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.

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: 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.
