A Time-Dependent Canonical Transformation between Bateman and Doubled Caldirola--Kanai Systems for a Homogeneous Massive Scalar Field on a Prescribed FLRW Background
Narakorn Kaewkhao, Chaiyaphat Phantusen
Dissipative equations admit distinct variational descriptions in the Bateman and Caldirola--Kanai (CK) formalisms. The classical correspondence between them is extended to a homoge…
Analytical Solutions to the Wheeler-DeWitt Equation in Rosen-Lagrangian Cosmology via the Eisenhart Lift
Narakorn Kaewkhao, Suparat Marit, Phongpichit Channuie
The Rosen Lagrangian framework promotes the cosmological constant to a scale-factor-dependent quantity, , thereby providing a dynamical dark energy scenario for $…
Traversable Wormholes in Einstein-Euler-Heisenberg Gravity: Geometry, Energy Conditions, and Gravitational Lensing
Phongpichit Channuie, Allah Ditta, Narakorn Kaewkhao +1
In this study, we investigate traversable wormholes within the framework of Einstein-Euler-Heisenberg (EEH) nonlinear electrodynamics. By employing the Einstein field equations wit…
Scalar Field Dynamics in Non-Minimally Coupled Theories via the Noether Symmetry and the Eisenhart-Duval Lift
Ahmadfikri Talek, Narakorn Kaewkhao, Watcharakorn Srikom +2
This study investigates the dynamics of a non-minimally coupled (NMC) scalar field in modified gravity, employing the Noether gauge symmetry (NGS) approach to systematically derive…
