Approximate Treatment of Hermitian Effective Interactions and a Bound on the Error
R. Okamoto, K. Suzuki, P. J. Ellis +3
The Hermitian effective interaction can be well-approximated by (R+R^dagger)/2 if the eigenvalues of omega^dagger omega are small or state-independent(degenerate), where R is the s…
Finite Temperature Many-Body Theory with the Lipkin Model
S. Y. Tsay Tzeng, P. J. Ellis, T. T. S. Kuo +1
We have compared exact numerical results for the Lipkin model at finite temperature with Hartree-Fock theory and with the results of including in addition the ring diagrams. In the…
Neutron Stars and Nuclei in the Modified Relativistic Hartree Approximation
M. Prakash, P. J. Ellis, E. K. Heide +1
We have examined the properties of neutron-rich matter and finite nuclei in the modified relativistic Hartree approximation for several values of the renormalization scale, , ar…
