Dark Energy as a Critical Phenomenon: a Resolution for Hubble Tension
Abdolali Banihashemi, Nima Khosravi, Arman Shafieloo
We propose a dark energy model based on the physics of critical phenomena which is consistent with both the Planck's CMB and the Riess et al.'s local Hubble measurements. In this m…

Ginzburg-Landau Theory of Dark Energy: A Framework to Study Both Temporal and Spatial Cosmological Tensions Simultaneously
Abdolali Banihashemi, Nima Khosravi, Amir H. Shirazi
A dark energy model (DE) is proposed based on Ginzburg-Landau theory of phase transition (GLT). This model, GLTofDE, surprisingly provides a framework to study not only temporal te…

Ups and Downs in Dark Energy: phase transition in dark sector as a proposal to lessen cosmological tensions
Abdolali Banihashemi, Nima Khosravi, Amir H. Shirazi
Based on tensions between the early and late time cosmology, we proposed a double valued cosmological constant which could undergo a phase transition in its history. It is named "d…
