The Two-Body Random Ensemble in Nuclei
T. Papenbrock, H. A. Weidenmueller
Combining analytical and numerical methods, we investigate properties of the two-body random ensemble (TBRE). We compare the TBRE with the Gaussian orthogonal ensemble of random ma…
Density-functional theory for fermions in the unitary regime
T. Papenbrock
In the unitary regime, fermions interact strongly via two-body potentials that exhibit a zero range and a (negative) infinite scattering length. The energy density is proportional…
Density matrix renormalization group and wave function factorization for nuclei
T. Papenbrock, D. J. Dean
We employ the density matrix renormalization group (DMRG) and the wave function factorization method for the numerical solution of large scale nuclear structure problems. The DMRG…
Distribution of spectral widths and preponderance of spin-0 ground states in nuclei
T. Papenbrock, H. A. Weidenmueller
We use a single j-shell model with random two-body interactions to derive closed expressions for the distribution of and the correlations between spectral widths of different spins…
Origin of chaos in the spherical nuclear shell model: role of symmetries
T. Papenbrock, H. A. Weidenmueller
To elucidate the mechanism by which chaos is generated in the shell model, we compare three random-matrix ensembles: the Gaussian orthogonal ensemble, French's two-body embedded en…
Solution of large scale nuclear structure problems by wave function factorization
T. Papenbrock, A. Juodagalvis, D. J. Dean
Low-lying shell model states may be approximated accurately by a sum over products of proton and neutron states. The optimal factors are determined by a variational principle and r…
