摘要：
当多种粒子与静电离子声波相互作用时，尽管场本身无动量，它们仍可交换动量。作用在电子上的合力可具有旋度，从而在磁流体力学时间尺度上产生具有旋度的补偿电场，由此生成磁场。令人惊讶的是，在某些天体物理环境中，该机制能以甚至高于传统Biermann电池的增长率来为磁场提供种子。
英文摘要：
When multiple species interact with an electrostatic ion acoustic wave, they can exchange momentum, despite the lack of momentum in the field itself. The resulting force on the electrons can have a curl, and thus give rise to compensating electric fields with curl on magnetohydrodynamic timescales. As a result, a magnetic field can be generated. Surprisingly, in some astrophysical settings, this mechanism can seed magnetic fields with growth rates even larger than through the traditional Biermann battery.
