Geometric structure of the generic static traversable wormhole throat
David Hochberg,Matt Visser +1 more
TL;DR: It is shown that topology is too limited a tool to accurately characterize a generic traversable wormhole: in general one needs geometric information to detect the presence of a wormhole, or more precisely to locate the wormhole throat.
Journal ArticleDOI
Dynamic wormholes, anti-trapped surfaces, and energy conditions
David Hochberg,Matt Visser +1 more
TL;DR: In this article, a local definition of wormhole throats, free from assumptions about asymptotic flatness, symmetries, future and past null infinities, embedding diagrams, topology, and even time dependence is developed that accurately captures the essence of what a wormhole throat is and where it is located.
Journal ArticleDOI
Null Energy Condition in Dynamic Wormholes
David Hochberg,Matt Visser +1 more
TL;DR: It is shown that the analysis can be phrased purely in terms of local geometry at and near the wormhole throat, and it does not have to make any technical assumptions about asymptotic flatness or other global properties.
Journal ArticleDOI
Self-Consistent Wormhole Solutions of Semiclassical Gravity
TL;DR: In this paper, a self-consistent solution of the semiclassical Einstein field equations corresponding to a Lorentzian wormhole coupled to a quantum scalar field is presented.
Journal ArticleDOI
Frank Model and Spontaneous Emergence of Chirality in Closed Systems
TL;DR: These features, together with the response of the system to a sequential reaction procedure, suggest that a similar type of network is at the heart of the Soai reaction.
