Nuclear Structure and Response based on Correlated Realistic NN Interactions
P. Papakonstantinou, R. Roth, H. Hergert +1
Starting from the Argonne V18 nucleon-nucleon (NN) interaction and using the Unitary Correlation Operator Method, a correlated interaction v_UCOM has been constructed, which is sui…
Self-Consistent Description of Collective Excitations in the Unitary Correlation Operator Method
N. Paar, P. Papakonstantinou, R. Roth +1
The fully self-consistent Random Phase Approximation (RPA) is constructed within the Unitary Correlation Operator Method (UCOM), which describes the dominant interaction-induced sh…
Hartree-Fock and Many-Body Perturbation Theory with Correlated Realistic NN-Interactions
R. Roth, P. Papakonstantinou, N. Paar +3
We employ correlated realistic nucleon-nucleon interactions for the description of nuclear ground states throughout the nuclear chart within the Hartree-Fock approximation. The cru…
Collective excitations in the Unitary Correlation Operator Method and relativistic QRPA studies of exotic nuclei
N. Paar, P. Papakonstantinou, H. Hergert +1
The collective excitation phenomena in atomic nuclei are studied in two different formulations of the Random Phase Approximation (RPA): (i) RPA based on correlated realistic nucleo…
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…
