On the foundations of partially quenched chiral perturbation theory

description: It has been widely assumed that partially quenched chiral perturbation theory is the correct low-energy effective theory for partially quenched QCD. Here we present arguments supporting this assumption. First, we show that, for partially quenched QCD with staggered quarks, a transfer matrix can be constructed. This transfer matrix is not Hermitian, but it is bounded, and it can be used to construct correlation functions in the usual way. Combining these observations with an extension of the Vafa--Witten theorem to the partially quenched theory allows us to argue that the partially quenched theory satisfies the cluster property. By extending Leutwyler's analysis of the unquenched case to the partially quenched theory, we then conclude that the existence and properties of the transfer matrix as well as clustering are sufficient for partially quenched chiral perturbation theory to be the correct low-energy theory for partially quenched QCD.

description: The $(2+1)$-d U(1) quantum link model is a gauge theory, amenable to quantum simulation, with a spontaneously broken SO(2) symmetry emerging at a quantum phase transition. Its low-energy physics is described by a $(2+1)$-d $\RP(1)$ effective field theory, perturbed by a dangerously irrelevant SO(2) breaking operator, which prevents the interpretation of the emergent pseudo-Goldstone boson as a dual photon. At the quantum phase transition, the model mimics some features of deconfined quantum criticality, but remains linearly confining. Deconfinement only sets in at high temperature.

Columnar antiferromagnetic order and spin supersolid phase on the extended Shastry-Sutherland lattice

description: We use large scale quantum Monte Carlo simulations to study an extended version of the canonical Shastry-Sutherland model -- including additional interactions and exchange anisotropy -- over a wide range of interaction parameters and an applied magnetic field. The model is appropriate for describing the low energy properties of some members of the rare earth tetraborides. Working in the limit of large Ising-like exchange anisotropy, we demonstrate the stabilization of columnar antiferromagnetic order in the ground state at zero field and an extended magnetization plateau at 1/2 the saturation magnetization in the presence of an applied longitudinal magnetic field -- qualitatively similar to experimentally observed low-temperature phases in ErB$_4$. Our results show that for an optimal range of exchange parameters, a spin supersolid ground state is realized over a finite range of applied field between the columnar antiferromagnetic phase and the magnetization plateau. The full momentum dependence of the longitudinal and transverse components of the static structure factor is calculated in the spin supersolid phase to demonstrate the simultaneous existence of diagonal and off-diagonal long-range order. Our results will provide crucial guidance in designing further experiments to search for the interesting spin supersolid phase in ErB$_4$.

description: The energy deposition and redistribution in hot Jupiter atmospheres is not well understood currently, but is a major factor for their evolution and survival. We present a time dependent radiative transfer model for the atmosphere of WASP-18b which is a massive (10 MJup) hot Jupiter (Teq ~ 2400 K) exoplanet orbiting an F6V star with an orbital period of only 0.94 days. Our model includes a simplified parametrisation of the day-to-night energy redistribution by a modulation of the stellar heating mimicking a solid body rotation of the atmosphere. We present the cases with either no rotation at all with respect to the synchronously rotating reference frame or a fast differential rotation. The results of the model are compared to previous observations of secondary eclipses of Nymeyer et al. (2011) with the Spitzer Space Telescope. Their observed planetary flux suggests that the efficiency of heat distribution from the day-side to the night-side of the planet is extremely inefficient. Our results are consistent with the fact that such large day-side fluxes can be obtained only if there is no rotation of the atmosphere. Additionally, we infer light curves of the planet for a full orbit in the two Warm Spitzer bandpassses for the two cases of rotation and discuss the observational differences.

Optimization and Stability of TCP/IP with Delay-Sensitive Utility Functions

description: TCP/IP can be interpreted as a distributed primal-dual algorithm to maximize aggregate utility over source rates.  It has recently been shown that an equilibrium of TCP/IP, if exists, maximize the same aggregate utility function over both source rates and routes, provided pure congestion prices are used as link costs in the shortest-path calculation of IP.  Moreover, the utility functions are delay-insensitive, i.e., they are functions of rates only.  We extend this result in several ways.

First, we show that if utility functions are delay-insensitive, then there are networks for which TCP/IP optimizes aggregate utility only if routing is based on pure congestion prices. Routing based on the weighted sum of congestion prices and propagation delays optimizes aggregate utility for general networks only if the utility functions are delay-sensitive. Moreover, we identify such a class of delay-sensitive utility functions that is implicitly optimized by TCP/IP. As for the delay-insensitive case, we show for this class of utility functions, equilibrium of TCP/IP exists if and only if the optimization problem has zero duality gap. In that case, there is no penalty for not splitting the traffic.  We exhibit some counter-intuitive properties of this class of utility functions. We also prove that any class of delay-sensitive utility functions that are optimized by TCP/IP necessarily possess some strange properties.

We prove that, for general networks, if the weight on congestion prices is small enough, only minimum-propagation-delay paths are selected.  Hence if all source-destination pairs have unique minimum-propagation-delay paths, then equilibrium of TCP/IP exists and is asymptotically stable.  For general networks, their equilibrium properties are the same as a modified network where paths with non-minimum propagation delays are deleted and routing is based on pure congestion prices.

It is commonly believed that there is generally an inevitable tradeoff between utility maximization and stability in TCP/IP networks.  In particular, as the weight on congestion prices increases, the routing will change from stable to unstable.  We exhibit a counterexample where routing changes from stable to unstable and then to stable again, as the weight on congestion prices increases. Moreover, one can construct a network with any given utility profile as a function of the weight on congestion prices.

description: Spectral efficiency is a key design issue for all wireless communication systems. Orthogonal frequency division multiplexing (OFDM) is a very well-known technique for efficient data transmission over many carriers overlapped in frequency. Recently, several papers have appeared which describe spectrally efficient variations of multi-carrier systems where the condition of orthogonality is dropped. Proposed techniques suffer from two weaknesses: Firstly, the complexity of generating the signal is increased. Secondly, the signal detection is computationally demanding. Known methods suffer either unusably high complexity or high error rates because of the inter-carrier interference. This work addresses both problems by proposing new transmitter and receiver arch itectures whose design is based on using the simplification that a rational Spectrally Efficient Frequency Division Multiplexing (SEFDM) system can be treated as a set of overlapped and interleaving OFDM systems. The efficacy of the proposed designs is shown through detailed simulation of sys tems with different signal types and carrier dimensions. The decoder is heuristic but in practice produces very good results which are close to the theoretical best performance in a variety of settings. The system is able to produce efficiency gains of up to 20% with negligible impact on the required signal to noise ratio.

description: Larger-scale acquisition programs are always daunting in their size and complexity. Whether they are developing commercial or government systems, they are hard to manage successfully under the best of circumstances. If (or when) things begin to go poorly, however, program-management staff will need every tool at their disposal to get things back on track. One of those tools is conducting an assessment of the program, which variously may be called an independent technical assessment (ITA), an independent program assessment (IPA), or a red team; or may simply be a review, investigation, evaluation, or appraisal. Whatever the name, the goal of such activities is to produce objective findings about the state of a program, and recommendations for improving it. Assessments are an indispensable way for a program or project management office (PMO) to try to get an accurate understanding of how things are going and what actions can be taken to make things better. If you’re considering sponsoring such an assessment for your project or program, this blog post provides 12 useful rules to follow to make sure it gets done right, based on our experience at the SEI in conducting system and software assessments of large defense and federal acquisition programs.

description: The dependence of the spin pumping efficiency and the spin mixing conductance on the surface processing of yttrium iron garnet (YIG) before the platinum (Pt) deposition has been investigated quantitatively. The ferromagnetic resonance driven spin pumping injects a spin polarized current into the Pt layer, which is transformed into an electromotive force by the inverse spin Hall effect. Our experiments show that the spin pumping effect indeed strongly depends on the YIG/Pt interface condition. We measure an enhancement of the inverse spin Hall voltage and the spin mixing conductance of more than two orders of magnitude with improved sample preparation.

description: Ever since E.Cartan in the 1920s enriched the geometric framework of general relativity (GR) by introducing a {\it torsion} of spacetime, the question arose whether one could find a measurement technique for detecting the presence of a torsion field. Mao et al.(2007) claimed that the rotating quartz balls in the gyroscopes of the Gravity Probe B experiment, falling freely on an orbit around the Earth, should "feel" the torsion. Similarly, March et al.(2011) argue with the precession of the Moon and the Mercury and extend later their considerations to the Lageos satellite.--- A consistent theory of gravity with torsion emerged during the early 1960's as gauge theory of the Poincaré group. This Poincaré gauge theory of gravity incorporates as simplest viable cases the Einstein-Cartan(-Sciama-Kibble) theory (EC), the teleparallel equivalent GR|| of GR, and GR itself. So far, PG and, in particular, the existence of torsion have {\it not} been experimentally confirmed. However, PG is to be considered as the standard theory of gravity with torsion because of its very convincing gauge structure.--- Since the early 1970s up to today, different groups have shown more or less independently that torsion couples only to the {\it elementary particle spin} and under no circumstances to the orbital angular momentum of test particles. This is established knowledge and we reconfirm this conclusion by discussing the energy-momentum law of PG, which has same form for all versions of PG. Therefore, we conclude that, unfortunately, the investigations of Mao et al. and March et al. do not yield any information on torsion.

description: We address the dynamics of entanglement and quantum discord for two non interacting qubits initially prepared in a maximally entangled state and then subjected to a classical colored noise, i.e. coupled with an external environment characterized by a noise spectrum of the form $1/f^α$. More specifically, we address systems where the Gaussian approximation fails, i.e. the sole knowledge of the spectrum is not enough to determine the dynamics of quantum correlations. We thus investigate the dynamics for two different configurations of the environment: in the first case the noise spectrum is due to the interaction of each qubit with a single bistable fluctuator with an undetermined switching rate, whereas in the second case we consider a collection of classical fluctuators with fixed switching rates. In both cases we found analytical expressions for the time dependence of entanglement and quantum discord, which may be also extended to a collection of flcutuators with random switching rates. The environmental noise is introduced by means of stochastic time-dependent terms in the Hamiltonian and this allows us to describe the effects of both separate and common environments. We show that the non-Gaussian character of the noise may lead to significant effects, e.g. environments with the same power spectrum, but different configurations, give raise to opposite behavior for the quantum correlations. In particular, depending on the characteristics of the environmental noise considered, both entanglement and discord display either a monotonic decay or the phenomena of sudden death and revivals. Our results show that the microscopic structure of environment, besides its noise spectrum, is relevant for the dynamics of quantum correlations, and may be a valid starting point for the engineering of non-Gaussian colored environments.

Experimental study of the burning rates of some solid propellants by using a closed bomb

Year: 1947

description: This report represents an attempt to correlate experimental data obtained with a burning rate bomb with the data obtained from the firing of rocket charges, and to obtain burning rate curves for new propellants where insufficient data exists.

It was found that very good agreement could be obtained between experimental data obtained in a burning rate bomb and data derived from test firing of rocket charges.

A comparison was made among three different propellants which utilized Thiokol LP-3 for the fuel, and potassium perchlorate and ammonium perchlorate, separately or in combination, for the oxidizer. It was found that potassium perchlorate only gave the fastest burning rate, and the ammonium perchlorate only gave the slowest burning rate, while a mixture of the two gave an intermediate value.

An investigation was made on the coning of solid propellant charges. Coning is the term applied when the burning of a solid propellant charge forms a conical burning surface. Normally a flat burning surface is expected and desired. It was found that a wide deviation in the burning rates existed between the center of the propellant and the edge in the case of the mixture of the ammonium and potassium perchlorate and the pure ammonium perchlorate oxidizers. The results also showed that the difference in burning rates between the center and edge of the charge increased as the amount of ammonium perchlorate in the oxidizer was increased. The limited investigation seemed to indicate that the fundamental variation in burning rate was the only cause of coning.

Best results were obtained from the use of a restricting material similar in nature to the propellant being investigated. In this case, a Thiokol restricting material gave the best results on the Thiokol propellants.
Current Sheets and Collisionless Damping in Kinetic Plasma Turbulence

description: We present the first study of the formation and dissipation of current sheets at electron scales in a wave-driven, weakly collisional, 3D kinetic turbulence simulation. We investigate the relative importance of dissipation associated with collisionless damping via resonant wave-particle interactions versus dissipation in small-scale current sheets in weakly collisional plasma turbulence. Current sheets form self-consistently from the wave-driven turbulence, and their filling fraction is well correlated to the electron heating rate. However, the weakly collisional nature of the simulation necessarily implies that the current sheets are not significantly dissipated via Ohmic dissipation. Rather, collisionless damping via the Landau resonance with the electrons is sufficient to account for the measured heating as a function of scale in the simulation, without the need for significant Ohmic dissipation. This finding suggests the possibility that the dissipation of the current sheets is governed by resonant wave-particle interactions and that the locations of current sheets correspond spatially to regions of enhanced heating.

Magnetic survey of the San Gabriel Wash

Year: 1944
Subjects: subject: Geology
subject: FOS: Earth and related environmental sciences

description: As a partial fulfillment of the requirements in obtaining a degree of Master of Science in Geological Sciences at the California Institute of Technology, the writer was given the task of writing a thesis on the following subject: “Magnetic Survey and interpretation of the results over the San Gabriel wash.”

The area is between Monrovia and Azusa, two miles west of Azusa. It is accessible by several roads branching from Foothill Boulevard (U.S. Highway 66) running east and west, passing through Monrovia and Azusa. One of them is the Las Lomas Road going north along the west bank; the other one is an oiled road going to the Cyanide Company plant and continuing as a dirt road along the east bank. The upper part of the wash and the canyon itself can be reached by the State Highway 39 running northward from Azusa. From this road several dirt roads branch out.

The wash is too large to make a detailed survey in a short time. Thus, the work done is more or less a reconnaissance survey. It is surrounded by farms, the Cyanide Company plant, private properties and impenetrable jungle-like areas, so that it has not been possible to take readings anywhere. Another disadvantage is that the running water is controlled by the dam, and sometimes it cannot be crossed, due to abundance and speed of water. Big granite boulders covering the whole wash constitute still another disadvantage, making tripod setting very difficult.

The work was carried on under the directions of Dr. G.W. Potapenko, Associate Professor of Physics, whose assistance is gratefully acknowledged by the writer.

description: We compare two different probes of the expansion history of the universe, namely, luminosity distances from type Ia supernovae and angular diameter distances from galaxy clusters, using the Bayesian interpretation of Crossing statistic [1, 2] in conjunction with the assumption of cosmic duality relation. Our analysis is conducted independently of any a-priori assumptions about the nature of dark energy. The model independent method which we invoke searches for inconsistencies between SNIa and galaxy cluster data sets. If detected such an inconsistency would imply the presence of systematics in either of the two data sets. Simulating observations based on expected WFIRST supernovae data and X-ray eROSITA + SZ Planck cluster data, we show that our method allows one to detect systematics with high precision and without advancing any hypothesis about the nature of dark energy.

description: PART I

An understanding of the possible influence of supersaturated liquids upon the production and refining of petroleum is of industrial interest. Only limited information is available as to the influence of environment upon the duration of supersaturation for pure hydrocarbons and their mixtures.

A number of measurements were made of the influence of strain upon the behavior of four mixtures of methane and n-decane at temperatures ranging from 70 [degrees] to 390[degrees] F. The mixtures exhibited equilibrium bubble-point pressures between 54 and 1048 pounds per square inch. The local strain was introduced by raising the temperature of a portion of the system above that of the remainder.

The formation of bubbles in such systems appears to be randomly distributed in time and its rate is nearly directly proportional to the volume of the phase. The results indicate markedly greater tendency for the persistence of supersaturation than obtained in a pure hydrocarbon but the probability of formation of a bubble under a given condition of strain decreased with an increase in mole fraction methane.

PART II

An understanding of the influence of volume and surface effects upon the duration of supersaturation in hydrocarbon liquids is necessary to describe the behavior of liquids in a strained state. A very limited amount of information is available on the influence of surface and volume upon supersaturation in pure hydrocarbons.

Preliminary information in this field was obtained using a mixture of methane and n-decane containing 0.2290 mole fraction methane at 220[degrees] F. The mixture exhibited an equilibrium bubble-point pressure at 220[degrees] F. of 949 pounds per square inch. These measurements were made in equipment in which the strain was introduced by raising the temperature of a portion of the system above that of the remainder.

The volume and surface area of the liquid phase under strain were varied by the introduction of silica crystals. The degree of supersaturation which may be realized in such systems was found to be nearly directly proportional to the volume of the phase. The data were insufficient in number to establish the effect of surface area on bubble formation.

Evaporation constants and the ratios of flame to droplet radii have been calculated for the following monopropellants burning in an inert atmosphere: hydrogen peroxide, nitromethane, hydrazine, ethylene oxide, ozone and nitrous oxide. Compared with the results of similar calculations for fuels burning in air, much smaller flame radii were obtained, while the evaporation constants were found to fall in the same range as before.

Attempts at burning single droplets of monopropellants (e.g. hydrazine and nitromethane) in a nitrogen atmosphere were unsuccessful. Monopropellant droplets burning stably in air were found to extinguish if the oxygen was removed during burning. These experimental findings probably reflect the well-known difficulties encountered in monopropellant operation, which is usually successful only if a suitable reaction catalyst is available. The applicability of calculated monopropellant burning rates to practical cases cannot be assessed at this time.

Single droplets of hydrazine and nitromethane were burnt in air and evaporation constants determined experimentally. The measured rate for nitromethane was found to be in good agreement with calculated results for heterogeneous burning of fuel droplets in air. The measured rate for hydrazine was found to be considerably higher than the value calculated for fuel droplets burning in air or for monopropellant droplets burning in an inert atmosphere. This latter result probably indicates that the assumption of a diffusion flame for the burning of hydrazine in air is not valid, i.e., the hydrazine decomposes throughout the region between the liquid surface and the "flame surface" rather than reacting instantaneously at the "flame surface".

description: The rocks of this area range in age from the pre-Cambrian Pelona schist to the Recent alluvium. This metamorphic formation is separated from the two sedimentary formations by a formation of two igneous intrusives, which have been faulted into their position between the Pelona schist and the Sespe (Oligocene?) formation, the igneous rock, granodiorite and leucomonzonite, caused the extreme tilting of the Sespe when they were faulted into their present position. These rocks are probably of Jura-Cretaceous age. The Sespe is a thick series (approx. 4000 ft.) of continental deposits, now in a more or less consolidated condition. The Lower Upper Miocene Mint Canyon formation is another continental: series deposited unconformably upon the Sespe. It consists, in the lower section, of coarse conglomerates, sandstones and shales with some ash beds in the upper part which show some volcanic activity during Upper Miocene times. The region then underwent some folding and gentle tilting in post- Miocene times and a mature land surface was formed. There was a deposition of terrace material in probably Pleistocene time after which the region suffered continuous uplifting until the present time.

description: A random phase property is proposed for products of random matrices drawn from any one of the classical groups associated with the ten Cartan symmetry classes of non-interacting disordered Fermion systems. It allows to calculate the Lyapunov spectrum explicitly in a perturbative regime. These results apply to quasi-one-dimensional random Dirac operators which can be constructed as representatives for each of the ten symmetry classes. For those symmetry classes that correspond to two-dimensional topological insulators or superconductors, the random Dirac operators describing the one-dimensional boundaries have vanishing Lyapunov exponents and almost surely an absolutely continuous spectrum, reflecting the gapless and conducting nature of the boundary degrees of freedom.

Inertial spin Hall effect in noncommutative space

description: In the present paper the study of inertial spin current(that appears in an accelerated frame of reference) is extended to Non-Commutative (NC) space. The $θ$-dependence, ($θ$ being the NC parameter), of the inertial spin current is derived explicitly. We have provided yet another way of experimentally measuring $θ$. Our bound on $θ$ matches with previous results. In Hamiltonian framework, the Dirac Hamiltonian in an accelerating frame is computed in the low energy regime by exploiting the Foldy-Wouthuysen scheme. The NC $θ$-effect appears from the replacement of normal products and commutators by Moyal *-products and *-commutators. In particular, the commutator between the external magnetic vector potential and the potential induced by acceleration becomes non-trivial. Expressions for $θ$-corrected inertial spin current and conductivity are derived. The $θ$ bound is obtained from the out of plane spin polarization, which is experimentally observable.

Repeated loads above the proportional limit on 24ST aluminum alloy

description: The purpose of this investigation is to study the effect of repeated tensile stresses above the proportional limit on 24ST Aluminum Alloy.

The investigation consisted of two parts: the design and building of testing apparatus which would provide a pure tension stress capable of being repeated many times a minute without shock but with a high rate of loading, and to obtain data by means of runs on prepared samples of the metal under study.

It was found that permanent deformation caused by overstress is not a useful factor in forecasting life expectancy.

It was also found that the effects of "aging" (elapsed time between overstresses), initial cold work, and magnitude of over- stresses applied all have definite influence on the ability of 24ST Aluminum Alloy to withstand further overstressing and require more thorough investigation.

It is considered that this field offers attractive possibilities for further study of the behavior of aircraft materials above the proportional limit with an eye toward increasing accuracy of airplane design.

The investigation was carried out at the Daniel Guggenheim Aeronautical Laboratory, California Institute of Technology, Pasadena, California.

description: We demonstrate the effectiveness of a generalized renormalized perturbational approach to calculate the induced magnetization for the single impurity Anderson model with a strong on-site interaction, using flow equations for renormalized parameters to scale from a weak correlation to a strong correlation regime. We show that, using simple approximation schemes in different parameter regimes, remarkably accurate results can be obtained for all magnetic field values by comparing the results with those from direct numerical renormalization group and Bethe ansatz calculations.

Comments on double field theory and diffeomorphisms

description: As the theory is subject to a section condition, coordinates in double field theory do not represent physical points in an injective manner. We argue that a physical point should be rather one-to-one identified with a `gauge orbit' in the coordinate space. The diffeomorphism symmetry then implies an invariance under arbitrary reparametrizations of the gauge orbits. Within this generalized sense of diffeomorphism, we show that a recently proposed tensorial transformation rule for finite coordinate transformations is actually (i) consistent with the standard exponential map, and further (ii) compatible with the full covariance of the `semi-covariant' derivatives and curvatures after projectors are properly imposed.

The measurement of gas produced by electrical power arcs in insulating oil
Creators: name: Kuo, Tsao Hwa
Publisher: name: California Institute of Technology
Year: 1957
Subjects: Electrical Engineering

description: This thesis presents a study of the factors which influence the gas rate (volume of gas produced per unit arc energy) in insulating oil. Such data are fundamental to the design of oil circuit breakers. It is found that the gas rate varies with electrode length, location of arc on the surface, duration of current and material of arcing surface. The gas rate is higher for the longer gap length (3/4 inch) than for the shorter gap length (1/4 inch). An arc on the center of the surface generally gives a lower gas rate while that on the edge a higher gas rate. For arcs occurring on the center, copper surface has a higher gas rate while steel and silver elkalite (alloy used in practice) surfaces have approximately the same lower rate. A high gas rate results in the short duration arc of 1/2 cycle and nearly equal low gas rates are obtained for durations of 2 cycles and 3 1/2 cycles. No appreciable change in gas rate is observed as the magnitude of current peak varies from 400 to 800 amperes.

With the method used in this research, steel surfaces have the desired character that arcs always occur on the center. For 600 amperes and 2 cycle duration, the gas rate of flat steel surfaces referred to 760 mm and 25[degrees]C is 74, 133 and 175 cubic centimeters per kilowatt second at 1/4, 1/2 and 3/4 inch gap lengths respectively.

Because the gas rate for silver elkalite and steel surfaces are about the same with arcs on the center, the effect of current magnitude is small and the arc duration in most circuit breaker operation about 2 cycles, the total volume of gas produced in actual operation of a circuit breaker can be calculated approximately by correlating the above figures with field test records of arc energy and electrode travel.

description: We study the contribution of the antisymmetric tensor unparticle mediation to the diphoton production rate of the Higgs boson and try to explain the discrepancy between the measured value of the decay width of the discovered new resonance and that of the standard model Higgs boson. We observe that tree level contribution of the antisymmetric unparticle mediation is a possible candidate to explain the measured value of the diphoton decay rate.
