Spin Scissors Mode and the Fine Structure of M1 States in Nuclei
Spin Scissors Mode M1 States Fine Structure
2011/7/20
The coupled dynamics of low lying modes, including the scissors mode, and various giant quadrupole resonances are studied with the help of the Wigner Function Moments method generalized to take into a...
Sub-barrier capture with quantum diffusion approach: actinide-based reactions
astrophysical S-factor dissipative dynamics sub-barrier capture
2011/7/20
With the quantum diffusion approach the behavior of capture cross sections and mean-square angular momenta of captured systems are revealed in the reactions with deformed nuclei at subbarrier energies...
Level spacing of U(5) \leftrightarrow SO(6) transitional region with maximum likelihood estimation method
Level spacing of U leftrightarrow SO maximum likelihood estimation method
2011/7/20
In this paper,a systematic study of quantum phase transition within U(5) \leftrightarrow SO(6) limits is presented in terms of infinite dimensional Algebraic technique in the IBM framework. Energy lev...
Strangeness Production close to Threshold in Proton-Nucleus and Heavy-Ion Collisions
Production close to Threshold Proton-Nucleus Heavy-Ion Collisions
2011/7/20
We discuss strangeness production close to threshold in p+A and A+A collision. Comparing the body of available K+, K0, K-, and Lambda data with the IQMD transport code and for some key observables as ...
This paper gives a momentum-space representation of the Argonne V18 potential as an expansion in products of spin-isospin operators with scalar coefficient functions of the momentum transfer. Two repr...
Embedded Representations and Quasi-Dynamical Symmetry
Embedded Representations Quasi-Dynamical Symmetry
2011/7/20
This presentation explains why models with a dynamical symmetry often work extraordinarily well even in the presence of large symmetry breaking interactions. A model may be a caricature of a more real...
Uncertainties in nuclear transition matrix elements for neutrinoless $ββ$ decay II: the heavy Majorana neutrino mass mechanism
matrix elements neutrino mass mechanism
2011/7/20
Employing four different parametrization of the pairing plus multipolar type of effective two-body interaction and three different parametrizations of Jastrow-type of short range correlations, the unc...
A fully relativistic lattice Boltzmann algorithm
Relativistic fluid dynamics Quark-gluon plasmas Lattice Boltzmann
2011/7/20
Starting from the Maxwell-Juettner equilibrium distribution, we develop a relativistic lattice Boltzmann (LB) algorithm capable of handling ultrarelativistic systems with flat, but expanding, spacetim...
We estimate the energy loss of a fast gluon propagating in a gluonic fluid due to the radiative process: gg -> ggg by relaxing some of the approximations used in previous works.
Spectral distribution method for neutrinoless double-beta decay nuclear transition matrix elements: Binary correlation results
neutrinoless double-beta decay nuclear transition
2011/7/20
Neutrinoless double-beta decay nuclear transition matrix elements are generated by an effective two-body transition operator and it consists of Gamow-Teller like and Fermi like (also tensor) operators...
Photon-tagged heavy meson production in high energy nuclear collisions
Photon-tagged heavy meson production high energy nuclear collisions
2011/7/21
We study the photon-triggered light and heavy meson production in both p+p and A+A collisions. We find that a parton energy loss approach that successfully describes inclusive hadron attenuation in nu...
Nucleon-Nucleon Correlations and Gribov Inelastic Shadowing in High Energy Collisions
short-range correlations Gribov inelastic shadowing high-energy collisions
2011/1/7
The effects of nucleon-nucleon (NN) short range correlations (SRC) and Gribov inelastic
shadowing (IS) in high energy collisions are illustrated.
We determine the energy-level shift experienced by a neutral atom due the quantum electromagnetic interaction with a layered dielectric body. We use the technique of normal-mode expansion to quantize...

2010/10/29
We present a general and relatively efficient method for decomposing an arbitrary exponential operator of bosonic mode operators into a set of universal logic gates. Our work is mainly oriented toward...
