A mean-field method for driven diffusive systems based on maximum entropy principle
Here, we propose a method for generating a hierarchy of mean-field approximations to study the properties of the driven diffusive Ising model at nonequilibrium steady state. In addition, the present study offers a demonstration of the practical application of the information theoretic methods to a …

Mean-Field Parameter Study of Radiation-Induced Segregation in a Binary Metal Alloy
… IV (Gen-IV) nuclear reactor designs. A mean-field study is conducted on a body-centered cubic (BCC) A-B binary metal alloy system. The performance of the simulated metal system is measured by assessing the degree of segregation that occurs at the grain boundary (GB) in the center of the …

Improving radiation resistance of solid solutions by addition of defect trapping solutes: Atomistic simulations and continuum modeling
… but may be calculated using the self-consistent mean-field method (SCMF), which is implemented in the software KineCluE. Here we introduce an improvement to KineCluE which allows for automatic calculation of the system energetics based on an interatomic potential. This greatly facilitates …

Aspects of the Ising and tricritical Ising models
… function in the Ising model. We <br/>present a method which provides the well-known standard solutions by a new and efficient route. The second part of the thesis is concerned with off-critical behaviour, and in particular the numerical study of perturbations of conformal field theory through …
