Domain walls from ten dimensions
We write down the general conditions for N = 1 supersymmetric four– dimensional domain walls, deriving them from a ten–dimensional point of view using generalized complex geometry. In cases where the compactification allows for a truncation to a finite number of fields, we make contact with a four–dimensional effective description. In the context of the AdS/CFT correspondence, the equations can...
متن کاملDomain Walls and Solitons in Odd Dimensions
We discuss a consistency condition for the existence of smooth soliton solutions which interpolate between vacua in odd-dimensional theories. In particular we apply this analysis to a wide class of supergravities to rule out the existence of smooth domain walls interpolating between supersymmetric vacua. Normale Supérieure.
متن کاملSkyrmions and domain walls in ( 2 + 1 ) dimensions
We study classical solutions of the vector O(3) sigma model in (2 + 1) dimensions, spontaneously broken to O(2) × Z2. The model possesses Skyrmion-type solutions as well as stable domain walls which connect different vacua. We show that different types of waves can propagate on the wall, including waves carrying a topological charge. The domain wall can also absorb Skyrmions and, under appropri...
متن کاملDomain Walls from M-branes
We discuss the vertical dimensional reduction of M-branes to domain walls in D = 7 and D = 4, by dimensional reduction on Ricci-flat 4-manifolds and 7-manifolds. In order to interpret the vertically-reduced 5-brane as a domain wall solution of a dimensionally-reduced theory in D = 7, it is necessary to generalise the usual Kaluza-Klein ansatz, so that the 3-form potential in D = 11 has an addit...
متن کاملBaryogenesis from Unstable Domain Walls
. -ABSTRACT _ There exists a class of cosmic strings that turn matter into antimatter (Alice strings). In a GUT where the unbroken gauge group contains charge conjugation (C), such strings form when a phase transition renders C a discrete symmetry. They become boundaries of domain walls at a later, C-breaking transition. These ‘Alice walls’ are cosmologically harmless, but -. can play an import...
