Current response, structure factor and hydrodynamic quantities of a two- and three-dimensional Fermi gas from the operator product expansion
Current response structure factor
2011/7/21
We apply the operator product expansion to determine the asymptotic form of the current response of a Fermi gas in two and three dimensions.
Structure of scalar mesons and the Higgs sector of strong interaction
Structure of scalar mesons Higgs sector strong interaction
2011/7/21
The scalar mesons $\sigma(600)$, $\kappa(800)$, $f_0(980)$ and $a_0(980)$ together with the pseudo Goldstone bosons $\pi$, $K$, and $\eta$ may be considered as the Higgs sector of strong interaction.
We investigate the linear-chain configurations of four-$\alpha$ clusters in $^{16}$O using a Skyrme cranked Hartree-Fock method and discuss the relationship between the stability of such states and an...
Three-dimensional calculation of inhomogeneous structure in low-density nuclear matter

2011/7/20
In low-density nuclear matter which is relevant to the crust region of neutron stars and collapsing stage of supernovae, non-uniform structures called "nuclear pasta" are expected.
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...
High-spin structure of odd $^{71-81}$Ga isotopes with shell model

2011/7/20
The recently measured experimental data of Argonne National Laboratory for high-spin states in neutron-rich $^{71,73,75,77}$Ga isotopes have been interpreted in the framework of large-scale shell mode...
Comment on "Nuclear structure corrections in muonic deuterium"
Nuclear structure muonic deuterium Atomic Physics
2011/8/3
Abstract: A recent letter [1] investigated the effects of deuteron polarizability in the mu D atom. The importance of understanding this atom has been heightened because of the possible light it could...
Axial and Vector Structure Functions for Electron- and Neutrino- Nucleon Scattering Cross Sections at all $Q^2$ using Effective Leading order Parton Distribution Functions
Axial Vector Structure Functions Electron- Neutrino- Nucleon Scattering Cross Sections all $Q^2$ Effective Leading Parton Distribution Functions
2010/12/27
We construct a model for inelastic neutrino- and electron-nucleon scattering cross sections using effective leading order parton distribution functions with a new scaling variable $\xi_w$. Non-perturb...

Five-Body Cluster Structure the Double-Lambda Hypernucleus Lambda-Lambda-11Be
2011/1/4
Hiyama et al. [PRL 104 (2010) 212502] have recently reported on a pioneering five-body alpha-alpha-n-Lambda-Lambda cluster-model calculation of Lambda-Lambda-11Be in order to confront a possible inter...
Generalized parton distributions and the parton structure of light nuclei
Generalized parton distributions parton structure of light nuclei
2011/1/6
The measurement of nuclear Generalized Parton Distributions (GPDs)represents a valuable tool to understand the structure of bound nucleons and the phenomenology of hard scattering off nuclei. By using...

Structure spatial distribution fast neutron irradiation
2010/11/23
The influence of fast neutron irradiation on the structure and spatial distribution of Ge nanocrystals (NC) embedded in an amorphous SiO2 matrix has been studied. The investigation was conducted by me...
Scalar field in nuclear matter: the roles of spontaneous chiral symmetry breaking and nucleon structure
nuclear matter roles of spontaneous chiral symmetry breaking nucleon structure
2011/1/6
Chiral theories with spontaneous symmetry breaking such as the Nambu-Jona-Lasinio (NJL)
model lead to the existence of a scalar mode. We present in a detailed manner how the corresponding low momentu...
Shell-model calculations that include both Lambda and Sigma configurations with p-shell cores are used to interpret gamma-ray transitions in Lambda-7Li, -9Be, -10B, -11B, -12C, -15N, and -16O observed...
