dot -- metallic nanoshell composite
Bintoro S. Nugroho, Alexander A. Iskandar, Victor A. Malyshev +1
Tho-photon absorption holds potential for many practical applications. We theoretically investigate the onset of this phenomenon in a semiconductor quantum dot -- metallic nanoshel…
Detecting chirality in two-terminal electronic devices
Xu Yang, Caspar H. van der Wal, Bart J. van Wees
Central to spintronics is the interconversion between electronic charge and spin currents, and this can arise from the chirality-induced spin selectivity (CISS) effect. CISS is oft…

The proximity of a transition metal dichalcogenide (TMD) to graphene imprints a rich spin texture in graphene and complements its high quality charge/spin transport by inducing spi…
Nonlocal Spin Transport as a Probe of Viscous Magnon Fluids
Camilo Ulloa, A. Tomadin, J. Shan +3
Magnons in ferromagnets behave as a viscous fluid over a length scale, the momentum-relaxation length, below which momentum-conserving scattering processes dominate. We show theore…

The intrinsic non-linearities of the spin dynamics in condensed matter systems give rise to a rich phenomenology that can be strongly affected by topology. Here we study formation…
