Kaluza-Klein Theories, Branes and Cosmology
… between the two points of view. We discuss chiral fermion modes which are determined by the structure of the singularities. In order to approach the Cosmological Constant Problem and the related dark energy discussion in this context, we study the cosmology of a toy model, six-dimensional …

Arithmetical, geometrical, and categorical forays into particle physics
… of the Standard Model gauge algebra when the chiral fermion content is that of the Standard Model plus three singlets, is found for the first time. For the same Standard Model set up, a computational approach is used to catalogue all semisimple extensions. The second foray studies quantum …

Aspects of symmetry, topology and anomalies in quantum matter
… lattice model regularizing the low-energy chiral fermion/gauge theory towards the Standard Model while overcoming the Nielsen-Ninomiya fermion-doubling problem without relying on Ginsparg-Wilson fermions. We conclude by utilizing aspects of both quantum mechanical topology and spacetime …

Dynamics of Chiral Fermions
… quantum field theories containing Weyl fermions respecting some chiral symmetry. There are severe challenges in lattice regularising such theories and chiral gauge theories, where a non-anomolous chiral symmetry is gauged, can display interesting strong coupling dynamics such as …
