【 摘 要 】

We have studied the evolution of cosmological parameters by considering exponential harmonic field with collisional matter. A comparison has been made with the behavior of these parameters in the presence of ordinary matter and the model $\Lambda CDM$. We have also compared the evolution of these parameters with the ones obtained in the modified gravity $f (R)$ and $f (R, T)$ theory case. The results are in line with those of the modified gravity so that the harmonic exponential field can be used to explain why the Universe has gone from the deceleration phase to the acceleration phase.
