Detection of the Faraday Chiral Anisotropy
(2021)
Being the intimate connection between chirality and magnetism, magneto-chiral anisotropies (MChA) - featuring non-reciprocal optical responses in chiral systems depending on the relative direction of the magnetic field B ...
Multipartite entanglement in the Eigenstate Thermalisation Hypothesis
(2020)
We study the quantum Fisher information (QFI) and, thus, the multipartite entanglement structure of thermal pure states in the context of the eigenstate thermalization hypothesis (ETH). In both the canonical ensemble and ...
Polaronic distortion and vacancy-induced magnetism in MgO
(2010)
The electronic structure of the neutral and singly charged Mg vacancy in MgO is investigated using density
functional theory. For both defects, semilocal exchange correlation functionals such as the local spin ...
The structures and extents of the chromospheres of late-type stars
(Trinity College (Dublin, Ireland). School of Physics, 2015)
The chromosphere is the region of a star, above what is traditionally defined as the stellar surface, from which photons freely escape. As the definition implies, this region is characterised by complexity, non-equilibrium, ...
The effects of fatty deposits on the accuracy of the Fibroscan? liver transient elastography ultrasound system
(Institute of Physics, 2012)
A new generation of ultrasound transient elastography (TE) systems have emerged which exploit the well-known correlation between the liver?s pathological and mechanical properties through measurements of the Young?s elastic ...
Heat capacity and metal-insulator transition in Ti4O7 single crystals'
(American Physical Society, 1974)
Heat-capacity and entropy changes at the metal-insulator transitions have been measured on Ti4O7 single crystals. The 130-K transition is related to a disordering of the Ti3+ and Ti4+ chains at the unit cell level. Ti3+ ...
New materials for spin electronics
(Trinity College (Dublin, Ireland). School of Physics, 2015)
Magnetic components are currently widely used in electronic devices, especially in the field of data storage. The need for downscaling the lateral dimensions of every component following Moore's law brings new challenges ...
Atomistic simulations of spin-dynamics
(Trinity College (Dublin, Ireland). School of Physics, 2009)
Current-induced spin-transfer torque effects form an exciting branch in the field of spintronics with a huge potential for applications. Magnetization dynamics phenomena like switching or GHz frequency precession in spin ...
Towards data-driven magnetic materials discovery
(Trinity College Dublin. School of Physics. Discipline of Physics, 2017)
Magnetic materials underpin many of the technologies that define the world we live in. Despite the tremendous technological progress, the discovery of new magnetic materials has been rather slow. In this Thesis we explore ...
