Runaway dilatonic domain walls
We explore the stability of domain wall and bubble solutions in theories with compact extra dimensions. The energy density stored inside of the wall can destabilize the volume modulus of a compactification, leading to solutions containing either a timelike singularity or a region where space decompactifies, depending on the metric ansatz. We determine the structure of such solutions both analyt...
متن کاملFlat world of dilatonic domain walls.
We study dilatonic domain walls specific to superstring theory. Along with the matter fields and metric the dilaton also changes its value in the wall background. We found supersymmetric (extreme) solutions which in general interpolate between isolated superstring vacua with non-equal value of the matter potential; they correspond to the static, planar domain walls with flat metric in the strin...
متن کاملLocalization of Bulk Form Fields on Dilatonic Domain Walls
We study the localization properties of bulk form potentials on dilatonic domain walls. We find that bulk form potentials of any ranks can be localized as form potentials of the same ranks or one lower ranks, for any values of the dilaton coupling parameter. For large enough values of the dilaton coupling parameter, bulk form potentials of any ranks can be localized as form potentials of both t...
متن کاملBulk Fields in Dilatonic and Self-Tuning Flat Domain Walls
We study the Kaluza-Klein zero modes of massless bulk fields with various spins in the background of dilatonic and self-tuning flat domain walls. We find that the zero modes of all the massless bulk fields in such domain wall backgrounds are normalizable, unlike those in the background of the non-dilatonic domain wall with infinite extra space of Randall and Sundrum. In particular, gravity in t...
متن کاملLocalization of Gravity on Dilatonic Domain Walls: Addendum to “Solitons in Brane Worlds”
We supplement the discussion on localization of gravity on dilatonic domain walls in “Solitons in Brane Worlds” (Nucl. Phys. B576, 106, hep-th/9911218) by giving unified and coherent discussion which combines the result of this paper and the expanded results in the author’s subsequent papers in an attempt to avoid misleading readers. We also discuss the possible string theory embeddings of the ...
