Neutron matter at densities on the order of the nuclear saturation density is believed to have neutrons paired in the ³P₂ channel. We study the low-lying modes of this phase and find two massless modes (angulons), resulting from the spontaneous breaking of rotational symmetry as well as three other gapped modes. Here, we compute their masses at arbitrary temperatures.
