DOI: 10.1038/s41567-018-0058-3
Abstract: Magnetohydrodynamic Alfvén waves1 have been a focus of laboratory plasma physics2 and astrophysics3 for over half a century. Their unique nature makes them ideal energy transporters, and while the solar atmosphere provides preferential conditions for… read more here.

Abstract: Shear Alfvén wave parametric decay instability (PDI) provides a potential path toward significant wave dissipation and plasma heating. However, fundamental questions regarding how PDI is excited in a realistic three-dimensional (3D) open system and how… read more here.

DOI: 10.1073/pnas.2220927120
Abstract: We report analytical and numerical investigations of subion-scale turbulence in low-beta plasmas using a rigorous reduced kinetic model. We show that efficient electron heating occurs and is primarily due to Landau damping of kinetic Alfvén… read more here.

Abstract: In this work, most of the weakly coherent mode (WCM) characteristics and the level of transport coefficients observed in I-mode pedestal plasmas of C-Mod are reproduced theoretically. The dispersion relation of drift-Alfvén wave (DAW) is… read more here.

DOI: 10.1093/mnras/staf1385
Abstract: Parametric instability of Alfvén wave packets with monochromatic carrier wave in low-β plasma is studied using one-dimensional magnetohydrodynamic simulations. The results show spatial growth of incoming perturbations as they propagate through the mother wave. For… read more here.

DOI: 10.1093/mnrasl/sly106
Abstract: Alfv\'en waves are primal and pervasive in space plasmas and significantly contributes to microscale fluctuations in the solar wind and some heliospheric processes. Here, we demonstrate the first observable distinct feature of Alfv\'en wave while… read more here.

DOI: 10.1103/physrevlett.128.075101
Abstract: Magnetic energy around astrophysical compact objects can strongly dominate over plasma rest mass. Emission observed from these systems may be fed by dissipation of Alfvén wave turbulence, which cascades to small damping scales, energizing the… read more here.

DOI: 10.1126/sciadv.aav8411
Abstract: Global Alfvén wave power above the auroral zone increases fourfold during geomagnetic storms. Geomagnetic storms are large space weather events with potentially tremendous societal implications. During these storms, the transfer of energy from the solar… read more here.
