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 ...
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 ...
Probing Heavy Spin-2 Bosons with γγ final states from Vector Boson Fusion Processes at the LHC
(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 ...
Real-time real-space density functional theory calculations of electron scattering in materials
(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 ...
Density profiles of dark matter halos
(Vanderbilt University. Dept. of Physics and Astronomy, 2010-04)
A web-based application of the Cellular Force Inference Toolkit (CellFIT)
(Vanderbilt University. Dept. of Physics and Astronomy, 2019-04-18)
Given an image of an epithelial cell sheet, CellFIT can infer cellular forces by segmenting the image into individual cells, constructing equilibrium equations for the points where cells meet at triple junctions, and finding ...
Axionlike Dark Energy and Particle Decay in theFuture of the Accelerating Universe
(Vanderbilt University. Dept. of Physics and Astronomy, 2021-04-30)
The 1998 discovery that the universe was accelerating in its expansion has yet to be explained
theoretically, meriting the continual theoretical and observational study of this phenomena.
In this thesis, we undergo a ...
Expected Host Galaxy Properties of PTA Detectable Massive Black Hole Binaries
(Vanderbilt University. Dept. of Physics and Astronomy, 2021-12-06)
Massive black hole binaries (MBHB) produce gravitational waves (GW) that will be detectable with pulsar timing arrays within the next few years. We determine the properties of the host galaxies of MBHB at the time they are ...
