Non-Equilibrium Phase Transitions and Domain Walls
D. Coulson, Z. Lalak, B. Ovrut
Non-equilibrium phase transitions of a scalar field in an expanding spacetime are discussed. These transitions are shown to lead, for appropriate potential energy functions, to a b…

Temperature Anisotropies in a Universe with Global Defects
David Coulson
We present a technique of calculating microwave anisotropies from global defects in a reionised universe. We concentrate on angular scales down to one degree where we expect the no…
