Abstract: The scaling properties of elliptic flow of hadrons produced in ultrarelativistic heavy-ion collisions are investigated at low transverse momenta, p(T) less than or similar to 2 GeV. Utilizing empirical parametrizations of a thermalized fireball with collective-flow fields, the resonance recombination model (RRM) is employed to describe hadronization via quark coalescence at the hadronization transition. We reconfirm that RRM converts equilibrium quark distribution functions into equilibrated hadron spectra including the effects of space-momentum correlations on elliptic flow. This provides the basis for a controlled extraction of quark distributions of the bulk matter at hadronization from spectra of multistrange hadrons which are beligeved to decouple close to the critical temperature. The resulting elliptic flow from empirical fits at the BNL Relativistic Heavy Ion Collider exhibits transverse kinetic-energy and valence-quark scaling. Utilizing the well-established concept of sequential freeze-out, the scaling at low momenta extends to bulk hadrons (pi, K, p) at thermal freeze-out, albeit with different source parameters compared to chemical freeze-out. Elliptic-flow scaling is thus compatible with both equilibrium hydrodynamics and quark recombination.

Abstract: Identified charged pion, kaon, and proton spectra are used to explore the system size dependence of bulk freeze-out properties in Cu + Cu collisions at root s(NN) = 200 and 62.4 GeV. The data are studied with hydrodynamically motivated blast-wave and statistical model frameworks in order to characterize the freeze-out properties of the system. The dependence of freeze-out parameters on beam energy and collision centrality is discussed. Using the existing results from Au + Au and pp collisions, the dependence of freeze-out parameters on the system size is also explored. This multidimensional systematic study furthers our understanding of the QCD phase diagram revealing the importance of the initial geometrical overlap of the colliding ions. The analysis of Cu + Cu collisions expands the system size dependence studies from Au + Au data with detailed measurements in the smaller system. The systematic trends of the bulk freeze-out properties of charged particles is studied with respect to the total charged particle multiplicity at midrapidity, exploring the influence of initial state effects.

Abstract: Measurements of Be-7 scattering at 87 MeV on a melamine (C3N6H6) target and of B-8 at 95 MeV on C were performed. For Be-7 the angular range was extended over previous measurements and monitoring of the intensity of the radioactive beam was improved. The measurements provide a renormalization of the absolute cross section of existing data on the proton transfer reaction N-14(Be-7,B-8)C-13 and lead to improved optical-model potentials used in the incoming and outgoing channels for the distorted-wave Born approximation analysis. The results yield an updated determination of the asymptotic normalization coefficient for the virtual decay B-8 -> Be-7+p. The new value, C-tot(2)(B-8)=0.466 +/- 0.049 fm(-1), is slightly larger than, but consistent with, the previous result. This implies an astrophysical factor, S-17(0)=18.0 +/- 1.9 eV b, for the solar neutrino-generating reaction Be-7(p, gamma)B-8.

Abstract: Fusion-evaporation reactions induced by 110 MeV B-11 and radioactive C-11 on Rb-87 targets have been studied by measuring evaporation residue-light particle coincidences. The proton to alpha particle ratio in each reaction has been derived and compared with predictions from statistical model calculations. These calculations account rather well for the experimental data, when a small empirical adjustment of the emission barrier is performed, in agreement with earlier results. No evidence is found for predicted temperature and isospin modification of the binding energies. The possibility of a further study of isospin and temperature dependent effects in fusion-evaporation reactions with radioactive beams is discussed.

Abstract: Using a new formalism that modifies a tight-binding Hamiltonian to include interaction with a time-dependent electromagnetic field, we have obtained an analytical expression for the second-order susceptibility. This expression has been used to calculate the energy dependence of X-(2)(omega) for GaAs. The results are in agreement with previous calculations and with available experimental data.

Abstract: We present a procedure for finding the exact solution to the linear-response Boltzmann equation for two-dimensional anisotropic systems and demonstrate it on examples of noncrystalline anisotropic magnetoresistance in a system with spin-orbit interaction. We show that two decoupled integral equations must be solved in order to find the nonequilibrium distribution function up to linear order in the applied electric field. The examples are all based on the Rashba system with charged magnetic scatterers, a system where the nonequilibrium distribution function and anisotropic magnetoresistance can be evaluated analytically. Exact results are compared to earlier widely used approximative approaches. We find circumstances under which approximative approaches may become unreliable even on a qualitative level.

Abstract: The exact ground state of a strongly interacting quantum many-body system can be obtained by evolving a trial state with finite overlap with the ground state to infinite imaginary time. In many cases, since the convergence is exponential, the system converges essentially to the exact ground state in a relatively short time. Thus a short-time evolved wave function can be an excellent approximation to the exact ground state. Such a short-time-evolved wave function can be obtained by factorizing, or splitting, the evolution operator to high order. However, for the imaginary time Schrodinger equation, which contains an irreversible diffusion kernel, all coefficients, or time steps, must be positive. (Negative time steps would require evolving the diffusion process backward in time, which is impossible.) Heretofore, only second-order factorization schemes can have all positive coefficients, but without further iterations, these cannot be used to evolve the system long enough to be close to the exact ground state. In this work, we use a newly discovered fourth-order positive factorization scheme which requires knowing both the potential and its gradient. We show that the resulting fourth-order wave function alone, without further iterations, gives an excellent description of strongly interacting quantum systems such as liquid He-4, comparable to the best variational results in the literature. This suggests that such a fourth-order wave function can be used to study the ground state of diverse quantum many-body systems, including Bose-Einstein condensates and Fermi systems.

Abstract: A systematic study of the resistivity (rho), the Hall coefficients (R(H)), and the magnetic susceptibilities (chi) of the Zr-based paramagnetic amorphous alloys suggests a self-consistent explanation for the frequently observed positive values of R(H) that is based on. the side-jump effect. Measurements for chi, R(H), and rho of (Zr0.64Cu0.36)1-xAlx and chi for (Zr0.50Ni0.50)1-xAlx alloys are presented. The odd behavior of the Hall coefficients of these alloys and the anomalous positive Hall coefficients of paramagnetic Zr-based amorphous alloys can be accounted for in terms of the enhanced spin-orbit interaction, which produces the side-jump effect.

Abstract: The magnetic susceptibilities, resistivities, and Hall coefficients of amorphous Ni0.80-xCrxPo0.20 (0.00 less-than-or-equal-to x less-than-or-equal-to 0.40) alloys are reported. A sip change with temperature of the Hall coefficient for a single paramagnetic amorphous alloy that correlates with the temperature-dependent valence susceptibility has been observed (x = 0.20), indicating that an extraordinary contribution to R(H) is responsible for the positive Hall effect in these paramagnetic alloys. Also, an unexplained relatively large contribution to R(H) that is linear in T has been observed in some of these alloys. A gradual change in magnetic properties with composition from large cluster-dominant phase to Kondo-impurity phase has been observed.

Abstract: A simple heuristic derivation is given for the universal jump in the superfluid density rho(s) at the transition temperature T(c) of a two-dimensional superfluid. It is based on the mathematical equivalence of the Hamiltonians of two systems: (i) a superfluid sandwiched between two parallel boundaries that are boosted adiabatically from rest to a finite velocity, and (ii) a two-dimensional two-component Coulomb gas (considered as a set of parallel line charges in three dimensions), sandwiched between two oppositely charged parallel capacitor plates.
