Oscillating bounce solutions and vacuum tunneling in de Sitter spacetime
Oscillating bounce solutions and vacuum tunneling in de Sitter spacetime
We study a class of oscillating bounce solutions to the Euclidean field equations for gravity coupled to a scalar field theory with two, possibly degenerate, vacua. In these solutions the scalar field crosses the top of the potential barrier $k>1$ times. Using analytic and numerical methods, we examine how the …
