AI总结:

本文通过二阶表述研究2+1维偶极Chern-Simons理论,构建与亚里士多德几何耦合的弯曲时空分形子规范理论,并给出高维推广及电单极子解。

摘要:

我们研究2+1维中含与不含宇宙学常数的偶极Chern-Simons理论。我们将该理论写成二阶表述,并表明这会产生一种与亚里士多德几何耦合的分形子规范理论,该理论也可与物质耦合。这种耦合展现出显著性质:将偶极规范不变性推广到弯曲时空,而不对可能的几何施加任何限制。我们还利用二阶表述构建了作用量的高维推广。最后,对于(2+1)维Chern-Simons理论,我们找到解并将其解释为电单极子,分析其电荷,并论证渐近对称性是无限维的。

英文摘要:

We study dipole Chern-Simons theory with and without a cosmological constant in $2+1$ dimensions. We write the theory in a second order formulation and show that this leads to a fracton gauge theory coupled to Aristotelian geometry which can also be coupled to matter. This coupling exhibits the remarkable property of generalizing dipole gauge invariance to curved spacetimes, without placing any limitations on the possible geometries. We also use the second order formulation to construct a higher dimensional generalization of the action. Finally, for the $(2+1)$-dimensional Chern-Simons theory we find solutions and interpret these as electric monopoles, analyze their charges and argue that the asymptotic symmetries are infinite-dimensional.
