Renormalization-Group Approach To The Normal Phase Of Two-Dimensional Fermi Gases, S. Laalitya Uppalapati, Daniel E. Sheehy

Faculty Publications

We present results on the effect of short-range, attractive interactions on the properties of balanced tw-dimensional Fermi gases in the nonsuperfluid (normal) phase. Our approach combines the renormalization group (RG) with perturbation theory, yielding observables such as the equation of state and compressibility. We find good agreement with recent experiments that measured the equation of state in trapped gases in the balanced regime, showing that these results are consistent with logarithmic corrections in the equation of state.

Effects Of Sea-Level Rise On Physiological Ecology Of Populations Of A Ground-Dwelling Ant, L. M. Hooper-Bùi, R. M. Strecker-Lau, D. M. Stewart, M. J. Landry, A. M. Papillion, S. N. Peterson, R. A. Daniel

Faculty Publications

Introduction Sea-level rise is a consequence of climate change that can impact the ecological and physiological changes of coastal, ground-dwelling species. Sea-level rise has a potential to inundate birds, rodents, spiders, and insects that live on the ground in coastal areas. Yet, there is still much to be learned concerning the specifics of these impacts. The red imported fire ant Solenopsis invicta (Buren) excavates soil for its home and is capable of surviving flooding. Because of their ground-dwelling life history and rapid reproduction, fire ants make an ideal model for discovery and prediction of changes that may be due to …

A New Proposal For The M + A Methodology In Segregating Populations Of Cowpea, Renata Fernandes De Matos, Antônio Moreira Barroso Neto, Júlio César Dovale, Cândida Hermínia Campos De Magalhães Bertini, Roberto Fritsche-Neto

Faculty Publications

The evaluation of segregating populations in plant breeding programs is an onerous and time-consuming process. Early identification of populations with genetic potential can be done by m + a methodology. However, the possibility of a modification in the traditional methodology in order to make it more efficient, that is, faster and cheaper, was envisaged. Thus, the objective of this study was to compare the genetic gains obtained by both methodologies, the traditional one and the proposed modification. For this, ten segregating bean-cowpea populations were evaluated at two distinct levels of homozygous F3:4 and F3:5. Genetic values were predicted by two …

Noise Resilience Of Variational Quantum Compiling, Kunal Sharma, Sumeet Khatri2, M. Cerezo, Patrick J. Coles

Faculty Publications

Variational hybrid quantum-classical algorithms (VHQCAs) are near-term algorithms that leverage classical optimization to minimize a cost function, which is efficiently evaluated on a quantum computer. Recently VHQCAs have been proposed for quantum compiling, where a target unitary U is compiled into a short-depth gate sequence V. In this work, we report on a surprising form of noise resilience for these algorithms. Namely, we find one often learns the correct gate sequence V (i.e. the correct variational parameters) despite various sources of incoherent noise acting during the cost-evaluation circuit. Our main results are rigorous theorems stating that the optimal variational parameters …

Tunable Luminescence Of Rare Earth Doped Nanophosphors Via Adaptive Optical Properties Of Transition Metals, Pragathi Darapaneni

LSU Doctoral Dissertations

Over the past decades, the development of light-emitting diodes (LEDs) to produce a wide range of wavelengths has revolutionized the solid-state lighting industry due to their higher energy efficiency and operational lifetimes. These LEDs employ rare earth (RE) doped phosphors due to their stable emission wavelengths which can be amplified when sensitized by other RE dopants (Yb, Ce) or shell layer passivation. However, there has been a push to replace the RE elements in LEDs due to increased socioeconomic issues. One proposed alternative, transition metal (TM) dopants, is typically avoided due to their susceptibility to the local crystal environment resulting …

Vegetation Prior To And During Onset Of East Antarctic Glaciation: High Resolution Palynological Insights From Sabrina Coast, East Antarctica, Meghan L. Duffy

LSU Master's Theses

The Aurora Subglacial Basin (ASB) contains an estimated 3.5 m of global sea-level equivalent ice volume and is primarily drained by the Totten Glacier system, which terminates at the Sabrina Coast, East Antarctica. Thinning and retreating of the Totten Glacier indicate that this region is highly susceptible to oceanographic and atmospheric warming. The paleoclimate reconstruction of these changes, conducted in the context of this MS thesis, will improve understanding of East Antarctic Ice Sheet (EAIS) dynamics in this sensitive system. A recent study used seismic and sediment core data to document a dynamic early evolution of the EAIS in the …

Community Dynamics Of Fish Assemblages On Mid-Shelf And Outer-Shelf Coral Reefs In The Northwestern Gulf Of Mexico, Lynne S. Wetmore, Michael A. Dance, Ronald L. Hill, Jay R. Rooker

Faculty Publications

Offshore coral reefs in the Gulf of Mexico (GOM) are unique model systems for examining the mechanisms structuring reef fish communities due to their substantial geographic isolation, and the presence of replicate experimental units of both low (mid-shelf) and high coral diversity (shelf-edge) reefs. Here, we examined the species assemblage structure of juvenile and adult fishes at two mid-shelf reefs (Sonnier and Stetson Bank) and two shelf-edge reefs (East and West Flower Garden Banks) in the northwestern GOM to evaluate the relative importance of habitat (i.e., coral diversity) vs. recruitment in structuring resident fish assemblages. Visual reef fish surveys (n …

Transition Metal-Doped Rare-Earth Oxysulfide Catalysts For High Temperature Dry Reforming Of Methane, Changyi Jiang

LSU Doctoral Dissertations

Carbon dioxide reforming of methane is a catalytic reaction utilizing two kinds of greenhouse gases and converting them into a useful industrial gas stream, “syngas”. However, sulfur poisoning and coke formation are two major challenges for this reaction. In this study, we have synthesized and examined several Ce-La and Ce-Zr oxides, with different transition metal additives. A rapid screening technique was developed to measure reforming and coking rates at low partial pressures. It is a good indicator of catalyst behavior at higher conversions and partial pressures. Following the rapid screening, select catalysts were examined at longer times on stream. Those …

Genomics And Population History Of Black-Headed Bulbul (Brachypodius Atriceps) Color Morphs, Subir B. Shakya

LSU Doctoral Dissertations

Intraspecific polymorphism in birds, especially color polymorphism, is an area of active research in evolutionary biology. In this dissertation, I applied WGS to uncover the potential genetic underpinnings of color polymorphism in the Black-headed Bulbul (Brachypodius atriceps) of Southeast Asia. This species was selected because of the heterogeneous dispersion of two morphs across its range: a yellow form predominating on mainland Asia and the Greater Sunda Islands and a gray morph on two islands—Bawean and Maratua.

I approached this project from three angles. First, I reconstructed the phylogeny of the bulbul family, Pycnonotidae, to examine patterns of coloration …

"There Is Enough Food On The Table": Religious Minority Students' Experiences With The Campus Spiritual Climate, Regina C. Schneider

LSU Master's Theses

Within the last 30 years, diversity, equity, and inclusion initiatives have been at much of the forefront of student affairs and higher education policy and practices. Issues regarding gender, race, and socioeconomic status have received much attention not only in education, but also in the greater landscape of the nation. Religious and spiritual minority students are a population that has only recently been considered in fostering a more inclusive and pluralistic college environment. Thus, there is a research gap involving religious/spiritual minority college students and their perceptions of the campus climate. Additionally, only a small pool of research addresses the …

Examining Political Ambition: Competition And Leadership In Youth Activities, Ashley Staszak

LSU Master's Theses

Significant amounts of previous research focused on political ambition as a source of the gender gap in representation (Beyer and Bowden 1997; Pajares 2002; Fox 2010; Fox and Lawless 2014). This research looks to examine extracurricular activities (or after-school activities) and the effects they have on political ambition of girls as they grow up. Extracurricular activities provide girls access to competition, risk and female role models which can work to combat gender role socialization and other hindrances to running for political office. Using a survey of 300 undergraduate students at a large southern university, I measure the effect of extracurricular …

Constraining Prograde Metamorphic Paths In Archean High-Grade Garnet-Bearing Lithologies From The Eastern Beartooth Mountains, Montana, Usa, Larry Fisher Cliff-Tuttle Jr

LSU Master's Theses

Prograde metamorphic pressures and temperatures of Archean high-grade garnet-bearing lithologies from the eastern Beartooth Mountains of Montana provide an important constraint on the tectonometamorphic history of this terrane and the early Earth in general. A particularly useful means to approximate prograde metamorphic conditions is examining entrapment conditions of garnet mineral inclusions during garnet growth. Lithologies of the eastern Beartooth Mountains are well-suited to this approach because of the presence of abundant mineral inclusions within garnet porphyroblasts. Consequently, prograde metamorphic pressures and temperatures in the Beartooth Mountains, conditions that have only been broadly constrained previously, can be more accurately determined and …

Acoustic Measures Of The Singing Voice In Secondary School Students, Elizabeth M. Wallace

LSU Doctoral Dissertations

Descriptions of voice quality in vocal and choral music often rely on subjective terminology, which may be perceived differently between individuals. As access to software used in acoustic measurement becomes more widespread and affordable, music educators can potentially combine traditional descriptive terminology with objective acoustic descriptors and data, which may improve both teaching and singing. The secondary school choral music educator has specific challenges, in that they teach students who experience drastic physical and acoustic changes of the voice as they grow from children to adults. The purpose of this study was to objectively analyze various acoustic characteristics of the …
