Effects of selection and covariance on X-ray scaling relations of galaxy clusters
(Blackwell Publishing, 2008-01-01)
We explore how the behaviour of galaxy cluster scaling relations are affected by flux-limited selection biases and intrinsic covariance among observable properties. Our models presume log-normal covariance between luminosity ...
Virial scaling of massive dark matter halos: Why clusters prefer a high normalization cosmology
(Univ Chicago Press, 2008-01-01)
We present a precise estimate of the bulk virial scaling relation of halos formed via hierarchical clustering in an ensemble of simulated cold dark matter cosmologies. The result is insensitive to cosmological parameters; ...
Immersion scatterometry for improved nano-scale topography measurements
(WILEY-VCH Verlag, 2008-04)
Spectroscopic ellipsometry measurement of periodic structures (“scatterometry”) has become a standard method for critical dimension and topography measurement in the integrated circuit industry. As dimensions are reduced, ...
Katherine Chamberlain: A Snapshot of the Life
(2008-01-14)
This working paper provides a summary of an investigation in the the life of Katherine Chamberlain, the first woman to earn a PhD in Physics from the University of Michigan. It was written as the conclusion of a research ...
Quantum Optical Implementation of Quantum Information Processing and Classical Simulation of Many-Body Physics from Quantum Information Perspective.
(2008)
This thesis is composed of two parts. In the first part we summarize our study
on implementation of quantum information processing (QIP) in optical cavity QED
systems, while in the second part we present our numerical ...
Ultrafast Transient Absorption Studies of Environment Influence on the Photolysis of B12 Complexes and the Subsequent Recombination and Escape of Caged Radicals.
(2008)
Femtosecond to nanosecond transient absorption experiments were performed on a series of B12 complexes to assess the influence of the solvent environment on the excited state electronic structure and resulting dynamics. ...
Electron and Proton Acceleration Using the 30 TW, 30 fs Hercules Laser.
(2008)
This thesis presents experimental measurements of energetic particles accelerated from a high intensity, short pulse interaction with underdense and overdense plasmas.
From the interaction of a 40 TW laser pulse with an ...
Cold Neutral Atoms in Optical Lattices.
(2008)
In this thesis, I study the properties of cold neutral atoms, including Bose-Einstein
condensates (BEC), inside periodic light-shift potentials created by optical lattices.
In the first part, a new optical-lattice scheme, ...
Achieving High Spin-Flip Efficiency with an RF Magnet and Discovery of Spin-Resonance Strength Formulae Problem.
(2008)
Frequent polarization reversals, or spin-flips, of a beam in high energy storage rings, may be a powerful tool for greatly reducing the systematic errors of spin asymmetry measurements in scattering experiments. A spin-flipping ...
