TL;DR
This paper explores how wormholes can be induced on a four-dimensional brane within a five-dimensional spacetime, showing they are supported by bulk effects rather than on-brane matter, using the Nakas-Kanti approach.
Contribution
It demonstrates the generation of Morris-Thorne and Molina-Neves wormholes on the brane via the Nakas-Kanti method, highlighting bulk influence as their cause.
Findings
Wormholes are induced on the brane from a five-dimensional bulk.
These wormholes are supported by bulk effects, not on-brane matter.
The Nakas-Kanti approach effectively derives known wormhole solutions in brane-world scenarios.
Abstract
In a brane-world context in which our universe would be a four-dimensional brane embedded into a five-dimensional spacetime or bulk, wormhole geometries are induced on branes. In this article, the Morris-Thorne wormhole and the Molina-Neves wormhole are obtained on the brane using the Nakas-Kanti approach, which starts from a regular five-dimensional spacetime to obtain known black hole and wormhole solutions on the four-dimensional brane. From the bulk perspective, these wormholes are five-dimensional solutions supported by an exotic fluid, but from the brane perspective, such objects are wormholes not supported by any fields or particles that live on the four-dimensional spacetime. Thus, the cause of these wormholes is the bulk influence on the brane.
