Carrollian limit of quadratic gravity

Original language description

We study the Carrollian limit of the (general) quadratic gravity in four dimensions. We find that in order for the Carrollian theory to be a modification of the Carrollian limit of general relativity, the parameters in the action must depend on the speed of light in a specific way. By focusing on the leading and the next-toleading orders in the Carrollian expansion, we show that there are four such nonequivalent Carrollian theories. Imposing conditions to remove tachyons (from the linearized theory), we end up with a classification of Carrollian theories according to the leading-order and next-to-leading-order actions. All modify the Carrollian limit of general relativity with quartic terms of the extrinsic curvature. To the leading order, we show that two theories are equivalent to general relativity, one to R + R2 theory and one to the general quadratic gravity. To the next-to-leading order, two are equivalent to R + R2 while the other two are equivalent to the general quadratic gravity. We study the two theories that are equivalent to R + R2 to the leading order and write their magnetic limit actions.
