Analysis of quantum correlations within the ground state of a three level Lipkin model
Javier Faba, Vicente MartÃn, Luis Robledo
The performance of beyond mean field methods in solving the quantum many body problem for fermions is usually characterized by the correlation energy measured with respect to the u…
Correlation energy and quantum correlations in a solvable model
Javier Faba, Vicente MartÃn, Luis Robledo
Typically in many-body systems the correlation energy, which is defined as the difference between the exact ground state energy and the mean-field solution, has been a measure of t…
Description of the asymmetric to symmetric fission transition in the neutron-deficient Thoriums -- Role of the tensor force
Remi Bernard, Nathalie Pillet, Luis Robledo +1
In the present study, we have investigated the impact of the tensor force on fission paths, in particular the symmetric and asymmetric barriers in 230 Th, 226 Th, 222 Th and 216 Th…
Direct Evidence for Octupole Deformation in Ba and the Origin of Large Moment Variations in Reflection-Asymmetric Nuclei
Brian Bucher, Shaofei Zhu, Ching-Yen Wu +24
Despite the more than one order of magnitude difference between the measured dipole moments in Ba and Ba, the strength of the octupole correlations in Ba ar…
Two-orbital quantum discord in fermion systems
Javier Faba, Vicente MartÃn, Luis Robledo
A simple expression to compute the quantum discord between two orbitals in fermion systems is derived using the parity superselection rule. As the correlation between orbitals depe…
Future of Nuclear Fission Theory
Michael Bender, Remi Bernard, George Bertsch +30
There has been much recent interest in nuclear fission, due in part to a new appreciation of its relevance to astrophysics, stability of superheavy elements, and fundamental theory…
