    Dynamical and thermodynamical stability of a charged thin-shell wormhole
    (Springer Science+Business Media, 2024) Ernesto F. Eiroa; Griselda Figueroa-Aguirre; Miguel L. Peñafiel; Santiago Esteban Perez Bergliaffa
    Abstract A study of the dynamical and thermodynamical stability of a charged thin-shell wormhole built by gluing two Reissner–Nordström geometries is presented. The charge on the shell is linearly related to the matter content. For the dynamical stability, a concise inequality is obtained, valid for any barotropic equation of state that relates the pressure with the energy density at the throat. A thermodynamical description of the system is introduced, which leads to the temperature and the electric potentials. Adopting a linear equation of state for the pressure and a definite form for the entropy function, the set of equilibrium configurations that are both dynamically and thermodynamically stable is found.
