The ground state of chains with antiferromagnetic XY interactions is examined by direct diagonalisation of the Hamiltonian. Attention is focussed on chains with nearest and next-nearest neighbour interactions. It is found that results for finite chai

A course focusing on ethical issues in physics has been taught to undergraduate students at Eastern Michigan University since 1988. The course covers both responsible conduct of research and ethical issues associated with how physicists interact with

A survey was conducted of a subset of the physics community in order to gain insight into attitudes towards integrating ethics into the physics curriculum. The results indicated significant support among some groups for such an integration yet also r

Physics Education Research is a form of social science research in that it uses human subjects. As physicists we need to be aware of the ethical and legal ramifications of performing this research, taking into account the fundamental differences betw

The majority of the layers of a multilayer optical coating typically have optical thicknesses equal to one quarter of the appropriate wavelength of radiation. Replacing this constraint with the stipulation that a pair of adjacent layers should have a

A photophysical model for describing the absorption of light by melanin based on the mechanisms of sequential two-photon absorp- tion is investigated. The process involves a conversion of the photon energy in a photochemical effect such as photodisso

Previous research on highly reflective multilayer optical coatings has shown that varying the thickness of layers from their traditional quarter-wave values gives the potential for greater damage thresholds without sacrificing the desired optical pro
