description: We investigate the influence of an electric field on trapped modes arising in a two-dimensional curved quantum waveguide ${\bf Ω}$ i.e. bound states of the corresponding Laplace operator $-Δ\_{\bf Ω}$. Here the curvature of the guide is supposed to satisfy some assumptions of analyticity, and decays as $O(|s|^{-\varepsilon}), \varepsilon > 3$ at infinity. We show that under conditions on the electric field $ \bf F$, ${\bf H}(F):= -Δ\_{\bf Ω} + {\bf F}. {\bf x} $ has resonances near the discrete eigenvalues of $-Δ\_{\bf Ω}$.

description: We study the vortex lattice in a two-dimensional s-wave topological superconductor with Rashba spin-orbit coupling and Zeeman field by solving the Bogoliubov-de Gennes equations self-consistently for the superconducting order parameter. We find that when spin-orbit coupling is relatively weak, one of the two underlying chiralities in the topological superconducting state can be strongly manifest in the vortex core structure and govern the response of the system to vorticity and a nonmagnetic impurity where the vortex is pinned. The Majorana zero mode in the vortex core is found to be robust against the nonmagnetic impurity in that it remains effectively a zero-energy bound state regardless of the impurity potential strength and the major chirality. The spin polarization of the Majorana bound state depends on the major chirality for weak spin-orbit coupling, while it is determined simply by the vorticity when spin-orbit coupling is relatively strong.

description: The purpose of this article is to review the current status of a frontier in dynamic spintronics and contemporary magnetism, in which much progress has been made in the past decade, based on the creation of a variety of micro- and nano-structured devices that enable electrical detection of magnetization dynamics. The primary focus is on the physics of spin rectification effects, which are well suited for studying magnetization dynamics and spin transport in a variety of magnetic materials and spintronic devices. Intended to be intelligible to a broad audience, the paper begins with a pedagogical introduction, comparing the methods of electrical detection of charge and spin dynamics in semiconductors and magnetic materials respectively. After that it provides a comprehensive account of the theoretical study of both the angular dependence and line shape of electrically detected ferromagnetic resonance (FMR), which is summarized in a handbook formate easy to be used for analyzing experimental data. We then review and examine the similarity and differences of various spin rectification effects found in ferromagnetic films, magnetic bilayers and magnetic tunnel junctions, including a discussion of how to properly distinguish spin rectification from the spin pumping/inverse spin Hall effect generated voltage. After this we review the broad applications of rectification effects for studying spin waves, nonlinear dynamics, domain wall dynamics, spin current, and microwave imaging. We also discuss spin rectification in ferromagnetic semiconductors. The paper concludes with both historical and future perspectives, by summarizing and comparing three generations of FMR spectroscopy which have been developed for studying magnetization dynamics.

Implementation and evaluation of an evidence-based skin care bundle in preventing and managing incontinence associated dermatitis in a medical surgical unit
Creators: name: Okoduwa, Angela
Publisher: name: No Publisher Supplied
Year: 2023

description: PURPOSE OF PROJECT: This quality improvement project aimed to reduce the rate of incontinence-associated dermatitis, enhance nursing knowledge, and implement an evidence-based skin care bundle for incontinent adult patients in a medical-surgical unit. METHODOLOGY: The project involved a 3-month retrospective and prospective chart analysis of 100 patients who were incontinent of stool or urine. The nursing staff received education for two weeks about incontinence-associated dermatitis, followed by implementing the incontinence-associated dermatitis skincare bundle and the treatment algorithm. RESULTS: A total of 100 charts were reviewed, 50 pre- and 50 post-implementations. The incontinence-associated dermatitis rate decreased from 62.2% to 14.9% (p < 0.001). Documentation of the use of containment devices by nurses increased from 40% to 61.7% ( p = 0.03). Likewise, documentation of barrier skin protectants increased from 95.6% to 100% ( p = 0.095). However, documentation in the use of treatment measures, such as critic-aid in erythema, decreased from 17.8% to 10.6% (p = 0.248), and TRIAD for skin erosion decreased from 4.4% to 4.3% (p = 0.675).IMPLICATION FOR PRACTICE: The rate of incontinence-associated dermatitis decreased post-implementation of the skin care bundle. Use of an evidence-based skincare bundle can help reduce the rate of incontinence-associated dermatitis, enhance nursing knowledge, and help improve patient outcomes while reducing healthcare costs.

Quantum Errors and Disturbances: Response to Busch, Lahti and Werner

Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Busch, Lahti and Werner (BLW) have recently criticized the operator approach to the description of quantum errors and disturbances. Their criticisms are justified to the extent that the physical meaning of the operator definitions has not hitherto been adequately explained. We rectify that omission. We then examine BLW's criticisms in the light of our analysis. We argue that, although the approach BLW favour (based on the Wasserstein 2-deviation) has its uses, there are important physical situations where an operator approach is preferable. We also discuss the reason why the error-disturbance relation is still giving rise to controversies almost a century after Heisenberg first stated his microscope argument. We argue that the source of the difficulties is the problem of interpretation, which is not so wholly disconnected from experimental practicalities as is sometimes supposed.

title: Experimental and Computational Aerodynamic Studies of Axially-Oriented Low-Fineness-Ratio Cylinders
Creators: name: Miller, Forrest
Publisher: name: Old Dominion University Libraries
Year: 2023

description: For the successful completion of atmospheric entry, descent, and landing (EDL) missions, a body geometry must be selected which provides favorable dynamic aerodynamic properties. The types of experimental facilities capable of collecting information on these properties are limited; however, their numbers are growing thanks to the continued work by the aerodynamics community. NASA Langley Research Center (LaRC) is conducting dynamic aerodynamic testing using a subsonic magnetic suspension and balance system (MSBS), with the end goal of implementing a supersonic MSBS facility at NASA Glenn Research Center. MSBSs are also currently used at the Institute of Fluid Science (IFS) at Tohoku University in Japan for blunt body testing. With the MSBS community growing, there is an opportunity for collaboration in overlapping areas of interests, particularly in expanding general blunt body theory and estimating EDL vehicle performance using these modern facilities.

The work encompassed in this thesis is a product of such a collaboration, with the specific subject of examination being an axially-oriented low-fineness-ratio cylinder. This geometry which has been previously tested at the IFS facility in Japan, was used as the basis for a multi-faceted campaign at the NASA LaRC MSBS, the Old Dominion University (ODU) low-speed wind tunnel, and computational fluid dynamic (CFD) simulations on the ODU high-performance computing cluster (HPC). Static tests were performed at the ODU wind tunnel on a 6′′ diameter model and were accompanied by static CFD simulations. Dynamic testing was performed at the NASA LaRC MSBS facilities on two 1.75′′ diameter models with varied gravitational centers and were accompanied by a dynamic CFD simulation.

The experimental and computational goals were met, with results for static and dynamic aerodynamic forces as well as flow visualization being compared and contrasted. There was reasonable agreement between the static results with empirical data as well as the dynamic results. In particular, the agreements with empirical results for pitch angles from 0◦ to 90◦ stand as a significant validation to the scarce data that exists in this region.

description: Characterizing inhomogeneous temporal patterns in natural and social phenomena is important to understand underlying mechanisms behind such complex systems, hence even to predict and control them. Temporal inhomogeneities in event sequences have been described in terms of bursts that are rapidly occurring events in short time periods alternating with long inactive periods. The bursts can be quantified by a simple measure, called burstiness parameter, which was introduced by Goh and Barabási [EPL \textbf{81}, 48002 (2008)]. The burstiness parameter has been widely used due to its simplicity, which however turns out to be strongly affected by the finite number of events in the time series. As the finite-size effects on burstiness parameter have been largely ignored, we analytically investigate the finite-size effects of the burstiness parameter. Then we suggest an alternative definition of burstiness that is free from finite-size effects and yet simple. Using our alternative burstiness measure, one can distinguish the finite-size effects from the intrinsic bursty properties in the time series. We also demonstrate the advantages of our burstiness measure by analyzing empirical datasets.

Macroscopic Quantum Superposition in Cavity Optomechanics

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

description: Quantum superposition in mechanical systems is not only key evidence for macroscopic quantum coherence, but can also be utilized in modern quantum technology. Here we propose an efficient approach for creating macroscopically distinct mechanical superposition states in a two-mode optomechanical system. Photon hopping between the two cavity modes is modulated sinusoidally. The modulated photon tunneling enables an ultrastrong radiation-pressure force acting on the mechanical resonator, and hence significantly increases the mechanical displacement induced by a single photon. We study systematically the generation of the Yurke-Stoler-like states in the presence of system dissipations. We also discuss the experimental implementation of this scheme.

description: Weyl semimetals and nodal line semimetals are characterized by linear band touching at zero-dimensional points and one-dimensional lines, respectively. We predict that a circularly polarized light drives nodal line semimetals into Weyl semimetals. The Floquet Weyl points thus obtained are tunable by the incident light, which enables investigations of them in a highly controllable manner. The transition from nodal line semimetals to Weyl semimetals is accompanied by the emergence of a large and tunable anomalous Hall conductivity. Our predictions are experimentally testable by transport measurement in film samples or by pump-probe angle-resolved photoemission spectroscopy.

description: By combining angle-resolved photoemission spectroscopy and quantum oscillation measurements, we performed a comprehensive investigation on the electronic structure of LaSb, which exhibits near-quadratic extremely large magnetoresistance (XMR) without any sign of saturation at magnetic fields as high as 40 T. We clearly resolve one spherical and one intersecting-ellipsoidal hole Fermi surfaces (FSs) at the Brillouin zone (BZ) center $Γ$ and one ellipsoidal electron FS at the BZ boundary $X$. The hole and electron carriers calculated from the enclosed FS volumes are perfectly compensated, and the carrier compensation is unaffected by temperature. We further reveal that LaSb is topologically trivial but share many similarities with the Weyl semimetal TaAs family in the bulk electronic structure. Based on these results, we have examined the mechanisms that have been proposed so far to explain the near-quadratic XMR in semimetals.

Οι συγκρούσεις πτηνών με τις ανεμογεννήτριες και η αντιμετώπιση αυτών, οι κλιματολογικές αλλαγές και το πώς επηρεάζουν αυτές την δομική ακεραιότητα των ανεμογεννητριών είναι μερικές από τις εφαρμογές που έχουν οι αισθητήρες και οι οπτικές ίνες στην πρόβλεψη της δομικής ακεραιότητας των ανεμογεννητριών.

description: Η τρισδιάστατη εκτύπωση είναι μια τεχνολογία κατασκευής πρόσθετων (Additive Manufacturing – AM) που έκανε την εμφάνισή της την δεκαετία του ’80 από τον Chuck Hull. Στις ΑΜ τεχνολογίες τα τρισδιάστατα ψηφιακά μοντέλα μετατρέπονται σε φυσικά αντικείμενα. Οι τρισδιάστατοι εκτυπωτές ακολουθούν διαδικασίες, ανάλογα με τις ανάγκες του κατασκευαστή καθώς και με τα υλικά που επιθυμεί να χρησιμοποιήσει. Διαδικασίες, όπως η σύντηξη σκόνης και εκτόξευση υλικού, ο φωτοπολυμερισμός, η σύντηξη σκόνης πάνω σε στρώμα, η συγκόλληση φύλλων, είναι από τις πιο συνηθισμένες. Η ραγδαία ανάπτυξη της τεχνολογίας και η εξέλιξη της ιατρικής επιστήμης μας επέτρεψε να κατασκευάσουμε τρισδιάστατα εκτυπωμένα ανατομικά μοντέλα, προσφέροντας εξατομικευμένες λύσεις σε προβλήματα ασθενών. Η εργασία αναφέρεται σε εφαρμογές της τρισδιάστατης εκτύπωσης στον τομέα της Ορθοπαιδικής χειρουργικής, και συγκεκριμένα στην αντικατάσταση ισχίου. Θεωρήθηκε όμως απαραίτητο αρχικά να γίνει αναφορά στην Βιοϊατρική Τεχνολογία, καθώς και στην εξέλιξη των βιοϋλικών. Στη συνέχεια, κρίθηκε σκόπιμο να παρουσιαστούν οι τεχνολογίες και οι μέθοδοι της τρισδιάστατης εκτύπωσης, ώστε να καταλήξουμε στο επόμενο κεφάλαιο στις προσφορότερες τεχνολογίες εκτύπωσης με χρήση βιοϋλικών μέχρι σήμερα. Τέλος, παρουσιάζεται στην εργασία η διαδικασία κατασκευής ομοιώματος ισχίου με FDM εκτυπωτή και υλικά που είχαμε στη διάθεσή μας, ώστε να καταλήξουμε σε συμπεράσματα που αφορούν στην αναγκαιότητα σύνδεσης της τρισδιάστατης εκτύπωσης με την ιατρική.

description: Adiabatic pulses are used extensively to enable robust control of quantum operations. We introduce a new approach to adiabatic control that uses the superadiabatic quality or $Q$-factor as a performance metric to design robust, high fidelity pulses. This approach permits the systematic design of quantum control schemes to maximize the adiabaticity of a unitary operation in a particular time interval given the available control resources. The interplay between adiabaticity, fidelity and robustness of the resulting pulses is examined for the case of single-qubit inversion, and superadiabatic pulses are demonstrated to have improved robustness to control errors. A numerical search strategy is developed to find a broader class of adiabatic operations, including multi-qubit adiabatic unitaries. We illustrate the utility of this search strategy by designing control waveforms that adiabatically implement a two-qubit entangling gate for a model NMR system.

description: MnP, a superconductor under pressure, exhibits a ferromagnetic order below TC~290 K followed by a helical order with the spins lying in the ab plane and the helical rotation propagating along the c axis below Ts~50 K at ambient pressure. We performed single crystal neutron diffraction experiments to determine the magnetic ground states under pressure. Both TC and Ts are gradually suppressed with increasing pressure and the helical order disappears at ~1.2 GPa. At intermediate pressures of 1.8 and 2.0 GPa, the ferromagnetic order first develops and changes to a conical or two-phase (ferromagnetic and helical) structure with the propagation along the b axis below a characteristic temperature. At 3.8 GPa, a helical magnetic order appears below 208 K, which hosts the spins in the ac plane and the propagation along the b axis. The period of this b axis modulation is shorter than that at 1.8 GPa. Our results indicate that the magnetic phase in the vicinity of the superconducting phase may have a helical magnetic correlation along the b axis.

description: We present an optimal analysis for a quantum mechanical engine working between two energy baths within the framework of relativistic quantum mechanics, adopting a first-order correction. This quantum mechanical engine, with the direct energy leakage between the energy baths, consists of two adiabatic and two isoenergetic processes and uses a three-level system of two non-interacting fermions as its working substance. Assuming that the potential wall moves at a finite speed, we derive the expression of power output and, in particular, reproduce the expression for the efficiency at maximum power.

description: Particle dynamics in the electron current layer in collisionless magnetic reconnection is investigated by using a particle-in-cell simulation. Electron motion and velocity distribution functions are studied by tracking self-consistent trajectories. New classes of electron orbits are discovered: figure-eight-shaped regular orbits inside the electron jet, noncrossing regular orbits on the jet flanks, noncrossing Speiser orbits, and nongyrotropic electrons in the downstream of the jet termination region. Properties of a super-Alfvénic outflow jet are attributed to an ensemble of electrons traveling through Speiser orbits. Noncrossing orbits are mediated by the polarization electric field near the electron current layer. The noncrossing electrons are found to be non-negligible in number density. The impact of these new orbits to electron mixing, spatial distribution of energetic electrons, and observational signatures, is presented.

Gravitational waveforms from binary neutron star mergers with high-order WENO schemes in numerical relativity

description: The theoretical modeling of gravitational waveforms from binary neutron star mergers requires precise numerical relativity simulations. Assessing convergence of the numerical data and building the error budget is currently challenging due to the low accuracy of general-relativistic hydrodynamics schemes and to the grid resolutions that can be employed in $(3+1)$-dimensional simulations. In this work, we explore the use of high-order weighted-essentially-nonoscillatory (WENO) schemes in neutron star merger simulations and investigate the accuracy of the waveforms obtained with such methods. We find that high-order WENO schemes can be robustly employed for simulating the inspiral-merger phase and they significantly improve the assessment of the waveform's error budget with respect to finite-volume methods. High-order WENO schemes can be thus efficiently used for high-quality waveforms production, also in future large-scale investigations of the binary parameter space.

Density affects the nature of the hexatic-liquid transition in two-dimensional melting of core-softened systems

description: We find that both continuous and discontinuous hexatic-liquid transitions can happen in the melting of two-dimensional solids of soft-core disks. For three typical model systems, Hertzian, harmonic, and Gaussian-core models, we observe the same scenarios. These systems exhibit reentrant crystallization (melting) with a maximum melting temperature $T_m$ happening at a crossover density $ρ_m$. The hexatic-liquid transition at a density smaller than $ρ_m$ is discontinuous. Liquid and hexatic phases coexist in a density interval, which becomes narrower with increasing temperature and tends to vanish approximately at $T_m$. Above $ρ_m$, the transition is continuous, in agreement with the Kosterlitz-Thouless-Halperin-Nelson-Young theory. For these soft-core systems, the nature of the hexatic-liquid transition depends on density (pressure), with the melting at $ρ_m$ being a plausible transition point from discontinuous to continuous hexatic-liquid transition.
