First observation of the direct detection of positive D-meson into anti-K-long + 3 pions and negative D-meson into K-long + 3 pions with the Fermilab FOCUS experiment
(Vanderbilt University. Department of Physics and Astronomy, 2014-04)
In this thesis the decays of positive D-mesons into neutral anti-K-mesons and
three charged pions and of negative D-mesons into neutral K-mesons and three
charged pions are reconstructed in both long and short neutral ...
Thermal fabrication of gold nanocages
(Vanderbilt University. Department of Physics and Astronomy, 2011-04-11)
The purpose of this research project was to test and characterize a new method
for gold nanoparticle production. The main idea was based on the preliminary
observations made in earlier work, which had suggested that small ...
The quadratic approximation for quintessence with arbitrary initial conditions
(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 ...
Emittance and entropy of electron beams
(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 ...
Ps2- in a magnetic field : structure and stability in the M=0 state.
(Vanderbilt University. Dept. of Physics and Astronomy, 2016-05-02)
The energy of the Ps2- (three electrons and two positrons or vice versa) system and all possible fragmentations are calculated in a magnetic field in their M=0 states using the stochastic variational method with a deformed ...
Finite-Element Analysis of Low-Power Laser Heating in Gold::Vanadium Dioxide Nanocomposites
(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 ...
Nanoscale dolmen structure exhibiting a tunable Fano resonance
(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 ...
Exploring the Local Association : a nearby, young kinematic stream of stars in the solar neighborhood
(Vanderbilt University. Dept. of Physics & Astronomy, 2008)
During the course of my Honors Research Project, I worked with Dr. David
James to determine whether a group of target stars are members of the Local Association.
I did this by reducing spectroscopic data, taken by Dr. ...
LieART 2.0--An Improved Way to Compute Branching Rules
(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 ...
Reflection and rotation for three dimensional microscopy of live cells
(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 ...
