  - "We show that the abundance and redshift distribution (\U0001D451⁢\U0001D441/\U0001D451⁢\U0001D467)
    of galaxy clusters in future high-yield cluster surveys, combined with the spatial
    power spectrum [\U0001D443\U0001D450⁡(\U0001D458)] of the same clusters, can place
    significant constraints on the evolution of the dark energy equation of state,
    \U0001D464=\U0001D464⁡(\U0001D44E). We evaluate the expected errors on \U0001D464\U0001D44E=−\U0001D451⁢\U0001D464/\U0001D451⁢\U0001D44E
    and other cosmological parameters using a Fisher matrix approach, and simultaneously
    including cluster structure evolution parameters in our analysis. We study three
    different types of forthcoming surveys that will identify clusters based on their
    x-ray emission (such as DUO, the Dark Universe Observatory), their Sunyaev-Zel'dovich
    (SZ) decrement (such as SPT, the South Pole Telescope), or their weak-lensing
    shear (such as LSST, the Large Synoptic Survey Telescope). We find that combining
    the cluster abundance and power spectrum significantly enhances constraints from
    either method alone. We show that the weak-lensing survey can deliver a constraint
    as tight as \U0001D6E5⁢\U0001D464\U0001D44E∼0.1 on the evolution of the dark energy
    equation of state, and that the x-ray and SZ surveys each yield \U0001D6E5⁢\U0001D464\U0001D44E∼0.4
    separately, or \U0001D6E5⁢\U0001D464\U0001D44E∼0.2 when these two surveys are
    combined. For the x-ray and SZ surveys, constraints on dark energy parameters
    are improved by a factor of 2 by combining the cluster data with cosmic microwave
    background anisotropy measurements by Planck, but degrade by a factor of 2 if
    the survey is required to solve simultaneously for cosmological and cluster structure
    evolution parameters. The constraint on \U0001D464\U0001D44E from the weak-lensing
    survey is improved by ∼25% with the addition of Planck data.@eng"
