description: We perform a detailed analysis of several mu-tau lepton flavour violating (LFV) processes, namely tau --> mu X (X = gamma, e+ e-, mu+ mu-, rho, pi, eta, eta'), Z --> mu tau and Higgs boson decays into mu tau. First we present a model independent operator analysis relevant to such decays, then we explicitly compute the LFV operator coefficients [and (g_μ-2)] in a general unconstrained MSSM framework, allowing slepton mass matrices to have large mu-tau entries. We systematically study the role and the interplay of dipole and non-dipole operators, showing how the rates and the mutual correlations of those LFV decays change in different regions of the MSSM parameter space.Values of the LFV branching ratios in the experimentally interesting range 10^{-9}-10^{-7} can be achieved. For at least two MSSM Higgs bosons, the branching ratio of the LFV decay into mu tau can reach values of order 10^{-4}.

The Nature of the Massive Young Stars in W75 N

description: We have observed the W75 N massive star forming region in SiO(J=2-1 & J=1-0) at 3" - 5" resolution and in 6 cm, 2 cm, and 7 mm continuum emission at 1.4" - 0.2" resolution. The abundance ratio of [SiO]/[H2] is roughly 5-7 x 10^-11 which is typical for what is expected in the ambient component of molecular clouds with active star formation. The SiO morphology is diffuse and centered on the positions of the ultracompact HII regions - no collimated, neutral jet was discovered. The ionized gas surrounding the protostars have emission measures ranging from 1-15 x 10^6 pc cm^-6, densities from 0.4-5 x 10^4 cm^-3, and derived spectral types of the central ionizing stars ranging from B0.5 to B2. Most of the detected sources have spectral indicies which suggest optically thin to moderately optically thick HII regions produced by a central ionizing star. The spread in ages between the oldest and youngest early-B protostars in the W75 N cluster is 0.1-5 x 10^6 years. This evolutionary timescale for W75 N is consistent with that found for early-B stars born in clusters forming more massive stars (Mstar > 25 Msun).

description: Electron transport phenomena in disordered electron systems with spin-orbit coupling in two dimensions and below are studied numerically. The scaling hypothesis is checked by analyzing the scaling of the quasi-1D localization length. A logarithmic increase of the mean conductance is also confirmed. These support the theoretical prediction that the two dimensional metal in systems with spin-orbit coupling has a perfect conductivity. Transport through a Sierpinski carpet is also reported.

description: We present a general expression for the association rate for partially diffusion-controlled reactions between spherical molecules with an asymmetric reactive patch on each surface. Reaction can occur only if the two patches are in contact and properly aligned to within specified angular tolerances. This extends and generalizes previous approaches that considered only axially symmetric patches; the earlier solutions are shown to be limiting cases of our general expression. Previous numerical results on the rate of protein-protein association with high steric specificity are in very good agreement with the value computed from our analytic expression. Using the new expression, we investigate the influence of orientational constraints on the rate constant. We find that for angular constraints of ~5-15 degrees, a typical range for example in the case of protein-protein interactions, the reaction rate is about 2 to 3 orders of magnitude higher than expected from a simple geometric model.

description: In superconductors with singlet pairing, the inhomogeneous Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state is expected to be stabilized by a large Zeeman splitting. We develop an efficient method to evaluate the Landau-Ginzburg free energies of FFLO-state vortex lattices and use it to simplify the considerations that determine the optimal vortex configuration at different points in the phasediagram. We demonstrate that the order parameter spatial profile is completely determined, up to a uniform translation, by its Landau level index n and the vortex Lattice structure and derive an explicit expression for the order parameter spatial profile that can be used to determine n from experimental data.

Collective Modes of an Anisotropic Quark-Gluon Plasma

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

description: We analyze the collective modes of high-temperature QCD in the case when there is an anisotropy in the momentum-space distribution function for the gluons. We perform a tensor decomposition of the gluon self-energy and solve the dispersion relations for both stable and unstable modes. Results are presented for a class of anisotropic distribution functions which can be obtained by stretching or squeezing an isotropic distribution function along one direction in momentum space. We find that there are three stable modes and either one or two unstable modes depending on whether the distribution function is stretched or squeezed. The presence of unstable modes which have exponential growth can lead to a more rapid thermalization and isotropization of the soft modes in a quark gluon plasma and therefore may play an important role in the dynamical evolution.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: It is well-known that Scherk-Schwarz compactifications in string theory have a tachyon in the closed string spectrum appearing for a critical value of a compact radius. The tachyon can be removed by an appropriate orientifold projection in type II strings, giving rise to tachyon-free compactifications. We present explicit examples of this type in various dimensions, including six and four-dimensional chiral examples, with softly broken supersymmetry in the closed sector and non-BPS configurations in the open sector. These vacua are interesting frameworks for studying various cosmological issues. We discuss four-dimensional cosmological solutions and moduli stabilization triggered by nonperturbative effects like gaugino condensation on D-branes and fluxes.

description: This paper investigates the determinants of real interest rates at world and country level. The starting point is the idea that real interest rates re°ect the interaction of desired saving and planned investment, using the framework developed by Barro and Sala-i-Martin (1990) and Barro (1992). The paper updates previous results and extends the analysis to study long real interest rates. We analyse which factors have been responsible for real rate `regime shifts' during 1959 to 1992. We examine the determinants of interest rate di®erentials across ten major industrialised countries and provide estimates of the extent of capital market integration.

An investigation into induction stovetops versus gas stovetops

Publisher: name: The University of British Columbia
Year: 2012

description: Although gas stovetop has been the dominant cooking appliance in the past few decades, they can no longer satisfy the current society’s sustainability standards. Induction stovetop on the other hand is a great sustainable alternative. The focus of this report is a detailed triple-bottom line assessment between gas and induction stovetops that the new Student Union Building at the University of British Columbia will be choosing. To demonstrate validity, information presented in this report is based on library research and expert interviews. The triple-bottom line assessment between the gas and induction stovetops features a combination of environmental, economical, and social analysis. Induction stovetop is environmentally sustainable as it produces no greenhouse gas emission, consumes less energy and eliminates ecological footprint. Economically, the induction stovetop costs 10% less than its gas counterpart. Finally, induction stovetop is socially sustainable since it has negligible side effects, and does not put its users in danger of gas leakage and heat exposure. The advantages of the induction stovetop allow the new UBC Student Union Building to function as a more sustainable unit. As a result, the new SUB can better serve students and teachers providing a more enjoyable experience during their time at UBC.

description: We make two main contributions to the theory of network formation. First, we introduce a new notion of farsighted equilibrium in network formation. In particular, we introduce the notion of a farsightedly basic network, as well as the notion of a farsighted basis. Given the feasible set of networks, the rules governing network formation, and the preferences of individuals, a farsightedly basic network contained in the farsighted basis represents a possible final resting point (or absorbing state) of a network formation process in which agents behave farsightedly. Thus, the set of networks forming a farsighted basis contains networks which are likely to emerge and persist if individuals behave farsightedly. Second, we show that given any set of rules governing network formation and given any profile of individual preferences over the feasible set of networks, there exists a nonempty subset of networks forming a farsighted basis of the network formation process.

description: We explore a new way to simulate quantum field theory, without introducing a spatial lattice. As a pilot study we apply this method to the 3d λϕ^4 model. The regularisation consists of a fuzzy sphere with radius R for the two spatial directions, plus a discrete Euclidean time. The fuzzy sphere approximates the algebra of functions of the sphere with a matrix algebra, and the scalar field is represented by a Hermitian N x N matrix at each time site. We evaluate the phase diagram, where we find a disordered phase and an ordered regime, which splits into phases of uniform and non-uniform order. We discuss the behaviour of the model in different limits of large N and R, which lead to a commutative or to a non-commutative λϕ^4 model in flat space.

description: High-precision analyses are presented for the production of scalar sleptons, selectrons and smuons in supersymmetric theories, at future e+e- and e-e- linear colliders. Threshold production can be exploited for measurements of the selectron and smuon masses, an essential ingredient for the reconstruction of the fundamental supersymmetric theory at high scales. The production of selectrons in the continuum will allow us to determine the Yukawa couplings in the selectron sector, scrutinizing the identity of the Yukawa and gauge couplings, which is a basic consequence of supersymmetry. The theoretical predictions are elaborated at the one-loop level in the continuum, while at threshold non-zero width effects and Sommerfeld rescattering corrections are included. The phenomenological analyses are performed for e+e- and e-e- linear colliders with energy up to about 1 TeV and with high integrated luminosity up to 1 ab^-1 to cover the individual slepton channels separately with high precision.

Subjects: subject: Agricultural and Food Policy

subject: matching
subject: over-investment

description: This paper shows that coordination failure and contractual incompleteness can lead to socially excessive investment. Firms and workers choose investment levels, then enter a stochastic matching process. If investment levels are discrete, and match frictions are low, high-investing workers (firms) impose a negative pecuniary externality on any worker (firm) who cuts investment. Specifically, an agent cutting investment subsequently bargains with a partner with a binding outside option due to the fact that it can easily match with another high investor. The deviant thus bears the full loss in revenue from its action. However, given enough complementarity in investments, when one agent cuts investment it is efficient that its partner also does so. So, only part of the cost saving accrues to the deviant, with the implication that the net private gain to cutting investment is less than the social gain. A similar argument establishes that over-investment can occur when agents are heterogenous i.e. differ in their cost of investing, even if investments are continuous. Then, over-investment occurs because low-cost investors have a private incentive to invest to shift rent away from high-cost investors. Our model can also explain some recent trends in graduate/non-graduate wage differentials.

description: Modulating Function based estimation methods result in non-asymptotic and real-time capable algorithms that are robust with respect to measurement noise. Adapting the modulation kernel to system conditions online occurs in a variety of approaches and results in a challenging realization problem. During the workshop presentation, a Ritz based method for optimizing the condition number of the parameter estimation regressor is shown. Furhtermore, the utilization of Modulating Functions in the context of nonlinear systems is discussed. Finally, a common implementation scheme is presented which results in a time-varying FIR filter gain.

We also examine the role played by smuggling. The results are generally consistent with the theory, when the characteristics of the markets for the goods are taken into account. For neither good do federal excise taxes affect state taxes. Taxes in neighboring states have a significant and large effect in the case of cigarettes, and a much weaker effect in the case of gasoline. we also find that in the setting of cigarette taxes, concerns about cross-border shopping play a more important role than concerns about smuggling.

description: We investigate a possible unified theory of all interactions which is based only on fundamental spinor fields. The vielbein and metric arise as composite objects. The effective quantum gravitational theory can lead to a modification of Einstein's equations due to the lack of local Lorentz-symmetry. We explore the generalized gravity with global instead of local Lorentz symmetry in first order of a systematic derivative expansion. At this level diffeomorphisms and global Lorentz symmetry allow for two new invariants in the gravitational effective action. The one which arises in the one loop approximation to spinor gravity is consistent with all present tests of general relativity and cosmology. This shows that local Lorentz symmetry is tested only very partially by present observations. In contrast, the second possible new coupling is severely restricted by present solar system observations.

description: In connection with the claim made at the Quark Matter 2005 Conference that the Brown-Rho scaling is ruled out by NA60 data we consider dimuon production from semi-central In+In collisions in a full dynamical model. It is shown that if only a modification of the density-dependent $ρ$-mass is allowed, the maximum of dimuon invariant mass spectra is only slightly below experimental one. The additional inclusion of the temperature-dependent modification factor shifts the spectrum maximum toward lower invariant masses making calculation results incompatible with data. A further study is needed to disentangle the BR dropping $ρ$ mass scaling and strong broadening.

Using “residual” self-rated health to provide instrument for spouse’s well-being and allowing controls on individual fixed effects, we find strong evidence of altruism represented by interdependent relationships in the reported well-being found only among spouses, and not by partners in cohabiting union. Panel data also show that the well-being impact resulting from “caring” can be used to predict future income, unemployment, and marital status for the individuals.

description: We consider measurements, described by a positive-operator-valued measure (POVM), whose outcome probabilities determine an arbitrary pure state of a D-dimensional quantum system. We call such a measurement a pure-state informationally complete (PSI-complete) POVM. We show that a measurement with 2D-1 outcomes cannot be PSI-complete, and then we construct a POVM with 2D outcomes that suffices, thus showing that a minimal PSI-complete POVM has 2D outcomes. We also consider PSI-complete POVMs that have only rank-one POVM elements and construct an example with 3D-2 outcomes, which is a generalization of the tetrahedral measurement for a qubit. The question of the minimal number of elements in a rank-one PSI-complete POVM is left open.

description: This paper examines the socio-economic consequences of teenage motherhood for a cohort of British women born in 1970. We employ a number of methods to control for observed and unobserved differences between women who gave birth as a teenager and those who do not. We present results from conventional linear regression models, a propensity score matching estimator, and an instrumental variable estimator that uses miscarriage data to control for unobserved characteristics influencing selection into teenage motherhood. We consider the effects on equivalised family income at age 30, and its constituent parts. We find significant negative effects of teenage motherhood using methods that control only for observed characteristics using linear regression or matching methods. However once unobserved heterogeneity is also taken into account, the evidence for large negative effects becomes much less clear-cut. We look at older and younger teenage mothers separately and find that the negative effects are not necessarily stronger for teenagers falling pregnant before age 18 compared with those falling pregnant between 18 and 20, which could further suggest that some of the negative effects of teenage motherhood are temporary.

description: This note reexamines the single-profile approach to social-choice theory. If an alternative is interpreted as a social state of affairs or a history of the world, it can be argued that a multi-profile approach is inappropriate because the information profile is determined by the set of alternatives. However, single-profile approaches are criticized because of the limitations they impose on the possibility of formulating properties such as anonymity. We suggest an alternative definition of anonymity that applies in a single-profile setting and characterize anonymous single-profile welfarism under a richness assumption.

Jahn-Teller polarons and their superconductivity in a molecular conductor

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We present a theoretical study of a possibility of superconductivity in a three dimensional molecular conductor in which the interaction between electrons in doubly degenerate molecular orbitals and an {\em intra}molecular vibration mode is large enough to lead to the formation of $E\otimes β$ Jahn-Teller small polarons. We argue that the effective polaron-polaron interaction can be attractive for material parameters realizable in molecular conductors. This interaction is the source of superconductivity in our model. On analyzing superconducting instability in the weak and strong coupling regimes of this attractive interaction, we find that superconducting transition temperatures up to 100 K are achievable in molecular conductors within this mechanism. We also find, for two particles per molecular site, a novel Mott insulating state in which a polaron singlet occupies one of the doubly degenerate orbitals on each site. Relevance of this study in the search for new molecular superconductors is pointed out.

Lattice glass model in three spatial dimensions

description: The understanding of thermodynamic glass transition has been hindered by the lack of proper models beyond mean-field theories. Here, we propose a three-dimensional lattice glass model on a simple cubic lattice that exhibits the typical dynamics observed in fragile supercooled liquids such as two-step relaxation, super-Arrhenius growth in the relaxation time, and dynamical heterogeneity. Using advanced Monte Carlo methods, we compute the thermodynamic properties deep inside the glassy temperature regime, well below the onset temperature of the slow dynamics. The specific heat has a finite jump towards the thermodynamic limit with critical exponents close to those expected from the hyperscaling and the random first-order transition theory for the glass transition. We also study an effective free energy of glasses, the Franz--Parisi potential, as a function of the overlap between equilibrium and quenched configurations. The effective free energy indicates the existence of a first-order phase transition, consistent with the random first-order transition theory. These findings strongly suggest that the glassy dynamics of the model has its origin in thermodynamics.

subject: Wage Subsidies Screening

description: This paper explores how to optimally set tax and transfers when taxation authorities: (1) are uninformed about individuals’ value of time in both market and non-market activities and (2) can observe both market-income and time allocated to market employment. In contrast to much of the optimal income taxation literature, we show that optimal redistribution in this environment involves distorting market employment upwards for low net-income individuals through phased-out wage-contingent employment subsidies, and distorting employment downward for high net-income individuals through positive and increasing marginal income tax rate. We also show that workfare may also be used as part of an optimal redistribution program.

description: In a simple finite-horizon overlapping-generations model where the government has the power to levy commodity taxes and to implement uniform lump-sum transfers, and individuals as well as the government can purchase units of a storable good in order to transfer resources from the present to the future, we derive the equations that implicitly define the taxes and subsidies that are part of the second-best Pareto optima. In this context we first show that there is production efficiency. We then show that taxes on capital income/savings are required at almost all Pareto optima. Finally we show that there are no restriction on preferences or technologies that are consistent with a general exemption of capital income/savings from the tax base.

description: This paper characterizes welfarist social evaluation in a multi-profile setting where, in addition to multiple utility profiles, there may be more than one profile of nonwelfare information. We prove a new version of the welfarism theorem in this alternative framework, and we demonstrate that adding a plausible and weak anonymity property to the welfarism axioms generates welfarist social-evaluation orderings that are anonymous

description: We prove that every conceivable hidden variable model reproducing the quantum mechanical predictions of almost any entangled state must necessarily violate Bell's locality condition. The proof does not involve the consideration of any Bell inequality but it rests on simple set theoretic arguments and it works for almost any noncompletely factorizable state vector associated to any number of particles whose Hilbert spaces have arbitrary dimensionality.

description: It has been suggested that space-time might undergo fluctuations because of its intrinsic quantum nature. These fluctuations would pose a fundamental limit to the ability of measuring distances with arbitrary precision, beyond any limitations due to standard quantum mechanics. Laser interferometers have recently been proposed as being suited for a search for the existence of space-time fluctuations. Here we present results of a search for space-time fluctuations of very low fluctuation frequencies, in the range from 1 microHz to 0.5 Hz. Rigid optical interferometers made out of sapphire and operated at cryogenic temperature were used. We find an upper limit of 1.10^-24 Hz^-1 for the normalized distance noise spectral density at 6 microHz, and of 1.10^-28 Hz^-1 above 5 mHz, and establish an experimental limit for the parameter of a recently proposed random-walk hypothesis.

description: We discuss finite-size effects on homogeneous nucleation in first-order phase transitions. We study their implications for cosmological phase transitions and to the hadronization of a quark-gluon plasma generated in high-energy heavy ion collisions. Very general arguments allow us to show that the finite size of the early universe has virtually no relevance in the process of nucleation and in the growth of cosmological bubbles during the primordial quark-hadron and the electroweak phase transitions. In the case of high-energy heavy ion collisions, finite-size effects play an important role in the late-stage growth of hadronic bubbles.
