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…
Majoron Dark Energy via Freezing Induced by Quantum Coherence
Keunsu Cheon, Sin Kyu Kang, Jungjai Lee
We propose a nonequilibrium mechanism for Majoron dark energy in which the late-time freezing of a physical Majoron is induced by quantum coherence in a hidden pseudo-Dirac sterile…
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…
Non-interacting holographic dark energy with Torsion via Hubble Radius
Yongjun Yun, Jungjai Lee
We reconstruct a holographic dark energy model within a Friedmann cosmology incorporating torsion scalar, assuming no interaction between dark energy and dark matter. Setting the H…
Electromagnetism from relativistic fluid dynamics
Jeongwon Ho, Hyeong-Chan Kim, Jungjai Lee +1
We reformulate classical electromagnetism within the matter-space framework of relativistic fluid dynamics. The central assumption is that the relevant degrees of freedom are encod…
