Two-Body Correlations in Nuclear Systems
Correlations in the nuclear wave-function beyond the mean-field or Hartree-Fock approximation are very important to describe basic properties of nuclear structure. Various approaches to account for such correlations are described and compared to each other. This includes the hole-line expansion, the coupled cluster or “exponential S” approach, the self-consistent evaluation of Greens functions,...
متن کاملNovel correlations in two dimensions: Two-body problem
We discuss a many-body Hamiltonian with twoand three-body interactions in two dimensions introduced recently by Murthy, Bhaduri and Sen. Apart from an analysis of some exact solutions in the many-body system, we analyze in detail the two-body problem which is completely solvable. We show that the solution of the two-body problem reduces to solving a known differential equation due to Heun. We s...
متن کاملTwo-body Correlations and the Underlying Phase Transitions in Bilayers
The pair correlation functions for a bilayer system of classical electrons has been calculated through a two-component HNC formalism. The results show changes in the structure of the correlation functions as the interlayer distance is increased from zero to about twice the Wigner-Seitz radius. These changes are indicative of structural phase transitions which are expected to take place in the c...
متن کاملCorrelations within eigenvectors and transition amplitudes in the two-body random interaction model.
It is shown that the two-body character of the interaction in a many-body system gives rise to specific correlations between the components of compound states, even if this interaction is completely random. Surprisingly, these correlations increase with the increase of the number of active (valence) particles. Statistical theory of transition amplitudes between compound states, which takes into...
