description: Using the results of a high precision calculation of the solar neutrino survival probability for Earth crossing neutrinos in the case of MSW $ν_e \to ν_{μ(τ)}$ transition solution of the solar neutrino problem, performed in an earlier study, we derive predictions for the one-year averaged day-night (D-N) asymmetry in the deformations of the $e^-$ - spectrum to be measured with the Super - Kamiokande detector, and for the D-N asymmetry in the energy- integrated one year signal in this detector. The asymmetries are calculated for solar $ν_e$ crossing the Earth mantle only, the core and the (mantle + core) for a large representative set of values of the MSW transition parameters $Δm^2$ and $\sin^2 2θ_v$ from the ``conservative'' MSW solution region obtained by taking into account possible uncertainties in the values of the $^8$B and $^7$Be neutrino fluxes. The effect of the uncertainties in the value of the bulk matter density and in the chemical composition of the core, on the D-N asymmetry predictions is discussed. It is shown, in particular, that for $\sin^2 2θ_v \leq 0.013$ the one year average D-N asymmetry for neutrinos crossing the Earth core can be larger than the asymmetry for (only mantle crossing + core crossing) neutrinos by a factor of up to six. Iso - (D-N) asymmetry contours in the $Δm^2 - \sin^2 2θ_v$ plane for the Super - Kamiokande detector are derived in the region $\sin^2 2θ_v \gsim 10^{-4}$ for only mantle crossing, core crossing and (only mantle crossing + core crossing) neutrinos. Our results indicate that the Super - Kamiokande experiment might be able to test the $\sin^2 2θ_v \le 0.01$ region of the MSW solution of the solar neutrino problem by performing selective D-N asymmetry measurements.

The long time behavior of initially separated A+B->0 reaction-diffusion systems with arbitrary diffusion constants

Publisher: name: arXiv
Year: 1996
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We examine the long time behaviour of A+B->0 reaction diffusion systems with initially segregated species A and B. All of our analysis is carried out for arbitrary (positive) values of the diffusion constants $D_A$, $D_B$, and initial concentrations $a_0$ and $b_0$ of A's and B's. We divide the domain of the partial differential equations describing the problem into several regions in which they can be reduced to simpler, solvable equations, and we merge the solutions. Thus we derive general formulae for the concentration profiles outside the reaction zone, the location of the reaction zone center, and the total reaction rate. An asymptotic condition for the reaction front to be stationary is also derived. The properties of the reaction layer are studied in the mean-field approximation, and we show that not only the scaling exponents, but also the scaling functions are independent of $D_A$, $D_B$, $a_0$ and $b_0$.

Measurement of the $B^0_d - \bar{B}{^0_d}$ flavor oscillation frequency and study of same side flavor tagging of B mesons in $p\bar p$ collisions

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: $B^0_d$-$\bar{B}{}^0_d$ oscillations are observed in ``self-tagged'' samples of partially reconstructed $B$ mesons decaying into a lepton and a charmed meson collected in $p\bar p$ collisions at $\sqrt{s} = 1.8$ TeV. A flavor tagging technique is employed which relies upon the correlation between the flavor of $B$ mesons and the charge of nearby particles. We measure the flavor oscillation frequency to be $Δm_d = 0.471 ^{+0.078}_{-0.068} \pm 0.034 ps^{-1}$. The tagging method is also demonstrated in exclusive samples of $B^+_u \to J/ψK^+$ and $B^0_d \to J/ψK^{*0}(892)$, where similar flavor-charge correlations are observed. The tagging characteristics of the various samples are compared with each other, and with Monte Carlo simulations.

description: The effect of static fluctuations in the phase of the order parameter on the normal and superconducting properties of a 2D system with attractive four-fermion interaction has been studied. Analytic expressions for the fermion Green function, its spectral density and the density of states are derived. The resultant single-particle Green function clearly demonstrates non-Fermi liquid behavior. The results show that as the temperature increases through the 2D critical temperature the width of the quasiparticle peaks broadens significantly. At the same time one retains the gap in quasiparticle spectrum. The spectral density for the dynamical fluctuations can also be obtained. Clearly the dynamical fluctuations fill the gap giving the observed pseudogap behaviour.

description: Recent results for the finite-temperature static and dynamical properties of the planar $t-J$ model, obtained by a novel numerical method for small correlated systems, are reviewed. Of particular interest are $T>0$ charge and spin response functions: optical conductivity $σ(ω)$ and spin susceptibility $χ(\vec q,ω)$, which show very universal features at intermediate doping. In spin dynamics the universality is best seen in the local spin correlation function, which appears to be $T$-independent and only weakly doping dependent. Results apply directly to the inelastic neutron scattering and to the NMR relaxation experiments in cuprates. Analysing $σ(ω)$ we find that the current correlation function $C(ω)$ is nearly $T$- and moreover $ω$-independent in the regime $T

Using a density matrix formalism, we derive equations of motion which go beyond MFT and provide accurate predictions for the quantum break-time. The leading quantum corrections appear as decoherence of the reduced single-particle quantum state.

Designing Organizations for Sustainable Futures: Identifying interventions that empower employees to promote sustainable practices within the companies they work for
Creators: name: Francovich, Christine
Publisher: name: Carnegie Mellon University
Year: 2021
Subjects: Design

description: We are facing a climate crisis. Yet, the adoption of environmentally- conscious business practices is not happening as fast as the urgency of the situation requires. !e prevalent thought about who is responsible for the solution of climate change is twofold; either the expectation is that governments will step up to enforce climate policy or the pressure is placed on consumers to do the right thing. There is a third opportunity that isn’t discussed as often: shifting the business practices of large corporations. This thesis asks: How might interventions be designed to empoweremployees to find new and engaging ways to promotesustainability practices within their organization? The research borrows from transition design and explores the wicked problem of sustainable business through a holistic systems lens. Firstly, it aims to understand how we have historically viewed and understood climate change and why it is so difficult to shift to a system towards sustainability. !rough understanding the past and current state, a solid foundation is built to explore what a preferred state of business could look like and what barriers need to be overcome to get to that preferred state. To do this, this thesis explores behaviour change theories such as slow change interaction design (Siegel & Beck, 2014), design for learning experiences (Dirksen, 2011) as well as grassroot activism and bottom-up intrapreneurial approaches such as emergent strategy (Brown, 2017). Ultimately, the goal is to leverage design as an agent for positive change by providing clarity on a possible point of intervention that may nudge and incentivize employees to step up and call their business to fight for climate action. The result of this thesis are design principles that could guide the design of future interventions as well as an initial concept exploration. Theproposed intervention encourages collaboration between employees and helps them seek a deeper understanding of their business in order for them to learn how to identify areas of improvement in regards to sustainability. It proposes various learning exercises they could do to gain that understanding, but it is also an invitation for furthercollaboration and development. Because climate change can only be solved together.
Lepton Flavour Violation in a Left-Right Symmetric Model

description: We consider in this paper a Left-Right symmetric gauge model in which a global lepton-number-like symmetry is introduced and broken spontaneously at a scale that could be as low as 10^4 GeV or so. The corresponding physical Nambu-Goldstone boson, which we call majoron and denote J, can have tree-level flavour-violating couplings to the charged fermions, leading to sizeable majoron-emitting lepton-flavour-violating weak decays. We consider explicitly a leptonic variant of the model and show that the branching ratios for μ-> e+J, τ-> e + J and τ-> μ+ J decays can be large enough to fall within the sensitivities of future μand τfactories. On the other hand the left-right gauge symmetry breaking scale may be as low as few TeV.

Kinked Entropy and Discontinuous Microcanonical Spontaneous Symmetry Breaking
Creators: name: Zhou, Hai-Jun
Publisher: name: arXiv
Year: 2019
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Spontaneous symmetry breaking (SSB) in statistical physics is a macroscopic collective phenomenon. For the paradigmatic Q-state Potts model it means a transition from the disordered color-symmetric phase to an ordered phase in which one color dominates. Existing mean field theories imply that SSB in the microcanonical statistical ensemble (with energy being the control parameter) should be a continuous process. Here we study microcanonical SSB on the random-graph Potts model, and discover that the entropy is a kinked function of energy. This kink leads to a discontinuous phase transition at certain energy density value, characterized by a jump in the density of the dominant color and a jump in the microcanonical temperature. This discontinuous SSB in random graphs is confirmed by microcanonical Monte Carlo simulations, and it is also observed in bond-diluted finite-size lattice systems.

description: We present a current and charge conserving theory for the low frequency admittance of a quantum point contact. We derive expressions for the electrochemical capacitance and the displacement current. The latter is determined by the {\em emittance} which equals the capacitance only in the limit of vanishing transmission. With the opening of channels the capacitance and the emittance decrease in a step-like manner in synchronism with the conductance steps. For vanishing reflection, the capacitance vanishes and the emittance is negative.

Abstract

No matter where we are, weather shapes our lives. We are all familiar with ordinary everyday weather concerns, do I need an umbrella when I step out the door today or maybe how cold will it be, will I need to wear a jacket later? Businesses use it to track long-term patterns and understand historical trends. Major media organisations use historical weather data to tell stories by visualising the data to show the effects of climate change to the public. Agricultural researchers use weather data in their analyses to help explain experimental results or build complex models that simulate farming systems. And governments use the data to prepare and plan for future disasters or understand seasonal trends to ensure adequate infrastructure is in place. While the uses are often critical, and the data may be freely or openly available, getting the data quickly and easily into R can be frustrating. There are 193 members of the World Meteorological Organisation (WMO), many of which offer some sort of programmatic access to historical weather data or forecasted weather data via APIs, but some do not, while there are other non-member organisations that do. I'll present the good, the bad and the ugly of different weather data sources and getting the data wrangled and tamed ready to go in your R session with what you need to think about for end users of the data when you make a weather data API client R package to help make our world more understandable.

description: We perform a simplified Ethernet traffic simulation in order to clarify the physical mechanism of the phase transition behavior which has been experimentally observed in the flow density fluctuation of Internet traffic. In one phase traffics from nodes connected with an Ethernet cable are mixed, and in the other phase, the nodes alternately send bursts of packets. The competition of sending packets among nodes and the binary exponential back-off algorithm are revealed to play important roles in producing $1/f$ fluctuations at the critical point.

Setting the boundary parameter to be a special value, we find a higher spin reflecting K-matrix for the supersymmetric t-J model. By using the Quantum Inverse Scattering Method, we obtain the eigenvalue and the corresponding Bethe ansatz equations.

description: An experiment of thermal convection with significant compressible effects is presented. The high-gravity environment of a centrifuge and the choice of xenon gas enable us to observe an average adiabatic temperature gradient up to 3.5 K cm$^{-1}$ over a 4 cm high cavity. At the highest rotation rate investigated, 9990 rpm, the superadiabatic temperature difference applied to the gas layer is less than the adiabatic temperature difference. The convective regime is characterized by a large Rayleigh number, about 10$^{12}$, and dominant Coriolis forces (Ekman number of order 10$^{-6}$). The analysis of temperature and pressure fluctuations in our experiments shows that the dynamics of the flow is in a quasi-geostrophic regime. Still, a classical power law (exponent 0.3 $\pm$ 0.04) is observed between the Nusselt number (dimensionless heat flux) and the superadiabatic Rayleigh number (dimensionless superadiabatic temperature difference). However, a potential hysteresis is seen between this classical high flux regime and a lower heat flux regime. It is unclear whether this is due to compressible or Coriolis effects. In the transient regime of convection from an isothermal state, we observe a local decrease of temperature which can only be explained by adiabatic decompression.
Differential (2+1) Jet Event Rates and Determination of alpha_s in Deep Inelastic Scattering at HERA

description: Events with a (2+1) jet topology in deep-inelastic scattering at HERA are studied in the kinematic range 200 < Q^2< 10,000 GeV^2. The rate of (2+1) jet events has been determined with the modified JADE jet algorithm as a function of the jet resolution parameter and is compared with the predictions of Monte Carlo models. In addition, the event rate is corrected for both hadronization and detector effects and is compared with next-to-leading order QCD calculations. A value of the strong coupling constant of alpha_s(M_Z^2)= 0.118+- 0.002 (stat.)^(+0.007)_(-0.008) (syst.)^(+0.007)_(-0.006) (theory) is extracted. The systematic error includes uncertainties in the calorimeter energy calibration, in the description of the data by current Monte Carlo models, and in the knowledge of the parton densities. The theoretical error is dominated by the renormalization scale ambiguity.

The algebraic properties of the classical null-plane description are generalized to this quantum deformation. In particular, the classical isotopy subalgebra of the null-plane is deformed into a Hopf subalgebra, and deformed spin operators having classical commutation rules can be defined. Quantum Hamiltonian, mass and position operators are studied, and the null-plane evolution is expressed in terms of a deformed Schrödinger equation.

description: A theory of the dynamical conductance of mesoscopic conductors is presented. It is applied to mesoscopic capacitors, resonant double barriers, ballistic wires, metallic diffusive wires, and to the Corbino disk and the Hall bar in quantizing magnetic fields. Central to this approach is a discussion of the charge and potential distribution in mesoscopic conductors. It is necessary to take into account the implications of the long-range Coulomb interaction in order to obtain a charge and current conserving theory. We emphasize the low-frequency response. This has the advantage that the approach is of considerable generality. The theory can be used to discuss the self-consistency of the dc-conductance formula. The theory can also be applied to discuss the rectifying (nonlinear) behavior of mesoscopic conductors.

description: We present high-time-resolution photometry and phase-resolved spectroscopy of the short-period ($P_\mathrm{orb} = 80.52\,\mathrm{min}$) cataclysmic variable SDSS J123813.73-033933.0, observed with the $\mathit{Hubble}$ $\mathit{Space}$ $\mathit{Telescope}$ $\mathit{(HST)}$, the $\mathit{Kepler/K2}$ mission and the Very Large Telescope (VLT). We also report observations of the first detected super-outburst. SDSS J1238-0339 shows two types of variability: quasi-regular brightenings recurring every $\simeq 8.5$ h during which the system increases in brightness by $\simeq 0.5$mag, and a double hump quasi-sinusoidal modulation at the orbital period. The detailed $\mathit{K2}$ light curve reveals that the amplitude of the double-humps increases during the brightenings and that their phase undergoes a $\simeq 90^{\circ}$ phase shift with respect to the quiescent intervals. The $\mathit{HST}$ data unambiguously demonstrate that these phenomena both arise from the heating and cooling of two relatively large regions on the white dwarf. We suggest that the double-hump modulation is related to spiral shocks in the accretion disc resulting in an enhanced accretion rate heating two localised regions on the white dwarf, with the structure of the shocks fixed in the binary frame explaining the period of the double humps. The physical origin of the 8.5 h brightenings is less clear. However, the correlation between the observed variations of the amplitude and phase of the double-humps with the occurrence of the brightenings is supportive of an origin in thermal instabilities in the accretion disc.

description: The peak effect in weakly pinned superconductors is accompanied by metastable vortex states. Each metastable vortex configuration is characterized by a different critical current density J_c, which mainly depends on the past thermomagnetic history of the superconductor. A recent model [G. Ravikumar, et al, Phys. Rev. B 61, R6479 (2000)] proposed to explain the history dependent J_c postulates a stable state of vortex lattice with a critical current density J_c^{st}, determined uniquely by the field and temperature. In this paper, we present evidence for the existence of the stable state of the vortex lattice in the peak effect region of 2H-NbSe_2. It is shown that this stable state can be reached from any metastable vortex state by cycling the applied field by a small amplitude. The minor magnetization loops obtained by repeated field cycling allow us to determine the pinning and "equilibrium" properties of the stable state of the vortex lattice at a given field and temperature unambiguously. The data imply the occurence of a first order phase transition from an ordered phase to a disordered vortex phase across the peak effect.

description: Using a cell dynamic system (CDS) simulation scheme, we investigate the phase-ordering dynamics of non-conserved O(n) models without topological defects, i.e. for $n > d+1$ where $d$ is the spatial dimensionality. In particular, we consider zero-temperature quenches for $d=2$, $n=4,5$, and for $d=1$, $n=3,4,5$. We find, in agreement with previous simulations using fixed-length spins, that dynamical scaling is obtained, with characteristic length $L(t) = t^{1/2}$. We show that the asymptotic behaviour of the structure-factor scaling function $g(q)$ is well fitted by the stretched exponential form $g(q)\sim \exp(-bq^δ)$, with an exponent $δ$ that appears to depend on both n and d. An analytical treatment of an approximate large-N equation for the pair correlation function yields $g(q) \sim q^{-(d-1)/2}\exp(-bq)$, with $b \sim (\ln n)^{1/2}$ for large $n$, in agreement with recent simulations of the same equation.

This article aims to explore the "special alliance" between King Abdullah of Saudi Arabia and women during his reign (2005-2015). In that decade female advancement in the Kingdom emerges as a process resulting from an enlightened Muslim vision and political support to women's needs and rights, according to the Sharī'a. The trajectory explores the ideational, social and economic factors that had an impact on the policies enacted topromote a "flexible approach" founded on the Islamic values of tolerance, equality, mercy, support of knowledge and dialogue. All of that was crucial to give women an unprecedented visibility in Saudi society, and the chance to become active participants in the country's transition toward a knowledge-based society and economy.
