• # Abstract

The work is the study of Bianchi type-I models with holographic dark energy in the framework of $f(R)$ theory of gravitation. The exact solutions of the field equations are deduced by considering the exponential and power-law volumetric expansion. Various physical and kinematical properties of the models are discussed. In addition to make our interpretation more clear for that we have taken the state finder diagnostic pair $\{r; s\}$ and cosmic jerk parameter $j(t)$ to characterize different phases of the universe. The holographic scalar fields of dark energy are reconstructed and quintessence potential for both the modelsdescribing accelerated expansion of the universe is also obtained.

Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
