description: It is well known that every closed Riemann surface $S$ of genus $g \geq 2$, admitting a group $G$ of conformal automorphisms so that $S/G$ has triangular signature, can be defined over a finite extension of ${\mathbb Q}$. It is interesting to know, in terms of the algebraic structure of $G$, if $S$ can in fact be defined over ${\mathbb Q}$. This is the situation if $G$ is either abelian or isomorphic to $A \rtimes {\mathbb Z}_{2}$, where $A$ is an abelian group. On the other hand, as shown by Streit and Wolfart, if $G = {\mathbb Z}_{p} \rtimes {\mathbb Z}_{q}$ where $p,q>3$ are prime integers, then $S$ is not necessarily definable over ${\mathbb Q}$. In this paper, we observe that if $G={\mathbb Z}_{2}^{2} \rtimes {\mathbb Z}_{m}$ with $m \geq 3$, then $S$ can be defined over ${\mathbb Q}$. Moreover, we describe explicit models for $S$, the corresponding groups of automorphisms and an isogenous decomposition of their Jacobian varieties as product of Jacobians of hyperelliptic Riemann surfaces.

description: We review the recent developments of the polariton physics in microcavities featuring the exciton-photon strong coupling at room-temperature, and leading to the achievement of room-temperature polariton condensates. Such cavities embed active layers with robust excitons that present a large binding energy and a large oscillator strength, i.e. wide bandgap inorganic or organic semiconductors, or organic molecules. These various systems are compared, in terms of figures of merit and of common features related to their strong oscillator strength. The various demonstrations of polariton laser are compared, as well as their condensation phase diagrams. The room-temperature operation indeed allows a detailed investigation of the thermodynamic and out-of-equilibrium regimes of the condensation process. The crucial role of the spatial dynamics of the condensate formation is discussed, as well as the debated issue of the mechanism of stimulated relaxation from the reservoir to the condensate under non-resonant excitation. Finally the prospects of polariton devices are presented.

description: An obstacle for spin-based quantum sensors is magnetic noise due to proximal spins. However, such a spin cluster surrounding the sensor can become an asset, if it can be controlled. Here, we polarize and readout a cluster of three nitrogen (N) electron spins coupled to a single nitrogen-vacancy (NV) spin in diamond. We further achieve sub-nm localization of the cluster spins. Finally, we demonstrate coherent spin exchange between the species by simultaneous dressing of the NV and the N states. These results establish the feasibility of environment-assisted sensing and quantum simulations with diamond spins.

description: We present late-time optical spectroscopy taken with the Large Binocular Telescope's Multi-Object Double Spectrograph, an improved ASAS-SN pre-discovery non-detection, and late-time SWIFT observations of the nearby ($d=193$ Mpc, $z=0.0436$) tidal disruption event (TDE) ASASSN-14ae. Our observations span from $\sim$20 days before to $\sim$750 days after discovery. The proximity of ASASSN-14ae allows us to study the optical evolution of the flare and the transition to a host dominated state with exceptionally high precision. We measure very weak H$α$ emission 300 days after discovery ($L_{\rm Hα} \simeq 4\times 10^{39}$ ergs s$^{-1}$) and the most stringent upper limit to date on the H$α$ luminosity $\sim$750 days after discovery ($L_{\rm Hα} \lesssim 10^{39}$ ergs s$^{-1}$), suggesting that the optical emission arising from a TDE can vanish on a timescale as short as 1 year. Our results have important implications for both spectroscopic detection of TDE candidates at late times, as well as the nature of TDE host galaxies themselves.

description: There is a growing interest for the search of new light gauge bosons. The small mass of a new boson can turn various kinds of low-energy experiments to a new discovery machine, depending on their couplings to the standard model particles. It is important to understand the properties of each type of gauge boson and their current constraints for a given mass. While the dark photon (which couples to the electric charges) and the $U(1)_{B-L}$ gauge boson have been well studied in an extensive mass range, the $U(1)_L$ gauge boson has not been fully investigated yet. We consider the gauge boson of the $U(1)_L$ in a wide mass range $m_{Z'} \approx 0 - 10^{12} ~\ev$ and investigate the constraints on its coupling from various experiments, discussing the similarities and differences from the dark photon and the $U(1)_{B-L}$ gauge boson.

description: Στόχος της παρούσας διπλωματικής εργασίας ήταν η εκτίμηση της προσροφητικής ικανότητας φωσφορικών ιόντων από υδατικά διαλύματα, μέσω τροποποιημένων βιοεξανθρακωμάτων προερχόμενων από αγροτικά υπολείμματα, και πιο συγκεκριμένα κελύφη αμυγδάλου. Τα βιοεξανθρακώματα υποβλήθηκαν σε πυρόλυση σε θερμοκρασίες που κυμαίνονταν από 700 oC έως 750 oC, απουσία οξυγόνου, και στη συνέχεια ενεργοποιήθηκαν με ατμό. Αρχικά, παρασκευάστηκε μη τροποποιημένο βιοεξανθράκωμα μόνο από την βιομάζα. Εν συνεχεία, παρασκευάστηκε τροποποιημένο βιοεξανθράκωμα, το οποίο εμποτίστηκε με MgCl2 και τέλος, παρασκευάστηκαν έξι τροποποιημένα βιοεξανθρακώματα, εκ των οποίων τα δύο προήλθαν από μίξη βιομάζας-μπεντονίτη  σε αναλογία 3:1 και 1:1, και τα άλλα τέσσερα από μίξη βιομάζας-δολομίτη σε αναλογία 19:1, 9:1, 3:1 και 1:1. Για την μελέτη της προσροφητικής ικανότητας των βιοεξανθρακωμάτων, παρασκευάστηκαν υδατικά διαλύματα φωσφορικών ιόντων συγκεντρώσεων: 10, 50, 100, 200, 300 και 400 ppm και αφού ρυθμίστηκε το pH, έγινε ανάμιξη των διαλυμάτων με κάθε προσροφητή σε συγκέντρωση 4 g/L. Η μέτρηση της προσροφημένης ποσότητας PO43- από τα βιοεξανθρακώματα πραγματοποιήθηκε με χρήση χρωματόμετρου (Smart 3 Colorimeter). Τα πειραματικά δεδομένα που προέκυψαν από τη ρόφηση φωσφορικών ιόντων προσαρμόστηκαν στις ισόθερμες Langmuir και Freundlich, με το μοντέλο Langmuir να είναι το επικρατέστερο στην προσομοίωση  των πειραματικών δεδομένων, ενώ από τα αποτελέσματα της φασματοσκοπίας υπέρυθρου μετασχηματισμού Fourier (FTIR), προσδιορίστηκαν οι πιθανοί μηχανισμοί δέσμευσης των φωσφορικών ιόντων. Σύμφωνα με τα πειραματικά δεδομένα, το μη τροποποιημένο δείγμα παρουσίασε τη μικρότερη προσροφητική ικανότητα 27.5 mg/g, ενώ το τροποποιημένο δείγμα με MgCl¬2 κατέγραψε σχεδόν διπλάσια προσροφητική ικανότητα, 58.8 mg/g. Το τροποποιημένο δείγμα με μπεντονίτη 50% ανέδειξε προσροφητική ικανότητα 41 mg/g, ενώ η μεγαλύτερη σημειώθηκε από το τροποποιημένο δείγμα με δολομίτη 10% στα 73 mg/g, σημειώνοντας σε αρκετές περιπτώσεις ποσοστό προσρόφησης φωσφορικών ιόντων 100% από τα υδατικά διαλύματα.

description: We study spatially flat bouncing cosmologies and models with the early-time Genesis epoch in a popular class of generalized Galileon theories. We ask whether there exist solutions of these types which are free of gradient and ghost instabilities. We find that irrespectively of the forms of the Lagrangian functions, the bouncing models either are plagued with these instabilities or have singularities. The same result holds for the original Genesis model and its variants in which the scale factor tends to a constant as $t\to -\infty$. The result remains valid in theories with additional matter that obeys the Null Energy Condition and interacts with the Galileon only gravitationally. We propose a modified Genesis model which evades our no-go argument and give an explicit example of healthy cosmology that connects the modified Genesis epoch with kination (the epoch still driven by the Galileon field, which is a conventional massless scalar field at that stage).

description: We present a proposal of a set-up to measure the work distribution due to an arbitrary unitary process acting on the spatial transverse degrees of freedom of a light beam. Hermite-Gaussian optical modes representing a quantum harmonic oscillator are prepared in a thermal state and sent through an interferometer. We show that the Fourier transform of the work distribution, or the characteristic function, can be obtained by measuring the intensity at the output of the interferometer. The usefulness of the approach is illustrated by calculating the work distribution for a unitary operation that displaces the linear momentum of the oscillator. We discuss the feasibility of the experiment, which can be realized with simple linear optical components.

description: Más de 200 excombatientes de las FARC han sido asesinados en Colombia desde la firma de los acuerdos de paz entre el gobierno y los excombatientes en 2016. La seguridad de estos, es parte integral en el proceso. Cuando los excombatientes se convierten en el blanco de los asesinatos y otras formas de violencia, el proceso de paz en sí está en peligro. Hay muchos debates sobre quién y los motivos por los que están matando a excombatientes de las FARC. La falta de transparencia sobre los casos en los que se han obtenido condenas contribuye a esta incertidumbre, pero se ha identificado a las disidencias de las FARC, los grupos sucesores de los paramilitares y el ELN, como la mayor amenaza. El número de asesinatos de ex-FARC también aumenta cuando los grupos armados están en disputa. Parecería que los asesinatos también están relacionados con el cultivo de coca y el desplazamiento forzado. Quizás lo más significativo es que existen tendencias y similitudes clave entre los asesinatos de líderes sociales y excombatientes de las FARC. Este documento de trabajo mapea la violencia contra los excombatientes y, al hacerlo, destaca algunas tendencias y patrones generales de asesinatos de ex-FARC. Argumentamos que el fenómeno de los asesinatos de ex-FARC está relacionado con el control territorial; proporcionamos evidencia de que los excombatientes de las FARC parecen ser un objetivo directo en los lugares donde se concentran

description: Spherically symmetric dust universe models with a positive cosmological constant $Λ$, known as $Λ$-Lemaître-Tolman-Bondi($Λ$LTB) models, are considered. We report a method to construct the $Λ$LTB model from a given distance-redshift relation observed at the symmetry center. The spherical inhomogeneity is assumed to be composed of growing modes. We derive a set of ordinary differential equations for three functions of the redshift, which specify the spherical inhomogeneity. Once a distance-redshift relation is given, with careful treatment of possible singular points, we can uniquely determine the model by solving the differential equations for each value of $Λ$. As a demonstration, we fix the distance-redshift relation as that of the flat $Λ$CDM model with $(Ω^{\rm dis}_{\rm m0}, Ω^{\rm dis}_{\rm Λ0})=(0.3,0.7)$, where $Ω^{\rm dis}_{\rm m0}$ and $Ω^{\rm dis}_{\rm Λ0}$ are the normalized matter density and the cosmological constant, respectively. Then, we construct the $Λ$LTB model for several values of $Ω_{\rm Λ0}:=Λ/(3H_0^2)$, where $H_0$ is the present Hubble parameter observed at the symmetry center. We obtain void structure around the symmetry center for $Ω_{Λ0}

description: We study the semantic meaning of block structure using game semantics. To that end, we introduce the notion of block-innocent strategies and characterise call-by-value computation with block-allocated storage through soundness, finite definability and universality results. This puts us in a good position to conduct a comparative study of purely functional computation, computation with block storage as well as that with dynamic memory allocation. For example, we can show that dynamic variable allocation can be replaced with block-allocated variables exactly when the term involved (open or closed) is of base type and that block-allocated storage can be replaced with purely functional computation when types of order two are involved. To illustrate the restrictive nature of block structure further, we prove a decidability result for a finitary fragment of call-by-value Idealized Algol for which it is known that allowing for dynamic memory allocation leads to undecidability.

description: The explicit solvability of quantum superintegrable systems is due to symmetry, but the symmetry is often "hidden". The symmetry generators of 2nd order superintegrable systems in 2 dimensions close under commutation to define quadratic algebras, a generalization of Lie algebras. Distinct systems on constant curvature spaces are related by geometric limits, induced by generalized Inönü-Wigner Lie algebra contractions of the symmetry algebras of the underlying spaces. These have physical/geometric implications, such as the Askey scheme for hypergeometric orthogonal polynomials. However, the limits have no satisfactory Lie algebra contraction interpretations for underlying spaces with 1- or 0-dimensional Lie algebras. We show that these systems can be best understood by transforming them to Laplace conformally superintegrable systems, with flat space conformal symmetry group ${\rm SO}(4,{\mathbb C})$, and using ideas introduced in the 1894 thesis of Bôcher to study separable solutions of the wave equation in terms of roots of quadratic forms. We show that Bôcher's prescription for coalescing roots of these forms induces contractions of the conformal algebra $\mathfrak{so}(4,{\mathbb C})$ to itself and yields a mechanism for classifying all Helmholtz superintegrable systems and their limits. In the paper [Acta Polytechnica, to appear, arXiv:1510.09067], we announced our main findings. This paper provides the proofs and more details.

We model FtsZ polymers as active particles moving along chiral, circular paths by Brownian dynamics simulations and a Boltzmann approach. Our two conceptually different methods point to a generic phase behavior. At intermediate particle densities, we find self-organization into vortex structures including closed rings. Moreover, we show that the dynamics at the onset of pattern formation is described by a generalized complex Ginzburg-Landau equation.

description: Recently we have proposed a novel method to probe primordial gravitational waves from upper bounds on the abundance of primordial black holes (PBHs). When the amplitude of primordial tensor perturbations generated in the early Universe is fairly large, they induce substantial scalar perturbations due to their second-order effects. If these induced scalar perturbations are too large when they reenter the horizon, then PBHs are overproduced, their abundance exceeding observational upper limits. That is, primordial tensor perturbations on superhorizon scales can be constrained from the absence of PBHs. In our recent paper we have only shown simple estimations of these new constraints, and hence in this paper, we present detailed derivations, solving the Einstein equations for scalar perturbations induced at second order in tensor perturbations. We also derive an approximate formula for the probability density function of induced density perturbations, necessary to relate the abundance of PBHs to the primordial tensor power spectrum, assuming primordial tensor perturbations follow Gaussian distributions. Our new upper bounds from PBHs are compared with other existing bounds obtained from big bang nucleosynthesis, cosmic microwave background, LIGO/Virgo and pulsar timing arrays.

description: We describe new components of the Gieseker--Maruyama moduli scheme $\mathcal{M}(n)$ of semistable rank 2 sheaves $E$ on $\mathbb{P}^3$ with $c_1(E)=0$, $c_2(E)=n$ and $c_3(E)=0$ whose generic point corresponds to non locally free sheaves. We show that such components grow in number as $n$ grows, and discuss how they intersect the instanton component. As an application, we prove that $\mathcal{M}(2)$ is connected, and identify a connected subscheme of $\mathcal{M}(3)$ consisting of 7 irreducible components.

description: This work is based on a very peculiar chain of ideas, all related to meteors, comets, and any unpredictable objects in space. The title for the whole work was chosen with the nature of meteors and comets in mind. They’re usually alone, their temperament is to follow a path until they either ‘eat’ something (such as eating into the face of a planet or moon), and they’re graceful, dangerous, and wild. Wolves were the perfect metaphor for this. The ‘-Lves’ of Wolves has been altered to ‘lvZ’ to tie the concept back to the earth, quite literally, in that it stands for ‘Low velocity Zone’, a zone within the Earth’s upper mantle which is crucial for absorbing seismic waves.
 I – Spiderling The first step in conceiving a direction of inspiration for this piece began with the discovery of the Spider Crater in Western Australia (16°44′22″S 126°5′25″E). I was looking for interesting Australian meteor impact sites because of an article I had read about the increasingly popular scientific practice of listening and interpreting age-old Aboriginal Legends that have been aurally transmitted from the times in which natural disasters such as meteor strikes, earthquakes, and sudden rises in sea levels occurred. The Spider Crater is inaccessible (except perhaps by helicopter), but it’s landsat image is quite incredible. The first movement, “Spiderling” is based on this curious crater.
 II - Oortian From the Spider Crater, a stunning geological structure created at least 500 million years ago by a meteor impact, we then depart Earth and jump past the solar system to arrive at the Oort Cloud. This sphere of icy objects completely surrounds our solar system and is believed to be the origin of several of the ‘long-period’ comets that we know of. Interference from the nearby passage of a star, nebula, or various actions along the milkyway disk can dislodge cometary nuclei and knock it into our solar system, straight towards the sun. The second movement is titled “Oortian” as ‘being of the Oort Cloud’.
 III - Volarist The final movement in this piece is titled “Volarist”, meaning a ‘flyer’ of sorts. It is inspired by “Ouamama”, the only known interstellar object that has passed through our solar system. It was discovered, already tumbling its way out of the system again, on the 19th October 2017. It’s dark red in colour, and suspected to be either highly elongated or extremely flat in shape. Appearing to our telescopes as only a point source of light, it was difficult to accurately see at the time.

description: ¿Qué posibilidades existen para la industrialización de la hoja de coca? En este informe revisamos la creación de mercados regulados para productos derivados del opio y el cannabis, y discutimos las lecciones aprendidas. Si bien la mayoría de los productos a base de coca son actualmente alimentarios, incluidos tés y bebidas, este informe da un paso más y, basado en las investigaciones científicas más actualizadas, analiza las posibles aplicaciones médicas de la hoja de coca. La investigación preliminar, que aún debe ampliarse significativamente, parece prometedora. Sin embargo, a diferencia del cannabis y el opio, la coca no depende de una gran base de consumidores preexistentes; los incentivos para las empresas son, por tanto, menos importantes que en los demás casos. El informe destaca el papel importante que puede desempeñar el estado en el fomento de la investigación y el desarrollo de productos. En Colombia, el mercado de productos a base de coca está menos desarrollado que en Perú y Bolivia, y los productos que se producen caen en una zona gris legal. Si bien la creación de un mercado regulado y la industrialización de la hoja de coca no serían una respuesta al problema del cultivo de drogas ilícitas en Colombia, podría permitir la entrada al mercado de un nuevo producto agrícola, con potencial para la creación de bienes de valor agregado con aplicaciones médicas. Sin embargo, antes de que esto pueda hacerse en Colombia, es necesario superar una serie de obstáculos legales y políticos

description: Topological Weyl semimetals can host Weyl nodes with monopole charges in momentum space. How to detect the signature of the monopole charges in quantum transport remains a challenging topic. Here, we reveal the connection between the parity of monopole charge in topological semimetals and the quantum interference corrections to the conductivity. We show that the parity of monopole charge determines the sign of the quantum interference correction, with odd and even parity yielding the weak anti-localization and weak localization effects, respectively. This is attributed to the Berry phase difference between time-reversed trajectories circulating the Fermi sphere that encloses the monopole charges. From standard Feynman diagram calculations, we further show that the weak-field magnetoconductivity at low temperatures is proportional to $+\sqrt{B}$ in double-Weyl semimetals and $-\sqrt{B}$ in Weyl semimetals, respectively, which could be verified experimentally.
