WebMar 16, 2024 · The bumblebee gravity model is a vector–tensor gravitational theory that serves as an alternative to Einstein's general relativity (GR). The vector field, called the bumblebee field, in the theory enters the action the same way as the electromagnetic (EM) four-potential, only that the bumblebee field B μ couples to the Ricci tensor R μ ν … WebNov 7, 2024 · We have obtained an exact vacuum solution from a gravity sector contained in the minimal standard-model extension. The theoretical model assumes a Riemann spacetime coupled to the bumblebee field which is responsible for the spontaneous Lorentz symmetry breaking.
WebJun 14, 2024 · In the framework of the bumblebee gravity theory, the spontaneous Lorentz symmetry breaking is induced by a vector B_ {\mu } with a non-zero nonzero vacuum expectation value. Through a coupling, the bumblebee vector field B_ {\mu } would affect the dynamics of the gravitational field.
