Quantum fluctuations in planar domain-wall space-times: A possible origin of primordial preferred direction
Quantum fluctuations planar domain-wall space-times possible origin primordial preferred direction
2011/10/18
We study the gravitational effects of a planar domain wall on quantum fluctuations of a massless scalar field during inflation. By obtaining an exact solution of the scalar field equation in de Sitter...
X-type and Y-type junction stability in domain wall networks
junction stability domain wall networks
2011/10/18
We develop an analytic formalism that allows one to quantify the stability properties of X-type and Y-type junctions in domain wall networks in two dimensions. A similar approach might be applicable t...
We consider the signatures of a domain wall produced in the spontaneous symmetry breaking
involving a dilaton-like scalar field coupled to electromagnetism. Domains on either side of the wall exhibit...
