Single-particle dissipation in TDHF studied from a phase-space perspective
N. Loebl, A. S. Umar, J. A. Maruhn +3
We study dissipation and relaxation processes within the time-dependent Hartree-Fock approach using the Wigner distribution function. On the technical side we present a geometrical…
Time-dependent coupled-cluster method for atomic nuclei
D. A. Pigg, G. Hagen, H. Nam +1
We study time-dependent coupled-cluster theory in the framework of nuclear physics. Based on Kvaal's bi-variational formulation of this method [S. Kvaal, arXiv:1201.5548], we expli…
Microscopic sub-barrier fusion calculations for the neutron star crust
A. S. Umar, V. E. Uberacker, C. J. Horowitz
Fusion of very neutron rich nuclei may be important to determine the composition and heating of the crust of accreting neutron stars. Fusion cross sections are calculated using tim…
Microscopic study of CaCa fusion
R. Keser, A. S. Umar, V. E. Oberacker
We investigate the fusion barriers for reactions involving Ca isotopes , , and $\mathrm{^{48}Ca}+\mathrm{^{48}…
