On the formation of non-topological string networks
Ana Achúcarro, Julian Borrill, Andrew R. Liddle
We review recent simulations of the formation of a particular class of non-topological defects known as semilocal strings during a phase transition. Semilocal strings have properti…
A Fast Method For Bounding The CMB Power Spectrum Likelihood Function
Julian Borrill
As the Cosmic Microwave Background (CMB) radiation is observed to higher and higher angular resolution the size of the resulting datasets becomes a serious constraint on their anal…
The formation rate of semilocal strings
Ana Achucarro, Julian Borrill, Andrew R Liddle
We carry out three-dimensional numerical simulations to investigate the formation rate of semilocal strings. We find that the back-reaction of the gauge fields on the scalar field…
Prediction of a Strain Induced Conduction Band Minimum in Embedded Quantum Dots
A. J. Williamson, Alex Zunger, A. Canning
Free standing InP quantum dots have previously been theoretically and experimentally shown to have a direct band gap across a large range of experimentally accessible sizes. We dem…
