摘要：
凝聚态系统可以承载具有粒子、场和维度不同于我们所居住宇宙的涌现“真空”。受具有电荷和磁荷的涌现规范场出现的启发，我们考虑在存在磁单极的情况下二维电磁学的命运。我们发现，通常情况下电磁场因电阻效应而衰减。然而，我们仍然可以识别出一个磁流体力学区域。它展现出磁声波，与d=3中不同，这些波是各向同性的，系统中存在的奇粘滞系数对其有贡献。此外，我们发现了一种发电机作用，与d=3不同，它需要流动的可压缩性。
英文摘要：
Condensed matter systems can host emergent `vacua' with particles, fields and dimension different from that of the universe we inhabit. Motivated by the appearance of emergent gauge fields with both electric and magnetic charges, we consider the fate of electromagnetism in two dimensions in the presence of magnetic monopoles. We find that generically electromagnetic fields are damped due to resistive effects. However, we can still identify a magnetohydrodynamic regime. It exhibits magnetosonic waves which, unlike in $d=3$, are isotropic, to which there is a contribution from the odd viscosity coefficient present in the system. Further, we find a dynamo action, which unlike in $d=3$ requires compressibility of the flow.
