Introduction
============

Almost two decades ago, distance measurements of type Ia supernovae (SNe Ia) indicated that the universe is undergoing a phase of late-time acceleration [@1; @2]. More recently, this exotic phenomenon remains strongly confirmed by different astrophysical observations, including measurements of baryon acoustic oscillations (BAO) from galaxy surveys, measurements of temperature anisotropies of cosmic microwave background (CMB) radiation, observational Hubble parameter data (OHD), the abundance of galaxy clusters (AGC), and strong and weak gravitational lensing (SGL and WGL). Nonetheless, theoretically, the absence of a reasonable physical mechanism responsible for the late-time accelerated expansion has inspired a great deal of alternatives.

In general, there exist two different approaches to explain the accelerated mechanism in the literature. The first approach is to introduce a new field in the framework of the general theory of relativity (GR), namely, the so-called dark energy. The most straightforward and elegant explanation is the well-known cosmological constant $\Lambda$ model, i.e., the $\Lambda$CDM model, which has been demonstrated to be very successful in depicting many aspects of the observed universe. For example, the
