Some properties of the magnetic response of mesoscopic superconducting rings
… we focus our attention on the topic of the half- quantum vortex. Such an object can exist in systems with spin triplet pairing in which the equal-spin-pairing state is realized. This state is found in the A-phase of 3 He and is currently believed to describe superconductivity of a strongly …

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 …

Geometry and topological phase of matter
… effective field theories of isotropic-nematic quantum phase transitions of Quantum states. The low-energy theory of the nematic field has z=2 dynamics due to a Berry phase of the order parameter, which is related to the Hall viscosity in parity and time-reversal-symmetry (TRS) broken states. …

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 …
