Geometrically frustrated magnetic materials have attracted scientific interest due to exotic low temperature states such as the spin ice compound Ho$_{2}$Ti$_{2}$O$_{7}$. In this material, spin disorder mimics the proton disorder found in water ice, which exhibits magnetic monopole-like excitations.$^{1}$ Frustration occurs when magnetic ions are arranged in geometries where exchange...

Molecular-dynamics simulations is a particle-based simulation method that is widely used in computational physics and materials science. The strong increase of available computational power makes it possible to perform materials simulations with many millions of atoms. In order to harness the full power of modern CPUs, it is necessary to make use of the available SIMD instruction sets (e.g....

BaTiO3 nanoparticles of a controlled size and structure are synthesised for an electroluminescent device application developed by a collaborator. This device requires BaTiO3 nanoparticles, a narrow size distribution and improved dielectric constant. An experimental study of the material’s dielectric constant reports an increase when the particle size approaches 70 nm [1]. This property will...

Nearing a decade of rapid progress, research on Dirac materials and topological insulators remains exceptionally active and broad, with ongoing work ranging from exotic field theory to applied physics. At the interface between theory and experiment, there is an intense interest to understand the effect of non-electronic environments on the band topology of Dirac materials.
Recent research...

We study the exactly solvable dimerized antiferromagnetic spin-1/2 XY chain which exhibits quantum phase transitions. We analyze the phase diagram of the model and order parameters in various regions of the parametric space. We utilize the spin duality transformations and standard results of exactly solvable spin chains to analytically calculate the conventional Landau long-range order...

The dynamic response of magnetic media on long time scales is governed by the thermally activated reversal of uniformly magnetized nano-meter grains. Such processes are controlled by ‘rare events.’ Accurately modelling rare event presents a challenge as conventional micromagnetic techniques are limited to time scales on the order of micro-seconds. One approach that can be applied to simulate...

The synthesis of Dilute magnetic semiconductors (DMS) has attracted great interest
because of the potential application of these materials in spintronics. DMS can be
fabricated by alloying semiconductors with magnetic transition metal elements (TM),
such as Mn. However, the concentration of TM needed to realize the ferromagnetic order
in a semiconductor is still hard to achieve because of...

NbSe3 undergoes two charge-density wave (CDW) transitions with incommensurate (IC) modes q1 = (0,0.241,0) (at T1=144K) and q2 = (0.5,0.260,0.5) (at T2=59K). There is sufficient experimental evidence [1,2] that the two modes appear pair-wise along one (at T1) or along two (at T2) symmetry-related pairs of trigonal prismatic (TP) columns, which form together with the third, unmodulated pair, the...
