Abstract
We investigate the collective excitations in spin-one color superconductors. We classify the Nambu-Goldstone modes by the pattern of spontaneous symmetry breaking, and then use the Ginzburg-Landau theory to derive their dispersion relations. These soft modes play an important role for the low-energy dynamics of the system such as the transport phenomena and hence are relevant for late-stage evolution of neutron stars. In the case of the color-spin-locking phase, we use a functional technique to obtain the low-energy effective action for the physical Nambu-Goldstone bosons that survive after gauging the color symmetry.
