摘要 | Sanchez and Lacombe have developed a lattice fluid theory based on a well-defined statistical mechanical model. Taking the lattice fluid as a candidate of dark energy, we investigate the cosmic evolution of this fluid. Using the combined observational data of Type Ia Supernova (SNe Ia) Union2.1, Baryon Acoustic Oscillations (BAO) data from 6dFGS, SDSS and WiggleZ survey, and Observational Hubble Data (OHD), we find the best fit value of the parameters: A = -0.3 +/- 0.2(1 sigma) +/- 0.4(2 sigma) +/- 0.8(3 sigma) and Omega (m) = 0.31 +/- 0.02(1 sigma) +/- 0.05(2 sigma) +/- 0.07(3 sigma). The cosmological implications of the model are presented. |
