Thin walls in regions with vacuum energy
Abstract
The motion of a thin wall is treated in the case where the regions on either side of the wall have vacuum energy. This treatment generalizes previous results involving domain walls in vacuum and also previous results involving the properties of false vacuum bubbles. The equation of state for a domain wall is tau = sigma, where tau is the tension in the wall and sigma is the energy density. The motion of a more general class of walls is also considered. Spherically symmetric and planar symmetric walls are examined.
