Correlation energies by the generator coordinate method: computational aspects for quadrupolar deformations
M. Bender, G. Bertsch, P. -H. Heenen
We investigate truncation schemes to reduce the computational cost of calculating correlations by the generator coordinate method based on mean-field wave functions. As our test nu…
Variational RPA for the Mie resonance in jellium
G. F. Bertsch, C. Guet, K. Hagino
The surface plasmon in simple metal clusters is red-shifted from the Mie frequency, the energy shift being significantly larger than the usual spill-out correction. Here we develop…
Generator Coordinate Truncations
K. Hagino, G. F. Bertsch, P. -G. Reinhard
We investigate the accuracy of several schemes to calculate ground-state correlation energies using the generator coordinate technique. Our test-bed for the study is the inter…
Nuclear level statistics: extending the shell model theory to higher temperatures
Y. Alhassid, G. F. Bertsch, L. Fang
The Shell Model Monte Carlo (SMMC) approach has been applied to calculate level densities and partition functions to temperatures up to ~ 1.5 - 2 MeV, with the maximal temperature…
