Topic: Smooth sign-switching dark energy models are investigated for their potential to alleviate the Hubble tension by modifying the late-time expansion history.
Topic: k-essence theories are explored as a viable dark energy model that robustly alleviates the Hubble tension.
Topic: Strong gravitational lensing observations are used to constrain interacting dark energy models, which propose an interaction between dark matter and dark energy to address cosmological tensions.
