Local field effects on the dielectric properties of solids have
been studied for three-dimensional and two-dimensional crystals by
using two kinds of dipole models: an atomic dipole model in which
dipoles coincide with atom sites and a bond dipole model in which
dipoles are placed along bond directions. Local fields...
The extended-Lifshitz-Kosevitch formalism (ELK) unifies the treatment of
the de Haas-van Alphen (dHvA) effect, allowing it to transcend its traditional roles
of mapping Fermi surfaces and measuring effective masses. Here we exploit the
capabilities of dHvA as a probe of many-body effects to examine heavy-fermion su-
perconductivity. ELK successfully describes...
Collective excitation(plasmon) modes of an electron
gas in a multilayer system (superlattice) have been studied
in great detail in recent years. One important aspect
of this Fermion system is that the dispersion relation of
the plasma frequency shows transitional behavior between
two- and three- dimensional character. Inelastic light
scattering experiment...
In this work we apply the finite temperature formulation of quantum
statistical mechanics to an analysis of the de Haas-van Alphen effect
in the quantum limit. A new expression is derived for the differential
magnetic susceptibility which clearly shows the individual contributions
of zero-temperature and non-zero temperature terms.
Interactions have...
The objective of this dissertation is to examine federally administered soil conservation policy within the United States and the broadly defined Columbia River Basin in the US Northwest. I accomplish this in five chapters. In the first chapter I provide background information for the study. In the second chapter I...
This study investigates nonlinear optical properties
of matter. Nonlinear optical effects have found a wide
field of applications such as the extension of the
operation range of lasers to higher frequencies, material
probes and optical image processing.
A brief introduction to the most common nonlinear
optical phenomena is given and...
This thesis explores some of the ethical issues pertaining to the use of so-called radical enhancement technology. Key concepts analyzed include “normal function”, “human being”, and “personhood.” I argue that the use of these key concepts in the debate thus far has lacked philosophical rigor, and that a reexamination of...
This thesis analyzes the emerging technology of hydraulic fracturing and shale gas extraction process through a pluralistic philosophical approach. Rather than defending traditional values in nature, such as intrinsic value, I defend a metaphilosophical pragmatism centered on policy implications. I argue that different philosophical positions will, most of the time,...
Hume’s division of truth into agreement with matters of fact or relations of ideas casts doubt on our capacity to have moral knowledge, as moral propositions do not seem to fall obviously into either category. This thesis looks at how two views, ‘descriptive moral functionalism’ and ‘moral concept essentialism’, try...
In this thesis, in order to understand why Buddhists in Southeast Asia protect rainforests and to establish a solid foundation for Buddhist environmental ethic, my first two tasks are to draw a clear picture regarding two major environmental concepts--nature and anthropocentrism--in Buddhism and to defend the claims that the Buddhist...
