Three Dimensional Pseudospectral Self -Consistent Field Approximation
For the eigenvalue problem, a novel variant of Davidson's method, or spectrally localized Arnoldi's method, is used. The full-size problem is projected onto Krylov subspaces of limited size with an explicitly orthogonalized basis. The smaller-size projected problem is solved using LAPACK library …

Self-consistent Monte Carlo simulations of plasma processing reactors
… collisions must be considered. In this thesis, a self-consistent Monte Carlo (MC) simulation for low-temperature partially ionized plasmas is presented. In this simulation, the effects of electron-electron collisions are taken into account. Electron-electron collisions are treated as being …

Self-Consistent Study of Topological Superconductivity in Two-Dimensional Quasicrystals
… QCs are inherently fractal, and characterized by self-similarity. It is interesting to ask whether a stable TSC phase can exist in QCs, despite their aperiodic and fractal structure. In this thesis, we solve the Bogoliubov-de Gennes (BdG) equations — coupled Schrödinger-like equations for the …

The solar tachocline: a self-consistent model of magnetic confinement
In this dissertation we consider the dynamics of the solar interior, with particular focus on angular momentum balance and magnetic field confinement within the tachocline. In Part I we review current knowledge of the Sun's rotation. We summarise the main mechanisms by which angular momentum is …

On Symmetry of Multiple Self-Consistent-Field Hartree–Fock Solutions
… equations necessitates the existence of multiple self-consistent-field (SCF) solutions. This is especially true for systems containing unpaired electrons, or electrons with high angular momenta, or both, in which many low-lying HF solutions can be located. However, there has not been much …

Self consistent bathymetric mapping from robotic vehicles in the deep ocean
… This thesis presents a methodology to produce self-consistent maps and simultaneously improve vehicle position estimation by exploiting accurate local navigation and utilizing terrain relative measurements. It is common for errors in the vehicle position estimate to far exceed the errors …

Field theories for copolymer blends : self-consistent approaches and Monte Carlo simulations
In der vorliegenden Arbeit wird auf der Basis der selbstkonsistenten Feldtheorie (SCFT) für Polymermischungen eine neue Simulationsmethode eingeführt, die mittels eines Monte-Carlo-Algorithmus die Berücksichtigung von thermischen Fluktuationen erlaubt. Diese Methode wird auf das ternäre System aus …

Building galaxy models with self-consistent prescriptions for stellar and nebular emission
… galaxy models. I have integrated a fully self-consistent treatment of nebular line and continuum emission into the SPS code Flexible Stellar Population Synthesis (FSPS; Conroy et al. 2009), using the photoionization code CLOUDY (Ferland et al. 2013). This model, CloudyFSPS, successfully …

A quasi-dynamic and self-consistent rupture model to simulate earthquake ruptures
Dynamic earthquake rupture modeling provides information on the rupture physics as the rupture velocity, frictions or tractions acting during the rupture process. Nevertheless, as often based on spatial gridded preset geometries, dynamic modeling is depending on many free parameters leading to both …

Self-consistent dynamical and radiative models of low-luminosity active galactic nuclei
… numerical techniques we have developed to build self-consistent dynamical and radiative models of LLAGN and their application to modeling the galactic center source Sgr A*. Sgr A* is an extremely low luminosity LLAGN and is a particularly attractive target for modeling black hole accretion flows …

False memory production: effects of self-consistent false information and motivated cognition
… received intense public scrutiny. Based upon self-schema (Markus, 1977) and self-verification (Swann, 1987) theories, two studies were conducted to investigate the hypothesis that a self-schema guides cognitive processing of self-relevant information and thereby influences the construction of …

Electrostatic Trapping as a Self-Consistent Phenomenon in Plasmas and other Collective Systems
This thesis investigates self-consistent electrostatic structures in plasmas and related collective systems. They are coherent structures in which particles become trapped in the wave potential. These phenomena require a kinetic description i.e. a description in which the velocity distribution of …

Self-assembly of Block Polymers: Self-Consistent Field Theory and Monte-Carlo Simulations
Block polymers are a class of soft materials that self-assemble at mesoscopic length scales to form a wide variety of ordered structures. The resulting nanostructures have been instrumental in the development of several advanced technologies such as separation membranes and photonic crystals. This …
