description: In unserer modernen Gesellschaft führt die rasant steigende Nutzung digitaler Technologien zu kontinuierlich steigenden Anforderungen an die Kapazität von Übertragungssystemen. In Weitverkehrssystemen haben Lichtwellenleiter andere Technologien fast vollständig verdrängt, wobei Weiterentwicklungen den steigenden Anforderungen Rechnung tragen müssen. Vielversprechend sind in diesem Kontext Raummultiplexsysteme. In der vorliegenden Arbeit wird das Potenzial des Modenmultiplexbetriebs zur Steigerung der Übertragungskapazität optischer Datenübertragungssysteme analysiert. In Fasern, in denen mehrere Moden ausbreitungsfähig sind, kann die Übertragungskapazität durch Nutzung der räumlichen Diversität gesteigert werden. Für Glasfasern als ein nichtlineares Medium konnte die Frage, ob die Kapazität um den Faktor genutzter Moden erhöht werden kann, in der Vergangenheit nicht beantwortet werden. Um das Potenzial von Modenmultiplexsystemen zur Kapazitätssteigerung bewerten zu können wird untersucht, wie die nichtlinearen Effekte und die daraus resultierende Signaldegradation mit der Modenanzahl skalieren. Da eine analytische Berechnung der Ausbreitung optischer Wellen in Glasfasern im Allgemeinen nicht möglich ist, werden numerische Methoden zur Untersuchung verwendet. Entwickelt wurden hochperformante GPU-beschleunigte Algorithmen, um notwendige Simulationen in einer akzeptablen Zeit durchführen zu können. Neben den Untersuchungen zur Skalierung der nichtlinearen Effekte in Mehrmodenfasern, wird daher auch die numerische Simulation im Allgemeinen und die effiziente, hochparallele Implementierung der Simulationsmethoden behandelt. In der Arbeit wird gezeigt, dass der Modenmultiplexbetrieb eine hoch skalierbare Option zur Steigerung der Übertragungskapazität einer einzelnen Faser darstellt und sich Mehrmodenfasern mit mehr als 100 räumlichen Moden zur Datenübertragung nutzen lassen.

Coupling active and sterile neutrinos in the cosmon plus seesaw framework

description: The cosmological evolution of neutrino energy densities driven by cosmon-type field equations is introduced assuming that active and sterile neutrinos are intrinsically connected by cosmon fields through the {\em seesaw} mechanism. Interpreting sterile neutrinos as dark matter adiabatically coupled with dark energy results in a natural decoupling of (active) mass varying neutrino (MaVaN) equations. Identifying the dimensionless scale of the {\em seesaw} mechanism, $m/M$, with a power of the cosmological scale factor, $a$, allows for embedding the resulting masses into the generalized Chaplygin gas (GCG) scenario for the dark sector. Without additional assumptions, our findings establish a precise connection among three distinct frameworks: the cosmon field dynamics for MaVaN's, the {\em seesaw} mechanism for dynamical mass generation and the GCG scenario. Our results also corroborate with previous assertions that mass varying particles can be the right responsible for the stability issue and for the cosmic acceleration of the universe.

description: Focusing light represents one of the fundamental optical functionalities that is used in a countless number of situations. Here we introduce the concept of nano-bore optical fiber mediated light focusing that allows to efficiently focus light at micrometer distance from the fiber end face. Since the focusing effect is provided by the fundamental fiber mode, device implementation is extremely straightforward since no post-processing or nano-structuring is necessary. Far-field measurements on implemented fibers, simulations, and a dual-Gaussian beam toy model confirm the validity of the concept. Due to its unique properties such as strong light localization, a close to 100% implementation success rate, extremely high reproducibility, and its compatibility with current fiber circuitry, the concept will find application in numerous areas that demand to focus at remote distances.

description: Topological insulators (TIs) gained high interest due to their protected electronic surface states that allow dissipation-free electron and information transport. In consequence, TIs are recommended as materials for spintronics and quantum computing. Yet, the number of well-characterized TIs is rather limited. To contribute to this field of research, we focused on new bismuth-based subiodides and recently succeeded in synthesizing a new compound Bi12Rh3Sn3I9, which is structurally closely related to Bi14Rh3I9 – a stable, layered material. In fact, Bi14Rh3I9 is the first experimentally supported weak 3D TI. Both structures are composed of well-defined intermetallic layers of ∞2[(Bi4Rh)3I]2+ with topologically protected electronic edge-states. The fundamental difference between Bi14Rh3I9 and Bi12Rh3Sn3I9 lies in the composition and the arrangement of the anionic spacer. While the intermetallic 2D TI layers in Bi14Rh3I9 are isolated by ∞1[Bi2I8]2− chains, the isoelectronic substitution of bismuth(III) with tin(II) leads to ∞2[Sn3I8]2− layers as anionic spacers. First transport experiments support the 2D character of this material class and revealed metallic conductivity. © 2020 The Authors. Published by Wiley-VCH GmbH

description: Recent experiments on strongly coupled cavity quantum electrodynamics present new directions in "matter-light" systems. Following on from our previous work [Phys. Rev. Lett. 102, 135301 (2009)] we investigate Bose-Hubbard models coupled to a cavity light field. We discuss the emergence of photoexcitations or "polaritons" within the Mott phase, and obtain the complete variational phase diagram. Exploiting connections to the super-radiance transition in the Dicke model we discuss the nature of polariton condensation within this novel state. Incorporating the effects of carrier superfluidity, we identify a first-order transition between the superradiant Mott phase and the single component atomic superfluid. The overall predictions of mean field theory are in excellent agreement with exact diagonalization and we provide details of superfluid fractions, density fluctuations, and finite size effects. We highlight connections to recent work on coupled cavity arrays.

description: The substitution of scandium in fullerene single-molecule magnets (SMMs) DySc2N@C80 and Dy2ScN@C80 by lutetium has been studied to explore the influence of the diamagnetic metal on the SMM performance of dysprosium nitride clusterfullerenes. The use of lutetium led to an improved SMM performance of DyLu2N@C80, which shows a higher blocking temperature of magnetization (TB=9.5 K), longer relaxation times, and broader hysteresis than DySc2N@C80 (TB=6.9 K). At the same time, Dy2LuN@C80 was found to have a similar blocking temperature of magnetization to Dy2ScN@C80 (TB=8 K), but substantially different interactions between the magnetic moments of the dysprosium ions in the Dy2MN clusters. Surprisingly, although the intramolecular dipolar interactions in Dy2LuN@C80 and Dy2ScN@C80 are of similar strength, the exchange interactions in Dy2LuN@C80 are close to zero. Analysis of the low-frequency molecular and lattice vibrations showed strong mixing of the lattice modes and endohedral cluster librations in k-space. This mixing simplifies the spin–lattice relaxation by conserving the momentum during the spin flip and helping to distribute the moment and energy further into the lattice. © 2019 The Authors.

Theory versus experiment for vacuum Rabi oscillations in lossy cavities

description: The 1996 Brune {\it et al.} experiment on vacuum Rabi oscillation is analyzed by means of alternative models of atom-reservoir interaction. Agreement with experimental Rabi oscillation data can be obtained if one defines jump operators in the dressed-state basis, and takes into account thermal fluctuations between dressed states belonging to the same manifold. Such low-frequency transitions could be ignored in a closed cavity, but the cavity employed in the experiment was open, which justifies our assumption. The cavity quality factor corresponding to the data is $Q=3.31\cdot 10^{10}$, whereas $Q$ reported in the experiment was $Q=7\cdot 10^7$. The rate of decoherence arising from opening of the cavity can be of the same order as an analogous correction coming from finite time resolution $Δt$ (formally equivalent to collisional decoherence). Peres-Horodecki separability criterion shows that the rate at which the atom-field state approaches a separable state is controlled by fluctuations between dressed states from the same manifold, and not by the rate of transitions towards the ground state. In consequence, improving the $Q$ factor we do not improve the coherence properties of the cavity.

This validation is made by RMI and integrates two aspects. First, a human operator routinely monitors the data on successive periods of 24 hours. Issues detected on that daily timeframe are directly corrected. Second, monthly and annual values from the validated HIC data are compared against neighboring stations data as well as radar-derived rainfall estimates. Both validation aspects are treated in this report.

description: We study the properties of QCD at high baryon density in a finite volume where color superconductivity occurs. We derive exact sum rules for complex eigenvalues of the Dirac operator at finite chemical potential, and show that the Dirac spectrum is directly related to the color superconducting gap $Δ$. Also, we find a characteristic signature of color superconductivity: an X-shaped spectrum of partition function zeros in the complex quark mass plane near the origin, reflecting the $Z(2)_{L} \times Z(2)_{R}$ symmetry of the diquark pairing. Our results are universal in the domain $Δ^{-1} \ll L \ll m_π^{-1}$ where $L$ is the linear size of the system and $m_π$ is the pion mass at high density.

description: A new coordinate system is defined for the Four-Body dynamical problem with general masses, having as its origin of coordinates the center of mass. The transformation from the inertial coordinate system involves a combination of a rotation to the principal axis of inertia, followed by three changes of scale leading the principal moments of inertia to yield a body with three equal moments of inertia, and finally a second rotation that leaves unaltered the equal moments of inertia. These three transformations yield a mass-dependent rigid orthogonal tetrahedron of constant volume in the inertial coordinates. Each of those three linear transformations is a function of three coordinates that produce the nine degrees of freedom of the Four-Body problem, in a coordinate system with the center of mass as origin. The relation between the well known equilateral tetrahedron solution of the gravitational Four-Body problem and the new coordinates is exhibited, and the plane case of central configurations with four different masses is computed numerically in these coordinates.

description: Fluorescence correlation spectroscopy in combination with super-resolution stimulated emission depletion microscopy (STED-FCS) is a powerful tool to investigate molecular diffusion with sub-diffraction resolution. It has been of particular use for investigations of two dimensional systems like cell membranes, but has so far seen very limited applications to studies of three-dimensional diffusion. One reason for this is the extreme sensitivity of the axial (z) STED depletion pattern to optical aberrations. We present here an adaptive optics-based correction method that compensates for these aberrations and allows STED-FCS measurements in the cytoplasm of living cells.

description: We propose an assistive technology that helps individuals with Color Vision Deficiencies (CVD) to recognize/name colors. A dichromat's color perception is a reduced two-dimensional (2D) subset of a normal trichromat's three dimensional color (3D) perception, leading to confusion when visual stimuli that appear identical to the dichromat are referred to by different color names. Using our proposed system, CVD individuals can interactively induce distinct perceptual changes to originally confusing colors via a computational color space transformation. By combining their original 2D precepts for colors with the discriminative changes, a three dimensional color space is reconstructed, where the dichromat can learn to resolve color name confusions and accurately recognize colors. Our system is implemented as an Augmented Reality (AR) interface on smartphones, where users interactively control the rotation through swipe gestures and observe the induced color shifts in the camera view or in a displayed image. Through psychophysical experiments and a longitudinal user study, we demonstrate that such rotational color shifts have discriminative power (initially confusing colors become distinct under rotation) and exhibit structured perceptual shifts dichromats can learn with modest training. The AR App is also evaluated in two real-world scenarios (building with lego blocks and interpreting artistic works); users all report positive experience in using the App to recognize object colors that they otherwise could not.

description: The adhesion of fibrillar dry adhesives, mimicking nature's principles of contact splitting, is commonly characterized by using axisymmetric probes having either a flat punch or spherical geometry. When using spherical probes, the adhesive pull-off force measured depends strongly on the compressive preload applied when making contact and on the geometry of the probe. Together, these effects complicate comparisons of the adhesive performance of micropatterned surfaces measured in different experiments. In this work we explore these issues, extending previous theoretical treatments of this problem by considering a fully compliant backing layer with an array of discrete elastic fibrils on its surface. We compare the results of the semi-analytical model presented to existing continuum theories, particularly with respect to determining a measurement system- and procedure-independent metric for the local adhesive strength of the fibrils from the global pull-off force. It is found that the discrete nature of the interface plays a dominant role across a broad range of relevant system parameters. Accordingly, a convenient tool for simulation of a discrete array is provided. An experimental procedure is recommended for use in conjunction with this tool in order to extract a value for the local adhesive strength of the fibrils, which is independent of the other system properties (probe radius, backing layer thickness, and preload) and thus is suitable for comparison across experimental studies.

description: Charm baryon decay plays an important role in studying non-perturbative baryonic transitions. Compared to other hadron multiplets, the flavor symmetry of baryon decuplet is more simple and attractive. In this work, we study the topological amplitudes of charmed baryon decays into decuplet baryon in the flavor symmetry and the linear $SU(3)_F$ breaking. It is found most of topological diagrams are suppressed by the Körner-Pati-Woo theorem in the $SU(3)_F$ limit. Only two independent amplitudes contributing to the $\mathcal{B}_{c\overline 3}\to \mathcal{B}_{10}M$ decays, with one dominating the branching fractions. The Lee-Yang parameters of all $\mathcal{B}_{c\overline 3}\to \mathcal{B}_{10}M$ modes are the same in the $SU(3)_F$ limit, and there are only four possible values for the CP asymmetries. After including the first-order $SU(3)_F$ breaking effects, the $Ξ^+_c\to Σ^{* +}\overline K^0$ and $Ξ^+_c\to Ξ^{* 0}π^+$ decays have non-zero branching fractions. The number of free parameter contributing to the $\mathcal{B}_{c\overline 3}\to \mathcal{B}_{10}M$ decays in the linear $SU(3)_F$ breaking is smaller than the available data. The $SU(3)_F$ breaking part of the quark loop diagram can be extracted by global fitting of branching fractions, which could help us understand the CP violation in charm sector. Additionally, some new isospin equations are proposed to test the Körner-Pati-Woo theorem.

description: Living cells provide a fluctuating, out-of-equilibrium environment in which genes must coordinate cellular function. DNA looping, which is a common means of regulating transcription, is very much a stochastic process; the loops arise from the thermal motion of the DNA and other fluctuations of the cellular environment. We present single-molecule measurements of DNA loop formation and breakdown when an artificial fluctuating force, applied to mimic a fluctuating cellular environment, is imposed on the DNA. We show that loop formation is greatly enhanced in the presence of noise of only a fraction of $k_B T$, yet find that hypothetical regulatory schemes that employ mechanical tension in the DNA--as a sensitive switch to control transcription--can be surprisingly robust due to a fortuitous cancellation of noise effects.

description: Scaphoxium shavrini sp. nov. ( Figs 13–15) Holotype ♂ MHNG: Mindanao, Araibo, Pantukan, Compostela Valley, 900 m, Candalaga / Mts., 7°16’35.3’’N, 126°10’12.8’’E, 4.5.2019 Shavrin A.V. leg. Derivatio nominis: Patronymic. The species is dedicated to its collector Alexei V. Shavrin (Daugavpils, Latvia), a well-known expert of rove beetles. Description: Length 1.54 mm, width 0.77 mm, dorsoventral diameter 0.86 mm. Head and most of body evenly very dark reddish-brown, apical abdominal segments, femora and tibiae lighter, tarsi lighter than tibiae, antennae brown. Length/ width rations of antennomeres as: III 20 /6: IV 19 /6: V 26 /6: VI 22 /7: VII 39 /11: VIII 25/11: IX 38 /13: X 33 /13: XI 48 /15. Pronotal punctation very fine, hardly visible at 50 times magnification. Scutellum concealed. Elytral punctation distinct, fine and dense, sutural striae starting about 0.20 mm posterior of level of pronotal lobe. Mesoventrite not striate, impressed and with low mesal ridge narrowed apically. Median part of metaventrite slightly convex, with irregular transverse row of extremely fine punctures. Lateral parts of metaventrite appearing impunctate near metacoxae, each with dense patch of conspicuously coarse punctures and oblique ridge. Mesocoxal areas about 0.05 mm, almost as halves of shortest intervals to metacoxae. Metanepisterna slightly convex, about 0.06 mm wide, with curved, deep, apically shortened sutures. Ventrite I with few distinct basal punctures, not microsculptured. Following ventrites and exposed tergites with punctulate microsculpture and extremely fine punctation. Male segments I to III of protarsi slightly widened. Aedeagus (Figs 13–15) 0.68 mm long. Differential diagnosis: This new species is likely related with S. alesi LÖbl, 2011. It may be distinguished by the dark body-colour, the shorter sutural striae of the elytra, the sides of the metaventrite bearing dense and coarse punctures, the shape of the angular subapical parameral lobes and the presence of strongly sclerotized denticles in the internal sac of the aedeagus.

Correlated volume-energy fluctuations of phospholipid membranes: A simulation study

description: This paper reports all-atom computer simulations of five phospholipid membranes (DMPC, DPPC, DMPG, DMPS, and DMPSH) with focus on the thermal equilibrium fluctuations of volume, energy, area, thickness, and chain order. At constant temperature and pressure, volume and energy exhibit strong correlations of their slow fluctuations (defined by averaging over 0.5 nanosecond). These quantities, on the other hand, do not correlate significantly with area, thickness, or chain order. The correlations are mainly reported for the fluid phase, but we also give some results for the ordered (gel) phase of two membranes, showing a similar picture. The cause of the observed strong correlations is identified by splitting volume and energy into contributions from tails, heads, and water, and showing that the slow volume-energy fluctuations derive from van der Waals interactions of the tail region; they are thus analogous to the similar strong correlations recently observed in computer simulations of the Lennard-Jones and other simple van der Waals type liquids [U. R. Pedersen et al., Phys. Rev. Lett. 2008, 100, 015701]. The strong correlations reported here confirm one crucial assumption of a recent theory for nerve signal propagation proposed by Heimburg and Jackson [T. Heimburg and A. D. Jackson, Proc. Natl. Acad. Sci. 2005, 102, 9790-9795].

Estimating multipartite entanglement measures

Subjects: subject: Quantum Physics (quant-ph)

description: We investigate the lower bound obtained from experimental data of a quantum state $ρ$, as proposed independently by Gühne et al. and Eisert et al. for mixed states of three qubits. The measure we consider is the convex-roof extended three-tangle. Our findings highlight an intimate relation to lower bounds obtained recently from so-called characteristic curves of a given entanglement measure. We apply the bounds to estimate the three-tangle present in recently performed experiments aimed at producing a three-qubit GHZ state. A non-vanishing lower bound is obtained if the GHZ-fidelity of the produced states is larger than 3/4.

Solutions in difluorophosphoric acid
Creators: name: Reed, William
Publisher: name: University of British Columbia
Year: 2011

description: The physical and inorganic chemistry of solutions in difluorophosphoric acid, HPO₂F₂, has been studied, as part of a general study of solutions in non-aqueous protonic solvents. Difluorophosphoric acid is a colourless, associated liquid which might be expected to have solvent properties similar to those of other protonic systems such as H₂O, H₂SO₄ and HSO₃F. However, electrical conductivity studies of solutions of various electrolytes and nuclear magnetic resonance studies of solutions of alkali metal difluorophosphates indicate that the acid is a poor solvent for electrolytes and that ion-pairing is probably extensive. Acid-base behaviour in HPO₂F₂ has been extensively investigated. Compounds which behave as bases in this system include metal difluorophosphates, chlorides, nitrates and carbonates, organic amines, and some organic nitro-compounds and carboxylic acids. Inorganic molecules such as H₂SO₄, HSO₃F and SbF₅ behave as acids. Reaction between an acid and a base in HPO₂F₂ commonly result in the formation of an insoluble salt. The reaction between KPO₂F₂ and SbF₅, for example, has been used to prepare the new compound KSbF₅PO₂F₂. To further investigate the factors affecting acid strengths, cryoscopic and electrical conductivity studies of various inorganic oxy-acids were carried out in nitrobenzene, as solvent. The acids H₂SO₄, HSO₃F and HPO₂F₂ appeared to be virtual non-electrolytes in nitrobenzene, with H₂SO₄ apparently exhibiting some polymerization.

description: Wir betrachten Spiele für zwei und mehrere Spieler auf Cayleygraphen. In den Relator Games von Gates und Kelvey verlängern zwei Spieler abwechselnd einen gemeinsamen Pfad in dem Cayleygraphen, wobei Kreise entweder angestrebt oder vermieden werden. Wir präsentieren einige Erkenntnisse über Relator Games für Coxeter-Gruppen. Weiters betrachten wir das Spiel Cops and Robbers sowie obere Schranken für die Cop-Zahl, die minimale Anzahl an Cops, die für einen bestimmten Graphen notwendig ist, um das Spiel immer zu gewinnen. Wir besprechen ein Publikation von Frankl über die Cop-Zahl von Cayleygraphen, sowie ein aktuelles Preprint von Biswas und Saha, in dem Frankls Methode auf Cayley-Summengraphen und andere algebraische Graphen angewendet wird. Für beide Arbeiten weisen wir auf kleinere Probleme in den Beweisen hin und schlagen Möglichkeiten vor, diese zu korrigieren.
description: We study two- and more-player games on Cayley graphs. In the relator games introduced by Gates and Kelvey, two players add to a joint path through the Cayley graph while seeking or avoiding cycles. We present our insights about relator games on Coxeter groups. We also consider the cops and robbers game and upper bounds on the cop number, the minimum number of cops needed to always win the game, for a given graph. We discuss a paper by Frankl on the cop number of Cayley graphs (under some assumptions on the group’s generating set), as well as a recent preprint by Biswas and Saha extending Frankl’s method to Cayley sum graphs and other algebraic graphs. In both cases, we point out minor issues in the proofs and propose corrections.
