description: Charge order has recently been identified as a leading competitor of high-temperature superconductivity in moderately doped cuprates. We provide a survey of universal and materials-specific aspects of this phenomenon, with emphasis on results obtained by scattering methods. In particular, we discuss the structure, periodicity, and stability range of the charge-ordered state, its response to various external perturbations, the influence of disorder, the coexistence and competition with superconductivity, as well as collective charge dynamics. In the context of this journal issue which honors Roger Cowley's legacy, we also discuss the connection of charge ordering with lattice vibrations and the central-peak phenomenon. We end the review with an outlook on research opportunities offered by new synthesis methods and experimental platforms, including cuprate thin films and superlattices.

description: Η παρούσα μελέτη βασίζεται σε πρωτογενή δεδομένα τα οποία συλλέχθηκαν με τη μέθοδο του δομημένου ερωτηματολογίου. Η έρευνα διεξήχθη στη Πιερία και αφορά επιχειρήσεις του μεταποιητικού τομέα της οικονομίας, οι οποίες είτε έχουν αναπτύξει εξαγωγική δραστηριότητα, είτε αποτελούν εν δυνάμει εξαγωγικές επιχειρήσεις. Σκοπός της παρούσας έρευνας είναι μέσω της πρωτογενούς έρευνας να συλλεχθούν όλες οι απαραίτητες πληροφορίες σχετικά με την εξαγωγική δραστηριότητα των επιχειρήσεων, ώστε να εξαχθούν συμπεράσματα. Μέσω της ανάλυσης των δεδομένων τις έρευνας αναδεικνύονται τα σημαντικότερα εξαγωγικά προβλήματα που αντιμετωπίζουν οι επιχειρήσεις καθώς και τα εμπόδια που αποτρέπουν την ανάπτυξη εξαγωγικής δραστηριότητας. Επίσης, μέσω τις στατιστικής ανάλυσης γίνεται μια προσπάθεια προσδιορισμού των πιθανών παραγόντων-χαρακτηριστικών της επιχείρησης που ασκούν θετική ή αρνητική επίδραση στην εξαγωγική επίδοση των επιχειρήσεων. Πέρα όμως του διττού αυτού σκοπού της παρούσας έρευνας αναδεικνύονται και επιπλέον χρήσιμες πληροφορίες από την εξέταση της εξαγωγικής δραστηριότητας των επιχειρήσεων της Πιερίας, με τα ανταγωνιστικά πλεονεκτήματα που έχουν αναπτύξει οι εξαγωγικές επιχειρήσεις στη διεθνή αγορά, να αποτελούν μια από αυτές. Τέλος, προτείνονται ορισμένες προτάσεις πολιτικής για την ενίσχυση της εξωστρέφειας, με στόχο την άμβλυνση των αρνητικών συνεπειών της κρίσης τόσο σε επίπεδο επιχείρησης όσο και σε επίπεδο οικονομίας, ως σύνολο.
description: This study is based on data collected with the method of structure questionnaire. The survey was conducted in Pieria and concern 53 firms which they belong to the manufacturing sector of the economy. These firms have already developed export activity or they are potential exporters. The purpose of this study is twofold. Firstly, this primary research aims at the investigation and the apprehension in depth of the export problems faced by these firms and the export barriers that prevent some of them from the development of an export activity. Moreover, through the statistical analysis this study identifies the determinant of export performance. Apart from that, useful and notable information has emerged through the investigation of the export activity of the firms, included in sample, such as the competitive advantage developed to compete successfully overseas. Finally, policy suggestions are proposed in order to enhance export performance and create an export culture. The final aim is the mitigation of the negative effect of financial crisis both at micro and macro level.

description: Producing manual, pixel-accurate, image segmentation labels is tedious and time-consuming. This is often a rate-limiting factor when large amounts of labeled images are required, such as for training deep convolutional networks for instrument-background segmentation in surgical scenes. No large datasets comparable to industry standards in the computer vision community are available for this task. To circumvent this problem, we propose to automate the creation of a realistic training dataset by exploiting techniques stemming from special effects and harnessing them to target training performance rather than visual appeal. Foreground data is captured by placing sample surgical instruments over a chroma key (a.k.a. green screen) in a controlled environment, thereby making extraction of the relevant image segment straightforward. Multiple lighting conditions and viewpoints can be captured and introduced in the simulation by moving the instruments and camera and modulating the light source. Background data is captured by collecting videos that do not contain instruments. In the absence of pre-existing instrument-free background videos, minimal labeling effort is required, just to select frames that do not contain surgical instruments from videos of surgical interventions freely available online. We compare different methods to blend instruments over tissue and propose a novel data augmentation approach that takes advantage of the plurality of options. We show that by training a vanilla U-Net on semi-synthetic data only and applying a simple post-processing, we are able to match the results of the same network trained on a publicly available manually labeled real dataset.

Sharp Strichartz estimates for some variable coefficient Schrödinger operators on $\mathbb{R}\times\mathbb{T}^2$

Subjects: subject: Analysis of PDEs (math.AP)

description: In the first part of the paper we continue the study of solutions to Schrödinger equations with a time singularity in the dispersive relation and in the periodic setting. In the second we show that if the Schrödinger operator involves a Laplace operator with variable coefficients with a particular dependence on the space variables, then one can prove Strichartz estimates at the same regularity as that needed for constant coefficients. Our work presents a two dimensional analysis, but we expect that with the obvious adjustments similar results are available in higher dimensions.

description: Conventional wisdom holds that no four-dimensional gravity field theory can be ultraviolet finite. This understanding is based mainly on power counting. Recent studies confirm that one-loop N = 8 supergravity amplitudes satisfy the so-called `no-triangle hypothesis', which states that triangle and bubble integrals cancel from these amplitudes. A consequence of this hypothesis is that for any number of external legs, at one loop N = 8 supergravity and N = 4 super-Yang-Mills have identical superficial degrees of ultraviolet behavior in D dimensions. We describe how the unitarity method allows us to promote these one-loop cancellations to higher loops, suggesting that previous power counts were too conservative. We discuss higher-loop evidence suggesting that N = 8 supergravity has the same degree of divergence as N = 4 super-Yang-Mills theory and is ultraviolet finite in four dimensions. We comment on calculations needed to reinforce this proposal, which are feasible using the unitarity method.

Το εν λόγω κείμενο αποτελεί ιδανικό παράδειγμα προς ανάλυση για τη μελέτη των διαλέκτων, των ιδιωματισμών και των πολιτισμικών αναφορών όσον αφορά τη μετάφραση και απόδοσή τους στην ελληνική γλώσσα. Συνολικά εντοπίστηκαν 94 παραδείγματα πολιτισμικών στοιχείων που εντοπίσαμε στο σύνολο του έργου, τα 47 αποτελούν παραδείγματα τοπικών διαλέκτων, 21 αποτελούν παραδείγματα ιδιωτισμών και τα υπόλοιπα 26 είναι παραδείγματα πολιτισμικών αναφορών. Τα παραδείγματα αυτά εξετάζονται στο πλαίσιο της θεώρησης της μετάφρασης ως διαδικασίας λήψης αποφάσεων (Levý 1966, Schäffner 2001), οι οποίες αφορούν τη μεταφραστική στρατηγική και τις μεταφραστικές τεχνικές που χρησιμοποιούνται στην απόδοση του πολιτισμικού στοιχείου στα πολυτροπικά κείμενα που συνιστούν τα κόμικς. Απώτερος στόχος της εργασίας είναι να συνεισφέρει στον διάλογο για τη μετάφραση των κόμικς στα ελληνικά, που ακόμη βρίσκεται, όπως προκύπτει από την ελληνική βιβλιογραφία, σε αρχικό στάδιο, και ακροθιγώς στη συζήτηση για τη διαπολιτισμική μεταφορά πολυτροπικών /πολυσημειωτικών κειμένων εν γένει, στον βαθμό που αυτά πολλαπλασιάζονται ραγδαία στα νέα μέσα.
description: This study aims to record and analyze the rendition of the cultural element, and in particular, dialect elements, idioms and cultural references that are used by the author and comic book artist Don Rosa in the epic fiction novel - biography of the beloved imaginary character, Scrooge McDuck, the "Life and Times of Scrooge McDuck". This text is an ideal example for the study of dialects, idioms and cultural references in connection to their translation and rendition into the Greek language. 94 examples of cultural elements were located, of which 47 are examples of local dialects, 21 are examples of idioms and the remaining 26 are examples of cultural references. These examples are discussed within the framework of translation as a decision-making process (Levý 1966, Schäffner 2001). These decisions have to do with the translation strategy and translation techniques that are used in the rendition of the cultural element in comics as multimodal texts. The ultimate aim of this study is to contribute to the dialogue for the translation of comics in Greek that is still, as it arises from the Greek literature, at an initial stage, and briefly in the discussion about the intercultural transfer of multimodal texts in general, to the extent that these multiply dramatically in new multimedia.

description: Σκοπός της μεταπτυχιακής εργασίας ήταν η σχολιασμένη μετάφραση ενός κειμένου από την ιταλική στην ελληνική γλώσσα. Το κείμενο που επιλέχθηκε να μεταφραστεί είναι απόσπασμα αναφοράς της ψυχολόγου Emily Giovazzino που δημοσιεύτηκε στην ιστοσελίδα της ιταλικής αστυνομίας. Η αναφορά αναλύει το φαινόμενο της εμπορίας ανθρώπων και την εκπόρνευση των μεταναστριών στην Ιταλία. Παράλληλα με τη μετάφραση του αποσπάσματος έγινε μια ανάλυση των δυσκολιών που συναντήθηκαν σε λεξιλογικό, πραγματολογικό και συντακτικό επίπεδο. Δημιουργήθηκε ένα δίγλωσσο γλωσσάρι των όρων του κειμένου και μέρος αυτών αναλύθηκαν μεμονωμένα ώστε να τεκμηριωθούν οι μεταφραστικές επιλογές. Για την ολοκλήρωση της μετάφρασης χρησιμοποιήθηκαν δίγλωσσα και μονόγλωσσα λεξικά, έντυπα και ηλεκτρονικά.
description: The aim of the present thesis was the annotated translation of an Italian text into the Greek language. The chosen text was part of a psychological report by Emily Giovazzino which was published in the webpage of the Italian Police. The report analyses the trafficking phenomenon and the prostitution of immigrant women in Italy. The translation of the text follows an analysis of the difficulties encountered in vocabulary, pragmatic and syntax level. Consequently, a bilingual glossary of the terms was created based on translatological and/or linguistic criteria. Part of the terms extracted where analysed further in order to substantiate the translator’s choices. For the completion of the translation were used both bilingual and monolingual vocabularies as well as printed and online ones.

description: Scattering of neutrons in the 24-150 keV incident energy range from H2O relative to that of D2O and H2O-D2O mixtures was reported very recently. Studying time-of-flight integrated intensities, the applied experimental procedure appears to be transparent and may open up a novel class of neutron experiments regarding the "anomalous" scattering from protons, firstly observed in our experiment at ISIS in the 5-100 eV range. The keV-results were analyzed within standard theory, also including (1) multiple scattering and (2) the strong incident-energy dependence of the neutron-proton cross section in this energy range. The analysis reveals a striking anomalous ratio of scattering intensity of H2O relative to that of D2O of about 20%, thus being in surprisingly good agreement with the earlier results of the original experiment at ISIS.

Puritan iconoclasm : its origin and motivation
Creators: name: Zimmermann, Jens
Publisher: name: University of British Columbia
Year: 2008

description: The thesis examines the debate about iconoclasm during the Protestant Reformation of the sixteenth and seventeenth century by tracing the development of iconoclastic thought from the conflict between Martin Luther and Andreas Bodenstein von Carlstadt (1521/22) through the Swiss Reformers and Jean Calvin up to the time of the English Puritans. Karlstadt's iconoclastic treatises were read in Switzerland and much of their content adopted, defended and refined by men like Leo Jud, Ludwig Haetzer and Ulrich Zwingli. The introduction of Jean Calvin's hermeneutics of synecdoche revolutionized iconoclastic thought, because it increased the weight of the idolatrous offense and also explored the subjective mental aspects of image worship. Secondly, I discuss the reception and adoption of Calvin's synechdocal hermeneutics by the English Puritans to show that the Puritans' uncompromising attitude towards image worship, as well as their call for a consistent application of the ten commandments to every aspect of the social and political spheres of life, is based on Calvin's hermeneutical tool. Furthermore, the connection between image worship, the Eucharist controversy and the Puritan view on music in worship is explored. Attention is also given to the most important analogies and metaphors which were used in the iconoclastic debate, predominantly the equation of unfaithfulness to God and the breaking of His covenant with the violation of the marital covenant through adultery. Because the Puritans' iconoclastic writings and actions were based on their love for God, their motivation for a reconstruction of worship and society ought to be seen as primarily theological, rather than political, and they themselves deserve to he seen not as aesthetic barbarians but as God-fearing men who acted out of a genuine concern for the individual’s as well as for their nation's relationship to God.

description: Magnetic braking is a long-established application of Lenz's law. A rigorous analysis of the laws governing this problem involves solving Maxwell's equations in a time-dependent situation. Approximate models have been developed to describe different experiences related to this phenomenon. In this paper we present a new method for the analysis of the magnetic braking using a magnet fixed to the glider of an air track. The forces acting on the glider, a result of the eddy currents, can be easily observed and measured. As a consequence of the air track inclination, the glider accelerates at the beginning, although it asymptotically tends towards a uniform rectilinear movement characterized by a terminal speed. This speed depends on the interaction between the magnetic field and the conductivity properties of the air track. Compared with previous related approaches, in our experimental setup the magnet fixed to the glider produces a magnetic braking force which acts continuously, rather than over a short period of time. The experimental results satisfactorily concur with the theoretical models adapted to this configuration.

Intensity contrast of solar network and faculae -- II. Implications for solar irradiance modelling

Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We aim to gain insight into the effect of network and faculae on solar irradiance from their apparent intensity. Taking full-disc observations from the Solar Dynamics Observatory, we examined the intensity contrast of network and faculae in the continuum and core of the Fe I 6173 Å line and 1700 Å, including the variation with magnetic flux density, distance from disc centre, nearby magnetic fields, and time. The brightness of network and faculae is believed to be suppressed by nearby magnetic fields from its effect on convection. The difference in intensity contrast between the quiet-Sun network and active region faculae, noted by various studies, arises because active regions are more magnetically crowded and is not due to any fundamental physical differences between network and faculae. These results highlight that solar irradiance models need to include the effect of nearby magnetic fields on network and faculae brightness. We found evidence that suggests that departures from local thermal equilibrium (LTE) might have limited effect on intensity contrast. This could explain why solar irradiance models that are based on the intensity contrast of solar surface magnetic features calculated assuming LTE reproduce the observed spectral variability even where the LTE assumption breaks down. Certain models of solar irradiance employ chromospheric indices as direct indications of the effect of network and faculae on solar irradiance. Based on past studies of the Ca II K line and on the intensity contrast measurements derived here, we show that the fluctuations in chromospheric emission from network and faculae are a reasonable estimate of the emission fluctuations in the middle photosphere, but not of those in the lower photosphere. The data set, which extends from 2010 to 2018, indicates that intensity contrast was stable to about 3% in this period.
On the edge : woman, nature, mother and father in the works of Kono Taeko
Creators: name: Langton, Nina Jean
Publisher: name: University of British Columbia
Year: 2008

description: This thesis examines the works of the contemporary Japanese author, Kono Taeko. In particular, the themes of Nature, Mother and Father, and the manner in which the female protagonists of the works relate to each of these objects, is studied. Within these relationships, issues of fantasy, marginalization, and preoedipal and Oedipal development are also examined. The approach is psychoanalytical, using the relational model rather than classical analysis as the theoretical basis. The first chapter deals with the manner in which the female protagonists relate to the "natural" environment. Some of the similarities and differences in the perception of nature in Japan and the West are pointed out, especially with respect to the way that nature is characterized as being female and maternal. The author is seen as moving from an essentially antagonistic position where nature is perceived as a denying mother-figure to one where nature is regarded as a means of personal liberation and rebirth. Chapter Two focuses on the mother-child relationship and the ambivalent feelings toward mother and motherhood that many women experience. The characters vacillate between a desire tore experience feelings of original unity with the mother, and a desire to cut themselves off from the mother and establish themselves as separate beings. No final resolution in either direction is seen as being reached in these relationships. In the final chapter, the father-daughter relationship is examined, especially with regard to the father's place in the masochistic fantasies of the characters in these works. Furthermore, the father is seen as an idealized figure who acts as a means of escape from the omnipotent mother, but who ironically leads the protagonist back to the mother. The mother-figure, then, lies at the bottom of all of the other major themes in the works of Kono Taeko. These works display an interesting mix of Western and Japanese perceptions of the mother-figure, and the tensions implicit in ambivalent attitudes toward the mother are apparent and make for fruitful study.

We also find the asymptotic expansion of the statistical entropy to first non-leading order in inverse power of charges and show that it agrees with the entropy of a black hole carrying same set of charges after taking into account the effect of the four derivative Gauss-Bonnet term in the effective action of the theory.

description: Inelastic neutron scattering experiments show that spin dynamics in the charge ordered insulating ground state of the double-layer perovskite YBaFe2O5 is well described in terms of eg superexchange interactions. Above the Verwey transition at TV = 308 K, t2g double exchange-type conduction within antiferromagnetic FeO2--BaO--FeO2 double layers proceeds by an electron hopping process that requires a spin flip of the five-fold coordinated Fe ions, costing an energy 5S^2 of approximately 0.1 eV. The hopping process disrupts near-neighbor spin correlations, leading to massive damping of zone-boundary spin waves.

description: The type-III seesaw seems to explain the very minuteness of neutrino masses readily and naturally. The high-energy see-saw theories usually involve a larger number of effective parametres than the physical and measurable parametres appearing in the low-energy neutrino phenomenology. Casas-Ibarra parametrisation facilitates to encode the information lost in integrating the heavy fermions out in an arbitrary complex orthogonal matrix. The CMS collaboration has already searched for triplet fermions in the type-III seesaw model with only one generation of triplet fermion flavour democratically decaying into SM leptons. We reinterpret this CMS search in the context of a realistic type-III seesaw model with two or three generations of triplet fermions, and endeavour to comprehend the implications of the foregoing matrix on the $95\%$ CL lower limit on the mass of the triplet fermions. We also discuss the phenomenological implication of the aforesaid matrix in view of charged lepton flavour violating observables and displaced decays of the triplet fermions at colliders.

description: This article introduces XChronos OS, an ontotechnological operating system based on the symbolic architecture of the XChronos project. Built upon the concepts of Chronons, Hexachronons, Metachronos, and the symbolic function ψ(t), this system redefines the role of time in computation — not as a sequence of clocked intervals, but as a subjective, symbolic flow of consciousness. The XChronos OS proposes a new paradigm where emotional presence, narrative coherence, and ontological reflection become computational resources. The paper explores its philosophical foundations, multi-layered architecture, practical applications, and ethical licensing model for human-centered and conscious-aware systems.

Για τις ανάγκες της εργασίας διενεργήθηκε μια πειραματική μελέτη στην διαφημιστική πλατφόρμα της Google, “Google AdWords”, η οποία είχε ως αντικείμενο την προβολή διαφημιστικών μηνυμάτων για λογαριασμό του Μη Κυβερνητικού Οργανισμού «Καταφύγιο Γυναίκας» που στοχεύει στην προάσπιση των δικαιωμάτων των γυναικών και την ενίσχυσή τους. Μέσω της πειραματικής αυτής μελέτης διερευνήθηκε η αποτελεσματικότητα των διαφόρων τύπων ενοχής σε δύο στοχευμένα κοινά, τα οποία διαχωρίζονται μεταξύ τους βάσει του βαθμού ευαισθητοποίησης που τα διακρίνει σχετικά με το κοινωνικό ζήτημα της κακοποίησης των γυναικών. Τα αποτελέσματα έδειξαν ότι οι «μη ευαισθητοποιημένοι» συμμετέχοντες ανταποκρίθηκαν καλύτερα στις διαφημίσεις που τους προβλήθησαν μέσω του δικτύου της Google, πετυχαίνοντας υψηλότερο δείκτη αναλογίας κλικ προς εμφανίσεων (CTR) συγκριτικά με αυτόν των «ευαισθητοποιημένων», γεγονός μη αναμενόμενο λαμβάνοντας υπόψιν παλαιότερες μελέτες. Όσον αφορά τους διαφόρους τύπους ενοχής, φαίνεται να μην υπάρχει ιδιαίτερη διαφοροποίηση μεταξύ τους.
description: The current thesis, that was drawn as a part of the Interdepartmental Postgraduate Program "Informatics and Management", discusses the guilt emotion in social ads and more specifically in ads that are calling the public to participate in voluntary actions. For the study’s needs there was conducted an experimental study in Google's advertising platform, "Google AdWords", which was designed to display advertisements on behalf of the NGO "Women's Refuge” that aims at defending women's rights and their strengthening. Through this experimental study we investigated the effectiveness of the different types of guilt in two targeted audiences, which have been separated from each other based on the degree of awareness on the social issue of women abuse. The results showed that the “non-sensitized” participants responded better to the advertisements that are shown to them through the Google Network, achieving a higher ratio index click-rate (CTR) compared with the one of the “sensitized” participants, something unexpected considering previous studies. Regarding the different types of guilt, it seems to be no particular distinction between them.

description: 12 Bootis is a spectroscopic binary whose visual orbit has been resolved by interferometry. Though the physical parameters of the system have been determined with an excellent precision, the theoretical modelling of the components is still uncertain. We study the capability of solar-like oscillations to distinguish between calibrated models of the system obtained by including in the stellar modelling different mixing processes. We consider different scenarios for the chemical transport processes: classical overshooting, microscopic diffusion and turbulent mixing. For each of them we calibrate the stellar models of 12 Boo A and B by fitting the available observational constraints by means of a Levenberg-Marquardt minimization algorithm, and finally, we analyze the asteroseismic properties of different calibrated models. Several solutions with 12 Boo A in (or close to) post-main sequence and 12 Boo B on main sequence are found by assuming a thickness of the overshooting layer between 0.06 and 0.23 the pressure scale height. Solutions with both components on the main sequence can be found only by assuming an overshoot larger in the primary than in the secondary, or a more efficient central mixing for 12 Boo A than for 12 Boo B. We show that the detection of solar-like oscillations expected in these stars would allow to distinguish between different scenarios and provide therefore an estimation of the overshooting parameters and of the properties of extra-mixing processes.

description: Considering both the Gauss-Bonnet and the Born-Infeld terms, which are on similar footing with regard to string corrections on the gravity side and electrodynamic side, we present a new class of rotating solutions in Gauss-Bonnet gravity with $k$ rotation parameters in the presence of a nonlinear electromagnetic field. These solutions, which are asymptotically anti-de Sitter in the presence of cosmological constant, may be interpreted as black brane solutions with inner and outer event horizons, an extreme black brane or naked singularity provided the metric parameters are chosen suitably. We calculate the finite action and conserved quantities of the solutions by using the counterterm method, and find that these quantities do not depend on the Gauss-Bonnet parameter. We also compute the temperature, the angular velocities, the electric charge and the electric potential. Then, we calculate the entropy of the black brane through the use of Gibbs-Duhem relation and show that it obeys the area law of entropy. We obtain a Smarr-type formula for the mass as a function of the entropy, the angular momenta and the charge, and show that the conserved and thermodynamic quantities satisfy the first law of thermodynamics. Finally, we perform a stability analysis in both the canonical and grand-canonical ensemble and show that the presence of a nonlinear electromagnetic field has no effect on the stability of the black branes, and they are stable in the whole phase space.

description: We demonstrate the successful application of X-ray Speckle Visibility Spectroscopy (XSVS) experiments to study the dynamics of radiation sensitive, biological samples with unprecedentedly small X-ray doses of 45 Gy and below. Using XSVS, we track the dynamics of casein micelles in native, concentrated, and acidified solution conditions, while substantially reducing the deposited dose as compared to alternative techniques like sequential X-ray photon correlation spectroscopy (XPCS). The Brownian motion in a skim milk sample yields the hydrodynamic radius of the casein micelles while deviations from Brownian motion with a characteristic $q$-dependent diffusion coefficient $D(q)$ can be observed in more concentrated solution conditions. The low dose applied in our experiments allows the observation of static, frozen speckle patterns from gelled acidic milk. We show that the XSVS technique is especially suitable for tracking dynamics of radiation sensitive samples in combination with the improved coherent properties of new generation X-ray sources, emphasizing the great potential for further investigations of protein dynamics using fourth generation synchrotrons and free electron lasers.

description: We demonstrate that the electronic, thermal, and optical properties of a graphene bilayer with boron and nitrogen dopant atoms can be controlled by the interlayer distance between the layers in which the interaction energy and the van der Waals interaction between the dopant atoms play an essential role. We find a conversion of an AA- to an AB-stacked bilayer graphene caused by the repulsive interaction between dopant atoms. At a short interlayer distance, a strong repulsive interaction inducing a strong electric dipole moment of the dopant atoms is found. This gives rise to a breaking of the high symmetry, opening up a bandgap. Consequently, a considerable change in thermoelectric properties such as the Seebeck coefficient and the figure of merit are seen. The repulsive interaction is reduced by increasing the interlayer distance, and at a large interlayer distance the conversion process of the stacking order vanishes. A small bandgap is found leading to a low Seebeck coefficient and a figure of merit. For both short and large interlayer distances, a prominent peak in the optical response is found in the visible range and the peak position is inversely proportional to the interlayer distance.

description: The topological properties of adiabatic gauge fields for multi-level (three-level in particular) quantum systems are studied in detail. Similar to the result that the adiabatic gauge field for SU(2) systems (e.g. two-level quantum system or angular momentum systems, etc) have a monopole structure, the curvature two-forms of the adiabatic holonomies for SU(3) three-level and SU(3) eight-level quantum systems are shown to have monopole-like (for all levels) or instanton-like (for the degenerate levels) structures.

description: Room Temperature Ionic Liquids (RTILs) are molten salts which exhibit uniques physical and chemical properties, commonly harnessed for lubrication and energy applications. The pure ionic nature of RTIL leads to strong electrostatic interactions among the liquid, furthermore exalted in the presence of interfaces and confinement. In this work, we use a tuning-fork based dynamic Surface Force Tribometer (TF-SFT), which allows probing both the rheological and the tribological properties of RTILs films confined between a millimetric sphere and a surface, over a wide range of confinements. When the RTIL is confined between metallic surfaces, we evidence an abrupt change of its rheological properties below a threshold confinement. This is reminiscent of a recently reported confinement induced capillary freezing, here observed with a wide contact area. In parallel, we probe the tribological response of the film under imposed nanometric shear deformation and unveil a yielding behaviour of the interfacial solid phase below this threshold confinement. This is characterized by a transition from an elastic to a plastic regime, exhibiting striking similarities with the response of glassy materials. This transition to yielding of the RTIL in metallic confinement leads overall to a reduction in friction and offers a self-healing protection of the surfaces avoiding direct contact, with obvious applications in tribology.
