Traversable Wormholes with Van der Waals Equation of State in <i>f</i>  ( <i>R</i> , <i>L</i> , <i>T</i> ) Gravity

ABSTRACT This work presents a novel traversable wormhole solution within the modified gravity framework of theory, where the gravitational action non‐minimally couples geometry and matter fields. Employing the Van der Waals equation of state to model the exotic matter sustaining the wormhole throat, the field equations are analytically and numerically solved under a constant redshift function assumption. The shape function obtained satisfies all key wormhole conditions: throat regularity, flaring‐out, and asymptotic flatness. Detailed energy condition analyses reveal global violation of the null energy condition by matter, though the modified gravity coupling permits shifting exotic behavior into the geometric sector. Stability is assessed via the volume integral quantifier, speed of sound, and adiabatic index, indicating a physically plausible, stable wormhole structure supported by anisotropic pressures. This study elucidates how tunable matter‐geometry couplings in gravity can minimize exotic matter requirements and offers pathways for potential astrophysical signatures of such wormholes.
