Domain walls in Horndeski gravity

Blog Article

The Horndeski gravity yields domain wall solutions that connect asymmetric vacua for a certain region of parameters.In the thin wall limit there exist BPS domain esp ltd sd-2 walls that connect stable vacua.That is, the false vacua in this theory follows the same ryse disposable effect obtained in supergravity vacua, i.e.

, it does not decay according to Coleman-de Luccia theory and the BPS solutions interpolating different vacua, e.g., non-degenerate AdS vacua, are static infinite planar domain walls separating vacua associated with different spacetimes.
