Power-law cosmology in Weyl-type $f(Q,T)$ gravity

Understand

Gravity is attributed to the spacetime curvature in classical General Relativity (GR).

• But, other equivalent formulation or representations of GR, such as torsion or non-metricity have altered the perception.
• We consider the Weyl-type $f(Q, T)$ gravity, where $Q$ represents the non-metricity and $T$ is the trace of energy momentum temsor, in which the vector field $\omega_{\mu}$ determines the non-metricity $Q_{\mu \nu \alpha}$ of the spacetime.
• In this work, we employ the well-motivated $f(Q, T)= \alpha Q+ \frac{\beta}{6k^{2}} T$, where $\alpha$ and $\beta$ are the model parameters.
