A study of open shell nuclei using chiral two-body interactions
Giovanni Puddu
We apply the Hybrid-Multi-Determinant method using the recent chiral two-body interactions of Entem-Machleidt-Nosyk (EMN) without renormalization to few nuclei up to A=48. Mostly w…
Effect of residual many-body forces due to the evolution in the in-medium similarity renormalization group method
G. Puddu
In the past few years in-medium similarity renormalization group methods have been introduced and developed. In these methods the Hamiltonian is evolved using a unitary transformat…
Many-body calculations with Deuteron based single-particle bases and their associated natural orbits
Giovanni Puddu
We use the recently introduced single-particle states obtained from localized Deuteron wave-functions as a basis for nuclear many-body calculations. We show that energies can be su…
A new single-particle basis for nuclear many-body calculations
Giovanni Puddu
Predominantly, harmonic oscillator single-particle wave functions are the choice as a basis in ab-initio nuclear many-body calculations. These wave-functions, although very conveni…
Description of nuclei around N=20 starting from the Argonne V18 interaction
Giovanni Puddu
Using the Argonne V18 interaction, renormalized with the Lee-Suzuki method, we study nuclei around the island of inversion. We include 5 major oscillator shells, in a no-cor…
Extention of the Time-Dependent Multi-Determinant approach to propagators
Giovanni Puddu
We extend the recently proposed Time-Dependent Multi-Determinant approach (ref.[1]) to the description of fermionic propagators. The method hinges on equations of motions obtained…
