A new pressure-parametrization unified dark fluid model
  We propose a new pressure-parametrization model to explain the accelerated
expansion of the late-time Universe by considering the dark contents (dark
matter and dark energy) as a unified dark fluid. To realize this model more
physically, we reconstruct it with the quintessence and phantom scalar fields,
respectively. We use the recent cosmological data to constrain this model,
distinguish it from the standard cosmological model and find that the value of
the Hubble constant $H_0=68.34^{+0.53}_{-0.92}$ supports the global measurement
by the Planck satellite at the $1\sigma$ confidence level.
