摘要
In this work, we investigate the dynamics of Bianchi type VI0 space-time in the framework of f(R, T) theory of gravity where R stands for Ricci scalar and T stands for the trace of the stress energy-momentum tensor with Modified Renyi Holographic Dark Energy (MRHDE). With the specific choice of the functional f(R, T) = f1(R) + f2 (T) = μ1R+ μ2T where f1(R) and f2 (T) are arbitrary functions of R and T respectively and μ1 and μ2 are two parameters, we have obtained the exact solutions of the model by considering the energy density of MRHDE and by using a law of variation for the Hubble parameter H. It is found that our model leads to the accelerated expansion of the Universe. The EOS parameter ωDE > -1 DE indicates that our cosmological model behaves like a quintessence dark energy model which is consistent with the recent observations. A correspondence between MRHDE and quintessence dark energy is established. The quintessence dynamics of the potential and scalar field are reconstructed, which illustrates the late-time cosmic acceleration. All physical parameters are calculated and discussed graphically.
