Heavenly metal: A study of neutron-capture element abundances in metal-poor galactic halo stars.
(1998)
New abundances for neutron-capture elements in a large sample of metal-poor giants from the Bond survey in addition to 3 well known individual cases, are presented. The spectra for the Bond Giants were acquired with the ...
Collective Behaviors of Quantum Emitters Coupled to a Structured Photonic Environment
(2023-07)
The study of a quantum system coupled to an environment plays an indispensable role in expanding our understanding of quantum mechanics. It has a broad impact, encompassing fundamental inquiries in quantum physics as well ...
Confined Quantum Systems: Beyond Harmonic Order in Dimensional Perturbation Theory
(2008)
We generalize the harmonic-order N-body DPT method for an isotropically confined quantum system of identical interacting bosons to first-anharmonic order and, in principle, higher orders. We introduce a graphical decomposition ...
Many-body dimensional perturbation theory for quantum confined systems with a focus on atomic gas Bose-Einstein condensates.
(2003)
Feshbach resonances notwithstanding, most experimentally realized atomic-vapor condensates are dilute and are best described by the mean-field Gross-Pitaevskii equation. For this reason, we use dimensional scaling methods ...
Probing Dark Energy Using Galaxy Clustering Data
(2011)
Dark energy is the most important unsolved mystery in cosmology today. Galaxy clustering provides one of the prime probes of dark energy. This work is focused on developing robust analysis techniques for interpreting galaxy ...
THERMOPHOTOVOLTAIC DEVICES AND INFRARED PHOTODETECTORS BASED ON INTERBAND CASCADE STRUCTURES
(2020-05-08)
Mid-infrared (IR) optoelectronic devices form the basis for many practical applications such as thermophotovoltaic (TPV) energy conversion, gas sensing, thermal imaging, medical diagnostics, free-space communications, ...
Short range effects :
(1982)
A Yukawa-type potential is then examined and rejected, followed by a model using two particles and a sphere with a one dimensional gauge group.
A High Cadence Study of Stellar Variability: Searching for Habitable Planetary Companions Orbiting White Dwarfs with the DECam Minute Cadence Survey
(2019-07)
One outstanding question in astronomy is what happens to planetary systems as their host star evolves. Though indirect evidence such as metal polluted white dwarf atmospheres and debris disks around white dwarfs, and recent ...
Measurement of ggF and VBF Higgs boson production cross-sections in the H->WW*->evmv decay channel from pp collisions collected with the ATLAS detector at the LHC
(2019-12)
This thesis describes measurements of the inclusive Higgs boson production cross-sections via gluon-gluon fusion (ggF) and vector-boson fusion (VBF) through the H->WW*->evmv decay mode, using proton-proton collision data ...
