Explorations of domain walls and half quantum vortices in unconventional superconductors
… superconductors have been proposed to host half quantum vortices, whereas superconductors with spontaneously broken time-reversal symmetry are proposed to admit domain walls that separate regions of opposing chirality. Thus--in addition to conventional vortices--the topological structure of …

Numerical study of p-wave superconductivity in Sr2RuO4
… angular momentum state allows the formation of half-quantum vortices possessing half of the usual flux quantum. In Chapter 1, I briefly review p-wave superconductivity and see how it supports half-quantum vortices. In Chapter 2, I review the conventional Ginzburg- Landau formalism for treating …

Investigation of half-quantized fluxoid states in Sr2RuO4 mesoscopic superconducting rings
… exotic objects, such as chiral edge currents and half-quantum vortices (HQVs) characterized by the nontrivial winding of the spin structure. In this dissertation, we present cantilever magnetometry measurements performed on mesoscopic samples of Sr2RuO4, a spin-triplet superconductor. Satisfying …

Exotic vortices in superfluids and matrix product states for quantum optimization and machine learning
The interest in vortices and vortex lattices was sparked by the prediction of quantisation of circulation by Onsager in the 1940s. The field has since developed dramatically and attracted a lot of interest across the physics community. In this dissertation we study vortices in two different …
