description: As the matching condition in Grover search algorithm is transgressed due to inevitable errors in phase inversions, it gives a reduction in maximum probability of success. With a given degree of maximum success, we have derive the generalized and imroved criterion for tolerated error and corresponding size of quantum database under the inevitable gate imperfections. The vanished inaccurancy to this condition has also been shown. Besides, a concise formula for evaluating minimum number of iterations is also presented in this work.

description: We introduce a -- somewhat holographic -- dictionary between gravitational observables for scattering processes (measured at the "boundary") and adiabatic invariants for bound orbits (in the "bulk"), to all orders in the Post-Minkowskian (PM) expansion. Our map relies on remarkable connections between the relative momentum of the two-body problem, the classical limit of the scattering amplitude and the deflection angle in hyperbolic motion. These relationships allow us to compute observables for generic orbits (such as the periastron advance $ΔΦ$) through analytic continuation, via a radial action depending only on boundary data. A simplified (more geometrical) map can be obtained for circular orbits, enabling us to extract the orbital frequency as a function of the (conserved) binding energy, $Ω(E)$, directly from scattering information. As an example, using the results in Bern et al. [1901.04424, 1908.01493], we readily derive $Ω(E)$ and $ΔΦ(J,E)$ to two-loop orders. We also provide closed-form expressions for the orbital frequency and periastron advance at tree-level and one-loop order, respectively, which capture a series of exact terms in the Post-Newtonian expansion. We then perform a partial PM resummation, using a "no-recoil" approximation for the amplitude. This limit is behind the map between the scattering angle for a test-particle and the two-body dynamics to 2PM. We show that it also captures a subset of higher order terms beyond the test-particle limit. While a (rather lengthy) Hamiltonian may be derived as an intermediate step, our map applies directly between gauge invariant quantities. Our findings provide a starting point for an alternative approach to the binary problem. We conclude with future directions and some speculations on the classical double copy.

description: We use giga-particle N-body simulations to study galaxy cluster populations in Hubble Volumes of LCDM (Omega_m=0.3, Omega_Lambda=0.7) and tCDM (Omega_m=1) world models. Mapping past light-cones of locations in the computational space, we create mock sky surveys of dark matter structure to z~1.4 over 10,000 sq deg and to z~0.5 over two full spheres. Calibrating the Jenkins mass function at z=0 with samples of ~1.5 million clusters, we show that the fit describes the sky survey counts to 5e13 Msun/h). Fitting the observed local temperature function determines the ratio beta of specific thermal energies in dark matter and intracluster gas. We derive a scaling with power spectrum normalization beta \propto sigma8^{5/3}, and measure a 4% error on sigma8 arising from cosmic variance in temperature-limited cluster samples. Considering distant clusters, the LCDM model matches EMSS and RDCS X-ray-selected survey observations under economical assumptions for intracluster gas evolution. Using transformations of mass-limited cluster samples that mimic sigma8 variation, we explore SZ search expectations for a 10 sq deg survey complete above 10^{14} Msun/h. Cluster counts are shown to be extremely sensitive to sigma8 uncertainty while redshift statistics, such as the sample median, are much more stable. For LCDM, the characteristic temperature at fixed sky surface density is a weak function of redshift, implying an abundance of hot clusters at z>1. Assuming constant beta, four kT>8 keV clusters lie at z>2 and 40 kT>5 keV clusters lie at z>3 on the whole sky. Detection of Coma-sized clusters at z>1 violate LCDM at 95% confidence if their surface density exceeds 0.003 per sq deg, or 120 on the whole sky.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The wave function for the quadratic gravity theory derived from the heterotic string effective action is deduced to first order in ${e^{-Φ}\over {g_4^2}}$ by solving a perturbed second-order Wheeler-DeWitt equation, assuming that the potential is slowly varying with respect to $Φ$. Predictions for inflation based on the solution to the second-order Wheeler-DeWitt equation continue to hold for this theory. It is shown how formal expressions for the average paths in minisuperspace $\{< a(t) >, < Φ(t)> \}$ determine the shifts from the classical solutions to $a_{cl}(t)$ and $Φ_{cl}(t)$, which occur only at third order in the expansion of the integrals representing the expectation values.

We describe in quantitative analysis how physical assumptions about the freeze-out geometry and dynamics influence the particle spectra. Considering ratios of $m_\bot$ distribution of resonance-particle ratios (such as $K^*/K$, $Σ^*/Λ, η'/η$) we observe significant sensitivity to fireball freeze-out geometry and flow dynamics.

description: The jet bundle description of time-dependent mechanics is revisited. The constraint algorithm for singular Lagrangians is discussed and an exhaustive description of the constraint functions is given. By means of auxiliary connections we give a basis of constraint functions in the Lagrangian and Hamiltonian sides. An additional description of constraints is also given considering at the same time compatibility, stability and second-order condition problems. Finally, a classification of the constraints in first and second class is obtained using a cosymplectic geometry setting. Using the second class constraints, a Dirac bracket is introduced, extending the well-known construction by Dirac.

description: The $ε$-regime of dilaton chiral perturbation theory is introduced. We compute the dilaton mass, the chiral condensate and the topological susceptibility in the $ε$-regime, as a function of the fermion mass. The microscopic spectral density of the Dirac operator is obtained from dilaton chiral perturbation theory. Our main result is that the chiral condensate and the spectral density are related to their counterparts from ordinary chiral perturbation theory via a simple scaling relation. This relation originates from the mass dependence of the dilaton potential, and is valid in both the $ε$-regime and the $p$-regime. In the $ε$-regime, moreover, all results agree with the universal predictions to leading order in $ε$.

description: The business community must be prepared for a variety of emergencies ranging from natural disasters to terrorist attacks. Additionally, businesses have to be prepared to continue operations with the expectation that it may not be business as usual. For businesses, protection of critical resources is paramount in emergency planning. However, the consideration of employee mobility during and after an emergency is less often considered, although it is an equally significant aspect of businesses continuity. The objective of this paper is to explore how Metropolitan Planning Organizations (MPOs), as coordinators of regional transportation decision-making, can promote regional business continuity after an emergency. The focus of the study is on the role of Transportation Demand Management strategies (TDMs) in supporting employee mobility and business continuity. This paper summarizes the results of a 2008 study commissioned by the Sacramento Area Council of Governments, the MPO for three of California’s urbanized areas. It represents the MPO’s first step towards the development of an emergency management and business continuity plan for its six-county region. Based on 20 interviews with government agencies and private companies across the United States, as well as a review of government and industry publications, the paper highlights best practices—including public-private partnerships, resource sharing protocols, and technology applications—for maintaining employee mobility and business continuity following an emergency situation. The study also presents five case studies based on public and private sector experiences that highlight lessons learned and planning and coordination efforts aimed at supporting employee mobility after an emergency.

We show that the structure of the action and the properties of the gauge invariant observables can be understood in terms of the associated target space equivariant cohomology. We use a de Rham superfield formalism to efficiently explore the implications of the Batalin Vilkoviski master equation.

We also provide some insight to the behavior of the system, by reducing it under special assumptions to systems of ODEs, that can in turn be studied as dynamical systems.

description: In the wake of economic restructuring and decentralization of cities America has come to rely on automobiles, contributing to high levels of traffic congestion, carbon emissions, poor quality places, and a declining public infrastructure. Policymakers and planners recognize that mass transit, an alternative mode of travel, can alleviate America’s strained transportation system. However, public transportation is an infrequently used service for commuters’ work and nonwork related trips. The purpose of this study is to examine the significance and magnitude of large scale forces on travel behavior gauging the influence of demographics, urban area characteristics, and certain dollar values on mass transit travel particularly bus, light/heavy rail systems. In regressing per capita transit trips and per capita miles from the National Transit Database on U.S. Census data across urban areas and over time (2000-2007), significant variables include higher share of young and old age populations, larger household size, car ownership, higher commute times, denser central places, higher government funding, and higher gas prices. These findings illustrate how responsive the use of public transit is to urban area environments and demographic composition. Policy should acknowledge these relationships for environment sustainability, economic competitiveness, and social vibrancy.

The shape of the Red Giant Branch Bump as a diagnostic of partial mixing processes in low-mass stars

description: We suggest to use the shape of the Red Giant Branch (RGB) Bump in metal-rich globular clusters as a diagnostic of partial mixing processes between the base of the convective envelope and the H-burning shell. The Bump located along the differential luminosity function of cluster RGB stars is a key observable to constrain the H-profile inside these structures. In fact, standard evolutionary models that account for complete mixing in the convective unstable layers and radiative equilibrium in the innermost regions do predict that the first dredge-up lefts over a very sharp H-discontinuity at the bottom of the convective region. Interestingly enough we found that both atomic diffusion and a moderate convective overshooting at the base of the convective region marginally affects the shape of the RGB Bump in the differential Luminosity Function (LF). As a consequence, we performed several numerical experiments to estimate whether plausible assumptions concerning the smoothing of the H-discontinuity, due to the possible occurrence of extra-mixing below the convective boundary, affects the shape of the RGB Bump. We found that the difference between the shape of RGB Bump predicted by standard and by smoothed models can be detected if the H-discontinuity is smoothed over an envelope region whose thickness is equal or larger than 0.5 pressure scale heights. Finally, we briefly discuss the comparison between theoretical predictions and empirical data in metal-rich, reddening free Galactic Globular Clusters (GGCs) to constrain the sharpness of the H-profile inside RGB stars.

description: The generic crease set of an event horizon possesses anisotropic structure though most of black holes are dynamically stable. This fact suggests that a generic almost spherical black hole has a very crumpled crease set in a microscopic scale though the crease set is similar to a point-wise crease set in a macroscopic scale. In the present article, we count the number of such micro-states of an almost spherical black hole by analogy with an elastic chain polymer. This estimation of black hole entropy reproduces the well-known Bekenstein-Hawking entropy of a Schwarzschild black hole.

description: In real-life implementations of quantum key distribution (QKD), the physical systems with unwanted imperfections would be exploited by an eavesdropper. Based on imperfections in the detectors, detector control attacks have been successfully launched on several QKD systems, and attracted widespread concerns. Here, we propose a robust countermeasure against these attacks just by introducing a variable attenuator in front of the detector. This countermeasure is not only effective against the attacks with blinding light, but also robust against the attacks without blinding light which are more concealed and threatening. Different from previous technical improvements, the single photon detector in our countermeasure model is treated as a blackbox, and the eavesdropper can be detected by statistics of the detection and error rates of the QKD system. Besides theoretical proof, the countermeasure is also supported by an experimental demonstration. Our countermeasure is general in sense that it is independent of the technical details of the detector, and can be easily applied to the existing QKD systems.

description: In the current era of noisy quantum devices, there is a need for quantum algorithms that are efficient and robust against noise. Towards this end, we introduce the projected cooling algorithm for quantum computation. The projected cooling algorithm is able to construct the localized ground state of any Hamiltonian with a translationally-invariant kinetic energy and interactions that vanish at large distances. The term "localized" refers to localization in position space. The method can be viewed as the quantum analog of evaporative cooling. We start with an initial state with support over a compact region of a large volume. We then drive the excited quantum states to disperse and measure the remaining portion of the wave function left behind. For the nontrivial examples we consider here, the improvement over other methods is substantial. The only additional resource required is performing the operations in a volume significantly larger than the size of the localized state. These characteristics make the projected cooling algorithm a promising tool for calculations of self-bound systems such as atomic nuclei.

description: The 10 km wide Jamuna river in Bangladesh is one of the most morphologically active rivers in the world, with bank erosion rates of up to 500 m per year (Mutton and Haque 2004). Such extreme river migration in the center of Bangladesh, one of the most densely populated and impoverished regions in the world, displaces roughly 60,000 people per year (Mutton and Haque 2004). To alleviate this, the Government of Bangladesh has committed to stabilizing and narrowing it’s major rivers with the Flood and Riverbank Erosion Risk Management Investment Program (FRERMIP) (ADB 2016). FRERMIP is investigating numerous training scenarios and final stabilized widths (4-8 km). These scenarios are combinations of works (spur dikes, dredging) at different locations and activation rates (i.e. construction schedules) which FRERMIP seeks to optimize for cost, navigation, bank erosion prevention and flood mitigation. However, little is understood about how these proposals may affect the sediment balances in Bangladesh. The Jamuna combines with the Ganges and Upper Meghna to form the world’s second largest delta: the Bengal delta. Due to the high sediment load delivered from these Himalayan rivers, accretion rates in the delta have been in the order of 5 km2/yr (Sarker et al. 2011). Changes in the supplied sediment to the delta may reduce this accretion, amplifying the consequences of sea level rise. A better understanding of how proposed trainings will affect the sediment supply to the delta can help decision makers weigh the pros and cons of implementation, and prepare for these impacts on the delta

description: The unitary Fermi gas is a many-body system of two-component fermions with zero-range interactions tuned to infinite scattering length. Despite much activity and interest in unitary Fermi gases and its universal properties, there have been great difficulties in performing accurate calculations of the superfluid condensate fraction and pairing wave function. In this work we present auxiliary-field lattice Monte Carlo simulations using a novel lattice interaction which accelerates the approach to the continuum limit, thereby allowing for robust calculations of these difficult observables. As a benchmark test we compute the ground state energy of 33 spin-up and 33 spin-down particles. As a fraction of the free Fermi gas energy $E_{FG}$, we find $E_0/E_{FG}= 0.369(2), 0.372(2)$, using two different definitions of the finite-system energy ratio, in agreement with the latest theoretical and experimental results. We then determine the condensate fraction by measuring off-diagonal long-range order in the two-body density matrix. We find that the fraction of condensed pairs is $α= 0.43(2)$. We also extract the pairing wave function and find the pair correlation length to be $ζ_pk_F = 1.8(3) \hbar$, where $k_F$ is the Fermi momentum. Provided that the simulations can be performed without severe sign oscillations, the methods we present here can be applied to superfluid neutron matter as well as more exotic P-wave and D-wave superfluids.

description: We experimentally analyzed the statistical errors in quantum-state estimation and examined whether their lower bound, which is derived from the Cramer-Rao inequality, can be truly attained or not. In the experiments, polarization states of bi-photons produced via spontaneous parametric down-conversion were estimated employing tomographic measurements. Using a new estimation strategy based on Akaike's information criterion, we demonstrated that the errors actually approach the lower bound, while they fail to approach it using the conventional estimation strategy.

Landau Ghosts and Anti-Ghosts in Condensed Matter and High Density Hadronic Matter

description: It is observed that the ``ghost'' (originally discovered by Landau in quantum electro-dynamics) and its counterparts in other theories are indeed ubiquitous as they occur in a one-loop approximation to any conventional (unbroken) gauge theory. The mechanism is first exposed in its generality via the Dyson equation and a simple but explicit example in condensed matter is provided through the static Clausius-Mossotti and its dynamic counterpart the Lorenz-Lorentz equation. The physical phase transition phenomenon associated with it is found to be super-radiance. We verify quantitatively that water (and many other polar liquids) are indeed super-radiant at room temperature. In quantum chromo-dynamics on the other hand, we encounter, thanks to asymptotic freedom, an ``anti-ghost'' which is closely associated with color confinement. Thus, in QCD, free quarks and glue exist in a super-radiant phase and hadronic matter in the normal one.

description: In 1992, Pickrell published a seminal piece examining the accuracy of ridership forecasts and capital cost estimates for fixed-guideway transit systems in the US. His research created heated discussions in the transit industry regarding the ability of transit planners to properly plan largescale transit systems. Since then, evidence has arisen to suggest that ridership forecasting and capital cost estimation of both new transit systems and extensions to existing transit system has improved. However, no statistical analysis has been conducted of US transit systems to determine this. This research fills this gap in the literature by examining 47 fixed-guideway transit projects planned in the US between 1972 and 2005 to see whether or not a Pickrell Effect can be observed whereby ridership forecasting and capital cost estimations improved due to Pickrell’s work.

description: We consider two identical oscillators with weak, time delayed coupling. We start with a general system of delay differential equations then reduce it to a phase model. With the assumption of large time delay, the resulting phase model has an explicit delay and phase shift in the argument of the phases and connection function, respectively. Using the phase model, we prove that for any type of oscillators and any coupling, the in-phase and anti-phase phase-locked solutions always exist and give conditions for their stability. We show that for small delay these solutions are unique, but with large enough delay multiple solutions of each type with different frequencies may occur. We give conditions for the existence and stability of other types of phase-locked solutions. We discuss the various bifurcations that can occur in the phase model as the time delay is varied. The results of the phase model analysis are applied to Morris-Lecar oscillators with diffusive coupling and compared with numerical studies of the full system of delay differential equations. We also consider the case of small time delay and compare the results with the existing ones in the literature.

description: Radio Frequency of Identification (RFID) has changed the transportation operation. Many logistics providers have been forcedly implemented to provide their customers’ tracking information in terms of increasing their service levels. As members of the supply chain, many trade partners coincidently have brought out RFID within their internal process under conditions that standards stabilize and component costs fall. From the railroad carriers perspectives, RFID should be adapted to increase their working efficiency and working along with their customers of the supply chain. Railroad carriers should not only provide a lower freight rate but also need to offer better service for tailoring customers’ needs. It would be win-win situation. Under this demanding situation, we used an unconventional concept of Collaborative Transportation Management (CTM) that is the sub concept from the concept of Collaborative Planning, Forecasting, and Replenishment (CPFR) to find the benefit of implementing FRID in the railroad industry. The result could be used for refining business processes and building up the strength by increasing the degree of visibility and decreasing the expenditure for inventory, logistics, and transportation. It would be the dramatic improvement in railroad transportation and encourage all players of the supply chain (SC) to take advantage from RFID.

description: Ultra-light axion-like particle (ULAP) is one of attractive candidates for cold dark matter. Because the de Broglie wavelength of ULAP with mass $\sim 10^{-22} {\rm eV}$ is $\mathcal{O}({\rm kpc})$, the suppression of the small scale structure by the uncertainty principle can solve the core-cusp problem. Frequently, ULAP is assumed to be uniformly distributed in the present universe. In typical ULAP potentials, however, strong self-resonance at the beginning of oscillation invokes the large fluctuations, which may cause the formation of the dense localized object, oscillon. % Such a dense object lives for a long time, it may affect the cosmological evolution. In this paper, we confirm the oscillon formation in a ULAP potential by numerical simulation and analytically derive its lifetime.

description: Our interest is in the cumulative probabilities Pr(L(t) \le l) for the maximum length of increasing subsequences in Poissonized ensembles of random permutations, random fixed point free involutions and reversed random fixed point free involutions. It is shown that these probabilities are equal to the hard edge gap probability for matrix ensembles with unitary, orthogonal and symplectic symmetry respectively. The gap probabilities can be written as a sum over correlations for certain determinantal point processes. From these expressions a proof can be given that the limiting form of Pr(L(t) \le l) in the three cases is equal to the soft edge gap probability for matrix ensembles with unitary, orthogonal and symplectic symmetry respectively, thereby reclaiming theorems due to Baik-Deift-Johansson and Baik-Rains.

description: The Living in Britain Survey, 1983 took the form of a public opinion poll conducted amongst adults in Britain on behalf of London Weekend Television. It formed the basis of the 'Breadline Britain' television series. The survey investigated the public's perceptions of minimum needs and then identifying those who could not afford these necessities. The survey established, for the first time ever, what the majority of people see as the 'necessities of life', covering a wide range of goods and activities. The research found that people judge a minimum standard of living on socially established criteria and not just on the criteria of survival or subsistence.

A good modern guide to the survey is available on the Poverty and Social Exclusion (PSE) project website Breadline Britain 1983 webpages, which also include links to online documents such as the questionnaire, findings reports and Mack and Lansley's 1985 book based on the survey and TV series, 'Poor Britain' (see the Publications section below).
