Nucleation of de Sitter from the anti de Sitter spacetime in scalar field models

We show that, in the framework of Einstein-scalar gravity, the de Sitter (dS) spacetime can be nucleated out of the anti de Sitter (AdS) one. This is done by using a scalar lump solution, which has an \(\text{AdS}_4\) spacetime in the core, allows for \(\text{dS}_4\) vacua and was found to be plague...
