Creation and pinning of vortex-antivortex pairs
(American Physical Society, 2006)
Computer modeling is reported about the creation and pinning of a magnetic vortex-antivortex (V-AV) pair in a superconducting thin film, due to the magnetic field of a vertical magnetic dipole above the film, and two antidot ...
P(t) Dependence of Transverse Flow in Relativistic Heavy-Ion Collisions
(American Physical Society, 1996)
The strength of transverse flow is examined as a function of transverse momentum p(t) using a simple, transversely moving thermal model and a more realistic, relativistic transport model. It is shown that the p(t) dependence ...
Determination of the astrophysical S factor for C-11(p,gamma)N-12 from the N-12 -> C-11+p asymptotic normalization coefficient
(American Physical Society, 2003)
The evolution of very low-metallicity, massive stars depends critically on the amount of CNO nuclei that they produce. Alternative paths from the slow 3alpha process to produce CNO seed nuclei could change their fate. The ...
Effects of (N)over-Barn Polarization on Vector-Meson Masses at Finite-Temperature
(American Physical Society, 1995)
Effects of (N) over bar N polarization on vector meson (rho and omega) masses at finite temperature are studied. Including a reduced nucleon mass in a hot matter, we find that the reduction of vector meson masses due to ...
Partonic coalescence in relativistic heavy ion collisions
(American Physical Society, 2003)
Using a covariant coalescence model, we study hadron production in relativistic heavy ion collisions from both soft partons in the quark-gluon plasma and hard partons in minijets. Including transverse flow of soft partons ...
Search for temperature and N/Z dependent effects in the decay of A=98 compound nuclei
(American Physical Society, 2004)
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 ...
Simple Heuristic Derivation of the Universal Jump in the Superfluid Density of 2-Dimensional Superfluids
(American Physical Society, 1992)
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 ...
Controllable optical switch using a Bose-Einstein condensate in an optical cavity
(American Physical Society, 2011)
The optical bistability of an ultracold atomic ensemble located in a small-volume ultrahigh-finesse optical cavity is investigated. We find that a transverse pumping field can be used to control the bistable behavior of ...
Critical behavior and universality in Levy spin glasses
(American Physical Society, 2011)
Using large-scale Monte Carlo simulations that combine parallel tempering with specialized cluster updates, we show that Ising spin glasses with Levy-distributed interactions share the same universality class as Ising spin ...
Charged particle rapidity distributions at relativistic energies
(American Physical Society, 2001)
Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...
