THICK PLANAR DOMAIN WALL: ITS THIN WALL LIMIT AND DYNAMICS

Thick Domain Wall Universes

We investigate the spacetime of a thick gravitating domain wall for a general potential V (Φ). Using general analytical arguments we show that all nontrivial solutions fall into two categories: those interpretable as an isolated domain wall with a cosmological event horizon, and those which are pure false vacuum de Sitter solutions. Although this latter solution is always unstable to the field ...

From a Thick to a Thin Supergravity Domain Wall

Within D=4 N=1 supergravity theory we obtain an effective theory of the thin wall limit for a flat domain wall configuration, interpolating between isolated supersymmetric extrema of the matter potential. We focus on the Z2 symmetric flat wall and derive the supersymmetric effective action both in the bulk and on the wall; in the thin wall limit the scalar field, forming the wall, is frozen, an...

Magnetoelectric domain wall dynamics and its implications for magnetoelectric memory

Controlling domain wall pinning in planar nanowires by selecting domain wall type and its application in a memory concept

Domain wall fermions for planar physics

In 2+1 dimensions, Dirac fermions in reducible, i.e. four-component representations of the spinor algebra form the basis of many interesting model field theories and effective descriptions of condensed matter phenomena. This paper explores lattice formulations which preserve the global U(2Nf ) symmetry present in the massless limit, and its breakdown to U(Nf )⊗U(Nf ) implemented by three indepe...
