(Vanderbilt University. Department of Physics and Astronomy, 2014-04)Creating high-brightness electron beams, which have many practical applications, is done with cathodes in regions with large electric field by field emission. The brightness is high when the current is high and the ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)The study of living specimens is essential to the understanding of organismal behavior. Unfortunately, a major difficulty in the study of live organisms is that many move in and out of the field of view or focal plane ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)Finite element modeling was performed using COMSOL Multiphysics to study the thermal dynamics of gold::vanadium dioxide (VO$_{2}$) nanocomposites. These simulations were done to understand the data from transient ...

Influence of patient size on dose to female breast tissue during routine computed tomography scans (Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-21)Monte Carlo methods are well suited to the evaluation of radiation transport phenomena. The scalable phantoms employed in this project permitted rapid creation of three models of similar geometry, but different body habitus. ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2010-04)Enclosed microfluidic devices provide excellent systems for the study of biological processes such as cell-cell, paracrine, and autocrine signaling systems. By minimizing the fluid volume within the chambers, ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2019-04-18)In this thesis, we present LieART 2.0 which contains substantial extensions to the Mathematica application LieART (Lie Algebras and Representation Theory) for computations frequently encountered in Lie algebras and ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)A retarding mesh analyzer was used to measure the electron energy spectrum field emitted from a single tip of a Diamond Field Emitter Array. The emission was dominated by adsorbed gas atoms and molecules on the surface ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)Precise control of fluid delivery in analytical devices may be achieved by harnessing electroosmotic flow (EOF) in oxidized poly(dimethylsiloxane) microfluidic channels fabricated via soft lithography. However, the ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2010-04-27)Current models of nuclear structure describe nuclear states in terms of collective vibrations and rotations of a ground state. - One such quadrupole vibrational band is the gamma-band formed by vibrations of the short ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2016-05-02)A Fano resonance is an asymmetric, resonant scattering phenomenon which occurs in a multitude of fields, such as atomic physics, nuclear physics, nonlinear optics, and nanophotonics. The Fano resonance is a many-particle ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)I develop a perturbation theory for resonant frequency shifts caused by thin layer of material added to dielectric systems. This development can be used to effectively model photonic surface-sensing systems, which use ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2019)New massive spin-2 particles are predicted in theoretical extensions to the Standard Model (SM) attempting to solve the hierarchy problem. Such theories postulate that gravity is diluted compared to the other fundamental ...
-
(Vanderbilt University. Department of Physics and Astronomy, 2014-04)We examine models of quintessence in which a minimally-coupled scalar field phi evolves near a local extremum of its potential V ( phi) at phi_*. Assuming that (1/V )(dV/dphi) is small and w ~ -1, we Taylor expand the ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-05-04)Density functional theory is utilized in real-time, real-space simulations of LEED measurements and attosecond electron scattering. For LEED measurements, we find that our simulation results agree well with experimental ...
-
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-18)Confocal scanning laser microscopy and multiphoton microscopy provide 3D data from biological specimens, but with limited z-axis precision. Multiple microscale mirrors can be used to obtain more accurate 3D data on living ...
-
(Vanderbilt University. Deptartment of Physics and Astronomy, 2013-04-22)Chemical Exchange Saturation Transfer (CEST) is often overlooked as a method for the investigation of metabolites in vivo due to the time required to obtain a full spectrum. We investigated the feasibility and optimization ...
-
(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)Time Dependent Density Functional Theory is used to probe the structure of matter. Coulomb explosion of small hydrocarbons driven by strong laser pulses and electron holography of molecules are studied in a theoretical ...
