Asymptotic reduced density matrix of discrete-time quantum walks

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

description: In this article we show that for any quantum walker with \textit{m}-dimensional coin subspace, we have $m^2\times m^2$ specific constant matrix $\mathcal{C}$ where it completely determines the asymptotic reduced density matrix of the walker. We show that for any initial state with $P_0$ projector, reduced density matrix, can be obtained by $Tr_1\left(P_0\otimes I\;\mathcal{C}\right)$ or equivalently $Tr_2\left(I\otimes P_0\;\mathcal{C}\right)$. It is worth to mention that characteristic matrix $\mathcal{C}$ is independent of the initial state and just depends on coin operator, so by finding this matrix for specific type of QW the long-time behavior of it, such as local state of the coin after a long time walking and asymptotic entanglement between coin and position will be completely known for any initial state. We have found the characteristic matrix $\mathcal{C}$ for general coin operator, $U\left(2\right)$, as well as exact form of this matrix for local initial state.

description: We investigate the phase structure of pure SU(2) LGT at finite temperature in the mixed fundamental and adjoint representation modified with a Z2 monopole chemical potential. The decoupling of the finite temperature phase transition from unphysical zero temperature bulk phase transitions is analyzed with special emphasis on the continuum limit. The possible relation of the adjoint Polyakov loop to an order parameter for the finite temperature phase transition and to the topological structure of the theory is discussed.

description: Mergers of binaries comprised of compact objects can give rise to explosive transient events, heralding the birth of exotic objects which cannot be formed through single star evolution. Using a large number of direct N-body simulations, we explore the possibility that a white dwarf (WD) is dynamically driven to tidal disruption by a stellar-mass black hole (BH) as a consequence of the joint effects of gravitational wave (GW) emission and Lidov-Kozai oscillations imposed by the tidal field of a outer tertiary companion orbiting the inner BH-WD binary. We explore the sensitivity of our results to the distributions of natal kick velocities imparted to the BH and WD upon formation, adiabatic mass loss, semi-major axes and eccentricities of the triples, and stellar mass ratios. We find rates of WD-TDEs in the range $1.2\times 10^{-3}-1.4$ Gpc$^{-3}$ yr$^{-1}$ for $z\leq 0.1$, rarer than stellar TDEs in triples by a factor of $\sim 3$--$30$. The uncertainty in the TDE rates may be greatly reduced in the future using gravitational wave (GW) observations of Galactic binaries and triples with LISA. WD-TDEs may give rise to high energy X-ray or gamma-ray transients of duration similar to long gamma-ray bursts but lacking the signatures of a core-collapse supernova, while being accompanied by a supernova-like optical transient which lasts for only days. WD--BH and WD--NS binaries will also emit GWs in the LISA band before the TDE. The discovery and identification of triple-induced WD-TDE events by future time domain surveys and/or GWs could enable the study of the demographics of BHs in nearby galaxies.

Polarimetric variations of binary stars. IV. Pre-main-sequence spectroscopic binaries located in Taurus, Auriga, and Orion
Creators: name: Manset, N.

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)

description: We present polarimetric observations of 14 pre-main-sequence (PMS) binaries located in the Taurus, Auriga, and Orion star forming regions. The majority of the average observed polarizations are below 0.5%, and none are above 0.9%. After removal of estimates of the interstellar polarization, about half the binaries have an intrinsic polarization above 0.5%, even though most of them do not present other evidences for the presence of circumstellar dust. Various tests reveal that 77% of the PMS binaries have or possibly have a variable polarization. LkCa3, Par1540, and Par2494 present detectable periodic and phase-locked variations. The periodic polarimetric variations are noisier and of a lesser amplitude (~0.1%) than for other types of binaries, such as hot stars. This could be due to stochastic events that produce deviations in the average polarization, a non-favorable geometry (circumbinary envelope), or the nature of the scatterers (dust grains are less efficient polarizers than electrons). Par1540 is a Weak-line TTauri Star, but nonetheless has enough dust in its environment to produce detectable levels of polarization and variations. A fourth interesting case is W134, which displays rapid changes in polarization that could be due to eclipses. We compare the observations with some of our numerical simulations, and also show that an analysis of the periodic polarimetric variations with the Brown, McLean, & Emslie (BME) formalism to find the orbital inclination is for the moment premature: non-periodic events introduce stochastic noise that partially masks the periodic low-amplitude variations and prevents the BME formalism from finding a reasonable estimate of the orbital inclination.

description: The aim of my thesis was to develop and characterise PrP transgenic Drosophila melanogaster of various genotypes to study the process of prion-induced neurodegeneration in this model. Prion diseases are caused by the occurrence of an abnormally-folded form of PrP (PrPSc) protein that arises either from the environment as an acquired disease, from mutation in the PrP-coding gene as a genetic disease or sporadically from causes unknown. The PrPSc then recruits PrPC, the normal form of PrP, that is ubiquitously present in the mammalian CNS and triggers neurotoxicity and neurodegeneration that is transmissible between individuals of the same or even different species. All prion diseases are currently incurable, fatal and the mechanism of prion-induced neurodegeneration remains to be discovered. In this thesis, Drosophila transgenic for ovine (chromosome 3 and dual PrP transgenic flies), hamster, humanised murine, human and cervid PrP were characterised for expression and biochemical properties. The ultimate goal of my thesis was investigation of cell-to-cell spread of misfolded PrP in Drosophila CNS. To achieve this, a mutant form of PrP that is thought to misfold was co-expressed with the normal form PrPC that served as a substrate in the same dual PrP-transgenic fly. The process was modelled using hamster, humanised murine or ovine PrP transgenes that carry human mutations associated with the spontaneous onset of transmissible neurodegeneration in the natural host. Various approaches towards independent spatial expression of PrP in Drosophila were exploited here in both single and dual PrP expressing flies. Moreover, the ability to initiate misfolding and the impact of this on the fly phenotype was investigated. Both apparent misfolding and phenotypic changes were seen in different fly models suggesting the models were successful. To this extent, PrP transgenic Drosophila were developed to allow for relatively rapid modelling of mammalian prion disease in this invertebrate organism.

description: Excerpts from the report Summary: Freezing points were determined for the principal fruits, vegetables, and florist stocks. The data can provide a guide that growers, shippers, storage operators, and others concerned with the marketing of these commodities can use to minimize or avoid freezing damage and losses. The freezing points of some living products may approach 32° F., the freezing point of water, but they never reach this point. In the tests reported, the freezing points of most fruits ranged from 27° to 30° and of most vegetables from 29° to 31°. Freezing points of florist stocks varied widely, depending to a great extent on the part of the plant tested. This report is concerned only with the temperatures at which various products may freeze. It should be emphasized that many commodities may be injured by temperatures considerably above their freezing points, a few even when stored at a temperature as high as 55° F.

Atomic Polarization and the Hanle Effect

Publisher: name: arXiv

description: This article presents an introduction to optical pumping, atomic polarization and the Hanle effect in weakly magnetized stellar atmospheres. Although the physical processes and the theoretical framework described here are of interest for applications in a variety of astrophysical contexts (e.g. scattering polarization in circumstellar envelopes and polarization in astronomical masers), the article focuses mainly on the quest for understanding the physical origin of the linearly polarized solar limb spectrum. It considers also the development of the Hanle effect as a reliable diagnostic tool for making feasible new advances in solar photospheric and chromospheric magnetism. Particular emphasis is given to a rigorous modeling of polarization phenomena as the essential link between theory and observations. Some of the most recent advances in this field are presented after carefully explaining how the various radiation pumping mechanisms lead to atomic polarization in the absence and in the presence of weak magnetic fields.

description: A negative contribution of the CH4 impurity to the thermal expansion of the solution has been revealed in dilatometric studies of solid Kr+0.76% CH4, Kr+5.25% CH4 and Kr+10.5% CH4 solutions at 1-23 K. It is shown that the negative contribution results from changes in the occupancy of the ground state of the A-modifications of isolated CH4 molecules. Assuming that the CH4 impurity singles and clusters contribute to the thermal expansion independently, we can estimate their contributions. The contribution of the singles to the thermal expansion of the solid solution is negative. The energies of the first excitational rotational states were determined for singles and two-body and three-body clusters of CH4 molecules.

description: Phosphoinositide 3-kinases (PI3Ks) are activated in immune cells downstream of the antigen recognition receptors, the signals from which are crucial for the development, differentiation and activation of lymphocytes. Engagement of the T cell antigen receptor (TCR) initiates a signalling cascade leading to the rapid induction of PI3K activity. The class IA catalytic isoform p110δ is known to be the dominant PI3K involved in signal transduction downstream of the TCR. However, the mechanism by which the TCR recruits and activates p110δ remains unresolved. This study has used a combination of proteomic, biochemical and gene editing approaches to identify proteins that are involved in the regulation of p110δ activity during TCR signalling. This work has optimised the AviTag affinity purification system for the isolation of endogenous p110 isoforms from primary murine lymphocytes. A quantitative proteomics approach was subsequently used to identify endogenous proteins that interact with p110δ in primary activated CD4+ T cells upon TCR stimulation. This analysis has identified multiple adaptor proteins and co-stimulatory receptors that may regulate p110δ activity at the TCR signalosome. This study has also developed a CRISPR/Cas9-mediated gene editing approach to disrupt targets of interest in primary murine activated T cells via ribonucleoprotein (RNP) nucleofection. This system was used to investigate the roles of the p110δ-associated proteins in TCR-induced PI3K signalling and cytokine production in activated T cells. Collectively, this work has demonstrated the potential of proteomic analysis coupled with CRISPR/Cas9 gene editing for the identification and interrogation of signalling pathway components in primary T lymphocytes. Using this approach, this study has uncovered molecular details of p110δ recruitment and activation downstream of the TCR.

description: Twisted mass QCD (tmQCD) has been introduced as a solution to the problem of unphysical fermion zero modes in lattice QCD with quarks of the Wilson type. We here argue that O(a) improvement of the tmQCD action and simple quark bilinear operators can be more economical than in the standard framework. In particular, an improved and renormalized estimator of the pion decay constant in two-flavour QCD is available, given only the Sheikholeslami-Wohlert coefficient c_sw and an estimate of the critical mass m_c.

description: A light echo around SN 1993J was observed 8.2 years after explosion by a HST WFPC2 observation, adding to the small family of supernovae with light echoes. The light echo was formed by supernova light scattered from a dust sheet, which lies 220 parsecs away from the supernova, 50 parsecs thick along the line of sight, as inferred from radius and width of the light echo. The dust inferred from the light echo surface brightness is 1000 times denser than the intercloud dust. The graphite to silicate fraction can not be determined by our BVI photometric measurements, however, a pure graphite model can be excluded based on comparison with the data. With future observations, it will be possible to measure the expansion rate of the light echo, from which an independent distance to M81 can be obtained.

Search for a heavy pseudoscalar Higgs boson decaying into a 125 GeV Higgs boson and a Z boson in final states with two tau and two light leptons at $\sqrt{s} =$ 13 TeV

description: A search is performed for a pseudoscalar Higgs boson, A, decaying into a 125 GeV Higgs boson h and a Z boson. The h boson is specifically targeted in its decay into a pair of tau leptons, while the Z boson decays into a pair of electrons or muons. A data sample of proton-proton collisions collected by the CMS experiment at the LHC at $\sqrt{s} =$ 13 TeV is used, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. No excess above the standard model background expectations is observed in data. A model-independent upper limit is set on the product of the gluon fusion production cross section for the A boson and the branching fraction to Zh $\to$ $\ell\ellττ$. The observed upper limit at 95% confidence level ranges from 27 to 5 fb for A boson masses from 220 to 400 GeV, respectively. The results are used to constrain the extended Higgs sector parameters for two benchmark scenarios of the minimal supersymmetric standard model.

description: Agriculture is predominantly rural and dominated by smallholder farmers. However, efforts to improve smallholder agricultural production have not yielded the desired results. Some scholars and practitioners have argued that development interventions often overlook the variability in smallholder farming systems. Therefore, it is unlikely that such initiatives will directly reach the smallholder end of the landholding spectrum to facilitate desired outcomes. This study examined differences within the smallholder sector in the Kassena Nankana Traditional Area, showing how socioeconomic differentiation among smallholders defines their choice of farming system. Using a mixed methods approach, this study identified three types of farms: compound, lowland, and bush farms, characterized by a differential pattern of traditional farming methods, prevalent in compound farms compared to mechanized farming practices, predominantly in lowland and bush farms. This pattern highlights the production orientation of smallholders and specifies the farming practices they engage in and rationalize to meet household consumption needs and market demand. The study concludes that resource endowments are crucial in determining farm types owned by differentiated smallholders and the farming systems they choose in response to persuasive incentives. Extension services should harness the local farmers’ understanding of soil characteristics and the diversity of farming systems when designing specific strategies to promote productivity-enhancing technologies and practices, to achieve sustainable smallholder transformations in rural Ghana.

description: For schools in England and Wales, the 1988 Education Reform Act established the foundation for a national curriculum and a new type of public examination for all pupils at the end of their compulsory schooling. In the statutory orders for English in the national curriculum and the new GCSE qualifications in English and English literature, the study of poetry was made mandatory. My object of enquiry is the poetry selected and prescribed as material for the GCSE English literature examination between 1988 and 2018. Configuring these poems, poets and collections in an original database underpins a “scalable reading” method derived from Digital Humanities. This method uses quantitative data and close reading to track the effect of policy on the poetry set text. That effect is striking: in 1988 there was a combined GCSE corpus of 6,903 poems by 1,039 poets, in 2018 there were 119 poems by 73 poets. This study explores the shifting pattern of government prescription and professional contestation over 30 years. By tracking the relationship between poets named in the national curriculum and those featured in six series of GCSE anthologies, I show the dynamics by which the pedagogical canon was reshaped. Through close reading of the most salient poems I demonstrate how this process operated within a longer historical stewardship of the pedagogical canon rooted in the poetry of Victorian mass schooling. Quantitative analysis allowed me to model the process of real-time canon formation I observed using a theoretical framework derived from anthology studies, literary reception history and period studies. This contributes a case study to debate about how schooling shapes public taste and understanding of poetry. I argue that the possibilities of poetry as encountered by young people at school have been diminished, in part the consequence of a depletion of the state’s processes and infrastructure for principled expert curriculum review. I conclude that it is timely for a less polarised debate about the place of poetry in the English curriculum, more securely grounded in the empirical evidence of subject history.

description: We review and update some aspects of deuterium chemistry in the post-recombination Universe with particular emphasis on the formation and destruction of HD. We examine in detail the available theoretical and experimental data for the leading reactions of deuterium chemistry and we highlight the areas where improvements in the determination of rate coefficients are necessary to reduce the remaining uncertainties. We discuss the cooling properties of HD and the modifications to the standard cooling function introduced by the presence of the cosmological radiation field. Finally, we consider the effects of deuterium chemistry on the dynamical collapse of primordial clouds in a simple ``top-hat'' scenario, and we speculate on the minimum mass a cloud must have in order to be able to cool in a Hubble time.

description: We present a method for comparing the H$β$ emission-line profiles of observed supermassive black hole (SBHB) candidates and models of sub-parsec SBHBs in circumbinary disks. Using the approach based on principal component analysis we infer the values of the binary parameters for the spectroscopic SBHB candidates and evaluate the parameter degeneracies, representative of the uncertainties intrinsic to such measurements. We find that as a population, the SBHB candidates favor the average value of the semimajor axis corresponding to $\log(a/M) \approx 4.20\pm 0.42$ and comparable mass ratios, $q>0.5$. If the SBHB candidates considered are true binaries, this result would suggest that there is a physical process that allows initially unequal mass systems to evolve toward comparable mass ratios (e.g., accretion that occurs preferentially onto the smaller of the black holes) or point to some, yet unspecified, selection bias. Our method also indicates that the SBHB candidates equally favor configurations in which the mini-disks are coplanar or misaligned with the binary orbital plane. If confirmed for true SBHBs, this finding would indicate the presence of a physical mechanism that maintains misalignment of the mini-disks down to sub-parsec binary separations (e.g., precession driven by gravitational torques). The probability distributions of the SBHB parameters inferred for the observed SBHB candidates and our control group of AGNs are statistically indistinguishable, implying that this method can in principle be used to interpret the observed emission-line profiles once a sample of confirmed SBHBs is available but cannot be used as a conclusive test of binarity.

description: Ce travail examine pourquoi et dans quelle mesure les concepts de justice peuvent être abordés dans le contexte de l’enseignement de l’économie et du droit au secondaire II. La première partie s’attelle à présenter un certain nombre de concepts de justice scientifiques, mais abordables, qui peuvent être facilement et régulièrement mobilisés dans des cours d’économie et de droit afin d’éclairer les raisonnements et les enjeux disciplinaires. Nous avons ainsi défini les notions clés telles que l’égalité, l’équité et la justice sociale, et présenté différentes conceptions de justice – l’utilitarisme, le libertarisme, le devoir moral, la justice comme équité – soit des systèmes de valeurs qui sous-tendent les choix en matière de justice. La seconde partie du travail vise à étudier les conditions de la transposition didactique externe des concepts de justice. Notre analyse démontre qu’un tel enseignement est légitime du point de vue institutionnel au vu d’un certain nombre d’objectifs énoncés dans les plans d’étude et de la finalité des disciplines enseignées. Il se justifie également sur le plan académique étant donné le regain d’intérêt de la communauté universitaire pour les thèmes axés sur la justice et l’équité. Nous avons également pu constater leur importance au sein du débat social. Ainsi l’enseignement des concepts de justice permet d’atteindre à travers la voie disciplinaire les objectifs institutionnels en matière de formation citoyenne et de réflexion éthique. En effet, les questions de justice offrent de riches opportunités d’aborder des notions disciplinaires clés, de développer des savoir-faire spécifiques aux disciplines, ainsi que des compétences disciplinaires. Nous identifions malgré tout certains obstacles à un tel enseignement. En particulier, les thèmes axés sur la justice ne sont pas ou peu explicitement désignés en tant que savoirs à enseigner. Par ailleurs, les enseignants manquent de ressources matérielles, les manuels étant incomplets sur ces concepts, et de savoir méthodologique pour enseigner de manière scientifique des valeurs dans le cadre des QSV

description: Mesoderm is one of the three primary germ layers from which the cardiovascular system, muscle and bone originate and derivatives of the mesoderm lineage are affected in a number of pathologies. Therefore, understanding the mechanisms regulating formation of mesoderm is interesting for a diversity of diseases and clinical application. In vivo study of human development beyond gastrulation is technically challenging and the mechanisms controlling mesoderm specification are difficult to study since the maximum number of days allowed to grow human embryos is 14 days. Thus, in this dissertation I use human pluripotent stem cells (hPSCs) as a simplified model of human development. Studies have shown that the cell cycle machinery plays a direct role in the differentiation of endoderm and ectoderm lineages but its role in guiding mesoderm subtype formation remains elusive. In this dissertation, I provide new insights of the importance of the cell cycle regulators in mesoderm specification. I first developed tools such as the FUCCI2A reporter line to isolate cells in the different cell cycle phases and to investigate propensity of mesoderm differentiation. I have shown that the propensity of differentiation into the three mesoderm subtypes lateral plate mesoderm, cardiac mesoderm and presomitic mesoderm varies during the cell cycle phases, with differentiation being more efficient in the G1 and to a lesser extend in G2/M phase. Furthermore, I developed a protocol where cells can be efficiently synchronised in the different cell cycle phases using the G2/M inhibitor nocodazole. Using this tool, I showed that developmental signalling pathways such as BMP and WNT are active in all cell cycle phases indicating that alternative mechanisms are involved in the differentiation process. In order to further explore these mechanisms, I investigated the role of cell cycle regulators controlling the G1 and G2 checkpoint. I have shown that the cell cycle regulators CDK4/6, CDK2, Retinoblastoma phosphorylation and CDK1 are essential for mesoderm subtype formation. Furthermore, I have shown that CDK1 regulates the activity of ERK1/2 signalling, an important pathway for the differentiation process confirming the existence of complex interplays between cell cycle machinery, signalling pathways and transcription factors in mesoderm subtype formation. This knowledge will be useful to further improve protocols for generating mesoderm subtypes from hPSCs for clinical applications such as drug screening, disease modelling and cell based therapy.

description: Field-guided parametrization methods have proven effective for quad meshing of surfaces; these methods compute smooth cross fields to guide the meshing process and then integrate the fields to construct a discrete mesh. A key challenge in extending these methods to three dimensions, however, is representation of field values. Whereas cross fields can be represented by tangent vector fields that form a linear space, the 3D analog---an octahedral frame field---takes values in a nonlinear manifold. In this work, we describe the space of octahedral frames in the language of differential and algebraic geometry. With this understanding, we develop geometry-aware tools for optimization of octahedral fields, namely geodesic stepping and exact projection via semidefinite relaxation. Our algebraic approach not only provides an elegant and mathematically-sound description of the space of octahedral frames but also suggests a generalization to frames whose three axes scale independently, better capturing the singular behavior we expect to see in volumetric frame fields. These new odeco frames, so-called as they are represented by orthogonally decomposable tensors, also admit a semidefinite program--based projection operator. Our description of the spaces of octahedral and odeco frames suggests computing frame fields via manifold-based optimization algorithms; we show that these algorithms efficiently produce high-quality fields while maintaining stability and smoothness.

description: We analyze X-ray spectra of heavily obscured (N_H > 10^{24} cm^{-2}) active galaxies obtained with Chandra, concentrating on the iron K alpha fluorescence line. We measure very large equivalent widths in most cases, up to 5 keV in the most extreme example. The geometry of an obscuring torus of material near the active galactic nucleus (AGN) determines the Fe emission, which we model as a function of torus opening angle, viewing angle, and optical depth. The starburst/AGN composite galaxies in this sample require small opening angles. Starburst/AGN composite galaxies in general therefore present few direct lines of sight to their central engines. These composite galaxies are common, and their large covering fractions and heavy obscuration effectively hide their intrinsically bright X-ray continua. While few distant obscured AGNs have been identified, we propose to exploit their signature large Fe K alpha equivalent widths to find more examples in X-ray surveys.

description: We analyze the asymptotic behavior of the eigenvalues of nonlinear elliptic problems under Dirichlet boundary conditions and mixed (Dirichlet, Neumann) boundary conditions on domains becoming unbounded. We make intensive use of Picone identity to overcome nonlinearity complications. Altogether the use of Picone identity makes the proof easier with respect to the known proof in the linear case. Surprisingly the asymptotic behavior under mixed boundary conditions critically differs from the case of pure Dirichlet boundary conditions for some class of problems.
