Induced p-wave superfluidity in strongly interacting imbalanced Fermi gases
Induced p-wave superfluidity imbalanced Fermi gases
2010/11/24
The induced interaction among the majority spin species, due to the presence of the minority
species, is computed for the case of a population-imbalanced resonantly-interacting Fermi gas.
SNIF: A Futuristic Neutrino Probe for Undeclared Nuclear Fission Reactors
Neutrino Probe Undeclared Nuclear Fission Reactors
2011/1/10
Today reactor neutrino experiments are at the cutting edge of fundamental research in particle
physics. Understanding the neutrino is far from complete, but thanks to the impressive progress in this ...
Density-dependent nucleon-nucleon interaction from three-nucleon forces
Density-dependent nucleon-nucleon interaction three-nucleon forces
2011/1/6
Microscopic calculations based on realistic nuclear hamiltonians, while yielding accurate results for the energies of the ground and low-lying excited states of nuclei with A ≤ 12, fail to reproduce t...
Birefringent break up of Dirac fermions in a square optical lattice
Birefringent square optical lattice
2010/11/18
We generalize a proposal by Sørensen et al. [Phys. Rev. Lett. 94, 086803 (2005)] for creating an artificial magnetic field in a cold atom system on a square optical lattice. This leads us to an...
We show that pQCD factorization incorporated with pre-haronization energy-loss effect naturally
leads to flatness of the nuclear modification factor RAA for produced hadrons at high transverse moment...

Novel Term Fermion-Boson Mapping Nuclear Rotation
2011/1/6
We introduce a novel term in fermion-boson mapping method for the Interacting Boson Model
(IBM) for rotational nuclei. The rotation of a given deformed nucleon system is similar to the
corresponding...

Nucleon Delta Omega excited state spectra three pion mass values
2011/1/13
The energies of the excited states of the Nucleon, D and W are computed in lattice QCD, using
two light quarks and one strange quark on anisotropic lattices. The calculations are performed at three v...
Entropic Effect on the Rate of Dislocation Nucleation
Entropic Effect the Rate of Dislocation Nucleation
2010/11/18
Dislocation nucleation is essential to our understanding of plastic deformation, ductility and
mechanical strength of crystalline materials. Molecular dynamics simulation has played an important role...
Coexistence of pairing gaps in three-component Fermi gases
Coexistence of pairing gaps three-component Fermi gases
2010/11/25
We study a three-component superfluid Fermi gas in a spherically symmetric harmonic trap using the Bogoliubov-deGennes method. We predict a coexistence phase in which two pairing field order parameter...
Evolving Nuclear Many-Body Forces with the Similarity Renormalization Group

2011/1/6
In recent years, the Similarity Renormalization Group has provided a powerful and versatile
means to soften interactions for ab initio nuclear calculations. The substantial contribution of both induc...

Nucleon $N^* (1535)$ Distribution Amplitudes
2011/1/13
The QCDSF collaboration has investigated the distribution amplitudes and wavefunction normalization constants of the nucleon and its parity partner, the N∗(1535). We report on recent progress in...

Nuclear symmetry energy subnormal densities measured nuclear masses
2011/1/6
The symmetry energy coefficients for nuclei with mass number A = 20 ∼ 250 are extracted
from more than 2000 measured nuclear masses. With the semi-empirical connection between the
symmetry ene...
