Whence the odd-even staggering in nuclear binding?
W. A. Friedman, G. F. Bertsch
We explore the systematics of odd-even mass staggering with a view to identifying the physical mechanisms responsible. The BCS pairing and mean field contributions have A- and numb…
Odd-even mass differences from self-consistent mean-field theory
G. F. Bertsch, C. A. Bertulani, W. Nazarewicz +2
We survey odd-even nuclear binding energy staggering using density functional theory with several treatments of the pairing interaction including the BCS, Hartree-Fock-Bogoliubov,…
Conductance of a single-atom carbon chain with graphene leads
Wei Chen, A. V. Andreev, G. F. Bertsch
We study the conductance of an interconnect between two graphene leads formed by a single-atom carbon chain. Its dependence on the chemical potential and the number of atoms in the…
Collectivity-induced quenching of signatures for shell closures
M. Bender, G. F. Bertsch, P. -H. Heenen
Mass differences are an often used as signature and measure for shell closure. Using the angular-momentum projected Generator Coordinate Method and the Skyrme interaction SLy4, we…
Accuracy of BCS-based approximations for pairing in small Fermi systems
N. Sandulescu, G. F. Bertsch
We analyze the accuracy of BCS-based approximations for calculating correlation energies and odd-even energy differences in 2-component fermionic systems with a small number of pai…
Hartree-Fock-Bogoliubov Theory of Polarized Fermi Systems
George Bertsch, Jacek Dobaczewski, Witold Nazarewicz +1
Condensed Fermi systems with an odd number of particles can be described by means of polarizing external fields having a time-odd character. We illustrate how this works for Fermi…
