(1977)Ferroelectric crystals show an unexpected T³ᐟ² term in the specific heat. An experiment is discussed, as well as background information on ferroelectrics and specific heats, in which the thermal expansion coefficient is ...
-
(1990)A test run of a new 4π neutron detector has been performed, studying the collisions of 30 Mev/u ¹⁴N with ¹⁰⁹Ag and ⁶⁰Ni. Average neutron multiplicities of the two reactions were determined after correction for background ...
-
(1990)The purpose of this paper is to report on tests of properties of selected fiber materials and scintillation oils for their use in a liquid scintillating fiber calorimeter at the Superconducting Super Collider (SSC). The ...
-
(2009-05-15)This dissertation focuses on three separate studies. First, magnetization of the Mn12- acetate was studied by low temperature hysteresis loops and DC magnetization data on magnetically aligned Mn12-acetate micro-crystals. ...
-
(2009-06-02)In this dissertation, we systematically construct non-extremal charged rotating anti-de Sitter black hole solutions in four, five and seven dimensions. In four dimensions, we first obtain the rotating Kerr-Taub-NUT metric ...
-
(2010-01-16)The first part of this study is focused on numerical studies of light scattering from a single microscopic particle using the Discrete Dipole Approximation (DDA) method. The conventional DDA formalism is generalized to ...
-
(2009-05-15)We determine the conditions under which half-maximal matter coupled gauged supergravity in seven dimensions admits a chiral circle reduction to yield a matter coupled gauged supergravity in six dimensions with 8 real ...
-
(Texas A&M University, 2005-11-01)Explored in this report is the essential interconnectedness of Grand Unified and String Theoretic Phenomenology. In order to extract a modeled connection to low-energy physics from the context of superstring theory, it is ...

Asymptotic scattering wave function for three charged particles and astrophysical capture processes (Texas A&M University, 2006-08-16)The asymptotic behavior of the wave functions of three charged particles has been investigated. There are two different types of three-body scattering wave functions. The first type of scattering wave function evolves from ...
-
(Texas A&M University, 2005-08-29)In this work, interference and coherence phenomena, appearing in atomic and molecular ensembles interacting with coherent light sources, as electromagnetically induced transparency (EIT), coherent population trapping (CPT), ...
-
(Texas A&M University, 2007-04-25)It is generally believed that the old quantum theory, as presented by Niels Bohr in 1913, fails when applied to many-electron systems, such as molecules, and nonhydrogenic atoms. It is the central theme of this dissertation ...
-
(2009-05-15)I studied a family of closely connected topics related to the production and application of ultrashort laser pulses. I achieved broadband cascade Raman generation in crystals, producing mutually coherent frequency sidebands ...
-
(Texas A&M University, 2006-10-30)The carrier envelope (CE) phase of a femtosecond laser was stabilized. The laser produces an ultra stable comb of frequency spanning the visible region and basically is an optical frequency synthesizer and ready for the ...
-
(2009-05-15)Cooperative effect in the radiation process has been studied in for more than half a century. It is important in the sense of both basic physics and applied science. In this work, we study the dynamics of the cooperative ...
-
(1995)GaSb/Sb heterostructures hold the promise of being very interesting materials. Properties introduced by the growth of the semiconductor and semi-metal together may prove to be very useful in various electronic devices. ...
-
(2010-10-12)Coherent control of laser induced processes is based on the quantum interference among multiple excitation pathways. Progress in the field has been fueled by advances in pulse shaping techniques, allowing modulation of ...
-
(Texas A&M University, 2005-02-17)A gauged SU(4) flavor symmetric hadronic Lagrangian with empirical hadron masses is constructed to study charmonium absorption and charmed hadron production in hadronic reactions. For the coupling constants, empirical ...
-
(2012-02-14)We investigate charmonium production in the hot medium created by heavy-ion collisions by setting up a framework in which in-medium charmonium properties are constrained by thermal lattice QCD (lQCD) and subsequently ...
-
(2010-07-14)We study thoroughly Casimir energy and Casimir force in a rectangular cavity and piston with various boundary conditions, for both scalar field and electromagnetic (EM) field. Using the cylinder kernel approach, we find ...
-
(Texas A&M University, 2006-08-16)Coherence and entanglement are the two key concepts that distinguish quantum mechanics from classical mechanics. Many novel phenomena occuring in the quantum world are due to these two Âphysical quantitiesÂ. They also ...
