description: Trapped ion Coulomb crystals are regularly used as analogue simulators for physical systems, for which the access to the dynamics of the individual particles is lacking or which are hard to simulate using classical computers. One area of interest are solid-state friction models with two atomically flat surfaces sliding against each other. Typically, the access to the dynamics of the individual particles is lacking in realistic interfaces, therefore, ion crystals have been proposed in order to test friction models. While a model system of an ion chain sliding over a rigid optical potential has been demonstrated, a model system that implements back action between the two sliding surfaces does not exist. In this cumulative thesis, an atomic system with intrinsic back action and access to individual particles that allows the study of nanofriction is presented. The system consists of an ion Coulomb crystal in the two-dimensional zigzag phase, into which a topological defect is introduced. The defect leads to a mismatch between the ion chains, which allows for the observation of the pinning-to-sliding phase transition for a finite system. The transition shows symmetry breaking and the existence of a soft mode at zero temperature, which is a localized topological defect mode. The influence of the defect's position and type on the existence of the soft mode is studied. It is found that breaking the intrinsic symmetry of the topological defect in the sliding phase by external forces prevents the observation of the soft mode. In the presented experiments, mode frequencies are determined with resonant excitation of the collective motions of the ions via amplitude modulation of a Doppler cooling laser. A non-zero soft mode frequency at the transition is measured, which is attributed to the finite crystal temperature. Furthermore, the linear-to-zigzag transition and the zigzag mode, i.e., the soft mode of this transition, under thermal noise are investigated. An increase in the mode frequency with temperature, as well as fast switching between the two possible ground states of the two-dimensional zigzag phase is found. An analytical model is derived that explains the observed temperature dependence of the low-frequency spectrum at the linear-to-zigzag transition. This analysis has important consequences for the cooling of a soft mode near a symmetry-breaking transition. In the future, this model could be adaptable to the pinning-to-sliding transition in order to further the understanding of the thermal effects of friction and heat transport.

description: We advance spin noise spectroscopy to an ultrafast tool to resolve high-frequency spin dynamics in semiconductors. The optical nondemolition experiment reveals the genuine origin of the inhomogeneous spin dephasing in n-doped GaAs wafers at densities at the metal-to-insulator transition. The measurements prove in conjunction with depth-resolved spin noise measurements that the broadening of the spin dephasing rate does not result from thermal fluctuations or spin-phonon interaction, as suggested previously, but from spatial g -factor variations. © 2010 The American Physical Society.

description: Hitherto, six P-type planets are found around five binary systems, i.e. Kepler-16 b, 34 b, 35 b, 38 b, 47 b, c, which are all Neptune or Jupiter-like planets. The stability of planets and the habitable zones are influenced by the gravitational and radiative perturbations of binary companions. In this Letter, we check the stability of an additional habitable Earth-mass planet in each system. Based on our simulations in 10 Myr, a habitable "Earth" is hardly stable in Kepler-16 while a stable "Earth" in Kepler-47 close to the boundaries of the habitable zone is possible. In contrast, Kepler-34, 35 and 38 seem to have high probabilities of being able to tolerate a stable "Earth" in their habitable zones. The affects of transit time variations are quite small due to the small mass of an undetected "Earth", except that of Kepler-16 b. With a time precision of 0.001 day(~ 88 s), an "Earth" in the corotational resonance with Kepler-16 b can be detected in 3 years, while habitable "Earths" in Kepler-34 and 38 systems can be detected in 10 years. Habitable "Earths" in Kepler-35 and 47 are not likely to be detected in 10 years under this precision.

Robustness of first-order phase transitions in one-dimensional long-range contact processes

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: It has been proposed (Phys. Rev. E {\bf 71}, 026121 (2005)) that unlike the short range contact process, a long-range counterpart may lead to the existence a discontinuous phase transition in one dimension. Aiming at exploring such link, here we investigate thoroughly a family of long-range contact processes. They are introduced through the transition rate $1+a\ell^{-σ}$, where $\ell$ is the length of inactive islands surrounding particles. In the former approach we reconsider the original model (called $σ-$contact process), by considering distinct mechanisms of weakening the long-range interaction toward the short-range limit. Second, we study the effect of different rules, including creation and annihilation by clusters of particles and distinct versions with infinitely many absorbing states. Our results show that all examples presenting a single absorbing state, a discontinuous transition is possible for small $σ$. On the other hand, the presence of infinite absorbing states leads to distinct scenario depending on the interactions at the frontier of inactive sites.

description: Quantum Hall samples with Corbino geometry show an enhanced hysteresis of the I-V curves near the breakdown of the Quantum Hall effect at low AC frequencies. We explain this finding within a hot-electron model by an assumed reduction of the subcritical conductivity σxx (under non-equilibrium conditions) with frequency. In this study, we present measurements of σxx as a function of the frequency on various samples. The observed drop of the subcritical σxx with frequency is of the same order as predicted and proves therefore our model. © 2005 American Institute of Physics.

description: We present a nano-scale photoelectron source, optimized towards ultrashort pulse durations and well-suited for time-resolved diffraction experiments. A tungsten tip, mounted in a suppressor-extractor electrode configuration, allows the generation of 30 keV electron pulses with an estimated pulse duration of 37 fs at the gun exit. We infer the pulse duration from particle tracking simulations, which are in excellent agreement with experimental measurements of the electron-optical properties of the source. We furthermore demonstrate femtosecond laser-triggered operation. Besides the short electron pulse duration, a tip-based source is expected to feature a large transverse coherence as well as a nanometric emittance.

description: We have devised an all-optical setup for the generation of two phase-locked laser fields with a frequency difference of 3 GHz using only standard optics and two acousto-optical frequency shifters, that are operated at 253 MHz in sixtupel pass. The spectral width of the beat frequency is measured to be 300 Hz (full width at half maximum) limited by the resolution bandwidth of the spectrum analyzer. We routinely obtain an overall efficiency of more than 15% and demonstrate that the frequency shifted light can be further amplified by injecting it into additional "slave" lasers. This setup provides a low-cost alternative over conventional methods to generate laser fields with difference frequencies in the GHz domain, as for example, used in laser spectroscopy, laser cooling and trapping, and coherent manipulation of atomic quantum states. © 2000 American Institute of Physics.

description: Abstract
This study aims to analyze the executive strength of fiduciary guarantees in guarantee and banking law. The research method used is normative juridical. The results show that the execution of civil law is carried out through a court institution either because a judge's decision has permanent legal force or other documents that have executive power that can be executed through the fiat chairman of the district court such as the fiduciary guarantee certificate. The executorial title contained in the fiduciary guarantee certificate which reads "For Justice Based on Almighty Godhead" is a statement containing an authority that the document (text) has the power of execution (forced execution) with the help of state apparatus. Due to the existence of the executorial title, the holder of the fiduciary guarantee can submit a request for execution to the court and the court will comply with the execution procedure.

description: The microstructure and mechanical properties of mechanically alloyed and spark plasma sintered AlCoFeMnNi₋ₓB (x = 0, 0.5, 1, and 5 at. %) high-entropy alloys (HEAs) have been investigated. Boron-doped HEAs were synthesized using mechanical alloying up to 50 h of milling. Synthesized powders were then consolidated at 850, 900, and 950 °C for 10 min under a uniaxial pressure of 40 MPa using spark plasma sintering (SPS). A scanning electron microscope, which was equipped with energy dispersive spectroscopy (EDS), together with an optical microscope (OM) were used to analyze the microstructural evolution. X-ray diffraction analysis was used to differentiate the phases formed in the solution. The mechanical properties of the sintered specimens were analyzed using the shear-punch test (SPT). The fracture surface of the SPT samples was studied using SEM. Thermodynamic calculations revealed that by employing this process, it is possible to produce solid solution HEAs with a duplex FCC + BCC structure. It was shown that boron-doped AlCoFeMnNi high-entropy alloys contain some unique attributes. SPS at 900 °C for a sample with boron up to 0.5 at. % leads to the formation of an alloy with the highest shear strength. A further increase in the boron content in the boron-doped HEAs exhibited a decrease in the maximum shear strength. Finally, the correlations between the microstructural and mechanical characteristics of the sintered boron-containing high-entropy alloys are discussed.

description: We predict a generic manifestation of quantum interference in many-body bosonic systems resulting in a coherent enhancement of the average return probability in Fock space. This enhancement is both robust with respect to variations of external parameters and genuinely quantum insofar as it cannot be described within mean-field approaches. As a direct manifestation of the superposition principle in Fock space, it arises when many-body equilibration due to interactions sets in. Using a semiclassical approach based on interfering paths in Fock space, we calculate the magnitude of the backscattering peak and its dependence on gauge fields that break time-reversal invariance. We confirm our predictions by comparing them to exact quantum evolution probabilities in Bose-Hubbard models, and discuss the relevance of our findings in the context of many-body thermalization.

description: A crucial aspect of 3D Monte Carlo radiative transfer is the choice of the spatial grid used to partition the dusty medium. We critically investigate the use of octree grids in Monte Carlo dust radiative transfer, with two different octree construction algorithms (regular and barycentric subdivision) and three different octree traversal algorithms (top-down, neighbour list, and the bookkeeping method). In general, regular octree grids need higher levels of subdivision compared to the barycentric grids for a fixed maximum cell mass threshold criterion. The total number of grid cells, however, depends on the geometry of the model. Surprisingly, regular octree grid simulations turn out to be 10 to 20% more efficient in run time than the barycentric grid simulations, even for those cases where the latter contain fewer grid cells than the former. Furthermore, we find that storing neighbour lists for each cell in an octree, ordered according to decreasing overlap area, is worth the additional memory and implementation overhead: using neighbour lists can cut down the grid traversal by 20% compared to the traditional top-down method. In conclusion, the combination of a regular node subdivision and the neighbour list method results in the most efficient octree structure for Monte Carlo radiative transfer simulations.

description: By considering the master equation of the totally asymmetric exclusion process on a one-dimensional lattice and using two types of boundary conditions (i.e. interactions), two new families of the multi-species reaction-diffusion processes, with particle-dependent hopping rates, are investigated. In these models (i.e. reaction-diffusion and drop-push systems), we have the case of distinct particles where each particle $A_α$ has its own intrinsic hopping rate $v_α$. They also contain the parameters that control the annihilation-diffusion rates (including pair-annihilation and coagulation to the right and left). We obtain two distinct new models. It is shown that these models are exactly solvable in the sense of the Bethe anstaz. The two-particle conditional probabilities and the large-time behavior of such systems are also calculated.

description: A quantitative interpretation of the observed relation between the interstellar linear polarization curve parameters $K$ and $λ_{\max}$ characterizing the width and the wavelength of a polarization maximum, respectively, is given. The observational data available for 57 stars located in the dark clouds in Taurus, Chamaeleon, around the stars $ρ$ Oph and R CrA are considered. The spheroidal particle model of interstellar dust grains earlier applied to simultaneously interpret the interstellar extinction and polarization curves in a wide spectral range is utilized. The observed trend $K \approx 1.7 λ_{\max}$ is shown to be most likely related to a growth of dust grains due to coagulation rather than mantle accretion. The relation of the parameters $K$ and $λ_{\max}$ with an average size of silicate dust grains is discussed.

description: Abstract
This study aims to analyze the certification and guarantee of land rights over abandoned land management rights in credit applications. The research method used is normative juridical. The results show that the many banks often use debt collector services because of the high costs that must be incurred when banks want to choose the civil law route. The high cost of compensation in court is compared to the total arrears of customers, making banks prefer to use debt collector services in debt collection. With debt collector services, banks do not need to spend large costs to force debtors to pay their debts. This legal position and arrangement has the implication that debt collectors have liability obligations to two parties. Debt collectors must be responsible to the bank as a recruiter, then indirectly must also be responsible to Bank Indonesia because various debt collector obligations must be fulfilled later will be reported by the bank to Bank Indonesia. The results of this study conclude that the bank is responsible for everything done by the debt collector in collecting to customers and the debt collector has responsibility to two parties, namely to the recruiting bank and the customer.

description: FAMILY STELLIGERIDAE LENDENFELD, 1898
Emended diagnosis: Axinellida in which the choanaosomal skeleton can be composed of styles, tylostyles, oxeas or rhabdostyles. Ectosomal region often with protruding megascleres surrounded by bouquets of smaller, slender accessory oxeas or styles. Ectosomal crust heavily reinforced with microscleres. Accessory oxeas often with centrotylote swellings, occasionally with fissurate terminations. Microscleres can be smooth-rayed euasters; spined microxeas often bent or centrangulate or acanthose cladotoxas and birotules. Where known, reproduction is oviparous. Presence of cells with granular inclusions in most species. All produce slime on collection.

Type genus: Stelligera Gray, 1867.
Remarks: A detailed description of the morphological characters that unite Stelligeridae is given in the Discussion. The molecular trees of Lim et al. (2017) clearly show that Plenaster is not a stelligerid; the taxonomic affinities of this genus will be part of a future manuscript.

description: An Atomic Force Microscope is used to locally manipulate a single layer graphene sheet. Transport measurements in this region as well as in the unmanipulated part reveal different charge carrier densities while mobilities stay in the order of 10000 cm^2/(Vs). With a global backgate, the system is tuned from a unipolar n-n' or p-p' junction with different densities to a bipolar p-n junction. Magnetotransport across this junction verifies its nature, showing the expected quantized resistance values as well as the switching with the polarity of the magnetic field. The mixing of edge states at the p-n junction is shown to be supressed at high magnetic fields.

Adapting sample size in particle filters through KLD-resampling

description: This letter provides an adaptive resampling method. It determines the number of particles to resample so that the Kullback-Leibler distance (KLD) between distribution of particles before resampling and after resampling does not exceed a pre-specified error bound. The basis of the method is the same as Fox's KLD-sampling but implemented differently. The KLD-sampling assumes that samples are coming from the true posterior distribution and ignores any mismatch between the true and the proposal distribution. In contrast, we incorporate the KLD measure into the resampling in which the distribution of interest is just the posterior distribution. That is to say, for sample size adjustment, it is more theoretically rigorous and practically flexible to measure the fit of the distribution represented by weighted particles based on KLD during resampling than in sampling. Simulations of target tracking demonstrate the efficiency of our method.

description: The attractive branch of the interaction potentials with the surface of gold have been computed for a large variety of atomic systems: the hydrogen atom, noble gases (He, Ne, Ar, Kr, Xe), alkali atoms (Li, Na, K, Rb, Cs) and alkaline atoms (Be, Mg, Ca, Sr, Ba). The results include highly accurate dynamic polarizabilities for the helium atom calculated using a variational method and explicitly correlated wavefunctions. For other atoms considered we used the data available in the literature. The interaction potentials include both the effects of retardation of the electromagnetic interactions and a realistic representation of the optical response function of gold (beyond the approximation of a perfect conductor). An explicit comparison of our result to the interaction between an atom and a perfect conductor is given.

The proposed method may be used to support the feasibility of a given statement by testing it against a relevant system model. To achieve this, a novel method for modeling the system and evidential statements is given. The method is then examined in a case study example.

description: A one-dimensional boundary layer model was used to study the effects of uncertain input data on 2-m temperature and 10-m wind. Based on a very large number of numerical results, it can be demonstrated, that even a small degree of ambiguity can have significant implications, especially for temperature. In 50 % of all 6,000 simulations for flat terrain and randomly chosen sets of input data within narrow limits, temperature uncertainty was more than 2 K, and in 14 % of all cases more than 4 K, with a maximum of 9 K. Effect on wind speed is much smaller and depends mostly on surface roughness length. For a forest scenario, the results for temperature of 18,000 simulations are in the same order, with 25 % of the ensemble show temperature uncertainties of more than 2 K, and 6 % of more than 4 K, while wind speed above a forest is much more affected than for the bare soil case. In addition, the contribution of uncertainties of individual input data was estimated.

description: Anhand von Fünf Interviews von Regisseur:innen aus dem Film und Theaterbereich gehe ich der Frage nach, wie viel Einfluss verschiedene Methodiken aus dem Schauspiel und der Dramaturgie auf die jeweilige Arbeit des Regisseurs am Schauspieler haben. Dabei kommen unter anderem Meinungen über Brecht, Stanislawski und die Biomechanik vor. Die Interviews sind ineinander vermischt, dass es sich fast wie eine Diskussionsrunde liest. Die Regisseur:innen legen dazu verschiedenste Meinungen und Arbeitsweisen dar und finden doch immer wieder einen Konsens. Es wurden dabei keine scharfen Grenzen gezogen, dass auch über die Methodik hinaus Themen zur Schauspielführung besprochen werden.

Distance to the scaling law: a useful approach for unveiling relationships between crime and urban metrics

description: We report on a quantitative analysis of relationships between the number of homicides, population size and other ten urban metrics. By using data from Brazilian cities, we show that well defined average scaling laws with the population size emerge when investigating the relations between population and number of homicides as well as population and urban metrics. We also show that the fluctuations around the scaling laws are log-normally distributed, which enabled us to model these scaling laws by a stochastic-like equation driven by a multiplicative and log-normally distributed noise. Because of the scaling laws, we argue that it is better to employ logarithms in order to describe the number of homicides in function of the urban metrics via regression analysis. In addition to the regression analysis, we propose an approach to correlate crime and urban metrics via the evaluation of the distance between the actual value of the number of homicides (as well as the value of the urban metrics) and the value that is expected by the scaling law with the population size. This approach have proved to be robust and useful for unveiling relationships/behaviors that were not properly carried out by the regression analysis, such as i) the non-explanatory potential of the elderly population when the number of homicides is much above or much below the scaling law, ii) the fact that unemployment has explanatory potential only when the number of homicides is considerably larger than the expected by the power law, and iii) a gender difference in number of homicides, where cities with female population below the scaling law are characterized by a number of homicides above the power law.

description: A leading model for Type Ia supernovae (SNe Ia) begins with a white dwarf near the Chandrasekhar mass that ignites a degenerate thermonuclear runaway close to its center and explodes. In a series of papers, we shall explore the consequences of ignition at several locations within such dwarfs. Here we assume central ignition, which has been explored before, however, the problem is worth revisiting, if only to validate those previous studies and to further elucidate the relevant physics for future work. A perturbed sphere of hot iron ash with a radius of ~100 km is initialized at the middle of the star. The subsequent explosion is followed in several simulations using a thickened flame model in which the flame speed is either fixed --- within the range expected from turbulent combustion --- or based on the local turbulent intensity. Global results, including the explosion energy and bulk nucleosynthesis (e.g. 56Ni of 0.48--0.56 $\Msun$) turn out to be insensitive to this speed. In all completed runs, the energy released by the nuclear burning is adequate to unbind the star, but not enough to give the energy and brightness of typical SNe Ia. As found previously, the chemical stratification observed in typical events is not reproduced. These models produce a large amount of unburned carbon and oxygen in central low velocity regions, which is inconsistent with spectroscopic observations, and the intermediate mass elements and iron group elements are strongly mixed during the explosion.
