Description
The nature of dark energy, which constitutes about 68% of the universe’s total energy, remains one of the most profound mysteries in cosmology. Scalar fields with power law potentials are promising candidate for dark energy. For understanding the dynamics of scalar fields we begin with a general form of power law potential V (ɸ) =V0 ɸ n and try to determine critical points and analyze their stability. Further we analyze the phase plane by plotting the trajectories around the critical points which provide insights into possible evolutionary paths of the scalar field and reveals attractor solutions that can drive prolonged periods of inflation or accelerate the late-time expansion of the universe.
