Universe as a domain wall
It is shown that the effective five-dimensional theory of the strongly coupled heterotic string is a gauged version of N51 five-dimensional supergravity with four-dimensional boundaries. For the universal supermultiplets, this theory is explicitly constructed by a generalized dimensional reduction procedure on a Calabi-Yau manifold. A crucial ingredient in the reduction is the retention of a ‘‘...
متن کاملThe Universe as a Domain Wall
It is shown that the effective five–dimensional theory of the strongly coupled heterotic string is a gauged version of N = 1 five–dimensional supergravity with four–dimensional boundaries. For the universal supermultiplets, this theory is explicitly constructed by a generalized dimensional reduction procedure on a Calabi-Yau manifold. A crucial ingredient in the reduction is the retention of a ...
متن کاملBouncing Universe with a Nonminimally Coupled Scalar Field on a Moving Domain Wall
We study dynamics of a dark energy component nonminimally coupled to gravity on a moving domain wall. We use this setup to explain late-time accelerated expansion and crossing of the phantom divide line by the equation of state parameter of this non-minimally coupled dark energy component. By analyzing parameter space of the model, we show that this model accounts for accelerated expansion and ...
متن کاملThe brane as a Higgs domain wall: ideas and issues
The most obvious field-theoretic model for a brane is a scalar field domain wall or kink. I discuss how this idea can be connected with spontaneous internal symmetry breaking via a mechanism called the “clash of symmetries”. Compatibility with Randall and Sundrum’s warped metric alternative to compactification is then demonstrated. I end with brief remarks about open questions.
