de Sitter and double asymmetric brane worlds

Abstract: Asymmetric brane worlds with dS expansion and static double kink topology are obtained from a recently proposed method and their properties are analyzed. These domain walls interpolate between two spacetimes with different cosmological constants. In the dynamic case, the vacua correspond to dS and AdS geometry, unlike the static case where they correspond to AdS background. We show that is possible to confine gravity on such branes. In particular, the double brane world host two different walls, so that the gr… Show more

“…The potentials (38) and (39) with the metrics warped factors (36) and (37), that corresponds to the scalar "kink" fields (34) and (35) are very similar in shape to the former solution (33), (30) and (28) plotted in Fig. 1.…”

“…The first solution (28), (30) and (33) is the vortex version of the domain wall solution in [31] where δ could be seen as the string thickness and β as a parameter depending on the cosmological constant. The second solution (34), (36) and (38) has a quartic polynomial potential that is almost identical to the mexican hat potential.…”

“…This set of equations is identical with the field equations of the de Sitter thick brane in the Riemann geometry [13,40,41,42,43,44,45,46]. Here, we can achieve a Z 2 -symmetric solution refer to z coordinate when we consider a symmetric domain wall de Sitter expansion in five dimensions for a sine-Gordon potential [47,48] …”
