Imaging topological superconductivity in UTe_2
Superconductivity has been a topic of significant interest to the physics community for over a century. However, despite persistent effort, there remain many unsolved problems and unmeasured phenomena. Although the physics of p-wave superconductivity was developed in the 1960s there have been …

Self-Consistent Study of Topological Superconductivity in Two-Dimensional Quasicrystals
… and experimental activities in the field of topological superconductors. Topological superconductivity (TSC) results in a novel superconducting state characterized by a nonzero topological invariant in the bulk. There is a relation between the bulk and edges or surfaces, which is called the …

SPIN AND CHARGE TRANSPORT IN 2D MATERIALS AND VAN DER WAALS HETEROSTRUCTURES
This thesis focuses on the exploration of topological superconductivity in 2D materials and van der Waals heterostructures. Our approach is to realize topological superconductivity in Ising superconductors. A survey of different candidate materials systems for topological superconductivity is …

Exotic superconductivity in quantum materials
The theory of superconductivity developed by Bardeen, Cooper, and Schrieffer has proven to correctly describe a wide class of metals, where the effective attraction between electrons is mediated by phonons. Despite huge success, this theory fails to explain certain types of superconductivity, which …

Majorana-based Topological Quantum Algorithms in Magnet-Superconductor Hybrid Structures
Majorana zero modes harbored by topological superconductors may be the key ingredient for the realization of fault-tolerant quantum computing and topologically protected quantum devices. Magnet-superconductor hybrid (MSH) systems have proven to be an experimentally versatile platform for quantum …

The Death of Quasiparticles: Strongly Interacting Gapless Phases with Fermi Surfaces and Fractional Statistics
… and superconductors to exotic insulators with topological order. In this thesis, I describe my research in gapless quantum phases in which the framework of quasiparticles breaks down. The main characters are two categories of gapless phases that feature the interplay between strong interactions …

Rotational Symmetry and Phase Dynamics in Topological Superconductors
Topological superconductors are phases of matter that cannot be adiabatically connected to a trivial superconductor without closing the bulk gap or breaking some fundamental symmetry. Intimately tied to topological superconductors are Majorana bound states. These are neutral zero-energy …

Topological insulators and semimetals in the presence of interactions
Topological insulators and semimetals possess the exotic gapless excitations that are governed by relativistic quantum mechanics. Due to the growing interests in these phases, the number of the materials predicted and shown to have the topological characters are continuously increasing. …

Interfacial Properties of Graphene for (Opto)Electronic Devices
… This may lead to the observation of chiral topological superconductivity in SLG. The final application I studied is using SiO<sub>2</sub> as a solid electrolyte to realize electrical double-layer gated solid state SLG and MoS<sub>2</sub> transistors. I have achieved arrays of SLG and …

Angle-resolved photoemission studies of topological thin films and superconducting heterostructures
In recent years, topological phases of matter have remained at the forefront of condensed-matter physics research due to the presence of unusually robust, conducting boundary states in these systems. Their unique bulk electronic band structures in tandem with these topologically protected states …
