Holographic dark energy in Einstein-Cartan spin cosmology
Yongjun Yun, Jungjai Lee
We show that, in Einstein-Cartan theory, the torsion scalar modifies the dust-like equation of state of non-interacting holographic dark energy with the Hubble radius as the infrar…

Dynamical Resolution of the Cosmic Coincidence Problem in Non-Interacting Holographic Dark Energy via Einstein-Cartan Torsion
Yongjun Yun, Kyungduk Kim, Jungjai Lee
We investigate the cosmic coincidence problem in non-interacting holographic dark energy with the Hubble radius as the infrared cutoff in Einstein-Cartan gravity. In general relati…

Holographic Dark Energy with Hubble Radius as an Infrared Cutoff in Einstein-Cartan Gravity
Yongjun Yun, Jungjai Lee
In this work, we investigate non-interacting holographic dark energy (HDE) with the Hubble radius as the infrared cutoff in Einstein-Cartan gravity. We derive the Einstein-Cartan e…
