On the Role of Projectile Electrons in an Independent Electron Model Description of Dressed-Ion Impact on Atoms
The presence of electrons on ions which collide with neutral atoms constitutes a challenge to theoretical descriptions of the collision dynamics. These collisions pose quantum-mechanical many-body problems that cannot be ...
Modified Gravity and Cosmology on the Largest Scales
This dissertation presents a series of my contributions to research in theoretical cosmology, focusing on aspects of the very large scale universe, particularly dark energy, cosmic acceleration, modified gravity, and cosmic ...
Topological Dynamical Systems Methods in Early-Universe Cosmologies
This dissertation describes some important problems that we have tried to solve with respect to the state of the early universe, that is, the universe shortly after the Big Bang. Standard early-universe cosmological ...
The Strong Isospin-Breaking Correction to the Leading-Order Hadronic Vacuum Polarisation Contribution to the Anomalous Magnetic Moment of the Muon
The contribution of strong isospin-breaking (SIB) effects to the value of the anomalous magnetic moment of the muon is studied using the leading-order SIB component of the photon vacuum polarisation function, calculated ...
