Universal relation between dipole polarizability of finite nuclei and neutron-star compactness
P. S. Koliogiannis, T. Ghosh, E. Yuksel +1
The nuclear equation of state, which determines the structure and properties of neutron stars, remains subject to substantial theoretical uncertainties, leading to model dependence…
Dipole Polarizability of Finite Nuclei as a Probe of Neutron Stars
P. S. Koliogiannis, E. Yuksel, T. Ghosh +1
Nuclear ground state and collective excitation properties provide a means to probe the nuclear matter equation of state and establish connections between observables in finite nucl…
Subtracted second Tamm-Dancoff approximation in the relativistic point-coupling model
Deni Vale, Nils Paar
Theoretical description of collective nuclear excitations and astrophysically relevant processes require methods going beyond the Random Phase Approximation (RPA) or Tamm-Dancoff A…
Conflation of Ensemble-Learned Nuclear Mass Models for Enhanced Precision
Srikrishna Agrawal, N. Chandnani, T. Ghosh +3
Ensemble learning algorithms, the gradient boosting and bagging regressors, are employed to correct the residuals of nuclear mass excess for a diverse set of six nuclear mass model…
Hot pygmy dipole strength in nickel isotopes
Amandeep Kaur, Esra Yüksel, Nils Paar
At finite temperatures, nuclear excitations are significantly modified, most notably through the emergence of additional low-energy dipole strength, which can critically impact ast…
Electric and magnetic -ray strength functions at finite-temperature
Amandeep Kaur, Esra Yüksel, Nils Paar
The -ray strength function (SF) is essential for understanding the electromagnetic response in atomic nuclei and modeling astrophysical neutron capture rates. We introduced…
