Wormholes supported by hybrid metric-Palatini gravity
Wormholes supported by hybrid metric-Palatini gravity
Recently, a modified theory of gravity was presented, which consists of the superposition of the metric Einstein-Hilbert Lagrangian with an $f(\mathcal{R})$ term constructed \`a la Palatini. The theory possesses extremely interesting features such as predicting the existence of a long-range scalar field, that explains the late-time cosmic acceleration and passes …
