Observational Signposts Of Brown Dwarf Formation Mechanisms
Creators: name: Dodson-Robinson, Sarah
Publisher: name: Zenodo

Subjects: brown dwarfs
stars: formation

description: The coldest known Y dwarfs have lower mass limits similar to the masses of exoplanets recently discovered by direct imaging, such as the companions to HR 8799 and beta Pictoris. Using proper motions and parallaxes inferred from new Spitzer and Keck observations, Beichman et al. (2014) inferred a mass range of 10-30 Jupiter masses for 15 late T- and Y-type field dwarfs discovered by the WISE survey. For objects in this mass range, three formation mechanisms--starlike formation, disk instability and core accretion--are theoretically possible. Here I discuss observational signposts of brown dwarf formation mechanisms, focusing specifically on masses and velocities of the objects in the Beichman et al. (2014) sample. Most of the objects are too massive to be well represented in the exoplanet population synthesis models of Mordasini et al. (2012), suggesting that core accretion is an unlikely formation mechanism. Without radial velocities, computation of the sample's true velocity distribution is not possible, but the tangential velocity distribution is not significantly different from that of field T dwarfs (Faherty et al. 2009). For the bulk of the sample, the starlike formation pathway seems most probable. However, there are two objects under 15 Jupiter masses that have tangential velocities over 70 km s-1 that may be promising candidates for planet-like formation, assuming they are not halo or thick-disk objects. Given that Pinfield et al. (2014) also noted the high velocity of the newly discovered Y-dwarf WISE J030449.03-270508.3, T- and Y-dwarf velocities may be a promising line of inquiry for future investigations of the brown dwarf-exoplanet connection.

Transverse momentum cross section of $e^+e^-$ pairs in the $Z$-boson region from $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV

description: The transverse momentum cross section of $e^+e^-$ pairs in the $Z$-boson mass region of 66-116 GeV/$c^2$ is precisely measured using Run II data corresponding to 2.1 fb$^{-1}$ of integrated luminosity recorded by the Collider Detector at Fermilab. The cross section is compared with quantum chromodynamic calculations. One is a fixed-order perturbative calculation at ${\cal O}(α_s^2)$, and the other combines perturbative predictions at high transverse momentum with the gluon resummation formalism at low transverse momentum. Comparisons of the measurement with calculations show reasonable agreement. The measurement is of sufficient precision to allow refinements in the understanding of the transverse momentum distribution.

description: We model magnetars as hybrid stars, which have a core of quark matter surrounded by hadronic matter. For this purpose, we use an extended version of the SU(3) non-linear realization of the sigma model in which the degrees of freedom change naturally from hadrons to quarks as the temperature/density increases. The presence of a variable magnetic field allows us to study in detail the influence of Landau quantization and the anomalous magnetic moment on the particle population of the star, more precisely on particles with different spin projections. This allows us to calculate the polarization of the system throughout different phases of the star, hadronic, quark and also a mixed phase.

Subjects: subject: Systems and Control (eess.SY)

description: This paper presents a new control, namely additive-state-decomposition dynamic inversion stabilized control, that is used to stabilize a class of multi-input multi-output (MIMO) systems subject to nonparametric time-varying uncertainties with respect to both state and input. By additive state decomposition and a new definition of output, the considered uncertain system is transformed into a minimum-phase uncertainty-free system with relative degree one, in which all uncertainties are lumped into a new disturbance at the output. Subsequently, dynamic inversion control is applied to reject the lumped disturbance. Performance analysis of the resulting closed-loop dynamics shows that the stability can be ensured. Finally, to demonstrate its effectiveness, the proposed control is applied to two existing problems by numerical simulation. Furthermore, in order to show its practicability, the proposed control is also performed on a real quadrotor to stabilize its attitude when its inertia moment matrix is subject to a large uncertainty.

description: In the framework of gauge mediation models, we investigate scenarios with heavy squarks and light sleptons, motivated by the recent discovery of the Higgs boson and the deviation of the muon anomalous magnetic moment (g-2) from the SM prediction. We show that only models with a messenger multiplet in the adjoint representation of SU(5) GUT gauge group are the unique possibility that sleptons are light enough to explain the muon g-2 in the minimal setup. We also show that, if there is an additional source of the Higgs soft masses, the muon g-2 can be explained with messenger multiples in the fundamental representation of SU(5) with the help of the light higgsino. Some phenomenological aspects of these models are also discussed.

Full magnetoelectric response of Cr2O3 from first principles

description: The linear magnetoelectric response of Cr2O3 at zero temperature is calculated from first principles by tracking the change in magnetization under a macroscopic electric field. Both the spin and the orbital contributions to the induced magnetization are computed, and in each case the response is decomposed into lattice and electronic parts. We find that the transverse response is dominated by the spin-lattice and spin-electronic contributions, whose calculated values are consistent with static and optical magnetoelectric measurements. In the case of the longitudinal response, orbital contributions dominate over spin contributions, but the net calculated longitudinal response remains much smaller than the experimentally measured one at low temperatures. We also discuss the absolute sign of the magnetoelectric coupling in the two time-reversed magnetic domains of Cr2O3.

Multiscale Gyrokinetics for Rotating Tokamak Plasmas II: Reduced Models for Electron Dynamics

description: In this paper, we extend the multiscale approach developed in [Abel et. al., Rep. Prog. Phys., submitted] by exploiting the scale separation between ions and the electrons. The gyrokinetic equation is expanded in powers of the electron to ion mass ratio, which provides a rigorous method for deriving the reduced electron model. We prove that ion-scale electromagnetic turbulence cannot change the magnetic topology, and argue that to lowest order the magnetic field lies on fluctuating flux surfaces. These flux surfaces are used to construct magnetic coordinates, and in these coordinates a closed system of equations for the electron response to ion-scale turbulence is derived. All fast electron timescales have been eliminated from these equations. We also use these magnetic surfaces to construct transport equations for electrons and for electron heat in terms of the reduced electron model.

Magnetic Quantum Phase Diagram of Magnetic Impurities in 2 Dimensional Disordered Electron Systems

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The quantum phase diagram of disordered electron systems as function of the concentration of magnetic impurities nm and the local exchange coupling J is studied in the dilute limit. We take into account the Anderson localisation of the electrons by a nonperturbative numerical treatment of the disorder potential. The competition between RKKY interaction JRKKY and the Kondo effect, as governed by the temperature scale TK, is known to gives rise to a rich magnetic quantum phase diagram, the Doniach diagram. Our numerical calculations show that in a disordered system both the Kondo temperature TK and JRKKY are widely distributed. Accordingly, also their ratio, JRKKY /TK is widely distributed as shown in Fig. 1 (a). However, we find a sharp cutoff of that distribution, which allows us to define a critical density of magnetic impurities nc below which Kondo screening wins at all sites of the system above a critical coupling Jc, forming the Kondo phase[see Fig. 1 (b)]. As disorder is increased, Jc increases and a spin coupled phase is found to grow at the expense of the Kondo phase. From these distribution functions we derive the magnetic susceptibility which show anomalous power law behavior. In the Kondo phase that power is determined by the wide distribution of the Kondo temperature, while in the spin coupled phase it is governed by the distribution of JRKKY. At low densities and small J < Jc we identify a paramagnetic phase. We also report results on a honeycomb lattice, graphene, where we find that the spin coupled phase is more stable against Kondo screening, but is more easily destroyed by disorder into a PM phase.
Fine-Wilf Graphs and the Generalized Fine-Wilf Theorem
Creators: name: Rankin, Stuart A.
Publisher: name: Zenodo
Year: 2013

description: The Fine-Wilf theorem was generalized to finite sequences with three periods by M. G. Castelli, F. Mignosi, and A. Restivo. They introduced a function f from the set of all ordered triples of nonnegative integers to the set of positive integers which was critical to their analysis, and they introduced the graphs that we shall refer to as Fine-Wilf graphs. The work of Castelli et al. was generalized by R. Tijdeman and L. Zamboni, who introduced a function fw from the set of all sequences of nonnegative integers to the set of positive integers that was essential to their analysis. In this paper, we obtain an alternative formulation of f and fw, and we use this formulation to establish important properties of f and fw, obtaining in particular new upper and lower bounds for each. We also carry out an investigation of Fine-Wilf graphs for arbitrary finite sequences, showing how they are related to f and fw.

description: Abstract

This paper combines insights from the New Economics of Labour Migration and Sen’s capability approach to analyse how financial constraints and social policy in the sending country influence migration decisions of households. It particularly looks into social protection (cash transfers) and quasi-public goods (health and education infrastructure) in Indonesia. The paper analyses the impact of the 2005 unconditional cash transfers scheme in Indonesia on households’ migration decisions. It combines internal and international migration in an integrated empirical analysis. Household-level data from the Indonesian Family Life Survey and the district-level data of education and health infrastructure are used for the empirical analysis.

This paper finds that financial constraints and social policy significantly impact migration decisions. Their effects, however, vary according to the households’ deprivation profiles and the types of migration. The impact of unconditional cash transfer schemes depends on its income and substitution effects. Using propensity score matching strategy, I find that unconditional cash transfers increase the incentives for households to engage in internal migration but have no significant impact on international migration. I also find that multidimensionally poor households who receive unconditional cash transfers are less likely to have an international migrant family member but are more likely to engage in internal migration. Households with lack access to finance have lower propensity to participate in international migration. Better access to education and health facilities is associated with less international migration.

description: Prophylactic human papillomavirus (HPV) vaccines have been licensed for over ten years. They were initially administered as a three-dose regimen over a six-month period. In 2014, following a review of the evidence for dose reduction by the World Health Organization (WHO) Strategic Advisory Group of Experts (SAGE) on Immunization, a two-dose regimen for individuals aged younger than 15 years was recommended. Since that time, evidence from observational studies suggests that a single-dose HPV vaccine may also provide protection against HPVinfectionand its sequelae. The primary objective of this paperis to summarize and assess the current evidence fora single-dose HPV vaccination schedule. We also identify gaps that remain in determining whether a single dose could be sufficiently protective to have a major impact against HPV infection and its sequelae within the context of immunization programs.The evidence has been compiled by a working group of the Single-Dose HPV Vaccine Evaluation Consortium, whose members representtechnical depth, a wide global reach, and extensive expertise in immunization programs, HPV vaccine introductions, and vaccine policy. Coordinated by PATH, the Consortium includes the London School of Hygiene & Tropical Medicine, the US Centers for Disease Control and Prevention, Harvard University, the US National Cancer Institute, Université Laval, the University of British Columbia, and the Wits Reproductive Health and HIV Institute at the University of Witwatersrand. The Consortium leverages the experience of expert groups working in HPV vaccine and other vaccine introductions. Members represent groups that have actively generated evidence for HPV vaccine safety and efficacy,as well as post-licensure effectiveness and delivery.They have implemented HPV vaccine delivery programs in numerous countries, comprehensively evaluated the delivery and impact of HPV vaccines

description: Abstract

This paper presents a conceptual framework to examine how the state shapes international migration in origin and destination countries, particularly in former colonies transitioning to independence or non-sovereignty. This paper proposes an expanded view of the state’s relevance in migration and introduces a conceptualisation of a country’s transition from colonial status to independence or non-sovereignty. This is done by presenting four hypothetical scenarios of the different ways in which migration patterns shift in reaction to the introduction and timing of independence and border regimes.

description: The key to fully leveraging the potential of the electrochemical CO₂ reduction reaction (CO2RR) to achieve a sustainable solar-power-based economy is the developmentof high-performance electrocatalysts. The development process relies heavily on trial and error methods due to poormechanistic understanding of the reaction. Demonstrated here is that ionic liquids (ILs) can be employed as achemical trapping agent to probe CO2RR mechanistic pathways. This method is implemented by introducing a small amount of an IL([BMIm][NTf₂]) to a copper foam catalyst, on which a wide range of CO2RR products,including formate, CO, alcohols, and hydrocarbons, can be produced. The IL can selectively suppress the formation of ethylene, ethanol and n-propanol while having little impact on others. Thus, reaction networks leading to various products can be disentangled. The results shed new light on the mechanistic understanding of the CO2RR, and provide guidelines for modulating the CO2RR properties. Chemical trapping using an IL adds to the toolbox to deduce the mechanistic understanding of electrocatalysis and could be applied to other reactions as well.

description: The usual (type A) thin-wall Coleman-de Luccia instanton is made by a bigger-than-half sphere of the false vacuum and a smaller-than-half sphere of the true vacuum. It has a the standard O(4) symmetric negative mode associated with changing the size of false vacuum region. On the other hand, the type B instanton, made by two smaller-than-half spheres, was believed to have lost this negative mode. We argue that such belief is misguided due to an over-restriction on Euclidean path integral. We introduce the idea of a "purely geometric junction" to visualize why such restriction could be removed, and then explicitly construct this negative mode. We also show that type B and type A instantons have the same thermal interpretation for mediating tunnelings.

description: We study the surface plasmon (SP) resonance energy of isolated spherical Ag nanoparticles dispersed on a silicon nitride substrate in the diameter range 3.5-26 nm with monochromated electron energy-loss spectroscopy. A significant blueshift of the SP resonance energy of 0.5 eV is measured when the particle size decreases from 26 down to 3.5 nm. We interpret the observed blueshift using three models for a metallic sphere embedded in homogeneous background material: a classical Drude model with a homogeneous electron density profile in the metal, a semiclassical model corrected for an inhomogeneous electron density associated with quantum confinement, and a semiclassical nonlocal hydrodynamic description of the electron density. We find that the latter two models provide a qualitative explanation for the observed blueshift, but the theoretical predictions show smaller blueshifts than observed experimentally.in a homogeneous medium.

description: The IceCube Collaboration recently reported a stringent upper limit on the high energy neutrino flux from GRBs, which provides a meaningful constraint on the standard internal shock model. Recent broad band electromagnetic observations of GRBs also challenge the internal shock paradigm for GRBs, and some competing models for gamma-ray prompt emission have been proposed. We describe a general scheme for calculating the GRB neutrino flux, and compare the predicted neutrino flux levels for different models. We point out that the current neutrino flux upper limit starts to constrain the standard internal shock model. The dissipative photosphere models are also challenged if the cosmic ray luminosity from GRBs is at least 10 times larger than the gamma-ray luminosity. If the neutrino flux upper limit continues to go down in the next few years, then it would suggest the following possibilities: 1. the photon-to-proton luminosity ratio in GRBs is anomalously high for shocks, which may be achieved in some dissipative photosphere models and magnetic dissipation models; or 2. the GRB emission site is at a larger radius than the internal shock radius, as expected in some magnetic dissipation models such as the ICMART model.

description: To address the uniqueness issues associated with the Dirichlet problem for the $N$-harmonic equation on the unit disk $\D$ in the plane, we investigate the $L^p$ integrability of $N$-harmonic functions with respect to the standard weights $(1-|z|^2)^α$. The question at hand is the following. If $u$ solves $Δ^N u=0$ in $\D$, where $Δ$ stands for the Laplacian, and [\int_\D|u(z)|^p (1-|z|^2)^α\diff A(z)β(N,p)$ there exist non-trivial functions $u$ with $Δ^N u=0$ of the given integrability, while for $α\leβ(N,p)$, only $u(z)\equiv0$ is possible. We also investigate the obstruction to uniqueness for the Dirichlet problem, that is, we study the structure of the functions in $\mathrm{PH}^p_{N,α}(\D)$ when this space is nontrivial. We find a fascinating structural decomposition of the polyharmonic functions -- the cellular (Almansi) expansion -- which decomposes the polyharmonic weighted $L^p$ in a canonical fashion. Corresponding to the cellular expansion is a tiling of part of the $(p,α)$ plane into cells. A particularly interesting collection of cells form the entangled region.

description: Since the discovery of the Amonton's law and with support of modern tribological models, friction between surfaces of three-dimensional materials is known to generally increase when the surfaces are in closer contact. Here, using molecular dynamics simulations of friction force microscopy on suspended graphene, we demonstrate an increase of friction when the scanning tip is retracted away from the sample. We explain the observed behavior and address why this phenomenon has not been observed for isotropic 3-D materials.
Directed Motion of Elongated Active Polymers

description: Previous work shows that a net directed motion arises from a system of individual particles undergoing run-and-tumble dynamics in the presence of an array of asymmetric barriers. Here, we show that when the individual particle is replaced by a chain of particles linked to each other by spring forces (polymer), the rectification is enhanced. It is found that the rectification increases when the number of particles in each polymer, as well as its length, increases. In addition, the rectification increases when the size of the opening between neighboring funnel tips, lo, decreases. Interestingly, if the conformal entropic difference exceeds the thermal diffusion, net directed motion is observed even when the run-and-tumble dynamics approaches Brownian motion. Also, when the inelastic collisions between the particles and the barriers are replaced by elastic collisions, a reversed rectification is observed.

description: We extend our study of bottomonium spectral functions in the quark-gluon plasma to nonzero momentum. We use lattice QCD simulations with two flavours of light quark on highly anisotropic lattices and treat the bottom quark with nonrelativistic QCD (NRQCD). We focus on S wave (Upsilon and eta_b) channels and consider nonrelativistic velocities, v/c < 0.2. A comparison with predictions from effective field theory is made.

Effect of polydispersity, bimodality and aspect ratio on the phase behavior of colloidal platelet suspensions

Year: 2012
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We use a Fundamental-Measure density functional for hard board-like polydisperse particles, in the restricted-orientation approximation, to explain the phase behaviour of platelet colloidal suspensions studied in recent experiments. In particular, we focus our attention on the behavior of the total packing fraction of the mixture, $η$, in the region of two-phase isotropic-nematic coexistence as a function of mean aspect ratio, polydispersity and fraction of total volume $γ$ occupied by the nematic phase. In our model, platelets are polydisperse in the square section, of side length $σ$, but have constant thickness $L$ (and aspect ratio $κ\equiv L/<1$, with $$ the mean side length). Good agreement between our theory and recent experiments is obtained by mapping the real system onto an effective one, with excluded volume interactions but with thicker particles (due to the presence of long-ranged repulsive interactions between platelets). The effect of polydispersity in both shape and particle size has been taken into account by using a size distribution function with an effective mean-square deviation that depends on both polydispersities. We also show that the bimodality of the size distribution function is required to correctly describe the huge two-phase coexistence gap and the nonlinearity of the function $γ(η)$, two important features that these colloidal suspensions exhibit.

Topological Fermi arcs in superfluid $^3$He

description: We consider fermionic states bound on domain walls in a Weyl superfluid $^3$He-A and on interfaces between $^3$He-A and a fully gapped topological superfluid $^3$He-B. We demonstrate that in both cases fermionic spectrum contains Fermi arcs which are continuous nodal lines of energy spectrum terminating at the projections of two Weyl points to the plane of surface states in momentum space. The number of Fermi arcs is determined by the index theorem which relates bulk values of topological invariant to the number of zero energy surface states. The index theorem is consistent with an exact spectrum of Bogolubov- de Gennes equation obtained numerically meanwhile the quasiclassical approximation fails to reproduce the correct number of zero modes. Thus we demonstrate that topology describes the properties of exact spectrum beyond quasiclassical approximation.

description: How to reconcile the free flow of information on the internet and copyright protection? That is the fundamental issue underlying the preliminary questions referred to the CJEU in the GS Media case. After Svensson and BestWater, this case again offered an opportunity for the Court to clarify how hyperlinks to works protected by a copyright should be treated under the EU copyright law framework. In these previous cases, the Court had already established that the provision of a hyperlink to a website where a work protected by a copyright was freely available with the consent of the copyright holder was not an infringement of EU copyright law. In GS Media, the CJEU had to decide whether the posting of a hyperlink to such a work published on a website without the authorisation of the copyright holder was an infringement of EU copyright law, in particular of the right of communication to the public, ensured by Art. 3, para. 1, of the Directive 2001/29, of certain aspects of copyright and related rights in the information society.

description: Four functions counting the number of subsets of {1, 2, . . . , n} having particular properties are defined by Nathanson and generalized by many authors. They derive explicit formulas for all four functions. In this paper, we point out that we need to compute only one of them as the others will follow as a consequence. Moreover, our method is simpler and leads to more general results than those in the literature.

description: We construct a holographic model of spontaneous supersymmetry breaking in analogy to AdS/QCD models. Integrating out the bulk theory one obtains an entirely four dimensional effective action that encodes spontaneous supersymmetry breaking effects, coupled to external sources. Using only this four dimensional action it is possible to compute soft masses, scattering cross sections and determine the form factors of vector mesons. This construction lends itself to a more natural comparison with operator product expansions.
