The Role of Quantum Fluctuations in Defect-Dominated Transitions. (2007)
Cheetham And Copeland, G. J. Cheetham, E. J. Copel, Brighton Bn Qh, T. S. Evans, R. J. Rivers, ...
We examine the effects of quantum fluctuations in second--order phase transitions induced by topological defects. Using the exact solution for static flat walls it is demonstrated that fluctuations...
The Inflationary Energy Scale (2007)
The energy scale of inflation is of much interest, as it suggests the scale of grand unified physics, governs whether cosmological events such as topological defect formation can occur after...
Simulation of Non-Equilibrium Defect Production in Early Universe (2007)
Antunes And, N. D. Antunes, Brighton Bn Qh
We briefly describe how Symmetry Breaking Phase Transitions in the history of the early Universe and in Condensed Matter systems can only be studied at present with the help of Parallel...
Generalised Scalar Field Potentials and Inflation (2007)
Paul Parsons, John D. Barrow, Brighton Bn Qh
We investigate the range of inflationary universe models driven by scalar fields possessing a general interaction potential of the form V (OE) = V 0 OE n exp(\GammaOE m ). Power-law, de Sitter and...
A Quantitative Reconstruction of Boden's Creativity Theory (2007)
1 Introduction to Boden's theory While there is a long tradition of introspective analysis of creativity (e.g.Wallas,1926, Perkins, 1981), recent years have seen the emergence of more principled
Formalising the Slow-Roll Approximation in Inflation (1994)
Andrew R. Liddle, Paul Parsons, John D. Barrow, Brighton Bn Qh
The meaning of the inflationary slow-roll approximation is formalised. Comparisons are made between an approach based on the Hamilton-Jacobi equations, governing the evolution of the Hubble...
Texture-Induced Microwave Background Anisotropies (1994)
Julian Borrill, Edmund J. Copeland, Andrew R. Liddle, Albert Stebbins, Shoba Veeraraghavan, Brighton Bn Qh
We use numerical simulations to calculate the cosmic microwave background anisotropy induced by the evolution of a global texture field, with special emphasis on individual textures. Both spherically...
AI and A-Life: Never Mind The Blocksworld (1994)
This paper discusses the relationship between Artificial Intelligence (AI) and Artificial Life (A-Life). A-Life research addresses a wide range of phenomena, some of which have no obvious bearing on...
Solving Geometric Constraint Systems (1990)
Glenn A. Kramer, Brighton Bn Qh
Finding the configurations of a set of rigid bodies that satisfy a set of geometric constraints is a problem traditionally solved by reformulating the geometry and constraints as algebraic equations...
