Gapless color superconductivity
… in the case of quark matter is called Color Superconductivity. Color superconducting matter must be electrically and color neutral, because otherwise there are huge energy costs, due to the charges. At asymptotically high densities, equal numbers of up, down, and strange quarks make the …

Nonreciprocal phenomena in superconductivity
… first example that we discuss is nonreciprocal superconductivity, which occurs upon simultaneous breaking of inversion and time-reversal symmetries. Nonreciprocal superconductors describe certain classes of unconventional superconductors that include certain kinds of mixed-pairing and …

High Pressure Studies of Superconductivity
<p>Superconductivity has been studied extensively since it was first discovered over 100 years ago. High pressure studies, in particular, have been vital in furthering our understanding of the superconducting state. Pressure allows researchers to enhance the properties of existing superconductors, …

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 …

Topics in theory of superconductivity
… parts on three different topics in theory of superconductivity. In the first part a theory of nonlocal electrodynamics of unconventional superconductors is developed and applied to calculate the magnetic penetration depth in the Meissner state for a simple d-wave model of the cuprate high …

Unconventional Superconductivity in Uranium Ditelluride
Superconductivity remains one of the most important topics in condensed matter physics, arising from the pairing of two fermions, in either a singlet or triplet spin configurations. Spin-triplet superconductivity has attracted a lot of interest due to its intriguing physics and potential …

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 …

Feasibility of superconductivity in semiconductor superlatices
The objective of this thesis is to explore superconductivity in semiconductor superlattices of alternating hole and electron layers. The feasibility of superconductivity in semiconductor superlattices is based on a model formulated by Harshrnan and Mills. In this model, a semiconductor superlattice …

MATRIX FIELD THEORY: APPLICATIONS TO SUPERCONDUCTIVITY
In this thesis a systematic, functional matrix field theory is developed to describe both clean and disordered s-wave and d-wave superconductors and the quantum phase transitions associated with them. The thesis can be divided into three parts. The first part includes chapters 1 to 3. In chapter …

Two key questions about color superconductivity
We pose two key questions about color superconductivity: What are the effects of the large strange quark mass, and what are the observable consequences of color superconductivity? Motivated by the first question, we study crystalline color superconductivity. We adapt the Nambu-Gor'kov formalism to …
