Reduction of the RPA eigenvalue problem and a generalized Cholesky decomposition for real-symmetric matrices
P. Papakonstantinou
The particular symmetry of the random-phase-approximation (RPA) matrix has been utilized in the past to reduce the RPA eigenvalue problem into a symmetric-matrix problem of half th…

Matrix Elements and Few-Body Calculations within the Unitary Correlation Operator Method
R. Roth, H. Hergert, P. Papakonstantinou +2
We employ the Unitary Correlation Operator Method (UCOM) to construct correlated, low-momentum matrix elements of realistic nucleon-nucleon interactions. The dominant short-range c…
