Neutron-induced astrophysical reaction rates for translead nuclei
I. V. Panov, I. Yu. Korneev, T. Rauscher +4
Neutron-induced reaction rates, including fission, are calculated in the temperature range 1.d8 <T (K) < 1.d10 within the framework of the statistical model for targets with atomic…
Pi-phases in balanced fermionic superfluids on spin-dependent optical lattices
I. Zapata, B. Wunsch, N. T. Zinner +1
We study a balanced two-component system of ultracold fermions in one dimension with attractive interactions and subject to a spin-dependent optical lattice potential of opposite s…
Effective Potential for Ultracold Atoms at the Zero-Crossing of a Feshbach Resonance
N. T. Zinner
We consider finite-range effects when the scattering length goes to zero near a magnetically controlled Feshbach resonance. The traditional effective-range expansion is badly behav…
Thomas-Fermi Approximation for a Condensate with Higher-order Interactions
M. Thøgersen, N. T. Zinner, A. S. Jensen
We consider the ground state of a harmonically trapped Bose-Einstein condensate within the Gross-Pitaevskii theory including the effective-range corrections for a two-body zero-ran…
Stability of a BEC with Higher-order Interactions near a Feshbach Resonance
N. T. Zinner, M. Thøgersen
We consider the stability of an ultracold trapped Bose-Einstein condensate near a Feshbach resonance. Using a modified Gross-Pitaevskii equation that includes higher-order terms an…
Mapping the Two-Component Atomic Fermi Gas to the Nuclear Shell-Model
C. Özen, N. T. Zinner
The physics of a two-component cold fermi gas is now frequently addressed in laboratories. Usually this is done for large samples of tens to hundreds of thousands of particles. How…
