Results are reported of small-angle neutron scattering studies of the collective vortex behaviour from two overdoped YBa2Cu3O7-d samples, one 90% detwinned and one twin free. The results are discussed alongside other studies of similar samples over the years of SANS studies of t…

The MINOS experiment was designed to measure neutrino oscillation parameters with muon neutrinos. It achieves this by measuring the neutrino energy spectrum and flavour composition of the man-made NuMI neutrino beam 1km after the beam is formed and again after 735 km. By compari…
Quantum electrodynamics in free-space is a well-understood and a very successful theory. This is not the case when polarizable boundaries are present, which is a common scenario. The presence of reflective surfaces affects the photon field. Thereby the quantummechanical vacuum f…
The way motion is generated and controlled in robotics has traditionally been based on a philosophy of rigidity, where movements are tightly controlled and external influences are ironed out. More recent research into autonomous robots, biological actuation and human machine int…
These are privileged times to be a cosmologist. Recent years have witnessed unprecedented progress in observational and computational techniques and we now are able to quantify cosmological properties with unprecedented accuracy. My work builds upon this observational accuracy b…
Object recognition is arguably one of the main tasks carried out by the visual cortex. This task has been studied for decades and is one of the main topics being investigated in the computer vision field. While vertebrates perform this task with exceptional reliability and in ve…
We investigate generalizations of coherent states as a means of representing the dynamics of excitations of the superconducting ground state. We also analyse the propagation of generalized coherent state wave packets under the Bogoliubov-de Gennes Hamiltonian. The excitations of…
Paired kitchen-living room dust samples from 30 UK houses were collected for the analysis of BFRs, including PBDEs, HBCDDs and PBEB, EH-TBB, BTBPE, BEH-TEBP, DBDPE. Ninety-six plastic kitchen utensils were collected, screened for Br concentration by X-ray fluorescence spectromet…
This study explores the mediatisation of political challenges involved in addressing climate change, in particular relation to the United Nations framework in place to tackle the issue. Climate change is one of the most urgent issues of our time and extensive international colla…
This is a thesis in two parts. In Part I, we will study the shear response of confined vortices. In Part 2, we will study light and matter interactions in photonic crystal fibres. Whilst the approaches of each are completely different, they both have the same central theme: soli…
The anomalous Doppler instability (ADI) is a key relaxation mechanism for suprathermal electrons in magnetic confinement fusion (MCF) plasmas. The ADI involves a shift from parallel to perpendicular electron motion, accompanied by the excitation of waves at frequency and wavenum…
The ability to control the magnetic properties of low-dimensional magnetic systems is a major aim of research in condensed matter physics. Bespoke magnetic systems have potential uses in many practical applications and experimental investigations of theoretical predictions. To a…
Statistical Mechanics (SM) is a branch of theoretical physics which inquires the properties of systems made up of a large number of interacting components. Starting from the details of the dynamics describing the interaction among the smaller components, the goal of statistical …
Developing a Grid within High Energy Physics for the Large Hadron Collider particle accelerator is characterised as a highly collaborative, distributed and dynamic systems development effort. This research examines the way this distributed Grid is developed, deployed and provide…
The mixed alkali borosilicate glass system used for high-level waste immobilisation, has been studied with different divalent additive oxides such as CaO, Srf), BaO, MnO, ZnO and PbO added to the BNFL base glass (MW). A number of techniques have been employed in order to study t…
Spectral-domain optical coherence tomography (SD-OCT) is a type of non-destructive imaging technique that is capable of resolving the inner structure of a sample with micrometre spatial resolution. SD-OCT is based on low coherence interferometry. It utilises a spectrometer to gr…
In early 2021 both NASA's Mars 2020 and ESA's Rosalind Franklin rovers will land on Mars carrying Raman spectrometers. This will be the first time that a Raman spectrometer has been deployed on another planetary body and both rovers will conduct their mission in regions that con…
The progressive improvement in the operating performance of existing nuclear reactors has brightened the outlook for nuclear power around the globe. In order to use less carbon based power, the use of nuclear reactors provides an attractive solution. However, questions are raise…
Between 2015 and 2018, proton-proton collisions were performed at the highest energy ever achieved in man-made particle accelerators, with the Large Hadron Collider at CERN. This thesis presents measurements performed with the ATLAS detector which fully exploit this energy, of t…
