Charm elliptic flow in relativistic heavy-ion collisions RID A-2398-2009
(American Physical Society, 2005)
Charm elliptic flow in heavy-ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Assuming that the cross section for charm quark scattering with other light quarks is the same ...
Antiferromagnetic domain size and exchange bias
(American Physical Society, 2008)
Using neutron diffraction, we measured the sizes of antiferromagnetic domains in three ferromagnet/antiferromagnet bilayer samples as a function of the magnitude and sign of exchange bias, temperature, and antiferromagnet ...
Kaon Production from Hot and Dense Matter Formed in Heavy-Ion Collisions
(American Physical Society, 1991)
In heavy-ion collisions, kaons can be produced from baryon-baryon, meson-baryon, and meson-meson interactions. Simple meson-exchange models are introduced to study kaon production from these processes in the free space. ...
Fast quantum noise in the Landau-Zener transition
(American Physical Society, 2007)
We show by direct calculation starting from a microscopic model that the two-state system with time-dependent energy levels in the presence of fast quantum noise obeys the master equation. The solution of master equation ...
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 ...
