标题： Carroll swiftons

摘要： 我们构建了Carroll不变的理论，其中场传播在Carroll光锥之外，即速度严格大于零（称为“Carroll swiftion”）。我们首先考虑平坦Carroll时空中的模型，一般维度下，给出了标量和矢量Carroll swiftion场理论。然后我们转向与引力的耦合，在二维情况下，通过适当地将其与Carroll标度引力耦合，得到了一个Carroll不变的标量swiftion。它对几何的反作用生成了动力学的挠率。 显示英文摘要

摘要： We construct Carroll-invariant theories with fields propagating outside the Carroll lightcone, i.e., at a speed strictly greater than zero (`Carroll swiftons'). We first consider models in flat Carroll spacetime in general dimensions, where we present scalar and vector Carroll swifton field theories. We then turn to the coupling to gravity and achieve in particular in two dimensions a Carroll invariant scalar swifton by coupling it suitably to Carroll dilaton gravity. Its backreaction on the geometry generates dynamical torsion.
