Geons as wormholes of modified gravity |
|
Abstract |
Wormholes may arise as solutions of extensions of General Relativity without violation of the energy conditions. Working in a metric-affine framework, which is experimentally supported by the physics of crystalline structures with defects, we consider explicit models supporting such solutions in four and higher dimensions. It is shown that they actually represent explicit realizations of the concept of geon introduced by Wheeler, interpreted as topologically non-trivial self-consistent bodies generated by an electromagnetic field without sources. Several of their properties are discussed. |
