Partonic effects on the elliptic flow at relativistic heavy ion collisions
(American Physical Society, 2002)
The elliptic flow in heavy ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. By converting the strings in the high energy density regions into partons, we find that the final ...
Pion interferometry in Au plus Au and Cu plus Cu collisions at s(NN)=62.4 and 200 GeV
(American Physical Society, 2009)
We present a systematic analysis of two-pion interferometry in Au+Au collisions at s(NN)=62.4 GeV and Cu+Cu collisions at s(NN)=62.4 and 200 GeV using the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The ...
Deuteron-nucleus collisions in a multiphase transport model
(American Physical Society, 2003)
Using a multiphase transport model, we study pseudorapidity distributions and transverse momentum spectra in deuteron-gold collisions at RHIC. We find that final-state partonic and hadronic interactions affect the transverse ...
Nuclear modification factor of nonphotonic electrons in heavy-ion collisions, and the heavy-flavor baryon-to-meson ratio
(American Physical Society, 2009)
The nuclear modification factor R(AA) of nonphotonic electrons in Au + Au collisions at root(S)NN = 200 GeV is studied by considering the decays of heavy-flavor hadrons produced in a quark coalescence model. Although an ...
Anisotropic flow in Cu plus Au collisions at root s(N N)=200GeV RID A-2398-2009
(American Physical Society, 2006)
The anisotropic flow of charged hadrons in asymmetric Cu+Au collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Compared with previous results for symmetric Au+Au collisions, charged ...
Analytical and micromagnetic study of a Neel domain wall
(American Physical Society, 2008)
For ferromagnets with exchange, dipolar interaction, and uniaxial anisotropy, by both analytic methods and micromagnetic simulations we study Neel domain walls in thin ferromagnetic strips of finite width. Comparison of ...
Fourth-order diffusion Monte Carlo algorithms for solving quantum many-body problems
(American Physical Society, 2001)
By decomposing the important sampled imaginary time Schrodinger evolution operator to fourth order with positive coefficients, we derived a number of distinct fourth-order diffusion Monte Carlo algorithms. These sophisticated ...
Asymptotic normalization coefficients for B-8 -> Be-7+p from a study of Li-8 -> Li-7+n
(American Physical Society, 2003)
Asymptotic normalization coefficients (ANCs) for Li-8-->Li-7+n have been extracted from the neutron transfer reaction C-13(Li-7,Li-8)C-12 at 63 MeV. These are related to the ANCs in B-8-->Be-7 + p using charge symmetry. ...
Effects of geometry and impurities on quantum rings in magnetic fields RID D-3014-2009
(American Physical Society, 2006)
We investigate the effects of impurities and changing ring geometry on the energetics of quantum rings under different magnetic field strengths. We show that as the magnetic field and/or the electron number are/is increased, ...
