description: Assuming an array that consists of two parallel lines of qubits and that permits only nearest neighbor interactions, we construct physical and logical circuitry to enable universal fault tolerant quantum computation under the [[7,1,3]] quantum code. A rigorous lower bound to the fault tolerant threshold for this array is determined in a number of physical settings. Adversarial memory errors, two-qubit gate errors, and readout errors are included in our analysis. In the setting where the physical memory failure rate is equal to one-tenth of the physical gate error rate, the physical readout error rate is equal to the physical gate error rate, and the duration of physical readout is ten times the duration of a physical gate, we obtain a lower bound to the asymptotic threshold of 1.96x10^-6.

description: We investigate the spin-polarized transport properties of a two-dimensional electron gas in a n-type diluted magnetic narrow gap semiconductor quantum well subjected to a perpendicular magnetic and electric field. Interesting beating patterns in the magneto resistance are found which can be tuned significantly by varying the electric field. A resonant enhancement of spin-polarized current is found which is induced by the competition between the s-d exchange interaction and the Rashba effect [Y. A. Bychkov and E. I. Rashba, J. Phys. C 17, 6039 (1984)].

description: Στην εργασία αυτή θα εστιάσουμε το ενδιαφέρον μας στο πρόβλημα Learning With Errors (LWE) (κεφ. 2). Το συγκεκριμένο πρόβλημα είναι αποδεδειγμένα ανθεκτικό όσο κάποια προβλήματα με πλέγματα στην χειρότερη περίπτωσή τους. Επίσης, παρ’όλη την θεωρητική ανθεκτικότητα του προβλήματος, βασισμένοι στην βιβλιογραφία αναλύουμε τις δυο κυριότερες κατηγορίες πρακτικών επιθέσεων στο LWE (κεφ. 3). Στην συνέχεια παρουσιάζουμε ένα από τα πιο υποσχόμενα ομομορφικά κρυπτοσυστήματα. Το κρυπτοσύστημα αυτό είναι βασισμένο στο LWE πρόβλημα, καθώς και σε μια παραλλαγή του LWE πάνω σε δακτύλιους πολυωνύμων (κεφ. 4).
description: In the present thesis, we study the LWE problem (chapter 2). This particular problem is provably as hard as worst-case lattice problems. In spite of its theoretical resistance, we analyze the most promising attacks on LWE, using the reduction into the SIS and BDD problems (chapter 3). Finally, we present one of the most promising homomorphic cryptosystems, the BGV cryptosystem, based on the LWE problem and its variant over polynomial rings (chapter 4).

description: Σκοπός της παρούσας μελέτης ήταν να εξεταστούν οι παράγοντες που συνηγορούν στην ανάδειξη των ψυχικά ασθενών ως καλλιτέχνες. Αρχικά μελετήσαμε την εικονογραφία της τέχνης του περιθωρίου, αλλά και το ιστορικό υπόβαθρο αυτής, μέσα από αναφορές σε εμβληματικούς ασθενείς/ καλλιτέχνες. Μας απασχόλησε επιπροσθέτως, η σχέση της ιδιοφυίας με την ψυχική ασθένεια, και η σύνδεση της τέχνης του περιθωρίου με τον μοντερνισμό. Ακολούθως, αναφερθήκαμε στα μέσα με τα οποία η τέχνη του περιθωρίου εντάσσεται στον παγκόσμιο κόσμο της τέχνης, αλλά και στον ελληνικό ειδικότερα. Μέσα από παραδείγματα μουσείων, εκθέσεων και κέντρων τέχνης επιχειρήσαμε να δώσουμε μια συνολική εικόνα των φορέων που έχουν στρέψει το ενδιαφέρον τους στα έργα των ψυχικά ασθενών και να ερευνήσουμε το κατά πόσο οι φορείς αυτοί με την σειρά τους έχουν επηρεάσει την τέχνη του περιθωρίου
description: The aim of this thesis was to examine the factors that support the emergence of mental patients as artists. Initially we studied the iconography of art brut, and its historical background, through references to emblematic patients/ artists. We also touched on the relationship between genius and mental illness, and the connection between art brut and modernism. Subsequently, we referred to sectors which contribute to art brut being part of global world of art, but also of the Greek one in particular. Through examples of museums, exhibitions and art centers, we have attempted to give a general display of the factors who are interested in works of mental patients and to consider whether these factors have influenced art brut

description: An interesting twist of the Hirsch index is given, in terms of an index for topics and compounds. By comparing both the hb index and m for a number of compounds and topics, it can be used to differentiate between a new so-called hot topic with older topics. This quick method is shown to help new comers to identify how much interest and work has already been achieved in their chosen area of research.

description: The present paper tries to connect Βrecht’s theory and methods with the principles and the targets of the environmental education, as a proposal for a modern approach. Trying to figure out what Βrecht can offer, as a pedagogue, in environmental education, we analyze shortly a few pedagogical theories and approaches which are related to Brecht’s philosophy, but also to environmental education. In the paper are presented: education through arts, educational theatre, experiential education, critical pedagogy, education of the citizen and environmental education. Afterwards, the method and the theory of the epic theatre of Brecht are also presented. In the conclusions, is proved the close relation between environmental education and Brecht, their common targets, principles and values. Brecht’s theoretical and practical work can offer a lot in environmental education as an educational tool, mostly in the development of positive environmental attitudes, values and skills, such as empathy, the development of critical thought, the undertaking of initiatives and the solution of the problems, by showing solidarity to the fellow man, by changing behavior and all these in a creative, team, experiential and sustainable way.

description: Non-minimal interactions in the pp-wave Einstein - Yang - Mills - Higgs (EYMH) model are shown to give rise to color cross-effects analogous to the magneto-electricity in the Maxwell theory. In order to illustrate the significance of these color cross-effects, we reconstruct the effective (associated, color and color-acoustic) metrics for the pp-wave non-minimal seven-parameter EYMH model with parallel gauge and scalar background fields. Then these metrics are used as hints for obtaining explicit exact solutions of the non-minimally extended Yang-Mills and Higgs equations for the test fields propagating in the vacuum interacting with curvature. The influence of the non-minimal coupling on the test particle motion is interpreted in terms of the so-called trapped surfaces, introduced in the Analog Gravity theory.

description: We investigate the entanglement entropy (EE) and charge fluctuations in models where the low energy physics is governed by massless Dirac fermions. We focus on the response to flux insertion which, for the EE, is widely assumed to be universal, \emph{i.e.}, independent of the microscopic details. We provide an analytical derivation of the EE and charge fluctuations for the seminal example of graphene, using the dimensional reduction of its tight-binding model to the one-dimensional Su-Schrieffer-Heeger model. Our asymptotic expression for the EE matches the conformal field theory prediction. We show that the charge variance has the same asymptotic behavior, up to a constant prefactor. To check the validity of universality arguments, we numerically consider several models, with different geometries and number of Dirac cones, and either for strictly two-dimensional models or for gapless surface mode of three-dimensional topological insulators. We also show that the flux response does not depend on the entangling surface geometry as long as it encloses the flux. Finally we consider the universal corner contributions to the EE. We show that in the presence of corners, the Kitaev-Preskill subtraction scheme provides non-universal, geometry dependent results.

description: In a recent paper [J. Math. Phys. 47 082303 (2006)], Quantum Energy Inequalities were used to place simple geometrical bounds on the energy densities of quantum fields in Minkowskian spacetime regions. Here, we refine this analysis for massive fields, obtaining more stringent bounds which decay exponentially in the mass. At the technical level this involves the determination of the asymptotic behaviour of the lowest eigenvalue of a family of polyharmonic differential equations, a result which may be of independent interest. We compare our resulting bounds with the known energy density of the ground state on a cylinder spacetime. In addition, we generalise some of our technical results to general $L^p$-spaces and draw comparisons with a similar result in the literature.

description: Illuminating or imaging samples from a broad angular range is essential in a wide variety of computational 3D imaging and resolution-enhancement techniques, such as optical projection tomography (OPT), optical diffraction tomography (ODT), synthetic aperture microscopy, Fourier ptychographic microscopy (FPM), structured illumination microscopy (SIM), photogrammetry, and optical coherence refraction tomography (OCRT). The wider the angular coverage, the better the resolution enhancement or 3D resolving capabilities. However, achieving such angular ranges is a practical challenge, especially when approaching plus-or-minus 90 degrees or beyond. Often, researchers resort to expensive, proprietary high numerical aperture (NA) objectives, or to rotating the sample or source-detector pair, which sacrifices temporal resolution or perturbs the sample. Here, we propose several new strategies for multi-angle imaging approaching 4pi steradians using concave parabolic or ellipsoidal mirrors and fast, low rotational inertia scanners, such as galvanometers. We derive theoretically and empirically relations between a variety of system parameters (e.g., NA, wavelength, focal length, telecentricity) and achievable fields of view (FOVs) and importantly show that intrinsic tilt aberrations do not restrict FOV for many multi-view imaging applications, contrary to conventional wisdom. Finally, we present strategies for avoiding spherical aberrations at obliquely illuminated flat boundaries. Our simple designs allow for high-speed multi-angle imaging for microscopic, mesoscopic, and macroscopic applications.

Τα συμπτώματα των μαθησιακών δυσκολιών δεν εμφανίζονται με τον ίδιο τρόπο και στην ίδια ηλικία σε κάθε παιδί, γι’ αυτό και είναι ποίκιλλες και διαφορετικές οι σχετικές προσεγγίσεις. Στην παρούσα μελέτη τα ερευνητικά ερωτήματα που διερευνούνται αφορούν σε μικτή μεθοδολογία με την χρήση των εργαλείων της συνέντευξης και του ερωτηματολογίου. Συγκεκριμένα λήφθηκαν τέσσερις συνεντεύξεις από καθηγήτριες της γαλλικής γλώσσας ενός ιδιωτικού σχολείου της Θεσσαλονίκης ενώ συλλέχθηκαν και 104 ερωτηματολόγια από καθηγητές/τριες της γαλλικής γλώσσας. Συμφώνα με τα αποτελέσματα οι κυρίαρχες τέσσερις μαθησιακές δυσκολίες είναι η δυσλεξία, η ΔΕΠΥ, ο αυτισμός και η νόσος του Asperger. Τέλος, πρέπει να τονιστεί ότι τα δεδομένα που αντλήθηκαν από τις απαντήσεις των ερωτηθέντων δίνουν σημαντικές απαντήσεις στα ερευνητικά ερωτήματα που έχουν τεθεί.
description: This thesis focuses on the learning difficulties faced by children in French language as a second foreign language, but also on the role of the teacher with the approaches he may use. Learning difficulties prevent a child’s proper developing and impede οn the activities of his / her everyday life because several of them have a significant impact on oral and written speech as well as on his / her social life. The symptoms of learning difficulties do not appear in the same way and at the same age in each child, so the variations of those problems and the approaches are many and different. In the present study, the research questions that are being investigated concern a mixed methodology using the tools of the interview and the questionnaire. Specifically, four interviews were held by teachers from the French language of a private school in Thessaloniki and 104 questionnaires were collected from French language teachers. According to the results, the four prevailing learning difficulties are dyslexia, ADHD, autism and Asperger's disease. Ιn conclusion, that the data obtained from respondents' answers give important answers to the research questions that have been asked.

Η μελέτη του φαινόμενου αυτού πραγματοποιήθηκε με τη χρήση ενός μαθηματικού μοντέλου, το οποίο κατασκευάστηκε για το σκοπό αυτόν. Η λωρίδα του αγρού θεωρήθηκε ανοικτός αγωγός μεγάλου πλάτους και ομοιόμορφης κλίσης, με υδραυλικά περατό πυθμένα. Η προσομοίωση της ροής στην επιφάνεια του εδάφους έγινε με τη χρησιμοποίηση των εξισώσεων του Saint-Venant, ενώ η προσομοίωση της διήθησης στην επιφάνεια του εδάφους έγινε με τη χρησιμοποίηση της εξίσωσης του Richards. Τόσο οι εξισώσεις του Saint-Venant όσο και η εξίσωση του Richards επιλύθηκαν αριθμητικά. Η αριθμητική επίλυση των εξισώσεων αυτών έγινε με τη χρησιμοποίηση του ρητού υπολογιστικού σχήματος MacCormack, το οποίο προσεγγίζει τις παραγώγους με τη χρησιμοποίηση πεπερασμένων διαφορών και λειτουργεί σε δύο βήματα –ένα βήμα πρόβλεψης και ένα βήμα διόρθωσης. Ακόμη, εξετάστηκε η επίδραση διάφορων παραμέτρων στο φαινόμενο της επιφανειακής απορροής, όπως η τραχύτητα της επιφάνειας του εδάφους και η αρχική υγρασιακή κατάσταση του εδάφους, καθώς και η κλίση και το μήκος της λωρίδας του αγρού
description: The aim of the present thesis was the study of the surface runoff from fields irrigated by surface irrigation methods, caused by a rainfall episode. The study of this phenomenon was realized using a mathematical model, which was constructed for this purpose. Τhe overland flow was considered to be an open-channel flow. The field lane was considered to be an open channel with a free-surface width much greater than the depth of flow, with a uniform bottom slope and with a hydraulically permeable bottom. The overland flow was simulated using the Saint-Venant equations, while the infiltration through the soil surface was simulated using the Richards equation. The Saint-Venant equations, as well as the Richards equation, were solved numerically. The numerical solution of these equations was obtained using the MacCormack explicit computational scheme, which approaches derivatives using finite differences and operates in two steps - a predictor step and a corrector step. In addition, the effect of various parameters on the phenomenon of surface runoff was examined. These parameters were the soil surface roughness, the initial soil moisture, the slope and the length of the field lane

description: On 4 July 2005 at 5:52 UT the Deep Impact mission successfully completed its goal to hit the nucleus of 9P/Tempel 1 with an impactor, forming a crater on the nucleus and ejecting material into the coma of the comet. NASA's Submillimeter Wave Astronomy Satellite (SWAS) observed the 1(10)-1(01) ortho-water ground-state rotational transition in comet 9P/Tempel 1 before, during, and after the impact. No excess emission from the impact was detected by SWAS and we derive an upper limit of 1.8e7 kg on the water ice evaporated by the impact. However, the water production rate of the comet showed large natural variations of more than a factor of three during the weeks before and after the impact.

description: Quantum computers have the potential to help solve a range of physics and chemistry problems, but noise in quantum hardware currently limits our ability to obtain accurate results from the execution of quantum-simulation algorithms. Various methods have been proposed to mitigate the impact of noise on variational algorithms, including several that model the noise as damping expectation values of observables. In this work, we benchmark various methods, including a new method proposed here. We compare their performance in estimating the ground-state energies of several instances of the 1D mixed-field Ising model using the variational-quantum-eigensolver algorithm with up to 20 qubits on two of IBM's quantum computers. We find that several error-mitigation techniques allow us to recover energies to within 10% of the true values for circuits containing up to about 25 ansatz layers, where each layer consists of CNOT gates between all neighboring qubits and Y-rotations on all qubits.

description: Topological phases with broken time-reversal symmetry and Chern number |C|>=2 are of fundamental interest, but it remains unclear how to engineer the desired topological Hamiltonian within the paradigm of spin-orbit-coupled particles hopping only between nearest neighbours of a static lattice. We show that phases with higher Chern number arise when the spin-orbit coupling satisfies a combination of spin and spatial rotation symmetries. We leverage this result both to construct minimal two-band tight binding Hamiltonians that exhibit |C|=2,3 phases, and to show that the Chern number of one of the energy bands can be inferred from the particle spin polarization at the high-symmetry crystal momenta in the Brillouin zone. Using these insights, we provide a detailed experimental scheme for the specific realization of a time-reversal-breaking topological phase with |C|=2 for ultracold atomic gases on a triangular lattice subject to spin-orbit coupling. The Chern number can be directly measured using Zeeman spectroscopy; for fermions the spin amplitudes can be measured directly via time of flight, while for bosons this is preceded by a short Bloch oscillation. Our results provide a pathway to the realization and detection of novel topological phases with higher Chern number in ultracold atomic gases.

description: The effects of thermal elastic fluctuations in rubber materials are examined. It is shown that, due to an interplay with the incompressibility constraint, these fluctuations qualitatively modify the large-deformation stress-strain relation, compared to that of classical rubber elasticity. To leading order, this mechanism provides a simple and generic explanation for the peak structure of Mooney-Rivlin stress-strain relation, and shows a good agreement with experiments. It also leads to the prediction of a phonon correlation function that depends on the external deformation.

description: The high-order statistics of fluctuations in velocity gradients in the crossover range from the inertial to the Kolmogorov and sub-Kolmogorov scales are studied by direct numerical simulations (DNS) of homogeneous isotropic turbulence with vastly improved resolution. The derivative moments for orders 0 <= n <= 8 are represented well as powers of the Reynolds number, Re, in the range 380 <= Re <= 5725, where Re is based on the periodic box length L_x. These low-Reynolds-number flows give no hint of scaling in the inertial range even when extended self-similarity is applied. Yet, the DNS scaling exponents of velocity gradients agree well with those deduced, using a recent theory of anomalous scaling, from the scaling exponents of the longitudinal structure functions at infinitely high Reynolds numbers. This suggests that the asymptotic state of turbulence is attained for the velocity gradients at far lower Reynolds numbers than those required for the inertial range to appear. We discuss these findings in the light of multifractal formalism. Our numerical studies also resolve the crossover of the velocity gradient statistics from the Gaussian to non-Gaussian behaviour that occurs as the Reynolds number is increased.

description: This work analyzes correlations arising from quantum systems subject to sequential projective measurements to certify that the system in question has a quantum dimension greater than some $d$. We refine previous known methods and show that dimension greater than two can be certified in scenarios which are considerably simpler than the ones presented before and, for the first time in this sequential projective scenario, we certify quantum systems with dimension strictly greater than three. We also perform a systematic numerical analysis in terms of robustness and conclude that performing random projective measurements on random pure qutrit states allows a robust certification of quantum dimensions with very high probability.

Can a double stranded DNA be unzipped by pulling a single strand?: Phases of adsorbed DNA

description: We study the unzipping of a double stranded DNA (dsDNA) by applying an external force on a single strand while leaving the other strand free. We find that the dsDNA can be unzipped to two single strands if the external force exceeds a critical value. We obtain the phase diagram which is found to be different from the phase diagram of unzipping by pulling both the strands in opposite directions. In the presence of an attractive surface near DNA, the phase diagram gets modified drastically and shows richer surprises including a critical end point and a triple point.

description: We describe a non-perturbative quantization of classical Wilson loops in the WZW model. The quantized Wilson loop is an operator acting on the Hilbert space of closed strings and commuting either with the full Kac-Moody chiral algebra or with one of its subalgebras. We prove that under open/closed string duality, it is dual to a boundary perturbation of the open string theory. As an application, we show that such operators are useful tools for identifying fixed points of the boundary renormalization group flow.

description: Freyd's generating hypothesis, interpreted in the stable module category of a finite p-group G, is the statement that a map between finite-dimensional kG-modules factors through a projective if the induced map on Tate cohomology is trivial. We show that Freyd's generating hypothesis holds for a non-trivial finite p-group G if and only if G is either C_2 or C_3. We also give various conditions which are equivalent to the generating hypothesis.

Bayesian estimation of our local motion from the Planck-2018 CMB temperature map

description: The largest fluctuation in the CMB sky is the CMB dipole, which is believed to be caused by the motion of our observation frame with respect to the CMB rest frame. This motion accounts for the known motion of the Solar System barycentre with a best-fit amplitude of $369$ km/s, in the direction ($\ell= 264^\circ$, $b=48^\circ$) in galactic coordinates. Along with the CMB dipole signal, this motion also causes an inevitable signature of statistical anisotropy in the higher multipoles due to the modulation and aberration of the CMB temperature and polarization fields. This leads to a correlation between adjacent CMB multipoles causing a non-zero value of the off-diagonal terms in the covariance matrix which can be captured in terms of the dipolar spectra of the bipolar spherical harmonics (BipoSH). In our work, we jointly infer the CMB power spectrum and the BipoSH spectrum in a Bayesian framework using the $\textit{Planck}$-2018 $\texttt{SMICA}$ temperature map. We detect amplitude and direction of the local motion consistent with the canonical value $v=369$ km/s inferred from CMB dipole with a statistical significance of $4.54σ$, $4.97σ$ and $5.23σ$ respectively from the masked temperature map with the available sky fraction $40.1\%$, $59.1\%$, and $72.2\%$, confirming the common origin of both the signals. The Bayes factor in favor of the canonical value is between $7$ to $8$ depending on the choice of mask. But it strongly disagrees (by a value of the Bayes factor about $10^{-10}-10^{-11}$) with a higher value of local motion which one can infer from the amplitude of the dipole signal obtained from the CatWISE2020 quasar catalog using the WISE and NEOWISE data set.

Scalar and fermion on-shell amplitudes in generalized Higgs effective field theory

description: Beyond standard model (BSM) particles should be included in effective field theory in order to compute the scattering amplitudes involving these extra particles. We formulate an extension of Higgs effective field theory which contains arbitrary number of scalar and fermion fields with arbitrary electric and chromoelectric charges. The BSM Higgs sector is described by using the non-linear sigma model in a manner consistent with the spontaneous electroweak symmetry breaking. The chiral order counting rule is arranged consistently with the loop expansion. The leading order Lagrangian is organized in accord with the chiral order counting rule. We use a geometrical language to describe the particle interactions. The parametrization redundancy in the effective Lagrangian is resolved by describing the on-shell scattering amplitudes only with the covariant quantities in the scalar/fermion field space. We introduce a useful coordinate (normal coordinate), which simplifies the computations of the on-shell amplitudes significantly. We show the high energy behaviors of the scattering amplitudes determine the "curvature tensors" in the scalar/fermion field space. The massive spinor-wavefunction formalism is shown to be useful in the computations of on-shell helicity amplitudes.

On the decidability and complexity of Metric Temporal Logic over finite words

description: Metric Temporal Logic (MTL) is a prominent specification formalism for real-time systems. In this paper, we show that the satisfiability problem for MTL over finite timed words is decidable, with non-primitive recursive complexity. We also consider the model-checking problem for MTL: whether all words accepted by a given Alur-Dill timed automaton satisfy a given MTL formula. We show that this problem is decidable over finite words. Over infinite words, we show that model checking the safety fragment of MTL--which includes invariance and time-bounded response properties--is also decidable. These results are quite surprising in that they contradict various claims to the contrary that have appeared in the literature.
