Unified Lagrangian for Tachyon, Quintessence, and Phantom Scalar Fields

2023 · arXiv (Cornell University)

This paper presents a novel unified Lagrangian density that combines the behaviors of tachyon, quintessence, and phantom scalar fields within the realms of theoretical physics and cosmology. The unified Lagrangian is formulated, where \(f(α)\) is …
