Lessons from cosmic history: The case for a linear star formation -- H2 relation
Creators: name: Feldmann, R.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: Observations show that star formation in galaxies is closely correlated with the abundance of molecular hydrogen. Modeling this empirical relation from first principles proves challenging, however, and many questions regarding its properties remain open. For instance, the exact functional form of the relation is still debated and it is also unknown whether it applies at z>4, where CO observations are sparse. Here, we analyze how the shape of the star formation -- gas relation affects the cosmic star formation history and global galaxy properties using an analytic model that follows the average evolution of galaxies in dark matter halos across cosmic time. We show that a linear relation with an H2 depletion time of ~2.5 Gyr, as found in studies of nearby galaxies, results in good agreement with current observations of galaxies at both low and high redshift. These observations include the evolution of the cosmic star formation rate density, the z~4-9 UV luminosity function, the evolution of the mass -- metallicity relation, the relation between stellar and halo mass, and the gas-to-stellar mass ratios of galaxies. In contrast, the short depletion times that result from adopting a highly super-linear star formation -- gas relation lead to large star formation rates, substantial metal enrichment (~0.1 solar), and low gas-to-stellar mass ratios already at z~10, in disagreement with observations. These results can be understood in terms of an equilibrium picture of galaxy evolution in which gas inflows, outflows, and star formation drive the metallicities and gas fractions toward equilibrium values that are determined by the ratio of the accretion time to the gas depletion time. In this picture, the cosmic modulation of the accretion rate is the primary process that drives the evolution of stellar masses, gas masses, and metallicities of galaxies from high redshift until today.

Quantum Spin Hall Effect in a Three-orbital Tight-binding Hamiltonian

description: We consider the quantum spin hall state in a three orbital model due to certain loop current order induced by spin-dependent interactions. This type of order is motivated by the loop current model which is proposed to describe the pseudogap phase of cuprates. It is shown that this model has nontrivial Chern parity by directly counting the zeros of the Pfaffian of time reversal operator. By connecting to the second order Chern number, we explicitly show the singularities of wave-functions and how they depend on gauge choices. In this case, it is shown that the Berry phase can be mapped to Nonabelian instanton.

description: This paper is concerned with the effect of overlay network topology on the performance of live streaming peer-to-peer systems. The paper focuses on the evaluation of topologies which are aware of the delays experienced between different peers on the network. Metrics are defined which assess the topologies in terms of delay, bandwidth usage and resilience to peer drop-out. Several topology creation algorithms are tested and the metrics are measured in a simple simulation testbed. This gives an assessment of the type of gains which might be expected from locality awareness in peer-to-peer networks.

description: A skyrmion in a nanosized disk of a chiral magnet can be used as a bit of information. To this end, it is desirable to control the creation and removal of a skyrmion only by currents without using external magnetic fields. Here we propose to create a skyrmion by applying a current pulse to a nanodisk. The skyrmion can be removed from the disk by applying a dc current. We show that the dynamics of the created skyrmion can lead to a rectification effect, in which a dc voltage is generated by the motion of skyrmion in the presence of an ac current.

Topologically protected mid-gap states induced by impurity in one-dimensional superlattices

description: Based on the discovery of the nontrivial topology of one-dimensional superlattices, we show that midgap states will emerge in such systems induced by a single on-site impurity. Besides the trivial bound state located at the impurity site, these midgap states are localized at the adjacent sides of the impurity, carrying the information of the topology and behaving like the effect of the open boundary conditions in the limit of a large attractive or repulsive impurity potential. Using this feature, the impurity can be used to detect the topology of the superlattice system and to realize the adiabatic pumping between the opposite sides of the impurity in cold-atom experiments or in photonic crystals.

description: We propose a scheme to generate GHZ state of nitrogen-vacancy centers coupled to a whispering-gallery mode cavity. The implemented evolution is independent on the cavity field state with the assistant of a strong classical field, and thus not sensitive to the thermal state of the cavity. Meanwhile, it is fast compare to the convectional dispersive interaction induced operation in a cavity-assisted system. The scheme is readily scalable to multiqubit scenario.

description: To better understand the radio signal emitted by extensive air-showers and to further develop the radio detection technique of high-energy cosmic rays, the LOPES experiment was reconfigured to LOPES-3D. LOPES-3D is able to measure all three vectorial components of the electric field of radio emission from cosmic ray air showers. The additional measurement of the vertical component ought to increase the reconstruction accuracy of primary cosmic ray parameters like direction and energy, provides an improved sensitivity to inclined showers, and will help to validate simulation of the emission mechanisms in the atmosphere. LOPES-3D will evaluate the feasibility of vectorial measurements for large scale applications. In order to measure all three electric field components directly, a tailor-made antenna type (tripoles) was deployed. The change of the antenna type necessitated new pre-amplifiers and an overall recalibration. The reconfiguration and the recalibration procedure are presented and the operationality of LOPES-3D is demonstrated.

description: The weak cosmic censorship conjecture asserts that spacetime singularities that arise in gravitational collapse are always hidden inside of black holes, invisible to distant observers. This conjecture, put forward by Penrose more than four decades ago, is widely believed to be one of the basic principles of nature. However, a complete proof of this hypothesis is still lacking and the validity of the conjecture has therefore remained one of the most important open questions in general relativity. In this study we analyze a gedanken experiment which is designed to challenge cosmic censorship by trying to overcharge a Reissner-Nordström black hole: a charged shell is lowered {\it adiabatically} into the charged black hole. The mass-energy delivered to the black hole can be red-shifted by letting the dropping point of the shell approach the black-hole horizon. On the other hand, the electric charge of the shell is not red-shifted by the gravitational field of the black hole. It therefore seems, at first sight, that the charged shell is not hindered from entering the black hole, overcharging it and removing its horizon. However, in the present study we prove that the exposure of a naked singularity to distant observers is actually excluded due to the formation of a new (and {\it larger}) horizon around the original black hole. Moreover, we shall prove that this new horizon is already formed {\it before} the charged shell crosses the original black-hole horizon. This result, which seems to have been previously overlooked, guarantees the validity of the weak cosmic censorship conjecture in this type of gedanken experiments.

description: To quantify the randomness of Markov trajectories with fixed initial and final states, Ekroot and Cover proposed a closed-form expression for the entropy of trajectories of an irreducible finite state Markov chain. Numerous applications, including the study of random walks on graphs, require the computation of the entropy of Markov trajectories conditioned on a set of intermediate states. However, the expression of Ekroot and Cover does not allow for computing this quantity. In this paper, we propose a method to compute the entropy of conditional Markov trajectories through a transformation of the original Markov chain into a Markov chain that exhibits the desired conditional distribution of trajectories. Moreover, we express the entropy of Markov trajectories - a global quantity - as a linear combination of local entropies associated with the Markov chain states.

description: We present optical and near-infrared observations of SN 2012au, a slow-evolving supernova (SN) with properties that suggest a link between subsets of energetic and H-poor SNe and superluminous SNe. SN 2012au exhibited conspicuous SN Ib-like He I lines and other absorption features at velocities reaching 2 x 10^4 km/s in its early spectra, and a broad light curve that peaked at M_B = -18.1 mag. Models of these data indicate a large explosion kinetic energy of 10^{52} erg and 56Ni mass ejection of 0.3 Msolar on par with SN 1998bw. SN 2012au's spectra almost one year after explosion show a blend of persistent Fe II P-Cyg absorptions and nebular emissions originating from two distinct velocity regions. These late-time emissions include strong [Fe II], [Ca II], [O I], Mg I], and Na I lines at velocities > 4500 km/s, as well as O I and Mg I lines at noticeably smaller velocities of 2000 km/s. Many of the late-time properties of SN 2012au are similar to the slow-evolving hypernovae SN 1997dq and SN 1997ef, and the superluminous SN 2007bi. Our observations suggest that a single explosion mechanism may unify all of these events that span -21 < M_B < -17 mag. The aspherical and possibly jetted explosion was most likely initiated by the core collapse of a massive progenitor star and created substantial high-density, low-velocity Ni-rich material.

Effect of spin and yaw on boundary layer transition along a body of revolution
Creators: name: Fehrman, Alvin L
Publisher: name: California Institute of Technology
Year: 1955
Subjects: Aeronautics

description: This report covers an experimental investigation of boundary layer transition on a body of revolution at low subsonic speeds, with emphasis placed on the effects of spin and yaw on transition.

The methods tried for detecting boundary layer transition for this particular investigation are reviewed and the technique finally adopted, the use of a hot wire anemometer, is described in detail.

It was found that at angles of yaw, the transition from laminar to turbulent flow in the boundary layer occurs at a higher Reynolds number over most of the body than at zero yaw, and that spin has a negligible effect on the transition Reynolds number. It was observed however that the effect of spin varies from the front to the rear of the body, although it was not ascertained whether this effect was a result of the influence of the nose section, the tripping device which was used to obtain transition, or a combination of both.

description: The fundamental role played by black holes in many areas of physics makes it highly important to explore the nature of their stability. The stability of charged Reissner-Nordström black holes to {\it neutral} (gravitational and electromagnetic) perturbations was established almost four decades ago. However, the stability of these charged black holes under {\it charged} perturbations has remained an open question due to the complexity introduced by the well-known phenomena of superradiant scattering: A charged scalar field impinging on a charged Reissner-Nordström black hole can be {\it amplified} as it scatters off the hole. If the incident field has a non-zero rest mass, then the mass term effectively works as a mirror, preventing the energy extracted from the hole from escaping to infinity. One may suspect that the superradiant amplification of charged fields by the charged black hole may lead to an instability of the Reissner-Nordström spacetime (in as much the same way that rotating Kerr black holes are unstable under rotating scalar perturbations). However, in this Letter we show that, for charged Reissner-Nordström black holes in the regime ${(Q/M)}^2\leq 8/9$, the two conditions which are required in order to trigger a possible superradiant instability [namely: (1) the existence of a trapping potential well outside the black hole, and (2) superradiant amplification of the trapped modes] cannot be satisfied simultaneously. Our results thus support the stability of charged Reissner-Nordström black holes under charged scalar perturbations in the regime ${(Q/M)}^2\leq 8/9$.

An investigation into the effects of running propellers on the static longitudinal stability of multi-engine tractor-propeller-driven monoplanes
Creators: name: Amster, Warren
Publisher: name: California Institute of Technology
Year: 1948
Subjects: Aeronautics

description: This thesis has three main purposes:

1. To establish an engineering computation procedure for predicting C[subscript M]( c. g.) as a function of C[subscript L] and power conditions for a multi-engine monoplane of conventional configuration with tractor propellers mounted on and forward of the wing from a given curve of C[subscript M] as a function of C[subscript L] for the power-off condition.

2. To recommend aircraft configurations which will minimize destabilizing effect of power.

3. To provide a physical explanation of the effect of power on stability.

Calculated C[subscript M] vs. C[subscript L] curves are compared with "matched-power" wind tunnel model test results. The agreement is good for all-right-hand rotation of propellers but unsatisfactory for other rotation modes.

description: We study multiple helical nanowires in proximity to a common mesoscopic superconducting island, where Majorana fermion bound states are formed. We show that a weak finite charging energy of the center island may dramatically affect the low-energy behavior of the system. While for strong charging interactions, the junction decouples the connecting wires, interactions lower than a non-universal threshold may trigger the flow towards an exotic Kondo fixed point. In either case, the ideally Andreev reflecting fixed point characteristic for infinite capacitance (grounded) devices gets destabilized by interactions.

description: MOST time-series photometry of mu Eri, an SB1 eclipsing binary with a rapidly-rotating SPB primary, is reported and analyzed. The analysis yields a number of sinusoidal terms, mainly due to the intrinsic variation of the primary, and the eclipse light-curve. New radial-velocity observations are presented and used to compute parameters of a spectroscopic orbit. Frequency analysis of the radial-velocity residuals from the spectroscopic orbital solution fails to uncover periodic variations with amplitudes greater than 2 km/s. A Rossiter-McLaughlin anomaly is detected from observations covering ingress. From archival photometric indices and the revised Hipparcos parallax we derive the primary's effective temperature, surface gravity, bolometric correction, and the luminosity. An analysis of a high signal-to-noise spectrogram yields the effective temperature and surface gravity in good agreement with the photometric values. From the same spectrogram, we determine the abundance of He, C, N, O, Ne, Mg, Al, Si, P, S, Cl, and Fe. The eclipse light-curve is solved by means of EBOP. For a range of mass of the primary, a value of mean density, very nearly independent of assumed mass, is computed from the parameters of the system. Contrary to a recent report, this value is approximately equal to the mean density obtained from the star's effective temperature and luminosity. Despite limited frequency resolution of the MOST data, we were able to recover the closely-spaced SPB frequency quadruplet discovered from the ground in 2002-2004. The other two SPB terms seen from the ground were also recovered. Moreover, our analysis of the MOST data adds 15 low-amplitude SPB terms with frequencies ranging from 0.109 c/d to 2.786 c/d.

description: During the last twenty years a considerable amount of work has been done in order to understand buffeting and the mechanism of the separated flow that causes it. In these investigations the results have either not been clear or they contain some unknown interaction between the indicating apparatus and the flow in the wake. In the present paper one type of the formerly observed flow configurations is investigated by using a properly compensated hot wire anemometer. This technique exhibits some of the results previously obtained but with greater significance and some added phenomena.

description: This paper constitutes a report on one phase of an investigation sponsored by the National Advisory Committee for Aeronautics at the California Institute of Technology, namely, the determination of the allowable loads in wing nose-sections under the action of combined loading conditions. As intimated by the title, the material presented here has been limited to the case of pure torsion only, this choice being dictated by the present state of the experimental program and the interpretation of its results.

The experimental program itself consisted of the testing of specimens made up of two semi-elliptical (or semi-circular) segments of sheet supported and clamped at the ends of the minor axis of the ellipse, thus simulating two wing nose-sections mounted to a common spar and tested as a single unit.  As a result of the testing of these specimens with varying ellipticity, sheet thickness, and length, sufficient experimental data was obtained to establish rational design curves for both the buckling and ultimate failure of semi-elliptical cylinders under torsion.

Since the type of specimens used only approximated the shape of an actual wing nose-section, it was necessary to devise a means of relating the two structures, in order that the criteria presented in this paper could be used for actual design practice.

Since a limited amount of torsion tests on actual wing assemblies was available to this author, it was used to check the validity of both the geometric relation devised between the two types of structures as mentioned above and the actual design criteria developed from the experimental results. The agreement obtained was quite good, thus substantiating the usefulness and reliability of the results presented in this paper.

In the light of the above results, it is believed that the experimental portion of the investigation has been satisfactorily completed, with the possible exception of determining the affect of stiffeners upon the strength of the cylinders under discussion. However, since this represents an entirely different field of study, it is beyond the scope of this present investigation and must be relegated to the future.

Attempts were made to develop a theoretical verification of the results obtained, but due to the complexities of the problem, they met with little success for the present. Therefore, this task also remains as one to be completed as a part of any future work which may be undertaken.

At supersonic and hypersonic speeds the location of the boundary layer separation point on the surface of a smooth, blunt body is not fixed a priori, but is determined by the pressure rise communicated upstream through the subcritical base flow. By utilizing the integral or moment method of Reeves and Lees the separation-interaction region is joined smoothly to the near-wake interaction region passing through a "throat" downstream of the rear stagnation point. One interesting feature of this problem is that the viscous flow over the blunt body "overexpands" and goes supercritical. This flow is joined to the near-wake by means of a supercritical-subcritical "jump" upstream of separation, and the jump location is determined by the matching conditions.

Downstream of the jump the viscous flow separates in response to the pressure rise, and forms a constant pressure mixing region leading into the near wake. As an illustrative example the method is applied to an adiabatic circular cylinder at [...] = 6, and the results are compared with the experimental measurements of Dewey and McCarthy. This method can be extended to non-adiabatic bodies, and to slender bodies with smooth bases, provided that the radius of curvature is large compared to the boundary layer thickness.

description: We obtain the leading order corrections to the effective action of an M5-brane wrapping a Riemann surface in the eleven-dimensional supergravity Omega-background. The result can be identified with the first order epsilon-deformation of the Seiberg-Witten effective action of pure SU(2) gauge theory. We also comment on the second order corrections and the generalization to arbitrary gauge group and matter content.

Base pressure measurements of circular cylinders at Reynolds numbers from 100 to 3 x [...] were obtained in a low speed wind tunnel. Pressure distributions from [...] to [...] were also obtained.

In the Reynolds number region from the first appearance of an unsteady wake to the critical Reynolds number the base pressure coefficient shows two maximums and two minimums. The first maximum (Rd [...] 50) coincides with the first appearance, of the Karman vortex street. The succeeding minimum (Rd [...] 300) probably corresponds to the movement of the onset of transition from the end of the vortex-formation region into the free shear layers. The following maximum (Rd [...] 2200) is accompanied by a small discontinuity in the base pressure curve and a decrease in the Strouhal number. The final minimum corresponds to the end of the Schiller-Linke region, at which point transition to turbulence occurs in the free shear layers very near to the shoulder of the cylinder.

A comparison of the blockage correction theories of Maskell and Allen and Vincenti was made at [...] = 6 x [...]. The value of the base pressure coefficient in an unlimited stream at this Reynolds number was found to be [...] = -1.215 for cylinders of one particular roughness, though this value depends on other unit Reynolds number effects. These effects can also result in a significant Reynolds number shift of the base pressure coefficients.
The SWAP test and the Hong-Ou-Mandel effect are equivalent

description: We show that the Hong-Ou-Mandel effect from quantum optics is equivalent to the SWAP test, a quantum information primitive which compares two arbitrary states. We first derive a destructive SWAP test that doesn't need the ancillary qubit that appears in the usual quantum circuit. Then, we study the Hong-Ou-Mandel effect for two photons meeting at a beam splitter and prove it is, in fact, an optical implementation of the destructive SWAP test. This result offers both an interesting simple realization of a powerful quantum information primitive and an alternative way to understand and analyse the Hong-Ou-Mandel effect.

Subjects: Chemistry

description: I.  A new technique utilizing the electro-optic frequency switching of a single mode ( 6 Mhz) dye laser was used to observe free induction decay and optical nutation in iodine gas and optical nutation in an organic mixed crystal (pentacene in p-terphenyl) at low temperature. A new technique, incoherent resonance decay (IRO) was also developed. These experiments allow one to determine T_1 and T_2, the longitudinal and transverse relaxation times of the excited ensemble, in analogy with magnetic resonance. For I_2(g) at O∙C; T_l = 2.3 x 10^(-7) sec, T_2 ≃  1 x 10^(-7) sec.  These techniques are limited to a time scale > 10 nsec.

II.  The construction and characterization of "cw", mode-locked dye laser capable of putting out a continuous train of reproducible sub-picosecond pulses is described. Experiments utilizing this laser for the measurement of picosecond coherent transients and time resolved absorption spectroscopy are proposed.
Simultaneous least squares fitter based on the Lagrange multiplier method

description: We developed a least squares fitter used for extracting expected physics parameters from the correlated experimental data in high energy physics. This fitter considers the correlations among the observables and handles the nonlinearity using linearization during the $χ^2$ minimization. This method can naturally be extended to the analysis with external inputs. By incorporating with Lagrange multipliers, the fitter includes constraints among the measured observables and the parameters of interest. We applied this fitter to the study of the $D^{0}-\bar{D}^{0}$ mixing parameters as the test-bed based on MC simulation. The test results show that the fitter gives unbiased estimators with correct uncertainties and the approach is credible.

Gauging the Way to MFV

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a UV complete model with a gauged flavor symmetry which approximately realizes holomorphic Minimal Flavor Violation (MFV) in R-parity violating (RPV) supersymmetry. Previous work has shown that imposing MFV as an ansatz easily evades direct constraints and has interesting collider phenomenology. The model in this work spontaneously breaks the flavor symmetry and features the minimum "exotic" field content needed to cancel anomalies. The flavor gauge bosons exhibit an inverted hierarchy so that those associated with the third generation are the lightest. This allows low energy flavor constraints to be easily satisfied and leaves open the possibility of flavor gauge bosons accessible at the LHC. The usual MSSM RPV operators are all forbidden by the new gauge symmetry, but the model allows a purely "exotic" operator which violates both R-parity and baryon number. Since the exotic fields mix with MSSM-like right handed quarks, diagonalizing the full mass matrix after flavor-breaking transforms this operator into the trilinear baryon number violating operator UDD with flavor coefficients all suppressed by three powers of Yukawa couplings. There is a limit where this model realizes exact MFV; we compute corrections away from MFV, show that they are under theoretical control, and find that the model is viable in large regions of parameter space.

Generalized Gibbs Ensemble for Heisenberg Spin Chains

Year: 2013

description: We consider the Generalized Gibbs Ensemble (GGE) in the context of global quantum quenches in XXZ Heisenberg spin chains. Embedding the GGE into the Quantum Transfer Matrix formalism we develop an iterative procedure to fix the Lagrange-multipliers and to calculate predictions for the long-time limit of short-range correlators. The main idea is to consider truncated GGE's with only a finite number of charges and to investigate the convergence of the numerical results as the truncation level is increased. As an example we consider a quantum quench situation where the system is initially prepared in the Néel state and then evolves with an XXZ Hamiltonian with anisotropy Delta>1. We provide predictions for short range correlators and gather numerical evidence that the iterative procedure indeed converges. The results show that the system retains memory of the initial condition, and there are clear differences between the numerical values of the correlators as calculated from the purely thermal and the Generalized Gibbs ensembles.

description: We study the effects of non-trivial initial quantum states for inflationary fluctuations within the context of the effective field theory for inflation constructed by Cheung et al. which allows us to discriminate between different initial states in a model-independent way. We develop a Green's function/path integral based formulation that incorporates initial state effects and use it to address questions such as how state-dependent is the consistency relation for the bispectrum, how many e-folds beyond the minimum required to solve the cosmological fine tunings of the big bang are we allowed so that some information from the initial state survives until late times, among others. We find that the so-called consistency condition relating the local limit of the bispectrum and the slow-roll parameter is a state-dependent statement that can be avoided for physically consistent initial states either with or without initial non-Gaussianities.

description: We present the integrated polarization properties of the four compact radio sources 3C48, 3C138, 3C147 and 3C286, from 1 to 50 GHz, over a 30-year time frame spanning 1982 to 2012. These four sources are commonly used as flux density and polarization calibrators for cm-wave interferometers. Using the polarized emission of Mars, we have determined that the true position angle of the linearly polarized emission of 3C286 rises from 33 degrees at 8 GHz to 36 degrees at 45 GHz. There is no evidence for a change in the position angle over time. Using these values, the position angles of the intergrated polarized emission from the other sources are determined as a function of frequency and time. The fractional polarization of 3C286 is found to be slowly rising, at all frequencies, at a rate of ~0.015%/year. The fractional polarizations of 3C48, 3C138, and 3C147 are all slowly variable, with the variations clearly correlated with changes in the total flux densities of these sources.
