Efectos electro–ópticos no lineales y formación de estructuras en sistemas de pozos cuánticos
Creators: name: Velasco, Carlos A.
Publisher: name: Zenodo
Year: 1999

description: Las heteroestructuras de materiales semiconductores tienen unas propiedades ópticas peculiares debidas al fuerte acoplamiento entre los efectos ópticos con los efectos electrostáticos. Entre los posibles resultados se cuentan la aparición de biestabilidad óptica

intrínseca y sus consecuencias, tales como la formación de estructuras espaciales.

Desde hace más de diez años, se ha desarrollado todo un campo de investigación de estos materiales y sus propiedades ópticas. Podemos destacar, entre los ejemplos recientes, heteroestructuras de pozos cuánticos fotoexcitados sujetos a la acción de un campo eléctrico externo, superredes de InAlAs/InGaAs encastradas en uniones p-i-n, dispositivos de efecto electro-óptico autosostenido (SEEDs, Self-Electro--optical Effect Devices), y efecto Stark bajo confinamiento cuántico en pozos cuánticos de nitruros-tipo III (GaN, AlN, InN, y todos sus compuestos derivados).

En esta memoria analizamos en detalle los procesos de creación y formación de estructuras de plasma electrón - hueco en sistemas de pozos cuánticos (de GaAs), fotoexcitados con una iluminación uniforme, y en un campo eléctrico constante. A principios de los años 90, el Profesor R. Merlin y su grupo obtuvieron una serie de resultados experimentales en este tipo de heteroestructuras que demostraron la existencia de biestabilidad electro-óptica. Es posible entonces prever la creación de estructuras de plasma espaciales no uniformes perpendiculares a la dirección de crecimiento. Nuestro análisis de un modelo matemático consistente con los resultados experimentales y la física subyacente justificará esta hipótesis y explicará cuáles son las posibles estructuras estables.

description: This thesis examines Samuel Beckett’s exploration of the art of radio in his six radio plays from 1957 onwards, from a range of aesthetic approaches and literary-theoretical viewpoints. In doing so, I aim to foreground the literary merits of the radio drama and of Beckett’s distinctive aesthetic use of radio – an aspect of his work which is still relatively neglected. At the same time I move beyond internal literary study of these works to situate both them and the medium of radio itself in their wider cultural and historical contexts, particularly the Second World War. Chapter One evokes three local contexts for the study of Beckett’s radio plays: the development of radio drama at the BBC prior to 1957, early European avant-garde radio theories, particularly those of Futurism and Surrealism, and Beckett’s own early fiction, which is preoccupied with themes of voice, silence and listening which radio explores further. Chapter Two examines psychoanalytic theories of trauma, and trauma studies in the humanities more generally, for what they can reveal to us about both the literary form and psychic content of the radio plays. The particular traumas mapped out in these texts are then related to that general matrix of trauma for Beckett, the Second World War. Chapter Three draws on the work of Michel Foucault, whose concepts of discipline, confinement and panopticon are applied to Rough for Radio II. Chapter Four studies local instances of both silence and music in the radio drama, but also examines the way in which these two Beckettian motifs become a general programme towards minimalism that explains the overall trajectory of the six radio plays. Chapter Five seeks a way beyond the debate about whether Beckett is a modernist or postmodernist by exploring the concept of “late modernism” in relation to his radio drama.

description: Scaling properties of galaxy cluster observables with mass provide central insights into the processes shaping clusters. Calibrating proxies for cluster mass will be crucial to cluster cosmology with upcoming surveys like eROSITA and Euclid. The recent Planck results led to suggestions that X-ray masses might be biased low by $\sim\!40$ %, more than previously considered. We extend the direct calibration of the weak lensing -- X-ray mass scaling towards lower masses (as low as $1\!\times\!10^{14}\,\mathrm{M}_{\odot}$) in a sample representative of the $z\!\sim\!0.4$--$0.5$ population. We investigate the scaling of MMT/Megacam weak lensing (WL) masses for $8$ clusters at $0.39\!\leq\!z\!\leq\!0.80$ as part of the \emph{400d} WL programme with hydrostatic \textit{Chandra} X-ray masses as well as those based on the proxies, e.g. $Y_{\mathrm{X}}\!=\!T_{\mathrm{X}}M_{\mathrm{gas}}$. Overall, we find good agreement between WL and X-ray masses, with different mass bias estimators all consistent with zero. Subdividing the sample, we find the high-mass subsample to show no significant mass bias while for the low-mass subsample, there is a bias towards overestimated X-ray masses at the $\sim\!2σ$ level for some mass proxies. The overall scatter in the mass-mass scaling relations is surprisingly low. Neither observation can be traced back to the parameter settings in the WL analysis. We do not find evidence for a strong ($\sim\!40$ %) underestimate in the X-ray masses, as suggested to reconcile Planck cluster counts and cosmological constraints. For high-mass clusters, our measurements are consistent with studies in the literature. The mass dependent bias, significant at $\sim\!2σ$, may hint at a physically different cluster population (less relaxed clusters with more substructure and mergers); or it may be due to small number statistics.

description: The young magnetically active solar-like stars are efficient generators of ionizing radiation in the form of X-ray and extreme-UV (EUV) flux, stellar wind, and eruptive events. These outputs are the critical factors affecting atmospheric escape and chemistry of (exo)planets around active stars. While X-ray fluxes and surface magnetic fields can be derived from observations, the EUV emission, and wind mass fluxes, coronal mass ejections and associated stellar energetic particle events cannot be directly observed. Here, we present the results of a three-dimensional magnetohydrodynamic (MHD) model with inputs constrained by spectropolarimetric data, Hubble Space Telescope/STIS far-UV and X-ray data, and stellar magnetic maps reconstructed at two epochs separated by 11 months. The simulations show that over the course of the year the global stellar corona had undergone a drastic transition from a simple dipole-like to a tilted dipole with multipole field components and thus provided favorable conditions for corotating interaction regions (CIRs) that drive strong shocks. The dynamic pressures exerted by CIRs are 1300 times larger than those observed from the Sun and can contribute to the atmospheric erosion of early Venus, Earth, Mars, and young Earth-like exoplanets. Our data-constrained MHD model provides the framework to model coronal environments of G-M planet-hosting dwarfs. The model outputs can serve as a realistic input for exoplanetary atmospheric models to evaluate the impact of stellar coronal emission, stellar winds, and CIRs on their atmospheric escape and chemistry that can be tested in the upcoming James Webb Space Telescope and ground-based observations.

description: A new ocean wave/sea-ice interaction model is proposed that simulates how a directional wave spectrum evolves as it travels through an arbitrary finite array of circular ice floes, where wave/ice dynamics are entirely governed by wave scattering effects. The model is applied to characterise the wave reflection and transmission properties of a strip of ice floes, such as an ice edge band. A method is devised to extract the reflected and transmitted directional wave spectra produced by the array. The method builds upon an integral mapping from polar to Cartesian coordinates of the scattered wave components. Sensitivity tests are conducted for a row of floes randomly perturbed from a regular arrangement. Results for random arrays are generated using ensemble averaging. A realistic ice edge band is then reconstructed from field experiments data. Simulations show a good qualitative agreement with the data in terms of transmitted wave energy and directional spreading. In particular, it is observed that short waves become isotropic quickly after penetrating the ice field.

The calculations have been performed with JUN45 and jj44b effective interactions that have been proposed for use in the $f_{5/2}$, $p_{3/2}$, $p_{1/2}$, $g_{9/2}$ model space for both protons and neutrons. Reasonable agreement between experimental and calculated values are obtained. This work will add more information to previous study by projected shell model [Eur. Phys. J.

description: An extraordinary focusing property of a parabolic mirror for ultracold neutrons in the presence of the gravitational field was first reported by A. Steyerl and co-authors. It was shown that all neutrons emitted from the focus of the mirror will be reflected back upon the same focus point passing, in between, a point of return in the gravitational field. The present note offers a complementary geometric proof of this feature and discusses some implications.

description: We review how the paraxial approximation naturally leads to a hydrodynamic description of light propagation in a Kerr nonlinear medium analogous to the Gross-Pitaevskii equation for the temporal evolution of the order parameter of a superfluid. The main features of the many-body collective dynamics of these fluids of light in a propagating geometry are discussed: Generation and observation of Bogoliubov sound waves on top of the fluid is first described. Experimentally accessible manifestations of superfluidity are then highlighted. Perspectives in view of realizing analog models of gravity are finally given.

description: We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted for 870um continuum observation with ALMA. The high angular resolution of the ALMA imaging allows secure counterparts to be identified in the CANDELS multiband dataset. The CANDELS data provide deep photometric data from UV through near-infrared wavelengths. Using synthetic spectral energy distributions, we derive photometric redshifts, stellar masses, extinction, ages, and the star formation history. The redshift range is z=1.65-4.76, with two of the galaxies located at z>4. Two SMG counterparts have stellar masses 2-3 orders of magnitude lower than the rest. The remaining SMG counterparts have stellar masses around 1x10^11 Msun. The stellar population in the SMGs is typically older than the expected duration of the submillimeter phase, suggesting that the star formation history of submillimeter galaxies is more complex than a single burst. Non-parametric morphology indices suggest that the SMG counterparts are among the most asymmetric systems compared with galaxies of the same stellar mass and redshift. The HST images shows that 3 of the SMGs are associated with on-going mergers. The remaining counterparts are isolated. Estimating the dust and molecular gas mass from the submm fluxes, and comparing with our stellar masses shows that the molecular gas mass fraction of SMGs is ~28% and that the final stellar mass is likely to be (1-2)x10^11 Msun.

description: The performance of audio source separation from underdetermined convolutive mixture assuming known mixing filters can be significantly improved by using an analysis sparse prior optimized by a reweighting l1 scheme and a wideband datafidelity term, as demonstrated by a recent article. In this letter, we show that the performance can be improved even more significantly by exploiting a low-rank prior on the source spectrograms.We present a new algorithm to estimate the sources based on i) an analysis sparse prior, ii) a reweighting scheme so as to increase the sparsity, iii) a wideband data-fidelity term in a constrained form, and iv) a low-rank constraint on the source spectrograms. Evaluation on reverberant music mixtures shows that the resulting algorithm improves state-of-the-art methods by more than 2 dB of signal-to-distortion ratio.

description: Fish and other aquatic foods (blue foods) present an opportunity for more sustainable diets1,2. Yet comprehensive comparison has been limited due to sparse inclusion of blue foods in environmental impact studies3,4 relative to the vast diversity of production5. Here we provide standardized estimates of greenhouse gas, nitrogen, phosphorus, freshwater and land stressors for species groups covering nearly three quarters of global production. We find that across all blue foods, farmed bivalves and seaweeds generate the lowest stressors. Capture fisheries predominantly generate greenhouse gas emissions, with small pelagic fishes generating lower emissions than all fed aquaculture, but flatfish and crustaceans generating the highest. Among farmed finfish and crustaceans, silver and bighead carps have the lowest greenhouse gas, nitrogen and phosphorus emissions, but highest water use, while farmed salmon and trout use the least land and water. Finally, we model intervention scenarios and find improving feed conversion ratios reduces stressors across all fed groups, increasing fish yield reduces land and water use by up to half, and optimizing gears reduces capture fishery emissions by more than half for some groups. Collectively, our analysis identifies high-performing blue foods, highlights opportunities to improve environmental performance, advances data-poor environmental assessments, and informs sustainable diets.
Totally asymmetric simple exclusion process with a time-dependent boundary: interaction between vehicles and pedestrians at intersections

description: Interaction between vehicles and pedestrians is seen in many areas such as crosswalks and intersections. In this paper, we study a totally asymmetric simple exclusion process with a bottleneck at a boundary caused by an interaction. Due to the time-dependent effect originating from the speed of pedestrians, the flow of the model varies even if the average hopping probability at the last site is the same. We analyze the phenomenon by using two types of approximations: (2+1)-cluster approximation and isolated rarefaction wave approximation. The approximate results capture intriguing features of the model. Moreover, we discuss the situation where vehicles turn right at the intersection by adding a traffic light at the boundary condition. The result suggests that pedestrian scrambles are valid to eliminate traffic congestion in the right turn lane.

description: We consider the initial energy density in the transverse plane of a high energy nucleus-nucleus collision as a random field $ρ(\x)$, whose probability distribution $P[ρ]$, the only ingredient of the present description, encodes all possible sources of fluctuations. We argue that it is a local Gaussian, with a short-range 2-point function, and that the fluctuations relevant for the calculation of the eccentricities that drive the anisotropic flow have small relative amplitudes. In fact, this 2-point function, together with the average density, contains all the information needed to calculate the eccentricities and their variances, and we derive general model independent expressions for these quantities. The short wavelength fluctuations are shown to play no role in these calculations, except for a renormalization of the short range part of the 2-point function. As an illustration, we compare to a commonly used model of independent sources, and recover the known results of this model.
An accurate integral equation method for simulating multi-phase Stokes flow

Publisher: name: arXiv
Year: 2014
Subjects: subject: Numerical Analysis (math.NA)

description: We introduce a numerical method based on an integral equation formulation for simulating drops in viscous fluids in the plane. It builds upon the method introduced by Kropinski in 2001, but improves on it by adding an interpolatory quadrature approach for handling near-singular integrals. Such integrals typically arise when drop boundaries come close to one another, and are difficult to compute accurately using standard quadrature rules. Adapting the interpolatory quadrature method introduced by Helsing and Ojala in 2008 to the current application, very general drop configurations can be handled while still maintaining stability and high accuracy. The performance of the new method is demonstrated by some challenging numerical examples.

description: The ambiguity function of a spatial signal in the "signal spatial frequency displacement vs antenna linear displacement" coordinates is considered in this paper; in case of a monochromatic signal with known carrier frequency, spatial signal vector angular displacement is considered as the second coordinate. The analysis is made taking into account an external (reradiated or thermal) background which contributes considerable peculiarities in the properties of the spatial ambiguity function. Accuracy of measuring the signal linear or angular displacement and resolution are determined. Examples for the Fresnel and Fraunhofer zones are given.

description: We experimentally demonstrate, with an all-optical setup, a nonlocal deterministic quantum non-demolition interaction gate applicable to quantum states at nodes separated by a physical distance and connected by classical communication channels. The gate implementation, based on entangled states shared in advance, local operations, and classical communication, runs completely in parallel fashion at both the local nodes, requiring minimum resource. The nondemolition character of the gate up to the local unitary squeezing is verified by the analysis using several coherent states. A genuine quantum nature of the gate is confirmed by the capability of deterministically producing an entangled state at the output from two separable input states. The all-optical nonlocal gate operation can be potentially incorporated into distributed quantum computing with atomic or solid state systems as a cross-processor unitary operation.

description: A model-based reconstruction technique for accelerated T2 mapping with improved accuracy is proposed using undersampled Cartesian spin-echo MRI data. The technique employs an advanced signal model for T2 relaxation that accounts for contributions from indirect echoes in a train of multiple spin echoes. An iterative solution of the nonlinear inverse reconstruction problem directly estimates spin-density and T2 maps from undersampled raw data. The algorithm is validated for simulated data as well as phantom and human brain MRI at 3 T. The performance of the advanced model is compared to conventional pixel-based fitting of echo-time images from fully sampled data. The proposed method yields more accurate T2 values than the mono-exponential model and allows for undersampling factors of at least 6. Although limitations are observed for very long T2 relaxation times, respective reconstruction problems may be overcome by a gradient dampening approach. The analytical gradient of the utilized cost function is included as Appendix.

description: Consider a linear regression model with regression parameter beta and normally distributed errors. Suppose that the parameter of interest is theta = a^T beta where a is a specified vector. Define the parameter tau = c^T beta - t where c and t are specified and a and c are linearly independent. Also suppose that we have uncertain prior information that tau = 0. Kabaila and Giri, 2009, JSPI, describe a new frequentist 1-alpha confidence interval for theta that utilizes this uncertain prior information. We compare this confidence interval with Bayesian 1-alpha equi-tailed and shortest credible intervals for theta that result from a prior density for tau that is a mixture of a rectangular "slab" and a Dirac delta function "spike", combined with noninformative prior densities for the other parameters of the model. We show that these frequentist and Bayesian interval estimators depend on the data in very different ways. We also consider some close variants of this prior distribution that lead to Bayesian and frequentist interval estimators with greater similarity. Nonetheless, as we show, substantial differences between these interval estimators remain.

description: Expert System is developed as consulting service for users spread or public requires affordable access. The Internet has become a medium for such services, but presence of mobile devices make the access becomes more widespread by utilizing mobile web and WAP (Wireless Application Protocol). Applying expert systems applications over the web and WAP requires a knowledge base representation that can be accessed simultaneously. This paper proposes single database to accommodate the knowledge representation with decision tree mapping approach. Because of the database exist, consulting application through both web and WAP can access it to provide expert system services options for more affordable for public.
Analytic Pulse Sequence Construction for Exchange-Only Quantum Computation

description: We present pulse sequences for two-qubit gates acting on encoded qubits for exchange-only quantum computation. Previous work finding such sequences has always required numerical methods due to the large search space of unitary operators acting on the space of the encoded qubits. By contrast, our construction can be understood entirely in terms of three-dimensional rotations of effective spin-1/2 pseudospins which allows us to use geometric intuition to determine the required sequence of operations analytically. The price we pay for this simplification is that, at 39 pulses, our sequences are significantly longer than the best numerically obtained sequences.

description: Thousands of people across the UK are working to deal with the direct impact of the Covid-19 pandemic. But their experiences are very different, depending on whether they are front-line key workers or community volunteers. This report presents findings from a survey of people from six local authorities in England and from a sample of community organisations and volunteers to examine social cohesion in the UK. The project, “Beyond Us and Them”, is led by the University of Kent, and Belong - The Cohesion and Integration Network, with funding from the Nuffield Foundation.

description: The analysis of charged-current quasielastic neutrino and antineutrino-nucleus scattering cross sections requires relativistic theoretical descriptions also accounting for the role of final-state interactions. We compare the results of the relativistic Green's function model with the data recently published by the MINER$ν$A Collaboration. The model is able to describe both MINER$ν$A and MiniBooNE data.

16 Years of RXTE Monitoring of Five Anomalous X-ray Pulsars

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We present a summary of the long-term evolution of various properties of the five non-transient Anomalous X-ray Pulsars (AXPs) 1E 1841-045, RXS J170849.0-400910, 1E 2259+586, 4U 0142+61, and 1E 1048.1-5937, regularly monitored with RXTE from 1996 to 2012. We focus on three properties of these sources: the evolution of the timing, pulsed flux, and pulse profile. We report several new timing anomalies and radiative events, including a putative anti-glitch seen in 1E 2259+586 in 2009, and a second epoch of very large spin-down rate fluctuations in 1E 1048.1-5937 following a large flux outburst. We compile the properties of the 11 glitches and 4 glitch candidates observed from these 5 AXPs between 1996 and 2012. Overall, these monitoring observations reveal several apparent patterns in the behavior of this sample of AXPs: large radiative changes in AXPs (including long-lived flux enhancements, short bursts, and pulse profile changes) are rare, occurring typically only every few years per source; large radiative changes are almost always accompanied by some form of timing anomaly, usually a spin-up glitch; only 20-30% of timing anomalies are accompanied by any form of radiative change. We find that AXP radiative behavior at the times of radiatively loud glitches is sufficiently similar to suggest common physical origins. The similarity in glitch properties when comparing radiatively loud and radiatively silent glitches in AXPs suggests a common physical origin in the stellar interior. Finally, the overall similarity of AXP and radio pulsar glitches suggests a common physical origin for both phenomena.

Magnetic reconnection in a comparison of topology and helicities in two and three dimensional resistive MHD simulations

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Through a direct comparison between numerical simulations in two and three dimensions, we investigate topological effects in reconnection. A simple estimate on increase in reconnection rate in three dimensions by a factor of $\sqrt{2}$, when compared with a two-dimensional case, is confirmed in our simulations. We also show that both the reconnection rate and the fraction of magnetic energy in the simulations depend linearly on the height of the reconnection region. The degree of structural complexity of a magnetic field and the underlying flow is measured by current helicity and cross-helicity. We compare results in simulations with different computational box heights.

The Pilot's house and the collaboration of the local pilots in the scientific-naval expeditions in the Patagonian coast

description: Presentation at the 26th International Congress for the History of Science and Technology, Prague, 25-31 July 2021 This paper examines a particular node of encounter and circulation of information during the first half of the 19th century: the "pilot’s house" at the mouth of the Río Negro, in Patagonia. From that place, the pilots watched over the navigation in the area and facilitated the entrance to the port of Carmen de Patagones, the southernmost town of the South American Atlantic coast at that time. Expert captains of the Patagonian navigation offered their services as pilots to merchant ships and naval expeditions. They also got engage in corsair activities, coastal trade and seal hunting. They provided reports and assisted in hydrographic surveys and they took the opportunity to copy maps and talk about the things of nature. In 1832, Captain Robert Fitz-Roy hired the services of two of these English pilots and their boats to carry out the hydrographic survey of the Patagonian coast along with officers of the HSM Beagle. The following year, Darwin stayed at the pilots' house and talked to them about these works. This paper argues that the sites such as the Pilot’s house in Patagonia operated as places of sociability and information exchange among seafarers, travellers and residents.
A class of semiprimitive groups that are graph-restrictive

description: We prove that an infinite family of semiprimitive groups are graph-restrictive. This adds to the evidence for the validity of the PSV Conjecture and increases the minimal imprimitive degree for which this conjecture is open to 12. Our result can be seen as a generalisation of the well-known theorem of Tutte on cubic graphs. The proof uses the amalgam method, adapted to this new situation.

description: This report presents first findings from our research project, “Beyond Us and Them” by the University of Kent with Belong – the Cohesion and Integration Network. The research is funded by the Nuffield Foundation. We are exploring how social cohesion within and between different groups and parts of the UK is being affected by the Covid-19 crisis. Many communities are responding positively to the crisis, as neighbours organise for mutual support to help vulnerable people. But some groups and individuals are suffering more than others. We want to understand what aspects of people’s experiences might be increasing or reducing the potential for positive relationships between different groups in society. Our questions should help policy makers to understand how their decisions can support individuals and local communities as the effects of the pandemic continue to develop or change. This first report presents some preliminary findings from our second wave survey conducted in June. We describe the demographic characteristics of the respondents, show where the research fits in the timeline of significant national events, and the report details some key findings from our questions about trust and perception of changing relationships during lockdown.
