We present a new, efficient method for calculating correlation energy within the random-phase approximation, which is crucial for understanding nuclear physics. This approach offers numerical advantages for realistic nuclear models.

Area of Science:

  • Nuclear Physics
  • Quantum Chemistry
  • Computational Physics

Background:

  • The random-phase approximation (RPA) is a key theoretical framework for describing correlations in quantum many-body systems.
  • Accurate evaluation of correlation energy is essential for predicting nuclear properties, especially in exotic nuclei.
  • Existing methods for RPA correlation energy calculation can be computationally intensive.

Purpose of the Study:

  • To develop an exact and numerically efficient scheme for evaluating correlation energy in the RPA.
  • To provide a computationally advantageous alternative to existing contour integral methods.
  • To demonstrate the applicability of the new scheme to realistic nuclear systems.

Main Methods:

  • Development of a novel scheme based on linear response theory.
