description: Since the early 1990s, researchers have routinely used count data models (such as the Poisson and negative binomial) to estimate the demand for recreational activities. Along with the success and popularity of count data models in recreational demand analysis during the last decade, a number of shortcomings of standard count data models became obvious to researchers. This had led to the development of new and more sophisticated model specifications. Furthermore, semi-parametric and non-parametric approaches have also made their way into count data models. Despite these advances, however, one interesting issue has received little research attention in this area. This is related to the fast decay process of the dependent variable and the associated long tail. This phenomenon is observed quite frequently in recreational demand studies; most recreationists make one or two trips while a few of them make exceedingly large number of trips. This introduces an extreme form of overdispersion difficult to address in popular count data models. The major objective of this paper is to investigate the issues related to proper modelling of the fast decay process and the associated long tails in recreation demand analysis. For this purpose, we introduce two categories of alternative count data models. The first group includes four alternative count data models, each characterised by a single parameter while the second group includes one count data model characterised by two parameters. This paper demonstrates how these alternative models can be used to properly model the fast decay process and the associated long tail commonly observed in recreation demand analysis. The first four alternative count data models are based on an adaptation of the geometric, Borel, logarithmic and Yule probability distributions to count data models while the second group of models relied on the use of the generalised Poisson probability distribution. All these alternative count data models are empirically implemented using the maximum likelihood estimation procedure and applied to study the demand for moose hunting in Northern Ontario. Econometric results indicate that most of the alternative count data models proposed in this paper are able to capture the fast decay process characterising the number of moose hunting trips. Overall they seem to perform as well as the conventional negative binomial model and better than the Poisson specification. However further investigation of the econometric results reveal that the geometric and generalised Poisson model specifications fare better than the modified Borel and Yule regression models.

description: We prove a relative version of Kontsevich's formality theorem. This theorem involves a manifold M and a submanifold C and reduces to Kontsevich's theorem if C=M. It states that the DGLA of multivector fields on an infinitesimal neighbourhood of C is L-infinity-quasiisomorphic to the DGLA of multidifferential operators acting on sections of the exterior algebra of the conormal bundle. Applications to the deformation quantisation of coisotropic submanifolds are given. The proof uses a duality transformation to reduce the theorem to a version of Kontsevich's theorem for supermanifolds, which we also discuss. In physical language, the result states that there is a duality between the Poisson sigma model on a manifold with a D-brane and the Poisson sigma model on a supermanifold without branes (or, more properly, with a brane which extends over the whole supermanifold).

description: This dissertation proposes a multi-material co-sinterable ceramic monolith fabrication method based on additive manufacturing, capable of producing ceramic monoliths with internal flow channel structures and demonstrating the potential for high-temperature applications. The research utilizes powder printing and layer-by-layer pressing techniques to address the performance limitations imposed by sealing materials in existing high-temperature ceramic applications. The study is grounded in the low-temperature sintering of high-density YSZ ceramic powder and verifies the co-sinterability of multiple material powders. It further explores the selection of fugitive materials and strategies for optimizing springback behavior in dry pressing. Additionally, a nozzle printing technology for dry ceramic powders is developed. Finally, an experimental platform is established to validate the feasibility of the Dry Powder Printing Additive Manufacturing (DPP-AM) technique for fabricating ceramic monoliths with micro-scale flow channels. The findings of this research have the potential to advance ceramic industry applications in high-temperature heat exchangers and ionic transport devices.

description: We have theoretically predicted the density of states(DOS), the low temperature specific heat, and Brillouin scattering spectra of a large, free standing array of coupled nano-oscillators. We have found significant gaps in the DOS of 2D elastic systems, and predict the average DOS to be nearly independent of frequency over a broad band f < 50GHz. At low temperatures, the measurements probe the quantum statistics obeyed by rigid body modes of the array and, thus, could be used to verify the quantization of the associated energy levels. These states, in turn, involve center-of mass motion of large numbers of atoms, N > 1.e14, and therefore such observations would extend the domain in which quantum mechanics has been experimentally tested. We have found the required measurement capability to carry out this investigation to be within reach of current technology.

description: Seit einigen Jahren spielen Bewertungen auf Online-Plattformen im Restaurantsgeschäft eine immer wichtigere Rolle. Immer stärker sind es verfügbare Informationen im Internet, die den Kosum leiten und die Auswahl der Restaurantkunden motivieren. Das Ziel dieser Arbeit ist es, den Einfluss solcher Information zu erkennen und zu messen. Hierzu analysieren wir einen TripAdvisor Datensatz, der Restaurantdaten aus 31 europäischen Städten umfasst. Wir führen die Variablen ein, und visualisieren diese Variablen mit verschiedenen Diagrammerstellungstechniken. Hierfür teilen wir die Analysein einen Städte-fokussierten und einen Städte-unabhängigen Teil. Für den Städte-fokussierten Teil arbeiten wir heraus, wie sich Städte in wichtigen Variablen unterscheiden. Außerdem präsentieren wir eine Cluster-Analyse, die uns erlaubt, die Ähnlichkeit zwischen Städten als räumliche Nähe darzustellen. In dem Städte-unabhängigen Teil arbeiten wir Korrelationen zwischen Variablen heraus und präsentieren zwei Regressionsmodelle. Eines basierendauf einer multiplen linearen Regression und das andere auf einem Entscheidungsbaum.
description: In recent years, reviews on online plattforms are playing an increasingly important role for the restaurant business.The publicly available information helps restaurant clients to make decisions. The aim of this thesis is to recognize and measure the influence of such information. For this purpose, we analyze a TripAdvisor dataset. It covers restaurant data from 31 European cities. We define variables and visualize them using different charting tools in R. We separate the analysis into a city-focused part and a city-independent part. For the city-focused part, we work out how the cities differ in important variables. Also, we present a cluster analysis, which enables us to express the similarity between the cities as spatial proximity. In the city-independent part we study the correlations between variables and present two regression models. One based on a multiple linear regression, and the other on a decision tree.
On Silicon Carbide Grains as the Carrier of the 21 Micron Emission Feature in Post-Asymptotic Giant Branch Stars

description: The mysterious 21mu emission feature seen in 12 proto-planetary nebulae (PPNe) remains unidentified since its first detection in 1989. Over a dozen of candidate materials have been proposed within the past decade, but none of them has received general acceptance. Very recently, silicon carbide (SiC) grains with impurities were suggested to be the carrier of this enigmatic feature, based on recent laboratory data that doped SiC grains exhibit a resonance at \~21mu. This proposal gains strength from the fact that SiC is a common dust species in carbon-rich circumstellar envelopes. However, SiC dust has a strong vibrational band at ~11.3mu. We show in this Letter that in order to be consistent with the observed flux ratios of the 11.3mu feature to the 21mu feature, the band strength of the 21mu resonance has to be very strong, too strong to be consistent with current laboratory measurements. But this does not yet readily rule out the SiC hypothesis since recent experimental results have demonstrated that the 21mu resonance of doped SiC becomes stronger as the C impurity increases. Further laboratory measurements of SiC dust with high fractions of C impurity are urgently needed to test the hypothesis of SiC as the carrier of the 21mu feature.

description: We describe classical stochastic processes by using dynamical Lee-Yang zeros. The system is in contact with external leads and the time evolution is described by the two-state classical master equation. The cumulant generating function is written in a factorized form and the current distribution of the system is characterized by the dynamical Lee-Yang zeros. We show that a continuous distribution of zeros is obtained by discretizing the time variable. When the transition probability is a periodically-oscillating function of time, the distribution of zeros splits into many parts. We study the geometric property of the current by comparing the result with that of the adiabatic approximation. We also use the Floquet-Magnus expansion in the continuous-time case to study dynamical effects on the current at the fast-driving regime.

description: We have used INTEGRAL & RXTE data to investigate the timing properties of the source in correlation with its spectral states as defined by different positions in the colour-colour diagram. The source shows two distinct branches in the colour-colour diagram that resemble those of the Z sources. The hard branch (similar to the horizontal branch of Z sources) is characterised by a low-amplitude change of the hard colour compared to the change in the soft colour. In the soft branch (analogue to the normal branch) the amplitude of variability of the hard colour is about three times larger than that of the soft colour. As the count rate decreases the source moves up gradually through the soft to the hard branch. The aperiodic variability (excluding the pulse noise) consists of band-limited noise (represented by three broad Lorentzian components) and two QPOs at 0.05 Hz and 0.22 Hz. The strength of the lower frequency QPO increases as the source approaches the hard branch (similar to HBOs in Z sources). The higher frequency QPO reaches maximum significance when the source is in the middle of the branch (like NBOs). We have performed the first measurements of phase lags in the band limited noise below 8 Hz in an accreting X-ray pulsar and found that soft lags dominate at high frequencies. Above the pulse frequency (0.23 Hz), the amplitude of the lag increases as the X-ray flux increases. The Z topology appears to be a signature of the neutron star binaries as it is present in all types of neutron-star binaries (Z, atoll and, as we show here, in accreting pulsars as well). However, the motion along this track, the time scales through the different branches of the diagram and the aperiodic variability associated with portions of the Z track differ for each subclass of neutron-star binary.

description: Sharing economies enabled by technical platforms have been studied regarding their economic, legal, and social effects, as well as with regard to their possible influences on CSCW topics such as work, collaboration, and trust. While a lot current research is focusing on the sharing economy and related communities, there is little work addressing the phenomenon from a socio-technical point of view. Our workshop is meant to address this gap. Building on research themes and discussion from last year’s ECSCW, we seek to engage deeper with topics such as novel socio-technical approaches for enabling sharing communities, discussing issues around digital consumer and worker protection, as well as emerging challenges and opportunities of existing platforms and approaches.

description: This workshop discusses organizational resilience and resilient infrastructures by uniting researchers, professionals, and experts from various disciplines. Workplace studies and organizational settings have always been an integral theme in computer-supported cooperative work (CSCW) research. This workshop hopes to broaden this research horizon by overlapping the multidisciplinary perspectives of resilience and crisis research with human-computer interaction (HCI), CSCW, organizational, and business studies. The COVID-19 pandemic and the subsequent physical and social constraints have been detrimental to the activities of different organizations, especially to small and medium enterprises (SMEs). SMEs must recognize and search for opportunities to adapt to this crisis by developing resilient organizational infrastructures. These adaptations can be crucial to overcoming the current disruptions challenging the continued existence keeping in view the intrinsic diversification of various business and industrial sectors. How organizational infrastructures can be designed to instill resilient properties like adaptive capacity, self-adjustment and continuity? We intend to focus on bringing this discussion under the umbrella of CSCW to explore the potentials of collaboration and cooperative work in organizational infrastructure. Through this workshop, we offer research prospects by applying organizational resilience theories to study organizational infrastructure and infrastructuring activities, which can be used for their prospective transformations into resilient infrastructures.

description: Multiple waves of the COVID-19 pandemic, social unrest, global economic crisis, and mental health issues have caused modifications to developer work practices, which presents an emergent need to understand its impact on research ​about developers. The aim of this workshop is to bring together researchers from academia and industry to discuss the current state of research about developers, questions asked or problems addressed, strategies applied, and to share successes and failures in the form of ‘lessons learnt’. We are also interested in observations about new practices and processes adopted by developers in the field during these crises. We hope to capture a set of (i) observations in developer practices, consequently leading to shifts in research problems of interest, and (ii) suggestions for best practices and strategies that can be adopted by researchers to effectively plan and execute research about developers amidst and post global crises.

description: An experiment was carried out at the Department of Horticulture at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh for the investigation of the performance of different concentration of Indole-3-Butyric Acid (IBA) for sprouting and rooting potential of Bougainvillea spectabilis tem cutting during the period from May 2013 to August 2013. Five treatments viz. T0: Control; T1: IBA in dust form; T2: IBA 500-ppm; T3: IBA 1000-ppm and T4: IBA 2000-ppm were exploited on the experiment with five replication. In case of T2, T3 and T4 cuttings were soaked for 24 hours on the respective solutions. From the experiment it was found that IBA play an important role for successful asexual propagation of bougainvillea through cutting. Better performance was found when cut stems were soaked for 24 hours before the establishment of stem cutting. But performance was inhibited by increasing concentrations of IBA in terms of all of the features on which data had taken.
During the experimental period, data was taken on different attributes and T3 (1000-ppm) was performed as the best among the treatments which as followings: days to first rooting (4.0), days to first sprout bud initiation (5.3), number of sprout bud/cutting (3.6), number of leaves/cutting (35.2), length of sprout (15.0 cm), number of branches/cutting (4.7), number of root/cutting (64.2), number of sub root/cutting (25.8), longest root length (33.2 cm), longest root diameter (0.51 mm), rooting % (100%), survival % of rooted cuttings (100%). Though 100% rooting was also found in 500-ppm and 2000-pmm but only 1000-ppm was resulted 100% survival of rooted cuttings.

description: Platformization is transforming the way work is organized in a variety of businesses. The CSCW literature contains substantial amount of research on platforms, but this research to date has mainly been focusing on two-sided global platforms such as social media, on-demand labor, and crowdsourcing platforms. In many European countries, platformization of traditional organizations, both private and public, is well underway and accelerated by the pandemic. Platformization as a process can affect how we design systems –i.e. the platform itself and its peripheral applications and customizations –and how we use platforms for collaboration. Through this workshop we want to engage academics and practitioners in a discussion of the platformization of collaborative work in organizations. Topics include but are not limited to platform design and development, platformization processes, and platforms and work practice evolution. The socio-technical nature of platforms indicates that working across disciplines has become crucial for platform research. We therefore invite participants from all relevant disciplines.

We analyze the possibility of a phase transition from hadronic matter to gCFL quark matter and we discuss, for different values of the strange quark mass and diquark coupling strength, the existence of a gCFL phase in quark or hybrid stars. The mass-radius relation and the structure of compact stars containing the gCFL phase are shown and the physical relevance of this superconducting phase inside a stellar object is also discussed.

description: The increased popularity of UX design practices in the industry led to the creation of more usable, useful, and enjoyable digital products and services. Nonetheless, the scope of the UX efforts generally concerns a single product or project under development. In this workshop, we call for the shift beyond a single product paradigm towards a more ecosystemic approach in UX design to create long-lasting, reusable, and transferable UX artifacts. Gathering a group of scholars who are interested in UX processes at work, and UX practitioners, leaders, and managers, we aim to synthesize the current state of the discussion to create a UX research agenda for designing integrated digital work environments, unpacking development, users, and change perspectives to aid knowledge transfer across projects and overtime.

description: Within the fields of Human-Computer Interaction (HCI) and Computer- Supported Cooperative Work (CSCW), there is a wide acknowledgement that, in order to design useful and usable interactive systems, it is key to accurately understand users, their contexts and the practices they engage with. For that, HCI and CSCW professionals have for long been drawing on socio-scientific methods as a means towards it. While much has been said in terms of methods that can be used to capture the user contexts and associated practices, considerably less is found on how the collected data can be systematically analysed, in order to generate trustworthy representations of what has been heard and observed from participants. One possible reason for that is the lack of training of researchers in the area to use appropriate data analysis techniques. This masterclass sets out to address this gap. It aims at providing HCI and CSCW researchers and practitioners with deep knowledge about one of the most popular data analysis technique of the moment: Thematic Analysis (TA). Through a practical exercise, the masterclass will introduce and explore the procedures involved in carrying out TA, so to equip professionals from the field with the necessary tools to have a good understanding of the relevant user contexts and practices for the design of innovative, useful and usable interactive systems.
Scattering theory and equation of state of a spherical two-dimensional Bose gas

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We analyze the scattering problem of identical bosonic particles confined on a spherical surface. At low scattering energies and for a radius much larger than the healing length, we express the contact interaction strength in terms of the s-wave scattering length. Adopting this relation, we are then able to regularize the zero-point energy of the spherical Bose gas and to obtain its equation of state, which includes the corrections due to the finite radius of the sphere and coincides with the flat-case result in the infinite-radius limit. We also provide a microscopic derivation of the superfluid density of the system, reproducing a result postulated in a previous work. Our results are relevant for modeling the ongoing microgravity experiments with two-dimensional bubble-trapped Bose-Einstein condensates.

description: We extract pairing gap in $^{184}$W at finite temperature for the first time from the experimental level densities of $^{183}$W, $^{184}$W, and $^{185}$W using "thermal" odd-even mass difference. We found the quenching of pairing gap near the critical temperature $T_c = 0.47$ MeV in the BCS calculations. It is shown that the monopole pairing model with a deformed Woods-Saxon potential explains the reduction of the pairing correlation using the partition function with the number parity projection in the static path approximation plus random-phase approximation.

Year: 2021

description: Understanding user contexts and practices for the design and development of useful and usable technologies has for long been acknowledged as relevant within the fields of Human-Computer Interaction (HCI) and Computer-Supported Cooperative Work (CSCW). Taking account of the growing interest in human practices for the design and quality assessment of digital technologies, Grounded Design (GD) has been introduced as a paradigm for design research and practice. As a research paradigm, GD focuses on investigating changes in human practices stemming from the use and appropriation of digital technologies. The results of such investigations are used as input for the design and development of new and innovative digital solutions. In this context, Design Case Study (DCS) serves as a framework to orient and document research and practice predicated on GD. The framework, which is organised in three interdependent phases – pre-study, design and appropriation –, provides useful guidance and infrastructure for successful GD initiatives. This masterclass sets out to demonstrate how DCS can be used to accomplish relevant and impacting GD projects. It will introduce the conceptual and theoretical grounds behind the framework, as well as discuss the different methods and methodologies which can be used for it.

description: We report about the application of state-of-the-art deep learning techniques to the automatic and interpretable assignment of ICD-O3 topography and morphology codes to free-text cancer reports. We present results on a large dataset (more than 80 000 labeled and 1 500 000 unlabeled anonymized reports written in Italian and collected from hospitals in Tuscany over more than a decade) and with a large number of classes (134 morphological classes and 61 topographical classes). We compare alternative architectures in terms of prediction accuracy and interpretability and show that our best model achieves a multiclass accuracy of 90.3% on topography site assignment and 84.8% on morphology type assignment. We found that in this context hierarchical models are not better than flat models and that an element-wise maximum aggregator is slightly better than attentive models on site classification. Moreover, the maximum aggregator offers a way to interpret the classification process.

Geotechnical studies of retreat pillar coal mining at shallow depth
Creators: name: Cullen, Michael
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents the results of research into geotechnical aspects of retreat pillar coal mining at shallow depth (less than 100m). The fieldwork component was carried out over a four-year period at the Quinsam Coal Mine. The geotechnical aspects investigated were excavation stability, excavation support, pillar design, gob cave prediction, and subsidence. These were all considered critical aspects of safe and cost effective mining. Geotechnical design at the Quinsam Coal Mine was initially carried out using existing design tools. For the most part these tools were developed at moderate to deep depth mines (greater than 100m). The suitability of these tools at shallow depth mines was previously not known; as such the primary objectives of this research were: 1) to determine if the existing geotechnical design tools were applicable at shallow depth, 2) to develop new design methods where the existing tools were found to not be suitable, 3) to improve safety, productivity and costs at shallow depth retreat pillar coal mines. Suitable existing tools where found for design of ground support, pillar size, excavation size, and gob cave prediction. Existing tools where not found to be suitable for prediction of caving and surface subsidence. The cave height at shallow depth was determined to extend much higher than predicted by existing methods. The extent of the ground surface affected by subsidence was determined to be much less than that predicted by existing methods. New tools for predicting caving and subsidence have been developed based on measurements at the Quinsam Coal Mine supplemented with numerical modelling. The distinct response of the rock mass to mining at shallow depth is attributed to the magnitude and orientation of the induced stresses. At shallow depth low compressive and tensile stresses are more likely to occur, and more likely to extend for a greater distance into the rock mass above the excavation. Although this work is based on studies carried out at the Quinsam Coal Mine it is believed that the findings can be applied to other shallow depth coal mines in similar geological environments. Since adopting many of the recommendations and design procedures developed through this work, the Quinsam Coal Mine has achieved significant improvements in safety, productivity, and costs.

description: This study on turmeric was conducted at Sher-e-Bangla Agricultural University, Dhaka during the period from April 2010 to March 2011. Five different fertilizer combinations were used in this experiment. Number of tiller per clump, weight of mother rhizome per plant, weight of primary and secondary finger per plant were significantly highest from F2 and lowest from F0. Highest turmeric yield per hectare (11.6 t/ha) was obtained from F2 and the lowest (5.7 t/ha) was observed from F0.
Hydrogen inserted into the Si(100)-2x1-H surface: A first-principles study

description: An H atom inserted into hydrogen monolayer on the Si(100)-2x1 surface has been studied using the density functional theory. Hydrogen-induced defects were considered in their neutral, negative, and positive charge states. It was found that hydrogen atom forms a dihydride unit on the surface in the most stable neutral and negative charge states. Hydrogen located in the groove between dimer rows and bonded with a second-layer Si atom is also one of the most stable negative charge states. In the positive charge state, hydrogen forms a three-center bond inside a Si dimer, Si-H-Si, similar to the bulk case. A comparison of simulated scanning tunneling microscopy (STM) images with experimental data available in the literature showed that neutral and negatively charged hydrogen-induced defects were already observed in experiments. The results reveal that the adsorption position of an H atom inserted into the Si(100)-2x1-H surface is determined by the charge state of the hydrogen-induced defect.

description: We present a new ab initio method for calculating effective onsite Coulomb interactions of itinerant and strongly correlated electron systems. The method is based on constrained local density functional theory formulated in terms of maximally localized Wannier functions. This scheme can be implemented with any basis, and thus allows us to perform the constrained calculation with plane-wave-based electronic-structure codes. We apply the developed method to the evaluation of the onsite interaction of 3d transition-matal series. The results are discussed using a heuristic formula for screened Coulomb interactions.

description: Semantic interaction (SI) attempts to learn the user's cognitive intents as they directly manipulate data projections during sensemaking activity. For text analysis, prior implementations of SI have used common data features, such as bag-of-words representations, for machine learning from user interactions. Instead, we hypothesize that features derived from deep learning word embeddings will enable SI to better capture the user's subtle intents. However, evaluating these effects is difficult. SI systems are usually evaluated by a human-centred qualitative approach, by observing the utility and effectiveness of the application for end-users. This approach has drawbacks in terms of replicability, scalability, and objectiveness, which makes it hard to perform convincing contrast experiments between different SI models. To tackle this problem, we explore a quantitative algorithm-centered analysis as a complementary evaluation approach, by simulating users' interactions and calculating the accuracy of the learned model. We use these methods to compare word-embeddings to bag-of-words features for SI.

title: An Application and Evaluation of a Methodology for Testing Operational Level Training Simulations
Creators: name: Neal, Karl Dean
Publisher: name: Old Dominion University Libraries
Year: 2005

description: The Virginia Modeling, Analysis and Simulation Center has developed a methodology for testing operational-level training simulation systems. The methodology is built on analyses of the military tasks that an operational-level simulation is intended to train. These tasks are derived from the U.S. Department of Defense Universal Joint Task List. The methodology analyzes the categories of capabilities the simulation should have to support those tasks based on operational-level-military entities and actions. Cross-referencing the tasks and capabilities leads to functionality items the simulation should have. The methodology focuses on training joint force command tasks and decision making at the operational level of combat.

The methodology was tested by applying it to an existing operational level training simulation system during an actual training exercise, and subsequently, in a non-exercise controlled test environment. Based on those tests, the methodology's ability to measure the effectiveness of an operational level training simulation is evaluated. The process of applying the methodology from pre-exercise through post-exercise activities is documented as a basis for future applications of this methodology. Issues with the methodology and any improvements necessary are identified.

description: We investigate the interplay between amplitude and square-gradient scattering from the rough surfaces in multi-mode waveguides (conducting quantum wires). The main result is that for any (even small in height) roughness the square-gradient terms in the expression for the wave scattering length (electron mean free path) are dominant, provided the correlation length of the surface disorder is small enough. This important effect is missed in existing studies of the surface scattering.

description: The nearest exoplanets to the Sun are our best possibilities for detailed characterization. We report the discovery of a compact multi-planet system of super-Earths orbiting the nearby red dwarf GJ 887, using radial velocity measurements. The planets have orbital periods of 9.3 and 21.8~days. Assuming an Earth-like albedo, the equilibrium temperature of the 21.8 day planet is approx 350 K; which is interior, but close to the inner edge, of the liquid-water habitable zone. We also detect a further unconfirmed signal with a period of 50 days which could correspond to a third super-Earth in a more temperate orbit. GJ 887 is an unusually magnetically quiet red dwarf with a photometric variability below 500 parts-per-million, making its planets amenable to phase-resolved photometric characterization.

Dynamical Floquet spectrum of Kekulé-distorted graphene under normal incidence of electromagnetic radiation

description: Electromagnetic dressing by a high-frequency field drastically modifies the electronic transport properties on Dirac systems. Here its effects on the energy spectrum of graphene with two possible phases of Kekulé distortion (namely, Kek-Y and Kek-O textures) are studied. Using Floquet theory it is shown how circularly polarized light modifies the gapless spectrum of the Kek-Y texture, producing dynamical band gaps at the Dirac point that depends on the amplitude and the frequency of the electric field, and breaks the valley degeneracy of the gapped spectrum of the Kek-O texture. To further explore the electronic properties under circularly polarized radiation, the dc conductivity is studied by using the Boltzmann approach and considering both inter-valley and intra-valley contributions. When linearly polarized light is considered, the band structure of both textures is always modified in a perpendicular direction to the electric field. While the band structure for the Kek-Y texture remains gapless, the gap for the Kek-O texture is reduced considerably. For this linear polarization it is also shown that non-dispersive bands can appear by a precise tuning of the light field parameters thus inducing dynamical localization. The present results suggest that optical measurements will allow to distinguish between different Kekulé bond textures.
