From a cosmic perspective, we are all citizens of the one small and lonely planet Earth, and we all face some major global challenges. Some of them may even threaten the future of our civilization, such as climate change and nuclear weapons, to name

Former Prime Minister Kevin Rudd reaffirmed Australia's commitment to realising a world free from nuclear weapons. Arguments are presented here that this aim cannot be achieved until the framework of international law and international governance has

We highlight the surprising similarities between particle physics and condensed matter physics which have been emerging from recent advances in experimantal and theoretical techniques.

The search for exotic quantum magnetism in models and real materials has been a very active area of research over the last few decades. We argue that multiparticle excitation spectra are crucial in identifying exotic features, such as spin fractional

The extreme anisotropic limit of Euclidean SU(3) lattice gauge theory is examined to extract the Hamiltonian limit, using standard path integral Monte Carlo (PIMC) methods. We examine the mean plaquette and string tension and compare them to results

The Numerical calculations for tadpole-improved U(1) lattice gauge theory in three-dimensions on anisotropic lattices have been performed using standard path integral Monte Carlo techniques. Using average plaquette tadpole renormalization scheme, sim

Energy eigenvalues and order parameters are calculated by exact diagonalization for the transverse Ising model on square lattices of up to 6x6 sites. Finite-size scaling is used to estimate the critical parameters of the model, confirming universalit

Series expansions at $T=0$ are used to study properties of the half-filled $t\ensuremath{-}J$ ladder doped with one or two holes, and at quarter filling. Dispersion curves are obtained for one-hole symmetric and antisymmetric (bonding and antibonding
