Energy gap of the bimodal two-dimensional Ising spin glass (2008)
An exact algorithm is used to compute the degeneracies of the excited states of the bimodal Ising spin glass in two dimensions. It is found that the specific heat at arbitrary low temperature is not...
Domain wall entropy of the bimodal two-dimensional Ising spin glass (2007)
We report calculations of the domain wall entropy for the bimodal two-dimensional Ising spin glass in the critical ground state. The L * L system sizes are large with L up to 256. We find that it is...

Lanthanide contraction and magnetism in the heavy rare earth elements. (2007)
Hughes, I. D., Däne, M., Ernst, A., Hergert, W., Lüders, M., Poulter, J., ...
We introduce an exact algorithm for the computation of spin correlation functions for the two dimensional +/-J Ising spin glass in the ground state. Unlike with the transfer matrix method, there is...
Mangetic properties of Ising thin-films with cubic lattices (2003)
Laosiritaworn, Y., Poulter, J., Staunton, J. B.
We have used Monte Carlo simulations to observe the magnetic behaviour of Ising thin-films with cubic lattice structures as a function of temperature and thickness especially in the critical region....
The easy axis of the magnetic response of the conduction electrons of yttrium and rare earths (2003)
Thakor, V., Staunton, J. B., Poulter, J., Ostanin, S., Ginatempo, B., Bruno, Ezio
We describe a scheme for first-principles calculations of the static, paramagnetic, spin susceptibility of metals with relativistic effects such as spin-orbit coupling included. This gives the...
Thakor, V., Staunton, J. B., Poulter, J., Ostanin, S., Ginatempo, B., Bruno, Ezio
We present an ab initio theoretical formalism for the static paramagnetic spin susceptibility of metals at finite temperatures. Since relativistic effects, e.g. spin-orbit coupling, are included, we...
Staunton, J. B., Poulter, J., Ginatempo, B., Bruno, E., Johnson, D. D.
We describe our theoretical formalism and computational scheme for making ab-initio calculations of the dynamic paramagnetic spin susceptibilities of metals and alloys at finite temperatures. Its...
Staunton, J. B., Poulter, J., Ginatempo, B., Bruno, E., Johnson, D. D.
A scheme for making ab-initio calculations of the dynamic paramagnetic spin susceptibilities of solids at finite temperatures is described. It is based on Time-Dependent Density Functional Theory and...

ON THE GROUND STATE PROPERTIES OF THE ± J ISING MODEL (1988)
In the combinatorial method or Grassmann algebra formalism the ground state properties of the ± J Ising model can be expressed in terms of the behaviour of the eigenvectors of a matrix. It is shown...
