A Theory for Market Impact: How Order Flow Affects Stock Price
… the size of the order, but there exists little quantitative theory that suggests why this is so. I develop a quantitative theory for the market impact of hidden orders (orders that reflect the true intention of buying and selling) that matches the empirically measured result and that reproduces …

Essays on Labor Market Frictions and Institutions
… business cycle. The second chapter proposes a quantitative theory featuring time-consistent policy to rationalize the increased generosity of UI benefit duration during recessions. The final chapter explores the link between allowing unemployed workers to keep uncollected UI benefits and future …

Theory of High Temperature Spin Dynamics
… spins-both classical and quantum-and develop the quantitative theory of the time-dependent correlation functions characterizing the high temperature spin dynamics. The original results presented in this thesis include: (I) model-independent analysis of the long-time behavior of the correlation …

Spectral Properties of the Renormalization Group
… success which has been achieved in developing a quantitative theory of phase transitions. This work investigates various spectral properties of the RG map for Ising-type classical lattice systems. It consists of four parts. The first part carries out some explicit calculations of the spectrum of …

High Energy Laser Driven Electron Acceleration
… density gradients, in order to develop a fully quantitative theory of the laser-gas interaction.

Statistical Modeling of Wave Chaotic Transport and Tunneling
… the classical orbits are chaotic. We de- velop a quantitative theory for the statistics of energy level splittings for symmetric chaotic wells separated by a tunneling barrier. Our theory is based on the ran- dom plane wave hypothesis. While the fluctuation statistics are very different for …

The investigation of interactions between single walled carbon nanotubes and flexible chain molecules
… of the polymer. There is currently no quantitative theory capable of linking chemical structure to colloidal dispersion for nanorod systems. The goal of this thesis is to develop the first such model and to verify it experimentally. Applications to DNA oligonucleotide detection and …

Beyond Functionalism: A Quantitative Survey and Semiotic Reading of Hadrian's Wall
… of techniques including historiography, theory, quantitative survey and modelling. A theoretical standpoint is adopted that considers the construction from a symbolic perspective as an explicit means for understanding the original purpose of the Wall. Quantitative survey is used to reveal …

Geometry and Topology of Quantum States in Quasicrystalline Systems
… how geometrical and topological ideas from band theory can be extended to quasicrystalline systems. We start by studying a model of a shallow quasicrystalline optical lattice. Here we show that due to a natural hierarchy in the spectrum, an external force can be chosen such that the resulting …

Statistical physics of biological self-organization : case studies in protein folding and adaptation to time-varying fields
… the methods of statistical physics to provide quantitative insights into the behavior of biological systems. In the first half of the thesis, we use equilibrium statistical physics to develop a phenomenological model of how the hydrophobic effect impacts the structure of proteins, and in the …

Application of Lie symmetries to Solving Partial Differential Equations associated with the Mathematics of Finance
… Due to their work a rich arsenal of methods of theory of partial differential equations were suddenly available for mathematicians working in the area of mathematical finance. Adopting their approach of deducing prices of contingent claim via solving the associated PDE models, we apply the …

Studies in the theory of solids
… method was used on both the ·data and a theory which includes multiple scattering to confine the comparison to just the slowly varying surface dependent features. Chapter II: We show that energies of deep traps associated with impurities in semiconductors are controlled by the Sand P …

Opportunity identification in MNC subsidiaries: context and performance implications
… mixed methods approach in combining qualitative theory building and quantitative theory testing within a two-staged research methodology. The first stage involved conducting exploratory case studies in 6 Scottish “entrepreneurial” subsidiaries, given the scarcity of relevant empirical work. The …

Evolutionary trade-offs and adaptive phenotypic plasticity under multidimensional selective pressure
… phenotypes respond to selective pressure via a quantitative theory of evolution remains challenging due to a number of factors complicating the genotype to phenotype map. Genetic architecture presents an internal source of complexity, constraining adaptive responses by imposing trade-offs …

Generation of sand ripples and sand bars by surface waves
… of wave response. In Chapter 3, we develop a quantitative theory to describe the formation mechanism of sand bars by coupling sediment dynamics and wave hydrodynamics. Assuming that the slopes of waves and bars are comparably gentle and sediment motion is dominated by the bedload, an …

Interaction of Terahertz Radiation with Semiconductor Nanostructures and Quantum Systems
… exact origin was unknown, since a comprehensive theory describing propagation after the end of cylindrical waveguides was lacking in literature. To explain the observed mode profiles, I developed a ray-optical theory of cylindrical multimode waveguides, described in chapter 3. It predicts the …
