Optimized binning for response function reconstruction via Chebyshev expansions
Immo C. Reis, Joanna E. Sobczyk, Sonia Bacca
We propose an optimized histogram binning strategy to reconstruct nuclear response functions via the Chebyshev expansion bound-state method. Our approach employs a stochastic regul…
16O electroweak response functions from first principles
Bijaya Acharya, Joanna E. Sobczyk, Sonia Bacca +2
We present calculations of various electroweak response functions for the 16O nucleus obtained using coupled-cluster theory in conjunction with the Lorentz integral transform metho…
Neutrino and antineutrino charged-current multi-nucleon cross sections revisited
J. E. Sobczyk, J. Nieves
In this work we improve on several aspects of the computation of the (anti-)neutrino charged-current multi-nucleon cross section carried out in Phys.Rev.C 83 (2011) 045501 and Phys…
Spin response of neutron matter in ab initio approach
J. E. Sobczyk, W. Jiang, A. Roggero
We propose a general method embedded in the ab initio nuclear framework to reconstruct linear response functions and calculate sum rules. Within our approach, based on the Gaussian…
