Interrogation and refinement of DFT+U+J energetics in magnetic systems
(Trinity College Dublin. School of Physics. Discipline of Physics, Trinity College Dublin, School of Physics, 2025)With quantum computing just beyond the horizon, more emphasis than ever in history is placed on adaptable, efficient, yet accurate algorithms for routinely modeling properties of large-scale material systems. Among those ... -
Experimental investigation of polarization rotation in semiconductor optical amplifiers
(2004)In this paper we present an experimental study of polarisation rotation in a semiconductor optical amplifier. We use two techniques to investigate the gain and birefringence along the two eigen modes of the component ... -
Production and processing of graphene and related materials
(2020)We present an overview of the main techniques for production and processing of graphene and related materials (GRMs), as well as the key characterization procedures. We adopt a 'hands-on' approach, providing practical ... -
Above the Clouds: Probing the atmospheres of ultra-hot Jupiters at high-resolution
(Trinity College Dublin. School of Physics. Discipline of Physics, School of Physics, 2025)One of the most surprising discoveries of the numerous exoplanet surveys conducted over the past two decades is the existence of close-in giant planets orbiting their host stars at orbital separations smaller than that of ... -
Two-Dimensional Materials for Tissue Engineering and Neural Interfacing Applications
(Trinity College Dublin. School of Physics. Discipline of Physics, Trinity College Dublin, School of Physics, 2025)The pages of a book behave very strangely compared to a block of wood - two-dimensional (2D) nanomaterials are no different. Offering unique properties that differ from their bulk counterparts, this simple change in ... -
Growth and characterisation of sustainable transparent conducting oxides
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)In this thesis the growth and optoelectronic properties of the ternary n-type amorphous zinc tin oxide (a-ZTO) and p-type crystalline V2O3 are discussed in the context of providing suitable and sustainable candidates for ... -
Searching for late-time interaction between Type Ia supernovae and distant circumstellar material using the Zwicky Transient Facility
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)The nature of the progenitor systems and explosion mechanisms that give rise to Type Ia supernovae (SNe Ia) is still debated. In rare cases the ejecta interact with circumstellar material (CSM) that was ejected from the ... -
Characterising the Hierarchy of Multi-time Quantum Processes with Classical Memory
(2024)Memory is the fundamental form of temporal complexity: when present but uncontrollable, it manifests as non-Markovian noise; conversely, if controllable, memory can be a powerful resource for information processing. ... -
Characterising transformations between quantum objects, `completeness' of quantum properties, and transformations without a fixed causal order
(2024)Many fundamental and key objects in quantum mechanics are linear mappings between particular affine/linear spaces. This structure includes basic quantum elements such as states, measurements, channels, instruments, ... -
Overcoming temperature limitations in laser cooling using dressed states and diamond vacancies
(SPIE, 2025)The established approach to laser cooling of solids relies on anti-Stokes fluorescence, for example from rare earth impurities in glass. Although successful, there is a minimum temperature to which such a process can cool ... -
Exact Conditions in Density Functional Theory and their application to Hubbard type Corrective Functionals
(Trinity College Dublin. School of Physics. Discipline of Physics, Trinity College Dublin, School of Physics, 2025)The work of this thesis falls within the topic of Kohn Sham (KS) and Generalised Kohn Sham (GKS) theory, the practical implementation of which are the most popular tools for predicting the electronic properties of atoms, ... -
Morphological & Electrical Characterisation of Nanosheet Networks
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Since the discovery of the stability and excellent electrical properties of the graphene monolayer, there has been a great deal of excitement about the superlative electrical, mechanical and thermal properties of 2D ... -
Thermodynamics of Nanoelectromechanics
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Taking inspiration from nanoelectromechanical experiments, we introduce a microscopic toy model consisting of a resonant-level quantum dot coupled to two electrodes and a single-mode oscillator. We derive a Fokker-Planck ... -
