Quasi-particle re-summation and integral gap equation in thermal field theory

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A new approach to quantum field theory at finite temperature and density in arbitrary space-time dimension D is developed. We focus mainly on relativistic theories, but the approach applies to non-relativistic ones as well. In this quasi-particle re-summation, the free energy takes the free-field form but with the one-particle energy $ω(\vec{k})$ replaced by $\vep (\vec{k})$, the latter satisfying a temperature-dependent integral equation with kernel related to a zero temperature form-factor of the trace of stress-energy tensor. For 2D integrable theories the approach reduces to the thermodynamic Bethe ansatz. For relativistic theories, a thermal c-function $C_{\rm qs} (T)$ is defined for any $D$ based on the coefficient of the black body radiation formula. Thermodynamical constraints on it's flow are presented, showing that it can violate a ``c-theorem'' even in 2D. At a fixed point $C_{\rm qs}$ is a function of thermal gap parameters which generalizes Roger's dilogarithm to higher dimensions. This points to a strategy for classifying rational theories based on ``polylogarithmic ladders'' in mathematics, and many examples are worked out. An argument suggests that the 3D Ising model has $C_{\rm qs} = 7/8$. (In 3D a free fermion has $C_{\rm qs} = 3/4$.) Other applications are discussed, including the free energy of anyons in 2D and 3D, phase transitions with a chemical potential, and the equation of state for cosmological dark energy.

description: Blockchain technology promises to revolutionize manufacturing industries. For example, several supply-chain use-cases may benefit from transparent asset tracking and automated processes using smart contracts. Several real-world deployments exist where the transparency aspect of a blockchain is both an advantage and a disadvantage at the same time. The exposure of assets and business interaction represent critical risks. However, there are typically no confidentiality guarantees to protect the smart contract logic as well as the processed data. Trusted execution environments (TEE) are an emerging technology available in both edge or mobile-grade processors (e.g., Arm TrustZone) and server-grade processors (e.g., Intel SGX). TEEs shield both code and data from malicious attackers. This practical experience report presents TZ4Fabric, an extension of Hyperledger Fabric to leverage Arm TrustZone for the secure execution of smart contracts. Our design minimizes the trusted computing base executed by avoiding the execution of a whole Hyperledger Fabric node inside the TEE, which continues to run in untrusted environment. Instead, we restrict it to the execution of only the smart contract. The TZ4Fabric prototype exploits the open-source OP-TEE framework, as it supports deployments on cheap low-end devices (e.g., Raspberry Pis). Our experimental results highlight the performance trade-off due to the additional security guarantees provided by Arm TrustZone. TZ4Fabric will be released as open-source.

description: The Observatorio del Roque de los Muchachos will host the northern site of the Cherenkov Telescope Array Observatory (CTAO), in an area about 200 m below the mountain rim, where the optical telescopes are located. The site currently hosts the MAGIC Telescopes, which have gathered a unique series of 20 years of weather data. We use advanced profile likelihood methods to determine seasonal cycles, the occurrence of weather extremes, weather downtime, and long-term trends correctly taking into account data gaps. The fractality of the weather data is investigated by means of multifractal detrended fluctuation analysis. The data are published according to the Findable, Accessible, Interoperable, and Reusable (FAIR) principles. We find that the behaviour of wind and relative humidity show significant differences compared to the mountain rim. We observe an increase in temperature of $0.55\pm0.07\mathrm{(stat.)}\pm0.07\mathrm{(syst.)}^\circ C$/decade, the diurnal temperature range of $0.13\pm0.04\mathrm{(stat.)}\pm0.02\mathrm{(syst.)}^\circ C$/decade (accompanied by an increase of seasonal oscillation amplitude of $ΔC_m=0.29\pm0.10\mathrm{(stat.)}\pm0.04\mathrm{(syst.)}^\circ C$/decade) and relative humidity of $4.0\pm0.4\mathrm{(stat.)}\pm1.1\mathrm{(syst.)}$%/decade, and a decrease in trade wind speeds of $0.85\pm0.12\mathrm{(stat.)}\pm0.07\mathrm{(syst.)}$(km/h)/decade. The occurrence of extreme weather, such as tropical storms and long rains, remains constant over time. We find a significant correlation of temperature with the North Atlantic Oscillation Index and multifractal behaviour of the data. The site shows a weather-related downtime of 18.5%-20.5%, depending on the wind gust limits employed. No hints are found of a degradation of weather downtime under the assumption of a linear evolution of environmental parameters over time.

description: Asteroid (3200) Phaethon, a B-type asteroid, has been active during its perihelion passages. This asteroid is considered to be a source of the Geminid meteor stream. It is reported that this asteroid is spinning at a rotation period of $3.60 \ hr$ and has a top shape (an oblate body with an equatorial ridge) with a mean equatorial diameter of $6.25 \ km$. Here, we report that Phaethon's rotation state may be close to or above its critical rotation period when the bulk density is $0.5 \ - \ 1.5 \ {g/cm^3}$ (a typical bulk density of a B-type asteroid). We found that in this condition, the structure of Phaethon is sensitive to failure unless the cohesive strength is ${\sim}50 \ Pa \ - \ {\sim}260 \ Pa$. This result implies that if there are some surface processes driven by, for example, thermal waves, large-scaled deformation may happen and cause mass shedding. From this interpretation, we propose the processes that produced the Geminid meteor stream in the past and dust tails recently. Phaethon initially rotated at a spin period shorter than the current period. The magnitude of structural deformation at this stage was higher than the present spin condition, and a large mass shedding event, i.e., the Geminid meteor stream, occurred. After this deformation process, the body became more oblate, and its spin slowed down. At this point, while the spin was high enough for the body to have mass shedding events, the magnitude of these events became small.

description: ABSTRACT

Introduction: Multiple myeloma (MM) is an incurable, biologically heterogeneous disease of plasma cells. It is characterized by clonal proliferation of malignant plasma cells, predominantly affecting the bone marrow microenvironment and skeletal system. MM is considered a disease of the elderly, as most cases are diagnosed at a median age of 69 years. Less than 2% of patients diagnosed with MM are younger than 40 years of age. Case report: A 32-year-old male patient with a family history of multiple myeloma, with wasting syndrome of 7 months of evolution and who presented pathological fracture of the L2 vertebra; chest Computed Tomography (CT) scan showed multiple osteolytic lesions in spinal column, and the laboratory findings showed anemia, renal insufficiency, hyperphosphatemia and hypercalcemia and the serum protein electrophoresis positive for hypergammaglobulinemia, suspecting hematological neoplasia; the histopathological study confirmed a multiple myeloma. Conclusion: In Mexico, the statistics of this type of disease have been deficient, however, this diagnosis must be considered even at young age, since timely treatment reduces morbidity and mortality of these patients, favoring their prognosis.

description: The objective of this research was to identify the existence of a forage crop residues productive chain and analyze its structure and function in the Bajio de Mexico, to identify critical factors and generate recommendations to improve the integration between actors and links. Simple random sampling was used to survey 880 corn producers, sorghum, wheat and barley, 95 brokers and 200 livestock producers, from 67 municipalities in the states of Guanajuato, Michoacán, Jalisco and Queretaro. The structure of the forage crop residues production chain consists of six links and nineteen segments. Marketing margins vary by the type and presentation of the product, the most common is the 25 kg small bale. The average amount of money paid to a local producer for a hectare of forage crop residue, is $ 240.00 pesos. On average, forage crop residue sold on 25 kg small bales, allows to a commercialization agent obtain a 131% marketing margin. The main critical factors in this chain are: lack of machinery by the producers, makes it not viable the cutting and packing of forage crop residues for them; lack of organization and coordination of the chain; and the chain inequality that shows high marketing margins in favor of commercialization agents. It is important to promote the integration of crop producers to the transformation to marketing access and then improve their forage crop residue sales revenue.

description: With the new demands of the labor markets, the impositions of international organizations relating to quality of professional and models of educational management systems, institutions of higher education in Latin America, decided to start the process of quality assurance of undergraduate and graduate programs, with the aim of entering new processes to advance the development of the sector and each of the institutions. Thus, each university defines as advance the process with its own methodology, active participation of the academic community, clear policies and committed teams work; hence each program, considering their identity and context in which it develops, progresses in each stage of the process to eventually reach the highest level, maintaining the strengths and overcoming weaknesses. In this paper are related two processes following by Administration Agricultural Business program of University Pedagogical and Technological off Colombia and Bachelor in Agribusiness Management program of University Autonomy off Baja California Sur, Mexico. Emphasis is made on accreditation system, processes following by each University, the results obtained, which will be analyzed to define improvement areas and proposals to strengthen academically both programs, and the guidelines internationalization.

description: An Ising model on the kagome lattice with super-exchange interactions is solved exactly under the presence of a nonzero external magnetic field. The model generalizes the super-exchange model introduced by Fisher in 1960 and is analyzed in light of a free-fermion model. We deduce the critical condition and present detailed analyses of its thermodynamic and magnetic properties. The system is found to exhibit a second-order transition with logarithmic singularities at criticality.

Trajectories of childhood socioeconomic status and markers of cardiovascular health in adolescence
Creators: name: Marin, Teresa J.
Publisher: name: University of British Columbia
Year: 2010

description: Objective: The current study examined trajectories of socioeconomic status (SES) throughout childhood and their relationship to markers of cardiovascular health in adolescence. The goal was to determine whether early life SES, current SES, cumulative SES, and/or social mobility best explained the relationship between SES experiences across an adolescent’s lifespan and current blood pressure, heart rate (HR), and body mass index (BMI). Design: 102 medically healthy adolescents completed cardiovascular health assessments. Adolescents enrolled in the study with a parent. Parents reported on family SES, indicating the number of bedrooms in the family home for each year of the child’s life. Main Outcome Measures: Systolic blood pressure (SBP), Diastolic blood pressure (DBP), HR, and BMI. Results: Using Jones, Nagin, and Roeder’s (2001) semiparametric group-based method, four distinct trajectories of childhood SES were identified. Trajectory groups were differentially related to adolescents’ SBP and DBP. Early life SES explained trajectory group differences in adolescents’ SBP and DBP. Cumulative SES also contributed to differences in adolescents’ DBP. Trajectories of childhood SES were unrelated to HR and BMI. Trajectory findings were confirmed in follow-up analyses. Conclusions: Of the life-course models that we tested, an early life SES model best explained adolescents’ current blood pressure. These findings point toward early life developmental processes as potential candidates for explaining the relationship between SES and risk factors related to CVD. Interventions designed to reduce SES health disparities should take place early in a child’s life.

description: We construct $bb\bar{u}\bar{d}$ states on lattice using NRQCD action for bottom and HISQ action for the light up/down quarks. The NRQCD-HISQ tetraquark operators are constructed for "bound" $[bb][\bar{u}\bar{d}]$ and "molecular" $[b\bar{u}] [b\bar{d}]$ states. Corresponding to these different operators, two different appropriately tuned light quark masses are needed to obtain the desired spectra. We explain this requirement of different $m_{u/d}$ in the light of relativised quark model involving Hartree-Fock calculation. The mass spectra of double bottom tetraquark states are obtained on MILC $N_f=2+1$ Asqtad lattices at three different lattice spacings. Variational analysis has been carried out to obtain the relative contribution of "bound" and "molecular" states to the energy eigenstates.

description: In Mexico cocoa is produced in the states of the southeast region, such as Oaxaca, Veracruz, Tabasco and Chiapas; The present investigation focused on the specific analysis of the phenomenon in one of the most bountiful regions in cocoa production; the city of Tuxtla Chico, in the Soconusco of Chiapas; in which cocoa is produced and processed seed transforming artisanal chocolate. Based on publications of the National Institute of Forestry, Agricultural and Livestock Research (INIFAP) belonging to the Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA), this municipality planting and harvesting cacao good aroma and flavor, and according specialists craft homemade chocolate without artificial flavors or chemical preservatives, known today as organic, is made as usual and for domestic consumption. This research was conducted through the methodological tool mesh logical framework, establishing consistency in the phenomenon to be analyzed through building the next object of study: The small artisan chocolate producer organization in Chiapas. Were taken into account (abstract) theoretical dimensions, production, culture and family, and from the field of scientific research studies agribusiness and economic and administrative sciences. Then the problem statement, the central research question, auxiliary questions were asked; they channeled to the design of the objectives that guided the development of research, in order to achieve the desired concrete results and in a given period. His study is small organizations, some family type, which have no impact on the economic and social development of tuxtlachiquense Soconusco region, Chiapas. The present investigation shows signs of originality, because the aspects that are traditionally served in the production of handmade chocolate, lie with technical points of view from the perspective of agricultural sciences. However, the process of transforming it denotes epistemological aspects across all economic and administrative sciences.

description: This work is analyzing the sales and operations planning process as described by the operations management body of literature with respect to the application in the automotive engineering-to-order business environment. There is still a research gap in the area of the application of sales and operations planning to the engineering-to-order business situation. In order to help closing this research gap a real-world industry case out of the automotive industry featuring an engineering-to-order situation is described as an example. Based on a reference model for a sales and operations planning process, changes to the process are proposed to adapt this framework to the specific engineering to order situation. The main adaption to the state-of-theart is the inclusion of the engineering domain into the operations part of the sales and operations planning process. In literature the operations aspect of sales and operations planning is strongly focused on the manufacturing aspect of the value chain. Concrete ideas are being presented on how a sales and operations planning process that is aimed at improving overall business performance (measured by sales, profitability and cost targets) in an engineering-to-order business could look like. This work concludes with proposals to implement these ideas in the discussed industry case and mentions topics which should be addressed by further studies in this field.

description: Buffelgrass pastures lose productivity as brittlebush and other species densities increase. Profitability of controlling high densities of brittlebush in buffelgrass pastures is not well documented. The study was conducted in central Sonora to evaluate the effectiveness of Tronador® herbicide to control brittlebush and the benefit-cost relation associated with infestation reduction. Treatments were: Tronador® at 0.5, 1.0, 1.5 and 2.0% in water, Tordon 101® 1.0% in water and the untreated check. The herbicide was applied to the foliage in 40 m2 plots during the summer of 2010 by using a back sprayer. Evaluated variables were: brush mortality and buffelgrass density, basal cover, height and forage production. A randomized complete block design was used with 6 treatments and 20 replications. All variables were individually analyzed by ANOVA. Financial runs were conducted by using a computer program for Project analysis and formulation. Tronador® herbicide controlled 20, 80, 100 and 100% of brittlebush plants at rates of 0.5, 1.0, 1.5 and 2.0%, and Tordon 101® at 1% controlled 100% of the plants. Grass plants were not damaged by the herbicides. Buffelgrass density, height, basal cover and forage production was increased 35 to 180% with herbicides application. Herbicide treated areas produced annually from 1.5 to 2.16 tons of additional dry forage per hectare. Mean annual income during the projected 14 years was $241.6, $465.9 and $597.6 pesos/ha in a ranch without and with the application of Tronador® at 1.0 and 1.5% as brush control practices, respectively. A producer with a brittlebush invasion problem which applies these herbicides for vegetation control may gain additionally from $224.3 to $356.0 pesos/ha, annually.

description: Strengths and opportunity areas of educational experiences in organic agriculture (OA) in Mexico were identified. A survey was administered to students and teachers participating in OA courses, to know their opinion, also a thematic content analysis was carried out using the analysis curriculum. The existing curricula of Bachelor and Master of Science on OA available on the Internet were reviewed. The results showed that there are eight courses (learning experiences) for Bachelor degree; two MSc and one Specialty. Their main focus is on agribusiness, agro-ecology, sustainability, and technical skills. The challenges that must be addressed are poverty, food security, climate change, erosion and loss of agrobiodiversity. It is concluded, that organic agriculture programs should be based on an eclectic model that responds to different scenarios and national and global challenges and leaderships.

description: We study the boundary state associated with the decay of an unstable D-brane with uniform electric field, 1>e>0 in the string units. Compactifying the D-brane along the direction of the electric field, we find that the decay process is dominated by production of closed strings with some winding numbers; closed strings produced are such that the winding mode carries precisely the fraction $e$ of the individual string energy. This supports the conjecture that the final state at tree level is composed of winding strings with heavy oscillations turned on. As a corollary, we argue that the closed strings disperse into spacetime at a much slower rate than the case without electric field.

description: We study quantum quenches in the transverse-field Ising model defined on different lattice geometries such as chains, two- and three-leg ladders, and two-dimensional square lattices. Starting from fully polarized initial states, we consider the dynamics of the transverse and the longitudinal magnetization for quenches to weak, strong, and critical values of the transverse field. To this end, we rely on an efficient combination of numerical linked cluster expansions (NLCEs) and a forward propagation of pure states in real time. As a main result, we demonstrate that NLCEs comprising solely rectangular clusters provide a promising approach to study the real-time dynamics of two-dimensional quantum many-body systems directly in the thermodynamic limit. By comparing to existing data from the literature, we unveil that NLCEs yield converged results on time scales which are competitive to other state-of-the-art numerical methods.

Born into an extremely high level of economic prosperity, they find a better situation in the job market than previous generations. The most important influencing factors for Digital Natives are the internet and other media, as well as multi-ethnical and multicultural experiences in society beginning at an early age. Gen Z has a positive attitude towards globalization and a strong ability of realistic assessment of chances and risks of global connections. Gen Z differs from previous generations through intense use of the internet, and a high media consumption in general with a special focus on mobile devices, first and foremost smart phones. The customer buying process of Gen Z in comparison to previous generations is characterized by intense use of the internet, especially in the information phase and evaluation of alternatives. The internet is also used parallel to traditional channels, e.g. during an interviews with a sales person or while watching advertising on TV. The customer buying process has shortened considerably and traditional sales channels are losing importance. For those Digital Natives living in urban areas, the car is less attractive than other means of transport because of the high cost of ownership, and the difficult parking situation in the cities. For Gen Z, the car is no longer a status symbol, but has instead been replaced by smart phones. The questionnaire study confirms previous findings regarding the use of media and modal mix. Peer groups like friends and family are of high importance for Gen Z, as well as user reports for products. In contrast to previous studies, the random sample shows reluctance regarding the purchase of high-priced products, i.e. also cars. In the future, sustainability will become a major decisive factor for car purchase. Moreover, the seamless integration of the digital environment of the customer is a must. Innovation like self-driving cars will transform the car to a space of experience and retreat. The automotive business model must be transformed on the basis of ICT strategies. New ways of customer engagement and brand positioning will comprise optimal channel integration, an enhancement of the OEM brand image as a service provider, and the focus on offering an entertaining unique shopping experience.

description: In the Randall-Sundrum scenario we consider exact 5-dimensional solutions with localized gravity which are associated with a well defined class of conformal bulk fields. We analyze their behaviour under radion field perturbations. We show that if the Randall-Sundrum exponential warp is the localizing metric function and the equation of state of the conformal fields is not changed by the radion perturbation then the 5-dimensional solutions are unstable. We present new stable solutions which describe on the brane the dynamics of inhomogeneous dust, generalized dark radiation and homogeneous polytopic matter.

description: 'Die Säule erfordert als Gegenspieler die Wand. Ihre geschwisterlichen Beziehungen sind eindeutig.'1 (Carl August Bembè) Das Spannungsfeld zwischen tragenden Elementen und raumbegrenzenden Flächen, die enge Verwandtschaft von Säule und Wand stehen im Fokus dieser Untersuchung. Beim Herauslösen der Stütze aus der Wand wird deren raumbildende Wirkung unmittelbar sichtbar und spürbar. Die Möglichkeiten eine Fläche zu gliedern, ein Volumen zu teilen oder einen Raum aufzuspannen, gehen weit über die tragende Funktion einer Stütze hinaus, vielmehr bestimmen sie den gedachten Raum, das immaterielle Dazwischen und die Proportion des Raumes. Die tragenden Elemente können einen Raum definieren und sind dabei selbst wahrgenommene Elemente im Raum. Vergleichbar mit den Noten in der Musik schaffen sie einen Rhythmus, der dem Raum innewohnt und ihn charakterisiert. Die zugrundeliegende Ordnung, der Takt, hält das Gefüge im Inneren zusammen und dient als visuell-gedankliches Strukturgerüst der Räume. In meiner Arbeit möchte ich verschiedene Aspekte der Raumwahrnehmung beleuchten und anhand von zwei Beispielen die konstruktiven Systeme und deren Wirkung analysieren.
From quantum circuits to adiabatic algorithms

description: This paper explores several aspects of the adiabatic quantum computation model. We first show a way that directly maps any arbitrary circuit in the standard quantum computing model to an adiabatic algorithm of the same depth. Specifically, we look for a smooth time-dependent Hamiltonian whose unique ground state slowly changes from the initial state of the circuit to its final state. Since this construction requires in general an n-local Hamiltonian, we will study whether approximation is possible using previous results on ground state entanglement and perturbation theory. Finally we will point out how the adiabatic model can be relaxed in various ways to allow for 2-local partially adiabatic algorithms as well as 2-local holonomic quantum algorithms.

description: We are interested in finding the joint distribution function of the real and imaginary parts of the local Green function for a system with chaotic internal wave scattering and a uniform energy loss (absorption). For a microwave cavity attached to a single-mode antenna the same quantity has a meaning of the complex cavity impedance. Using the random matrix approach, we relate its statistics to that of the reflection coefficient and scattering phase and provide exact distributions for systems with beta=2 and beta=4 symmetry class. In the case of beta=1 we provide an interpolation formula which incorporates all known limiting cases and fits excellently available experimental data as well as diverse numeric tests.

description: Intervals between discrete events representing human activities, as well as other types of events, often obey heavy-tailed distributions, and their impacts on collective dynamics on networks such as contagion processes have been intensively studied. The literature supports that such heavy-tailed distributions are present for inter-event times associated with both individual nodes and individual edges in networks. However, the simultaneous presence of heavy-tailed distributions of inter-event times for nodes and edges is a non-trivial phenomenon, and its origin has been elusive. In the present study, we propose a generative model and its variants to explain this phenomenon. We assume that each node independently transits between a high-activity and low-activity state according to a continuous-time two-state Markov process and that, for the main model, events on an edge occur at a high rate if and only if both end nodes of the edge are in the high-activity state. In other words, two nodes interact frequently only when both nodes prefer to interact with others. The model produces distributions of inter-event times for both individual nodes and edges that resemble heavy-tailed distributions across some scales. It also produces positive correlation in consecutive inter-event times, which is another stylized observation for empirical data of human activity. We expect that our modeling framework provides a useful benchmark for investigating dynamics on temporal networks driven by non-Poissonian event sequences.

description: The Large Binocular Telescope Interferometer (LBTI) enables nulling interferometric observations across the N band (8 to 13 um) to suppress a star's bright light and probe for faint circumstellar emission. We present and statistically analyze the results from the LBTI/HOSTS (Hunt for Observable Signatures of Terrestrial Systems) survey for exozodiacal dust. By comparing our measurements to model predictions based on the Solar zodiacal dust in the N band, we estimate a 1 sigma median sensitivity of 23 zodis for early type stars and 48 zodis for Sun-like stars, where 1 zodi is the surface density of habitable zone (HZ) dust in the Solar system. Of the 38 stars observed, 10 show significant excess. A clear correlation of our detections with the presence of cold dust in the systems was found, but none with the stellar spectral type or age. The majority of Sun-like stars have relatively low HZ dust levels (best-fit median: 3 zodis, 1 sigma upper limit: 9 zodis, 95% confidence: 27 zodis based on our N band measurements), while ~20% are significantly more dusty. The Solar system's HZ dust content is consistent with being typical. Our median HZ dust level would not be a major limitation to the direct imaging search for Earth-like exoplanets, but more precise constraints are still required, in particular to evaluate the impact of exozodiacal dust for the spectroscopic characterization of imaged exo-Earth candidates.

description: We use HII starburst galaxy apparent magnitude measurements to constrain cosmological parameters in six cosmological models. A joint analysis of HII galaxy, quasar angular size, baryon acoustic oscillations peak length scale, and Hubble parameter measurements result in relatively model-independent and restrictive estimates of the current values of the non-relativistic matter density parameter $Ω_{\rm m_0}$ and the Hubble constant $H_0$. These estimates favor a 2.0$σ$ to 3.4$σ$ (depending on cosmological model) lower $H_0$ than what is measured from the local expansion rate. The combined data are consistent with dark energy being a cosmological constant and with flat spatial hypersurfaces, but do not strongly rule out mild dark energy dynamics or slightly non-flat spatial geometries.
