Relativistic energy density functionals provide a universal self-consistent description of nuclear ground states across the nuclear chart. The resulting ground states can be to obtain the excited states of the nucleus. These excited states play a major role in determining the cross sections of low-energy neutrino-nucleus interactions. The interaction is described by a charged-current weak Hamiltonian, whose nuclear transition matrix elements determine the nuclear response. In this work, we use the relativistic quasiparticle random-phase approximation to obtain the excited states and use them to calculate the charge-exchange neutrino-nucleus cross sections for nuclei relevant to astrophysical processes and neutrino detection.
