Seo, Dongmin (2009-05-15)This dissertation focuses on three separate studies. First, magnetization of the Mn12- acetate was studied by low temperature hysteresis loops and DC magnetization data on magnetically aligned Mn12-acetate micro-crystals. ...

Agarwal, Lakshya (2023-05-15)The study of quantum many body physics occupies a special place in the landscape of theoretical science, as it behaves like a connective tissue between seemingly disparate domains of inquiry, such as computer science, ...

Corbin, James Edward (2019-10-22)We consider a compact C ∞-stratified 2D variety M in R^3 and its ε-neighborhood Mvε , which we call a “fattened open book structure.” Assuming absence of zero-dimensional strata, i.e. “corners,” we show that the (discrete) ...
-
Liu, Yang (2012-10-19)We study current-induced domain wall dynamics in a thin ferromagnetic nanowire. We derive the effective equations of domain wall motion, which depend on the wire geometry and material parameters. We describe the procedure ...
-
Kellams, Joshua Norman (2018-11-20)The current development technique for Bi-2212 multifilament superconducting wire is the oxide powder in tube process. For this process, phase pure Bi-2212 fine powder is loaded into a silver tube then drawn, stacked, and ...

Gayles, Jacob Davis (2016-12-16)In this dissertation I will discuss the effect of real, momentum, and mixed space Berry phases in B20 compounds: MnSi, Mn1-xFexGe, and Fe1-yCoyGe. Recently there has been a tremendous experimental effort in stabilizing ...
-
Means, Joel Lewis (2009-05-15)Interactions between Mn12–acetate molecular magnets and thin gold films have been explored in light of the theory of weak localization. Low-temperature measurements of the magnetoresistance of gold films of varying ...
-
Sun, Deqiang (2010-01-16)This dissertation discusses the Landau-Zener (LZ) theory and its application in noisy environments and in many-body systems. The first project considers the effect of fast quantum noise on LZ transitions. There are two ...
-
Lan, Ruomeng (2019-10-25)We study the spectral stability of the solitary wave solutions to the nonlinear Dirac equations. We focus on two types of nonlinearity: the Soler type and the Coulomb type. For the Soler model, we apply the Evans function ...
-
Tikhonov, Konstantin S (2015-12-21)In this dissertation, the results obtained during my PhD work are presented. As an introduction, the brief review of the theory of superconducting fluctuations and a short discussion of experimental situation in the field ...
-
Chen, Qianfan (2021-05-26)In recent years condensed matter physics is witnessing a rapid expansion of materials with (massless) Dirac fermions as low-energy excitations, with examples ranging from graphene, topological insulators to Weyl semimetals ...
-
Long, Zhongqu (2019-04-04)Nanostructured materials and topological materials have many unique and fascinating electronic and optical properties. In this dissertation, we explore the optics in those new materials from three aspects: 1. Optical ...
-
Wrobel, Konrad (2021-04-26)Orbit equivalence is an equivalence relation on measurable actions of groups that’s been studied since the 1950’s. It has connections to many areas of mathematics including descriptive set theory, percolation theory, ergodic ...
-
Do, Ngoc Thanh (2016-05-31)In this dissertation we deal with some spectral problems for periodic differential operators originating from mathematical physics. We begin by using quantum graphs to model a particular graphyne and related nanotubes. The ...
-
Liu, Xin (2012-10-19)We study the spin dynamics in a high-mobility two dimensional electron gas (2DEG) system with generic spin-orbit interactions (SOIs). We derive a set of spin dynamic equations which capture the purely exponential to the ...
-
Liu, Xiongjun (2012-10-19)The Hall resistivity in ferromagnetic materials has an anomalous contribution proportional to the magnetization, which is defined as the anomalous Hall effect (AHE). Being a central topic in the study of ferromagnetic ...
-
Cernov, Cristian (2021-05-26)In this thesis, I propose practical ways to incorporate tin-based polymers, cyclic tin rings, and tin-substitution diamonds into microscale electronic devices. Using spin-polarized, noncollinear magnetization, and spin-orbit ...
-
Rohe Salomon Da Rosa Rodrigues, Davi (2018-05-22)In this thesis we propose a novel method to study the dynamics of topological magnetic textures. Based on the stability of these objects, scaling and symmetry arguments, we show that, despite the complexity of the micromagnetic ...
-
Amin, Vivek Pravin (2014-04-18)Due to their ubiquitous presence in hard-disk drives and growing potential as commercially viable memory bits, Magnetic Tunnel Junctions (MTJs) continue to provide impetus for scientific study. The demand for smaller devices ...
