description: Summary. Laughter occurs in different social situations, is triggered by different stimuli and can go along with a number of affective states. This variability is largely mirrored in natural language that is used to describe laughter: In a study using a lexical approach, more than 1000 different words used to describe laughter were identified. On the basis of this word list, a classification of formal attributes of laughter was defined. Building on these results, the present study investigates whether or not 20 adjectives describing affective and motivational states and that have been used in previous research can be described on the formal aspects of basic parameter (e.g. duration), intensity, sound, uniqueness and regulation. A hierarchical cluster analysis based on data of 81 participants showed that five clusters could be distinguished. Some of these clusters differed substantially in regard to the formal aspects. The results suggest that the dimensions based on the lexical approach are useful to characterize different kinds of laughter and can be used for future research.


Zusammenfassung.  Lachen kommt in unterschiedlichen sozialen Situationen vor, wird von unterschiedlichen Arten von Stimuli ausgelöst und geht mit unterschiedlichen Emotionen einher – dies führt zu einer großen Variabilität von Lachen. Diese Variabilität spiegelt sich in der Sprache wider, die dazu verwendet wird, Lachen zu beschreiben: In der deutschen Sprache fanden sich in einer korpuslinguistischen Analyse mehr als 1000 Wörter, die für eine Beschreibung bzw. Differenzierung verschiedener Arten von Lachen gebraucht wurden. Auf dieser Grundlage konnte eine Klassifikation formaler Aspekte des Lachens entwickelt werden. Aufbauend auf dieser Klassifikation wurde in der vorliegenden Studie untersucht, ob 20 Adjektive, die affektive und motivationale Aspekte von Lachen beschreiben und die bereits vorher in der Forschung verwendet wurden, anhand der Dimensionen basaler Parameter (z.B. Dauer), Intensität, Klang, Einzigartigkeit und Regulation differenziert werden können. Eine hierarchische Clusteranalyse über die Einschätzungen von 81 Erwachsenen hinweg zeigte, dass fünf Cluster identifiziert wurden, die sich zum Teil deutlich in den gewonnenen Dimensionen unterschieden. Diese Ergebnisse weisen darauf hin, dass die über den lexikalischen Ansatz gewonnenen Dimensionen nützlich zur Beschreibung verschiedener Arten des Lachens und zum Einsatz in weiterer Forschung sind.

Probabilistic transient stability studies using the BC Hydro system
Creators: name: Chia, Timothy Kai-Loh
Publisher: name: University of British Columbia
Year: 2009

description: The power utility industry in North America is quickly evolving from a monopolistic environment to a competitive one. Traditional dynamic security assessment methods and tools which have served the industry well in the past cannot provide the risk analysis needed to extract more value out of existing assets. BC Hydro's current deterministic practice is to study the "worst case", where all faults are assumed to be 3$ bus faults with unsuccessful reclosing, at a load factor of 100%. A review of historical fault data from BC Hydro's 500 kV system over the past 20 years has shown these assumptions do not reflect the true nature of the power system. However, they are in place to ensure that minimum operating reliability mandated by regulatory agencies are met. Based on historical statistics, the probabilistic states of load factor, fault type, fault location, fault clearing, and automatic reclosing were applied to a generation rejection study on the Peace system and a transfer limit study on the Columbia system. For each study, 1000 simulations were carried out on a full model of the BC Hydro interconnected system, with the probabilistic states chosen via Monte Carlo techniques. The results were quantified using a BC Hydro developed transient stability assessment module in conjunction with a commercial load flow and dynamic simulation package (PTI's PSS/E). The results showed that BC Hydro's existing deterministic criteria are very conservative, with a risk of instability between 0% and 0.2% in the Peace case and 0.1% in the Columbia case. Although the risk of instability was calculated as 0% for the Peace case, this an approximation error due to the number of samples used. The studies also revealed that the deterministic criteria does not always correspond to the "worst case" as normally assumed. An analysis of the effectiveness of each probabilistic factor considered showed that fault type and successful/unsuccessful reclosing were the more significant factors, while fault location on the line was the least significant. This research has shown that considering the probabilistic nature of the power system in dynamic security assessment can lead to less remedial actions and increased transfer limits.
Gätschenberger über das „Gegebene“ und Carnaps „Aufbau“

Publisher: name: Zeitschrift für Semiotik

description: In seinem Aufbau kritisiert Carnap Gätschenbergers Vorstellung von der Unmöglichkeit einer reinen Sprache des „Gegebenen“. Für Carnap ist das Gegebene ein Gegenstand und die Erkenntnis die Konstruktion („Konstitution“) der Gegenstände aus dem Gegebenen. Der Begriff des Gegebenen ist entscheidend auch für die als Alternative zur traditionellen Erkenntniskritik formulierte semiotische Theorie Gätschenbergers. Gätschenberger betrachtet das Gegebene oder jedes einzelne Erlebnis als natürliches Symbol, das einen Gegenstand setzt. Der Gegenstand kann durch die Wirkungen des Erlebnisses und insbesondere Handlungen, die das Erlebnis auslöst, identifiziert werden. Das Gegebene kann sich dank seiner symbolischen Natur auf jeden möglichen Gegenstandsbereich beziehen und fungiert als Fundament der Erkenntnis. Gätschenberger glaubt, dass sich diese Eigenschaften des Gegebenen vor allem in dessen „demonstrierender“ Funktion in Bezug auf Satzsysteme zeigen. Ich behaupte, dass diese Annahme problematisch ist und dass Gätschenbergers Auffassung des Gegebenen als Symbol sie nicht rechtfertigt. Carnaps Begriff des Gegebenen kann als eine Lösung dieses und einiger anderer Probleme der Theorie Gätschenbergers angesehen werden.

description: The manuscript discusses how to incorporate random effects for quantile regression models for clustered data with focus on settings with many but small clusters. The paper has three contributions: (i) documenting that existing methods may lead to severely biased estimators for fixed effects parameters; (ii) proposing a new two-step estimation methodology where predictions of the random effects are first computed {by a pseudo likelihood approach (the LQMM method)} and then used as offsets in standard quantile regression; (iii) proposing a novel bootstrap sampling procedure in order to reduce bias of the two-step estimator and compute confidence intervals. The proposed estimation and associated inference is assessed numerically through rigorous simulation studies and applied to an AIDS Clinical Trial Group (ACTG) study.

description: Building towards a more covariant approach to canonical classical and quantum gravity we outline an approach to constrained dynamics that de-emphasizes the role of the Hamiltonian phase space and highlights the role of the Lagrangian phase space. We identify a "Lagrangian one-form" to replace the standard symplectic one-form, which we use to construct the canonical constraints and an associated constraint algebra. The method is particularly useful for generally covariant systems and systems with a degenerate canonical symplectic form, such as Einstein Cartan gravity, to which we apply the method explicitly. We find that one can demonstrate the closure of the constraints without gauge fixing the Lorentz group or introducing primary constraints on the phase space variables. Finally, using geometric quantization techniques, we briefly discuss implications of the formalism for the quantum theory.

description: A first-principles-based model is developed to investigate the influence of lead vacancies on the properties of relaxor ferroelectric Pb(Sc1/2Nb1/2)O3 (PSN). Lead vacancies generate large, inhomogeneous, electric fields that reduce barriers between energy minima for different polarization directions. This naturally explains why relaxors with significant lead vacancy concentrations have broadened dielectric peaks at lower temperatures, and why lead vacancies smear properties in the neighborhood of the ferroelectric transition in PSN. We also reconsider the conventional wisdom that lead vacancies reduce the magnitude of dielectric response.

description: The supernova remnant (SNR) G150.3+4.5 was recently discovered in the radio band; it exhibits a shell-like morphology with an angular size of $\sim 3^{\circ}$, suggesting either an old or a nearby SNR. Extended $γ$-ray emission spatially coincident with the SNR was reported in the Fermi Galactic Extended Source Catalog, with a power-law spectral index of $Γ$ = 1.91 $\pm$ 0.09. Studying particle acceleration in SNRs through their $γ$-ray emission is of primary concern to assess the nature of accelerated particles and the maximum energy they can reach. Using more than ten years of Fermi-LAT data, we investigate the morphological and spectral properties of the SNR G150.3+4.5 from 300 MeV to 3 TeV. We use the latest releases of the Fermi-LAT catalog, the instrument response functions and the Galactic and isotropic diffuse emissions. We use ROSAT all-sky survey data to assess any thermal and nonthermal X-ray emission, and we derive minimum and maximum distance to G150.3+4.5. We describe the $γ$-ray emission of G150.3+4.5 by an extended component which is found to be spatially coincident with the radio SNR. The spectrum is hard and the detection of photons up to hundreds of GeV points towards an emission from a dynamically young SNR. The lack of X-ray emission gives a tight constraint on the ambient density $n_0 \leq 3.6 \times 10^{-3}$ cm$^{-3}$. Since G150.3+4.5 is not reported as a historical SNR, we impose a lower limit on its age of $t$ = 1 kyr. We estimate its distance to be between 0.7 and 4.5 kpc. We find that G150.3+4.5 is spectrally similar to other dynamically young and shell-type SNRs, such as RX J1713.7$-$3946 or Vela Junior. The broadband nonthermal emission is explained with a leptonic scenario, implying a downstream magnetic field of $B = 5$ $μ$G and acceleration of particles up to few TeV energies.
Multiphoton Coherence of Thermal Light
Creators: name: Zhou, Yu
Publisher: name: Maryland Shared Open Access Repository
Year: 2010

description: Multiparticle interference is one of the most surprising consequences of quantum mechanics. In quantum theory, a interference happens between different, yet indistinguishable probability amplitudes. Probability amplitudes can be nonlocal when they are connected with systems including several particles. The interference between these nonlcoal probability amplitudes sometimes can only be understood by quantum theory. In this dissertation, the multiphoton coherence of thermal light is studied, theoretically and experimentally, as the consequences of interference between nonlcoal probability amplitudes. The study showed that the higher order correlation functions of thermal light had higher contrast compared with the lower order correlation functions. For example, the contrast of the Nth order correlation function of thermal light can reach N!:1. This is because in higher order correlation functions there are more cross terms from interference contribute to the correlation peak.  In this dissertation, the high contrast property is employed to increase the contrast of thermal light ghost imaging. An experiment showed that the contrast of the third order ghost image is significantly improved compared with that of the second order ghost image.

description: Nonlinear phenomena in optical fibers have been attracting considerable attention because of the rapid growth   of the fiber optics communication industry. The increasing demand in internet use and the expansion of telecommunications in the developing world have triggered the need for high capacity and ultra-fast communication devices and also the need to increase the number of transmission channels in the fibers. Wavelength Division Multiplexing (WDM) and Dense Wavelength Division Multiplexing (DWDM) systems are capable of transmitting large volumes of data at very high rates into huge numbers of optical transmission channels. This ability is limited by the gain bandwidth of Silica based fiber optics amplifiers already installed in the communication networks. Tellurite based fiber amplifiers offer the necessary bandwidth for amplification of WDM and DWDM channels.    To investigate the nonlinear properties of the optical fibers in this research, we used a 10 picoseconds pulse width passively mode-locked Nd:Vanadate ( Nd:YVO4) laser operating at 1342nm with a repetition rate of 76 MHz. We accurately measured the nonlinear refractive index of single mode silica fibers utilizing the Induced Grating Autocorrelation (IGA) technique. IGA technique was extended furthermore to study nonlinear effects in multimode fibers, and for the first time, we successfully measured the nonlinear refractive index (n2) of a multimode silica fiber.  Confident of the ability of IGA technique for determining n2 of multimode silica fibers, we measured the nonlinear refractive index of multimode Tellurite glass fibers with length as short as 0.5 meter.  The goal of this work is to provide accurate and reliable information on the nonlinear optical properties of Tellurite glass fibers, novel fibers with promising future for developing ultrafast and high transmission capacity communication devices.

description: We present a complete calculation of the structure of liquid $^4$He confined to a concave nanoscopic wedge, as a function of the opening angle of the walls. This is achieved within a finite-range density functional formalism. The results here presented, restricted to alkali metal substrates, illustrate the change in meniscus shape from rather broad to narrow wedges on weak and strong alkali adsorbers, and relate this change to the wetting behavior of helium on the corresponding planar substrate. As the wedge angle is varied, we find a sequence of stable states that, in the case of cesium, undergo one filling and one emptying transition at large and small openings, respectively. A computationally unambiguous criterion to determine the contact angle of $^4$He on cesium is also proposed.

description: We introduce a statistical and linear response theory of selective conduction in biological ion channels with multiple binding sites and possible point mutations. We derive an effective grand-canonical ensemble and generalised Einstein relations for the selectivity filter, assuming strongly coordinated ionic motion, and allowing for ionic Coulomb blockade. The theory agrees well with data from the KcsA K$^+$ channel and a mutant. We show that the Eisenman relations for thermodynamic selectivity follow from the condition for fast conduction and find that maximum conduction requires the binding sites to be nearly identical.

description: State of Matter bietet einen partizipativen und begreifbaren Umgang mit abstrakten und schwer zugänglichen Phänomenen. Zentraler Grundgedanke ist die Möglichkeit der Übersetzung und Verwandlung von aktuell abstrakten und nicht greifbaren Phänomenen, Prozessen und Themen in eine physische Erfahrbarkeit. State of Matter knüpft hier an das Konzept des erfahrungsbasierten Verstehens und Lernens von Lakoff und Johnson an und erzeugt Verständnis für neue Technologien durch Sinneswahrnehmung, Körperbewegung sowie der direkten Interaktion mit der physischen und sozialen Umwelt. Durch physische Interaktionskonzepte und den Umgang mit scheinbar einfachen Materialien wird ein tastender Zugang zu den unterschiedlichen komplexen Feldern und Technologien ermöglicht. Im Dialog von physischer Erfahrung und Geist entsteht so Raum für Kreativität.


In diesem Artikel wird der Fokus eines handlungsbezogenen State of Matter Ansatzes an der Schnittstelle zum Digitalen genauer betrachtet. Durch das Nutzbarmachen geeigneter physischer Materialqualitäten in erfahrungsbasierten Übungen zu digitalen Prozessen, die heute zum einen stark vernetzte Vereinfachungen im Alltag und zum anderen auch starke Abstraktion mit sich bringen, erzeugt State of Matter Kristallisationspunkte in der Erfahrbarkeit individueller Möglichkeitsräume. Hierbei wird darauf geachtet, dass diese Erfahrbarkeit hinzugezogene digitale Methoden und Werkzeuge zur weitreichenden Analyse von gesellschaftlichen und technologischen Entwicklungsprozessen einschließt. Somit wird das Workshopformat State of Matter in diesem Artikel als neuartiges Kommunikations- und Gestaltungsformat und als Bindeglied im Digitalen verstanden.

description: The concept of nonlinear modes is useful for the dynamical characterization of nonlinear mechanical systems. While efficient and broadly applicable methods are now available for the computation of nonlinear modes, nonlinear modal testing is still in its infancy. The purpose of this work is to overcome its present limitation to conservative nonlinearities. Our approach relies on the recently extended periodic motion concept, according to which nonlinear modes of damped systems are defined as family of periodic motions induced by an appropriate artificial excitation that compensates the natural dissipation. The particularly simple experimental implementation with only a single-point, single-frequency, phase resonant forcing is analyzed in detail. The method permits the experimental extraction of natural frequencies, modal damping ratios and deflection shapes (including harmonics), for each mode of interest, as function of the vibration level. The accuracy, robustness and current limitations of the method are first demonstrated numerically. The method is then verified experimentally for a friction-damped system. Moreover, a self-contained measure for estimating the quality of the extracted modal properties is investigated. The primary advantages over alternative vibration testing methods are noise robustness, broad applicability and short measurement duration. The central limitation of the identified modal quantities is that they only characterize the system in the regime near isolated resonances.

description: As the dominant anthropogenic greenhouse gas, carbon dioxide (CO2), represents an important component of climate change (IPCC 2007). Owing to burning of fossil fuels and deforestation, atmospheric CO2 concentrations have increased over 110 parts-per-million by volume (ppmv) from 270 ppmv to 380 ppmv since the dawn of the Industrial Revolution.  Understanding of the spatial distribution of the sources and sinks of atmospheric CO2 is necessary not only to predict the future atmospheric abundances but also their effect on future climate. Although designed for deriving high precision temperature and moisture profiles, NASA's Atmospheric InfraRed Sounder (AIRS) IR measurements include broad vertical sensitivity (between 3 and 10 km) to atmospheric CO2 variations. Coupled with AIRS' broad swath pattern and a technique referred to as ""cloud-clearing"" these measurements enable daily global spatial coverage. Nevertheless, AIRS' ability to determine the spatial distribution of carbon dioxide (CO2) is strongly dependent on its ability to separate the radiative effects of CO2 from temperature not to mention measurement uncertainties due to clouds and other geophysical variables such as moisture and ozone. This research presents a thorough investigation into the temporal and spatial scales that the AIRS can separate temperature (and other geophysical variables) from CO2. Through our detailed understanding of the way satellites view the Earth's atmosphere, we have developed an algorithm capable of retrieving global middle-to-upper tropospheric CO2 concentrations in all-weather conditions with total uncertainties ranging between 1 to 2 ppmv.  From a radiative perspective, roughly equivalent to 30 mK to 60 mK, 1 to 2 ppmv, is an awesome feat for a space-borne sensor. Necessary for the remarkable performance of this algorithm, we developed methodologies capable of separating the radiative effect of CO2 variability from temperature, improved the fast rapid transmittance algorithm for AIRS, and derived algorithm diagnostics that provide the case-dependent skill of AIRS algorithms for temperature and all other constituents (e.g. H2O, O3, CO, CH4, and CO2) from theoretical considerations. As a result, the 1 to 2 ppmv uncertainties match extremely well with simulation; experiments performed before validation experiments had collected data and the retrieval algorithm was still in its infancy.

description: Quantum cascade lasers (QCLs) are semiconductor lasers based on intersubband transitions and resonant tunneling, emitting mid- to far-infrared light. This dissertation used femtosecond (fs) mid-IR pulses generated by difference-frequency generation (DFG) to investigate the ultrafast carrier dynamics and nonlinear effects in QCLs. In this work, the carrier dynamics of high wall-plug efficiency designed QCLs were investigated utilizing fs mid-IR degenerate pump-probe technique. We observed ultrafast gain recovery within the first 200 fs due to the thin injector barrier inducing fast electron resonant tunneling, fast depletion from lower lasing level by two-phonon resonance design, and relaxation from the continuum region. The observed gain recovery oscillation is interpreted as electrons excited by incoming photons up to higher subbands or continuum region then falling into the next periods of active region so as to dramatically increase the gain on a short time scale. Later, slower gain recovery (2-3 picoseconds) is observed by electron transport through the injector region of the superlattice structure and tunneling into the next period of active region. Another ultraslow recovery component (hundreds of picoseconds) is likely caused by the electron heating and cooling effects as well as the collection of electrons into the lower subbands in real space and compensated by the external bias supply. The latter contribution is support by the observed positive photoconductivity with increased current and decreased voltage across the QCL. We studied the SHG signal generated by focusing different polarizations (TE and TM modes) fs mid-IR pulses into the QCLs' active core. SHG due to intersubband transitions is observed when the pump is TM polarized (SHGTM). The measured SHGTM spectrum narrows when the bias across the QCL increases due to the electron population re-distribution and subband realignment. The expected quadratic dependence of the SHGTM with mid-IR pump power is observed, but saturates at higher pump powers. The observed SHG pumped by TE polarized fs mid-IR pulses (SHGTE) is most likely generated by the bulk nonlinearity of the InP substrate. The second order nonlinearity for SHGTE is also confirmed, without observing the saturation. We estimated linear-to-nonlinear power conversion efficiency for both SHGTM and SHGTE.

description: We observed the high-mass star-forming region G335.579-0.292 with the Atacama Large Millimeter/submillimeter Array (ALMA) at 226 GHz with an angular resolution of 0.3'' ($\sim 1000$ au resolution at the source distance). G335.579-0.292 hosts one of the most massive cores in the Galaxy (G335-MM1). The continuum emission shows that G335-MM1 fragments into at least five sources, while molecular line emission is detected in two of the continuum sources (ALMA1 and ALMA3). We found evidence of large and small scale infall in ALMA1 revealed by an inverse P-Cygni profile and the presence of a blue-shifted spot at the center of the first moment map of the CH$_3$CN emission. In addition, hot gas expansion in the innermost region is unveiled by a red-shifted spot in the first moment map of HDCO and (CH$_3$)$_2$CO (both with $E_u > 1100$ K). Our modeling reveals that this expansion motion originates close to the central source, likely due to reversal of the accretion flow induced by the expansion of the HII region, while infall and rotation motions originate in the outer regions. ALMA3 shows clear signs of rotation, with a rotation axis inclination with respect to the line of sight close to $90^\circ$, and a system mass (disk + star) in the range of 10-30 M$_\odot$.

description: Steigende Bedarfe, kürzer werdende Produktlebenszyklen und zunehmende Variantenvielfalt führen zu einer erhöhten Komplexität in Produktionsprozessen. Eine Möglichkeit, diesen Herausforderungen zu begegnen, ist die Kombination manueller und automatisierter Arbeit in Form einer instruktiven Mensch-Roboter-Kollaboration (iMRK). Ein Assistenzroboter erhält Instruktionen, wo und wie die nächsten Produktionsschritte durchzuführen sind. Der Roboter wird von einem Mitarbeiter flexibel für Paralleltätigkeiten eingesetzt, ohne die ursprüngliche Roboterprogrammierung anzupassen. Notwendig dafür sind jedoch gebrauchstaugliche Mensch-Roboter-Schnittstellen (MRS). Gestaltungskonzepte für gebrauchstaugliche iMRK an einem Produktionsarbeitsplatz sind aktuell weder in der Wissenschaft noch in der Praxis zu finden. Verortet im Forschungsparadigma der gestaltungsorientierten Forschung präsentiert der Beitrag die Grundlagen und Voraussetzungen zur Umsetzung einer iMRK. Diese dienen als Basis für einen theoriegeleiteten Leitfaden zur nutzerzentrierten Gestaltung solcher Systeme. Die strukturierte und methodisch ausgestaltete Vorgehensweise unterstützt Planer und Entwickler von Produktionsassistenzsystemen in der industriellen Automobilproduktion. Der Beitrag zeigt die theoriegeleite Konzeption als Grundlage für die Instanziierung des Leitfadens zur Entwicklung eines Assistenzroboters in der Anwendungsdomäne.

description: Using the complete numerical solution of a time-dependent three-dimensional mean-field model we study the Josephson oscillation of a superfluid Fermi gas (SFG) at zero temperature formed in a combined axially-symmetric harmonic plus one-dimensional periodic optical-lattice (OL) potentials after displacing the harmonic trap along the axial OL axis. We study the dependence of Josephson frequency on the strength of the OL potential. The Josephson frequency decreases with increasing strength as found in the experiment of Cataliotti et al. [Science 293 (2001) 843] for a Bose-Einstein condensate and of the experiment of Pezze et al. [Phys. Rev. Lett. 93 (2004) 120401] for an ideal Fermi gas. We demonstrate a breakdown of Josephson oscillation in the SFG for a large displacement of the harmonic trap. These features of Josephson oscillation of a SFG can be tested experimentally.

description: Atomic layer deposition (ALD) is a cyclic growth process that is distinguished by a self-limiting, two-step surface reaction that results in precise growth control and high quality, conformal thin films.  Due to the continuous downscaling of MOSFET devices, a large interest has recently developed in the ALD of high- ? dielectric materials as gate oxide layers on Si and III-V substrates.  The ALD of HfO2 is an established process; however, there is still controversy over the initial growth mechanisms on differently prepared Si surfaces.  This motivated a comparison of the nucleation stage of HfO2 films grown on OH- (Si-OH) and H-terminated (Si-H) Si(100) surfaces. Two different ALD chemistries are investigated, including tetrakis[ethylmethylamino]hafnium (Hf[N(CH3)(C2H5)]4), abbreviated as TEMAH, and tetrakis[dimethylamino]hafnium (Hf[N(CH3)2]4, abbreviated as TDMAH.  H2O is used as the oxidizing precursor. Deposition temperatures of 250-275°C result in a linear growth per cycle of 1 Å/cycle.  Techniques including Rutherford backscattering spectrometry (RBS), X-ray photoelectron spectroscopy (XPS), spectroscopic ellipsometry (SE), and transmission electron microscopy are used to examine the film interface and initial film growth.  HfO2 films are also subjected to post-deposition anneals, and the film morphology is examined with X-ray diffraction, Fourier transform infrared spectroscopy and atomic force microscopy.  GaAs MOSFET devices have long proven elusive due to the lack of a stable native oxide.  Recent research into high- ? dielectric materials for use in Si-based devices has presented many new options for insulating layers on GaAs.  HfO2 growth on GaAs(100) from a TDMAH+H2O ALD process is studied here.  Three different GaAs surface treatments are examined, including buffered oxide etch (BOE), NH4OH, and a simple acetone/methanol wash (to retain the native oxide surface).  Initial HfO2 growth on these surfaces is characterized with RBS and SE.  The interfacial composition is examined with XPS both before and after HfO2 deposition.  Also, an interesting native oxide 'consumption' mechanism is investigated, which involves the dissolution of the GaAs native oxide during the ALD process.  This project presents the first detailed study of HfO2 growth on GaAs with the TDMAH/H2O ALD chemistry, providing XPS, RBS and SE characterization of early film growth.

description: The efforts of this research have been directed towards improving both the heralding efficiency and heralding rates of a high performance fiber-coupled single photon source based on an ultrafast pulsed beam-like Type-II parametric down conversion (PDC) source.   Entangled photons generated from PDC are inherently broadband (many frequencies) and exit the nonlinear crystal at varying angles (different directions).  This makes coupling the photons into single-mode fibers, a desirable feature for quantum computing, difficult.  In response to these difficulties we have explored applying multi-layered thin film broadband anti-reflection coatings onto the ends of single-mode fibers using the technique of RF Planar Magnetron Sputtering in an effort to increase the coupling efficiency of the beam-like down converted photons.  In addition, we have explored theoretically the broadband nature of novel phase matching geometries to increase heralding rates and minimize photon losses.  With the ability to tailor coupling fibers to various down conversion sources we hope to increase both the heralding efficiency and heralding rate to levels needed for a broad range of future experiments.

Publisher: name: aw&I Conference
Year: 2018

description: Interpersonale Kompetenzen sind im IT-Bereich sehr wichtig, da in diesem Sektor viele Teams und Kleingruppen gebildet werden. Das PeerLeaders-Konzept, bei dem höhere Semester Kommilitonen im Basisstudium unterstützen, festigt den Studienerfolg durch gruppendynamische Prozesse und verbessert Verantwortungsübernahme, Empathiefähigkeit und Networking. Da die Peer-Gruppen für jedes Modul neu gebildet werden, ergibt sich automatisch ein Netzwerk zwischen den Studierenden.


Die Grundidee basiert darauf, dass Studierende höherer Semester diejenigen aus den ersten Semestern im Basisstudium unterstützen. Die Peers erhalten ECTS-Punkte, da das Programm im Rahmen des Seminars „Kommunikations- und Führungstechniken“ stattfindet. Die Unterstützung kann sowohl organisatorisch sowie fachlich erfolgen. Durch die fachliche Unterstützung setzen sich die Studierenden erneut mit dem Stoff aus dem Basisstudium auseinander.

description: Quantum computing is an emerging field of science which will eventually lead us to new and powerful logic devices with capabilities far beyond the limits of current transistor-based technology. There are certain types of problems which quantum computers can solve fundamentally faster than the tradition digital computers. There are quantum algorithms which require both superposition and entanglement (e.g. Shor algorithm). But neither the Grover algorithm nor the very first quantum algorithm due to Deutsch and Jozsa need entanglement. Is it possible to utilize classical wave superposition to speedup database search? This interesting question was analyzed by S. Lloyd. It was concluded that classical devices that rely on wave interference may provide the same speedup over classical digital devices as quantum devices. There were several experimental works using optical beam superposition for emulating Grover algorithm. It was concluded that the use of classical wave superposition comes with the cost of exponential increase of the resources. Since then, it is widely believed that the use of classical wave superposition for quantum algorithms is inevitably leading to an exponential resources overhead (number of devices, power consumption, precision requirements). In this work, we describe a classical Oracle machine which utilizes classical wave superposition for database search and data processing. We present experimental data on magnetic database search using spin wave superposition. The data show a fundamental speedup over the digital computers without any exponential resource overhead. We argue that in some cases the classical wave-based approach may provide the same speedup in database search as quantum computers.
