Simulations of nanoscale spatial disorder
… testing of two simulations of nanometer scale disorder phenomena important for electronic device fabrication. We created a kinetic simulator for the surface assembly of quantum dots into ordered or disordered monolayers. We utilized a platform for high-precision motion and collision resolution …

Spatio-Temporal Patterns, Correlations, and Disorder in Evolutionary Game Theory
… to study emerging spatio-temporal patterns, spatial correlations, and the influence of quenched spatial disorder in rock-paper-scissors systems either with or without conserved total population number. In balanced rock-paper-scissors systems far away from the ``corner'' of configuration …

Controlling nanomaterial self-assembly for next generation optoelectronic applications
… ensemble of nanocrystals introduces energetic disorder and spatial disorder in films. While synthesized as a colloid, for most applications the nanocrystals are deposited as a thin film. The rate of energy transfer between nanocrystals in the film, dictated by the arrangement and distance …

Quantum phase transitions in disordered magnets
"We study the effects of quenched weak disorder on quantum phase transitions in disordered magnets. The presence of disorder in the system can lead to a variety of exotic phenomena, e.g., the smearing of transitions or quantum Griffiths singularities. Phase transitions are smeared if individual …

Analytical and numerical studies of photo-injected charge transport in molecularly-doped polymers
… analytical and numerical predictions of five disorder-based models, the Gaussian disorder model (GDM) of Bäassler, and four correlated disorder models introduced by Novikov, et al., and by Parris, et al. In these numerical studies, disorder parameters describing each model were varied from …

The geography of the clinic: spatial form, meaning and practice at a Western Cape community health centre
… understood as socially and political contingent. Spatial disorder and insecurity was demonstrated to impact directly upon clinical functioning and social identity. Current changes in health policy, service deterioration and community conflict have amplified staff's anxieties regarding real and …

Charge carrier dynamics in lead sulfide quantum dot solids
… quantum dot solids, the site-to-site energetic disorder that comes from size dispersity and the size-dependent band gap is very small and spatial disorder in the quantum dot superlattice often has a greater impact on charge transport. In Chapter 2, we show that improved structural order from …

Redefining learning environments in conflict areas : a Palestinian case study
… a broader learning environment, then the socio-spatial issues impacting student success may be improved. To test this hypothesis, learning environments in the OPT are examined with a two-fold methodology: historical and architectural. The two-fold analysis utilizes a conceptual framework, where …

Transport and thermodynamic studies of the superconductors A3T4Sn13 and YFe2Ge2
… transition could manifest as a structural disorder. We have measured thermal conductivity at temperatures much lower than $T_c$ and found that it is well described by a single power law with suppressed exponents near the QCP. The heat capacity, however, remains ~ $T^3$. After excluding …

3-D modeling of shallow-water carbonate systems : a scale-dependent approach based on quantitative outcrop studies
… distribution consisting of an arrangement of spatially independent lithofacies bodies along the depositional profile. The increase of spatial disorder from the basin to bedding scale results from the influence of autocyclic factors on the transport and deposition of carbonate sediments. …

Some Aspects of Fluctuation Driven Phenomena
… experiments. We investigate the influence of spatial disorder on coined quantum walks. Coined quantum walks describe the time evolution of a quantum particle that is controlled by a quantum coin degree of freedom. We consider one-dimensional walks and use a two- level system as quantum coin. …
