摘要:
The aim of this paper is to discuss stability of regular thin-shell wormholes coupled with non-linear electrodynamics and cosmological constant. The surface stresses are formulated by using Lanczos equations. We examine attractive and repulsive behavior of these constructed wormholes corresponding to outward and inward-directed acceleration components, respectively. We also investigate stability conditions for the existence of traversable thin-shell wormholes with arbitrarily small amount of different fluids as exotic matter. We consider linear, logarithmic and Chaplygin gas models and find that a modified generalized Chaplygin gas model provides maximum viable regions for stability of the respective thin-shell wormholes. It is found that formation of stable regions for ABGB thin-shell wormholes highly depends on the physically acceptable range of charge and other parameters.
