The Two Wells System: A Benchmark for Monte Carlo Methods in Statistical Mechanics

Creator:: Sprueill, Henry
Abstract:: Computational statistical mechanics leans heavily on the class of Markov Chain Monte Carlo Algorithms. Many such algorithms exist, and simulations can run for several weeks, making the selection of algorithms a difficult, but critical task. In this work, we introduce a benchmark system of two quadratic wells with an analytical...

Simulating the Dynein Motor Protein: A Monte Carlo Approach to Achieve Coordinated Stepping

Creator:: Kiatvongcharoen, Jin
Abstract:: The motor protein dynein is responsible for cellular processes such as axonal transport and cell division by delivering vital information along the microtubule track. A failed delivery can cause severe damage to the cell’s functionality and lead to neurological diseases. Despite dynein’s rich history in cellular research, the mechanism of...

Freezing a Softly Repulsive Fluid : Monte Carlo Methods and the Weeks-Chandler-Andersen Potential

Creator:: May, Christopher
Abstract:: The equation of state for a fluid described by the Weeks-Chandler-Andersen (WCA) potential was solved to determine at what pressures and temperatures the fluid will theoretically freeze. A Monte Carlo (MC) algorithm was used to sample a system of 256 spheres for a set of thermodynamic averages to locate and...

Theory of Inhomogeneous Fluids

Creator:: Krebs, Eric J.
Abstract:: This dissertation reports on the computational physics research in the area of inhomogeneous fluids. I first discuss the theory background for this work beginning with water, which is important for the two published articles that are presented in this work (Chapters 5 and 6). Next, I give a brief overview...

Hard spheres within classical density functional theory and Min proteins in Escherichia coli

Creator:: Schulte, Jeff B.
Abstract:: This thesis reports on computational research in two different areas. I first discuss the Min-protein system found within Escherichia coli. Following this I discuss an extended investigation into improving free energy functionals that are used within Classical Density Functional Theory in order to model water. Chapter 2 examines the dynamics...

X-ray study of an isobranched lecithin

Creator:: Herpe, Joachim
Abstract:: Lipids, especially phospholipids, are very common but important molecules found in cells and animal tissue, performing many biological functions, particularly in membranes. Lipids, when mixed with water, spontaneously form ordered systems, such as micelles, vesicles and multibilayers. The size of these systems and their degree of ordering depend on the...

Hypervelocity spectroscopy from impacts in polymeric materials

Creator:: Buettner, Douglas J.
Abstract:: Stacked sheets of polyethylene terephthalate andpolystyrene provide a means for recovering projectiles travelling at hypervelocities. The transparency of these multiple diaphragms is utilized so that light generated from hypervelocity impacts can be studied. A method for gathering visible as well as ultraviolet light from less transparent polymer foams has been...

The effect of void distribution on the Hugoniot state of porous media

Creator:: Creel, Emory Myron Willett
Abstract:: Shocked porous granular material experiences pressure dependent compaction. D. John Pastine introduced a model in which the degree of compaction is dependent on the pressure induced by the shock wave, the shear strength of the material, and the distribution of void sizes. In the past, the model could only be...

An Ising-like model to predict dielectric properties of the relaxor ferroelectric solid solution BaTiO3 - Bi(Zn1/2Ti1/2)O3, An Ising-like model to predict dielectric properties of the relaxor ferroelectric solid solution BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃

Creator:: Jackson, Dennis L.
Abstract:: We developed a model to investigate the dielectric properties of the BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃ (BT-BZT) solid solution, which is a relaxor ferroelectric and exhibits long range disorder. The model uses ab initio methods to determine all polarization states for every atomic configuration of 2 x 2 x 2 supercells of...
