description: The equations of hydrodynamics are solved for a slow squeeze-Oow in the presence of a gradient of the viscosity which, in turn, is caused by a temperature gradient. The gradient induces an asymmetry of the spreading velocity and a drift of the center of mass towards the direction where the viscosity is decreasing. Due to this phenomenon, adjacent asperites in the friction zone between two solids sliding over each other experience an effective attraction.
Daily Checklist: A Visual Aid to Increase Self-Efficacy in Congestive Heart Failure Patients
Creators: name: Phifer, Leanna Dawn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Congestive heart failure (CHF) is a chronic condition that requires daily management by those affected. Readmission and mortality rates are high for congestive heart failure patients (Yancy et al., 2013). Additionally, CHF affects the health related quality of life (HRQOL) experienced by those impacted (Yancy et al., 2013). The health care costs for treatment, hospital readmissions, and management of CHF are very expensive and they are a burden to the health care system (Yancy et al., 2013). Current strategies to increase patient self-management of CHF have not proven sufficient to lower the rate of readmissions and the associated costs (Bradley et al., 2012). In addition to the current methods used to decrease readmission rates, the Daily Checklist should be given to patients upon diagnosis of CHF or before discharge from the hospital. The Daily Checklist which includes medications, exercise, daily weight, and sodium (salt) will help patients remember what steps they must take each day to control their CHF, reduce their symptoms, and prevent readmissions for exacerbations. This will increase the patient’s self-efficacy (confidence) in their ability to manage their CHF on their own and activate their motivation to perform self-care behaviors (Shively et al., 2013). The expected outcome of the Daily Checklist is increased self-efficacy and self-management of CHF, decreased hospital readmissions and early mortality, and reduced health care costs associated with managing CHF patients.

description: We define triangulated piecewise linear constant mean curvature surfaces using a variational characterization. These surfaces are critical for area amongst continuous piecewise linear variations which preserve the boundary conditions, the simplicial structures, and (in the nonminimal case) the volume to one side of the surfaces. We then find explicit formulas for complete examples, such as discrete minimal catenoids and helicoids. We use these discrete surfaces to study the index of unstable minimal surfaces, by numerically evaluating the spectra of their Jacobi operators. Our numerical estimates confirm known results on the index of some smooth minimal surfaces, and provide additional information regarding their area-reducing variations. The approach here deviates from other numerical investigations in that we add geometric interpretation to the discrete surfaces.

We performed calculations of temperature, composition and external field dependence of ferroelectric, ferromagnetic and antiferromagnetic phases transition temperatures, remanent polarization, magnetization, hysteresis loops, coercive fields, dielectric permittivity and magnetoelectric coupling. Special attention was paid to comparison of the developed theory with experiments. It appeared possible to describe adequately the main experimental results including a reasonable agreement between the shape of calculated hysteresis loops and remnant polarization value with measured loops and polarization. Information about linear and nonlinear magnetoelectric coupling coefficients was extracted from the experimental data. From the fitting of experimental data with theoretical formula it appeared possible to obtain composition dependence of Curie-Weiss constant that is known to be inversely proportional to harmonic (linear) dielectric stiffness, as well as the strong nonlinear dependence of anharmonic parameters of free energy. Keeping in mind the essential influence of these parameters on the multiferroic properties the obtained results open the way to govern practically all the material properties with the help of suitable choice of composition. The forecast of the strong enough influence of antiferrodistortive order parameter on the transition temperatures and so on the phase diagrams and properties of multiferroics is made on the basis of the developed theory.

A Comprehensive Analysis of the Escalation of Commitment in Professional Basketball
Creators: name: McCauley, Matthew
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Traditional economic theory suggests that decision makers should not allow sunk costs to shape future actions. However, empirical studies have found a commensurate relationship between sunk costs and future expenditures even when expected marginal costs exceed expected marginal benefits, an idea referred to as the “escalation of commitment.” With large sunk costs annually incurred through player drafts, executives in the high-stakes business of professional sports may be particularly prone to this irrational behavior. This research specifically examines teams’ personnel decisions in the National Basketball Association (NBA) to determine the prevalence of escalation in the league. This study finds evidence of escalation that is lower in magnitude and shorter in duration than in previous studies. While a player’s draft position continued to affect his playing time, this effect was limited to the first two years. Furthermore, draft position among first round players played a minimal, if any, role in a team’s decision to retain a player. However, under the 1999 Collective Bargaining Agreement, being drafted in the first round significantly increased a player’s chances of retainment. No such effect was seen under the 2005 CBA.

description: Der Titel verspricht eine Darstellung der Literatur um 1968, die Arbeit bringt aber eine Untersuchung zu Hans Magnus Enzensberger und dem literarischen Spannungsfeld, in dem sein Werk sich entwickelte. Freilich wird auch hier ausgespart: die Texte, mit denen die Enzensbergers verknüpft sind, sei es, daß er sie rezipierte – wie die Abhandlungen Adornos und Marcuses –, sei es, daß sie ihn inspirierten – wie die Benjamins und Bretons –, werden ausführlicher untersucht. Texte, die zur gleichen Zeit wie die Enzensbergers entstanden, aber in einem gewissen Gegensatz zu den seinen stehen – etwa die der gemäßigten Autoren der Gruppe 47 wie Günter Grass oder Hans Werner Richter –, werden nicht erwähnt. Aber auch Texte Enzensbergers, die ein Eingreifen ins politische Feld beabsichtigen – etwa die Berliner Gemeinplätze oder das Verhör von Habana –, werden nur am Rande erwähnt; gerade in diesen zeigt sich aber die Sehnsucht des Literaten, aus der Literatur heraus auf den Platz der Geschichte zu treten und Taten zu provozieren, auch blutige, um endlich den Atem der Revolution zu spüren.

Effects of damage on the scaling laws of viscous-plastic sea ice
Creators: name: Savard, Antoine
name: Tremblay, Bruno
Publisher: name: Zenodo
Year: 2023
Subjects: sea ice, viscous-plastic, damage, model, spatiotemporal scaling

description: Sea ice deformations occur along well-defined lines of deformation called linear kinematic features (LKFs), which exhibit complex laws like spatiotemporal scaling. The complexity of these interactions is undeniable, and a desirable sea ice model should represent LKFs adequately since various processes affecting heat, salt, and moisture exchange between the ocean and the atmosphere occur along these LKFs. This multifractal property of LKFs can be seen in observations and models. However, fine-scale LKFs happen at high resolution (0-2 km), and high-resolution models are costly to run, hence the importance of parametrizing these sub-grid phenomena. Different models are more or less in agreement with the observations, and one model, the Maxwell-Elasto-Brittle model (MEB), claims to reproduce the observed spatiotemporal scaling laws better than the standard viscous-plastic model (VP). One reason could be the presence of an ice damage parametrization in the MEB model that has no equivalent in the VP model. Therefore, we include a suitable damage parametrization with advection in the VP model to disentangle the effect of rheology from the effects of damage on the scaling laws. Results show that the deformation statistics in the VP model are influenced by the inclusion of damage in the model. The inclusion of this damage parametrization gives scaling exponents in agreement with the commonly accepted values computed from the RGPS observations, hinting that damage parametrizations play a crucial role in sea ice models.
Theory vs. Practice: Knowles' Andragogy and Adult Learner Perceptions of Postsecondary Writing Instruction
Creators: name: Jennings, Alyssa Nicole
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The main focus of my thesis is a case study of four adult learners’ experiences within writing courses and how these experiences reflect both class instruction and their classes’ writing assignments, which I offer as an addition to the ongoing conversation regarding composition studies and adult learners. These insights I obtained via two-part interviews with four adult learners currently enrolled in postsecondary writing courses, and I interpret them via their consistencies with Knowles’ theory of andragogy as it applies to writing instruction specifically.
However, because some educators might not be familiar with the concept of andragogy, I first outline its key aspects and how scholars’ subsequent recommendations for writing instruction reflect andragogy’s various principles.

description: In this work we present a new generic feature of PT-symmetric Bose-Einstein condensates by studying the many-particle description of a two-mode condensate with balanced gain and loss. This is achieved using a master equation in Lindblad form whose mean-field limit is a PT-symmetric Gross-Pitaevskii equation. It is shown that the purity of the condensate periodically drops to small values but then is nearly completely restored. This has a direct impact on the average contrast in interference experiments which cannot be covered by the mean-field approximation, in which a completely pure condensate is assumed.

description: The Uffizi Gallery in Florence, Italy is the home of a kilometer-long passageway called the Vasari Corridor that houses an esteemed collection of over one thousand self-portraits. The self-portrait collection was started by Cardinal Leopoldo de' Medici in the seventeenth century, and includes works by many world-renowned masters. This thesis will trace the history of the Uffizi collection’s from its seventeenth-century foundation through its expansion in the eighteenth century and analyze a number of self-portraits from the sixteenth century to the eighteenth century in order to argue that the development of the Uffizi collection had a significant impact on the genre of self-portraiture.
Implementing inverse seesaw mechanism in SU(3)xSU(4)xU(1) gauge models

description: Generating appropriate tiny neutrino masses via inverse seesaw mechanism within the framework of a particular SU(3)xSU(4)xU(1) gauge model is the main outcome of this letter. It is achieved by simply adding three singlet exotic Majorana neutrinos to the usual ones included in the three lepton quadruplet representations. The theoretical device of treating gauge models with high symmetries is the general method by Cotaescu. It provides us with a unique free parameter (a) to be tuned in order to get a realistic mass spectrum for the gauge bosons and charged fermions in the model. The overall breaking scale can be set around 1-10 TeV so its phenomenology is quite testable at present facilities.

Examination of Prospective Diagnostic Thresholds in Premenstrual Dysphoric Disorder
Creators: name: Surana, Pallavi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Premenstrual Dysphoric Disorder (PMDD) is characterized by extreme mood symptoms that emerge cyclically in the late luteal phase of the menstrual cycle and subside during menses. About 3-8% of women meet the full DSM-5 criteria for PMDD, which requires the presentation of five symptoms (at least one being an emotional symptom) following the cyclical pattern per cycle, while another 10-11% of women can be characterized as having a less severe menstrually-related mood disorder (MRMD), which requires just one emotional symptom to follow the cyclical pattern per cycle. Women with signs of MRMD have less severe emotional symptoms than those with PMDD. However, both PMDD and MRMD can cause impairment and distress severe enough to warrant treatment.
Diagnosis of PMDD or MRMD must follow strict criteria established by the DSM-5 over a period of at least two months of prospective daily symptom ratings. Since retrospective reports of these symptoms is highly subjective and inaccurate, valid diagnosis requires prospectively evaluating daily symptoms against the diagnostic criteria. Typically, symptoms are evaluated through visual inspection of daily ratings across multiple cycles; however, differences in interpretation of the diagnostic criteria during these visual inspections may lead to inconsistencies. Furthermore, the complex diagnostic criteria outlined in the DSM-5 means there is a high risk of diagnostic error due to differing practices and errors in clinical judgment. These concerns suggest the need for a more reliable method for making valid prospective diagnoses. In response to this need, Eisenlohr-Moul et al. (under review) have developed the Carolina Premenstrual Assessment Scoring System (or C-PASS), a computerized standardized diagnostic system aimed at creating shared meaning for PMDD and MRMD across laboratories. Although the C-PASS, described in more detail below, represents an essential step forward in our standardization of these diagnoses, additional work is needed to verify that the cut points selected for making the diagnosis are adequate for identifying the subgroup of women that need treatment. The purpose of the present paper is to use descriptive statistics and ROC analyses to examine how changes to these diagnostic cutoffs influence the frequency and appropriateness of diagnoses.

Variance Estimation and Confidence Interval for Ripley's K-Function under Neyman-Scott Process
Creators: name: Wu, Yunhan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Spatial data are commonly referenced in various fields. The K-function may be the most commonly used quantity to describe how clustered the spatial data are. The Ripley's K-function, an empirical estimate for the true K-function, is the most widely used estimation in the real practice. The variance estimation of the Ripley's K-function remains challenging because of the complicated spatial dependency. Besides, the performance of empirical methods, such as bootstrapping, is not satisfactory when the point pattern is different from homogeneous Poisson process. In this thesis, we aim to build-up variance estimation and confidence intervals for Ripley's K-function when the data points are clustered, in both analytical and empirical perspectives. We outline a theoretical framework for deriving the analytical variance form for Ripley’s K-function under Neyman-Scott process. We also propose the clustered marked point method to obtain confidence interval of Ripley’s K-function when the cluster membership is known. Simulation studies are implemented to compare its performance with other existing bootstrap methods. In the end, we conduct real data analysis using malaria data for children under 5 in the Democratic Republic of Congo (DRC).

description: Most stellar remnants so far have been found in binary systems, where they interact with matter from their companions. Isolated neutron stars and black holes are difficult to find as they are dark, yet they are predicted to exist in our Galaxy in vast numbers. We explored the OGLE-III database of 150 million objects observed in years 2001-2009 and found 59 microlensing events exhibiting a parallax effect due to the Earth's motion around the Sun. Combining parallax and brightness measurements from microlensing light curves with expected proper motions in the Milky Way, we identified 13 microlensing events which are consistent with having a white dwarf, neutron star or a black hole lens and we estimated their masses and distances. The most massive of our black hole candidates has 9.3 MSun and is at a distance of 2.4 kpc. The distribution of masses of our candidates indicates a continuum in mass distribution with no mass gap between neutron stars and black holes. We also present predictions on how such events will be observed by the astrometric Gaia mission.

description: This paper presents a semiclassical model for the anisotropic thermal transport in III-V semiconductor superlattices (SLs). An effective interface rms roughness is the only adjustable parameter. Thermal transport inside a layer is described by the Boltzmann transport equation in the relaxation time approximation and is affected by the relevant scattering mechanisms (three-phonon, mass-difference, and dopant and electron scattering of phonons), as well as by diffuse scattering from the interfaces captured via an effective interface scattering rate. The in-plane thermal conductivity is obtained from the layer conductivities connected in parallel. The cross-plane thermal conductivity is calculated from the layer thermal conductivities in series with one another and with thermal boundary resistances (TBRs) associated with each interface; the TBRs dominate cross-plane transport. The TBR of each interface is calculated from the transmission coefficient obtained by interpolating between the acoustic mismatch model (AMM) and the diffuse mismatch model (DMM), where the weight of the AMM transmission coefficient is the same wavelength-dependent specularity parameter related to the effective interface rms roughness that is commonly used to describe diffuse interface scattering. The model is applied to multiple III-arsenide superlattices, and the results are in very good agreement with experimental findings. The method is both simple and accurate, easy to implement, and applicable to complicated SL systems, such as the active regions of quantum cascade lasers. It is also valid for other SL material systems with high-quality interfaces and predominantly incoherent phonon transport.

A Survey of Physical Principles Attempting to Define Quantum Mechanics

Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum mechanics, one of the most successful theories in the history of science, was created to account for physical systems not describable by classical physics. Though it is consistent with all experiments conducted thus far, many of its core concepts (amplitudes, global phases, etc.) can not be directly accessed and its interpretation is still the subject of intense debate, more than 100 years since it was introduced. So, a fundamental question is why this particular mathematical model is the one that nature chooses, if indeed it is the correct model. In the past two decades there has been a renewed effort to determine what physical or informational principles define quantum mechanics. In this paper, recent attempts at establishing reasonable physical principles are reviewed and their degree of success is tabulated. An alternative approach using joint quasi-probability distributions is shown to provide a common basis of representing most of the proposed principles. It is argued that having a common representation of the principles can provide intuition and guidance to relate current principles or advance new principles. The current state of affairs, along with some alternative views are discussed.

Marketing an Ideology: An analysis of the impact of political corporate social responsibility statements on marketing strategy and millennial brand perception
Creators: name: Thompson, Lindsay
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The ability to adapt to a changing environment is essential for businesses that strive to consistently provide value to modern consumers. Characteristics of the external ecosystem in which companies operate can greatly alter the lens through which potential customers interpret corporate communications, perceive brands and ultimately make purchasing decisions. Two significant trends impacting today’s marketplace are the heightened polarization of the American political landscape and the increasing relevance of the millennial generation as a key audience. The convergence of these factors presents a need for marketing professionals to consider corporate responsibility messaging as a way to meet the needs and expectations of a generation that demands corporate action in ways that are both unprecedented and continually evolving. The relationship between politics and identity that denotes a key characteristic of the millennial generation represents an important component of understanding and appealing to the millennial demographic and psychographic. As a result, the convergence of these variables can best be examined through the use of corporate social responsibility statements as marketing tools to reach a consumer base that is redefining what it means for companies to be socially responsible.Through semi-structured personal interviews with academic experts and business professionals and a survey of millennial consumers, this study attempts to address several research questions relating to the impact of political corporate social responsibility statements on corporate marketing strategy and millennial brand perception. The results of the study indicate that the country’s political environment and the consumer power of millennials are important aspects for corporations to consider. While in most cases the presence of politics in corporate messaging creates unnecessary risk for stakeholders, there is significant opportunity to gain a competitive advantage if the product or service, brand, corporate story and target market align.

description: Activation of the Arp2/3 complex by VCA-motif-bearing actin nucleation-promoting factors results in the formation of "daughter" actin filaments branching off the sides of pre-existing "mother" filaments. Alternatively, when stimulated by SPIN90, Arp2/3 directly nucleates "linear" actin filaments. Uncovering the similarities and differences between these two mechanisms is fundamental to understanding how actin cytoskeleton dynamics are regulated. Here, analysis of individual filaments reveals that, unexpectedly, the VCA motifs of WASP, N-WASP, and WASH destabilize existing branches, as well as SPIN90-Arp2/3 at linear filament ends. Furthermore, branch stabilizer cortactin and destabilizer GMF each have a similar impact on SPIN90-activated Arp2/3. However, unlike branch junctions, SPIN90-Arp2/3 at the ends of linear filaments is not destabilized by piconewton forces and does not become less stable with time. It thus appears that linear and branched Arp2/3-generated filaments respond similarly to the regulatory proteins we have tested, albeit with some differences, but significantly differ in their responses to aging and mechanical stress. These kinetic differences likely reflect the small conformational differences recently reported between Arp2/3 in branch junctions and linear filaments and suggest that their turnover in cells may be differently regulated.
Should REIT Investor Care About Cash Flow?
Creators: name: Ye, Zicheng
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: In this study, we ask whether firms with differing cash flow variability have different impacts upon the benefits to portfolio diversification. We focus our attention on REITs since they offer a unique venue to gauge the importance of cash flow variability, and we judge benefits to diversification through a utility framework predicated upon Boudry et al. Using data from 2011 through 2017, we find three main results. First, the relation between cash flow variations and portfolio diversification benefits exists but are not robust across different cash flow measures and choices for diversification benefits. Second, risk-averse investors favor REITs with higher or lower cash flow variations more than REITs with medium cash flow variations. Finally, some subsets of REITs provide additional information to cash flow variations and diversification benefits.

Sensitivity and foreground modelling for large-scale CMB B-mode polarization satellite missions

description: The measurement of the large-scale B-mode polarization in the cosmic microwave background (CMB) is a fundamental goal of future CMB experiments. However, because of unprecedented sensitivity, future CMB experiments will be much more sensitive to any imperfect modelling of the Galactic foreground polarization in the reconstruction of the primordial B-mode signal. We compare the sensitivity to B-modes of different concepts of CMB satellite missions (LiteBIRD, COrE, COrE+, PRISM, EPIC, PIXIE) in the presence of Galactic foregrounds. In particular, we quantify the impact on the tensor-to-scalar parameter of incorrect foreground modelling in the component separation process. Using Bayesian fitting and Gibbs sampling, we perform the separation of the CMB and Galactic foreground B-modes. The recovered CMB B-mode power spectrum is used to compute the likelihood distribution of the tensor-to-scalar ratio. We focus the analysis to the very large angular scales that can be probed only by CMB space missions, i.e. the Reionization bump, where primordial B-modes dominate over spurious B-modes induced by gravitational lensing. We find that fitting a single modified blackbody component for thermal dust where the "real" sky consists of two dust components strongly bias the estimation of the tensor-to-scalar ratio by more than 5σ for the most sensitive experiments. Neglecting in the parametric model the curvature of the synchrotron spectral index may bias the estimated tensor-to-scalar ratio by more than 1σ. For sensitive CMB experiments, omitting in the foreground modelling a 1% polarized spinning dust component may induce a non-negligible bias in the estimated tensor-to-scalar ratio.

Periods, Prayer, and Purity: Menstrual Health Practices Within the Sikh Tradition
Creators: name: Deol, Preeya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This thesis project is centered on my personal experience, as well as the experiences of thirteen females within the Sikh community. These women, along with myself, represent members of the South Asian diaspora. Keeping that in mind, there are many gaps in the literature in terms of where the voices are coming from and from the world, which ones are represented. With this research, I aim to shed light on how some Sikh women emotionally, mentally, as well as physically manage their menstrual cycles. This project comes at a time where revolutions are occurring. People around the world are pushing to make a change around what we see as menstruation and why generations of people still see it as a taboo and unacceptable topic of discussion. As this field of research grows, I desire that my work with Sikh females can create content for scholars and the community to read, understand, and gain insight from, specifically tackling issues of access, education, and possible policy change.
Benefits of tolerance in public goods games

description: Leaving the joint enterprise when defection is unveiled is always a viable option to avoid being exploited. Although loner strategy helps the population not to be trapped into the tragedy of the commons state, it could offer only a modest income for non-participants. In this paper we demonstrate that showing some tolerance toward defectors could not only save cooperation in harsh environments, but in fact results in a surprisingly high average payoff for group members in public goods games. Phase diagrams and the underlying spatial patterns reveal the high complexity of evolving states where cyclic dominant strategies or two-strategy alliances can characterize the final state of evolution. We identify microscopic mechanisms which are responsible for the superiority of global solutions containing tolerant players. This phenomenon is robust and can be observed both in well-mixed and in structured populations highlighting the importance of tolerance in our everyday life.

description: In this paper, we compute a recursive wall-crossing formula for the Poincaré polynomials and Euler characteristics of Abelian symplectic quotients of a complex projective manifold under a special effective action of a torus with non-trivial characters. An analogy can be made with the space of pure states of a composite quantum system containing $r$ quantum bits under action of the maximal torus of Local Unitary operations.
Digital Persuasion: Jane Austen's Persuasion as a Test Case for Mapping, Visualization, and Interpretation in the Digital Humanities
Creators: name: Koeze, Ella Winthrop
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Despite the fact that digital humanities have become a recognized force in contemporary
academic studies, the potential of this force for transforming the nature of literary studies has yet
to be determined. Scholars like Kathleen Fitzpatrick express excitement for “the difference that
the digital can make to the kinds of work that we do as well as to the ways that we communicate
with one another” without necessarily articulating what that difference will be (Fitzpatrick).
Alvarado insists that digital humanists must be deeply interested in the reimagining and
reworking of knowledge. He sees digital humanists sharing “a common element of play, of
productively mapping and remapping the objects and categories of scholarship onto the rapidly
changing, intrinsically plastic but structurally constraining media of digital technology”
(Alvarado). Alvarado even goes so far as to say that “without this play—to the extent that the
scholar has a standoffish, do-this-for-me attitude toward the medium—then, no, she is not a
digital humanist” (Alvarado). In this sense, digital humanists in literary studies are not simply
concerned with the interpretation of a text, but with the new, emergent ways that interpretations
are produced and represented.
So where does this project, “Digital Persuasion,” fit in? My initial goal was to simply see
what was possible, using Jane Austen’s Persuasion as a test case for mapping and visualizing a
novel. I wanted to discover what would happen if I applied digital methods to a close analysis of
a single text. As I progressed, however, I found myself constantly faced with unforeseen
questions of the human role in textual interpretation and analysis, despite my use of digital tools.
And when I finally created my visualizations, I was further faced with the question of the value
of my work. I had seen what I could accomplish, but had I discovered anything new or
transformative? “Digital Persuasion” is thus an attempt to enter the conversation on these topics,
using experiences in visualizing Persuasion as evidence for my positions.

A Cold-Strontium Laser in the Superradiant Crossover Regime

description: Recent proposals suggest that lasers based on narrow dipole-forbidden transitions in cold alkaline earth atoms could achieve linewidths that are orders of magnitude smaller than linewidths of any existing lasers. Here, we demonstrate a laser based on the 7.5 kHz linewidth dipole forbidden $^3 $P$_1$ to $^1 $S$_0$ transition in laser-cooled and tightly confined $^{88}$Sr. We can operate this laser in the bad-cavity regime, where coherence is primarily stored in the atoms, or continuously tune to the more conventional good-cavity regime, where coherence is primarily stored in the light field. We show that the cold-atom gain medium can be repumped to achieve quasi steady-state lasing, and demonstrate up to an order of magnitude suppression in the sensitivity of laser frequency to changes in cavity length, the primary limitation for the most frequency stable lasers today.
