Anisotropic dark energy universe in f(Q, T) gravity with observational constraints

Aim of this paper is to investigate an anisotropic locally rotationally symmetric (LRS) Bianchi type-I space-time in the context of the recently proposed f(Q, T) gravity, where Q is the non-metricity scalar and T is energy-momentum tensor. We have considered f(Q, T) = alpha Q + beta T a linear form, where alpha and beta are model parameters. We have analyzed the exact solution of LRS Bianchi type-I space-time by assuming relation between metric potential A = B-n, where n is arbitrary non-zero real number. To study the anisotropic nature of the dynamical dark energy, we assume that the skewness parameters are time dependent and n not equal 1. We have constrained to our model by using observational Hubble dataset. Onwards, discussed the physical behavior of cosmological parameters such as energy density, pressure, EoS parameter, deceleration parameter and, Energy conditions.
