Query: Fractional magnetoresistance oscillations in spin-triplet
  superconducting rings   We theoretically study the magnetoresistance of mesoscopic spin-triplet
superconducting rings resulting from thermal vortex tunneling below the
critical temperature. Utilizing the London limit of Ginzburg-Landau theory, we
allow the fluxoid of the ring to take both integer and half-integer values for
both the usual charge supercurrent and the spin supercurrent that is unique to
spin-triplet superconductors. At the lowest temperatures, we find that the
magnetoresistance oscillates with the standard periodicity $\Phi_0 = h / 2e$
but also acquires a characteristic two-peak structure. Strikingly, we further
identify an intermediate temperature range in which the magnetoresistance
oscillations have an emergent fractional periodicity $\Phi_0 / n$ in the
presence of disorder, where the integer $n \geq 3$ is determined by the ratio
of the spin and charge superfluid densities. These fractional oscillations
directly reflect not only the enlarged number of available fluxoid states in
spin-triplet superconductors but also the tunneling of unconventional
half-quantum vortices harboring Majorana zero modes.
