@article{3871, author = {Ian Ochs and Nathaniel Fisch}, title = {Momentum-Exchange Current Drive by Electrostatic Waves in an Unmagnetized Collisionless Plasma}, abstract = {For a planar electrostatic wave interacting with a single species in a collisionless plasma, momentum conservation implies current conservation. However, when multiple species interact with the wave, they can exchange momentum, leading to current drive. A simple, general formula for this driven current is derived. As examples, we show how currents can be driven for Langmuir waves in electron-positron-ion plasmas, and for ion-acoustic waves in electron-ion plasmas.}, year = {2020}, journal = {Physics of Plasmas}, volume = {27}, number = {6}, pages = {062109}, month = {jun}, publisher = {AIP Publishing LLC}, issn = {1070-664X}, doi = {10.1063/5.0011516}, }
