Variational neural-network solution of the two-body proton-halo problem with a Coulomb--Whittaker tail
Lucas A. Souza, Tobias Frederico
We present a variational artificial neural-network (VANN) solution of F in a two-body O potential model. The calculation uses a standard interaction from the lite…
Neural-network solution of subtracted three-body Faddeev integral equations near the Efimov limit
Lucas A. Souza
We apply a deep-neural-network (DNN) ansatz to the symmetrized spectator vector of the subtracted three-body Faddeev integral equation for identical bosons near the Efimov limit. T…
Inclusive Breakup Cross Sections in Reactions Induced by the Nuclides He and Li in the Two-Body Cluster Model
L. A. Souza, E. V. Chimanski, B. V. Carlson
Calculations of inclusive particle production are performed to interpret reaction experimental data induced by the two-neutron halo He and the isotopes Li on differ…
Short-range correlation effects on the neutron star cooling
Lucas A. Souza, Rodrigo Negreiros, Mariana Dutra +2
Short range correlations (SRC) have been known to be an important aspect of nuclear theory for some time. Recent works have re-ignited interest on this topic, particularly due to t…
Short-range correlations effects on the deformability of neutron stars
Lucas A. Souza, Mariana Dutra, César H. Lenzi +1
In the present work, we investigate the effects of short-range correlations (SRC) on the dimensionless deformability of the binary neutron system related to the GW170817 event. We…
Four-body eikonal approach to three-body halo nuclei scattering
L. A. Souza, E. V. Chimanski, T. Frederico +2
Halo nuclei projectiles can undergo into a fragmentation process when scattered by a nucleus target. The corresponding core from exotic nuclei is usually observed while the others…
Inclusive Breakup Theory of Three-Body Halos
M. S. Hussein, L. A. Souza, E. Chimanski +2
We present a recently developed theory for the inclusive breakup of three-fragment projectiles within a four-body spectator model \cite{CarPLB2017}, for the treatment of the elasti…
Scaling limit analysis of Borromean halos
L. A. Souza, F. F. Bellotti, T. Frederico +2
The analysis of the core recoil momentum distribution of neutron-rich isotopes of light exotic nuclei is performed within a model of the halo nuclei described by a core and two neu…
Core momentum distribution in two-neutron halo nuclei
Lucas A. Souza, Filipe F Bellotti, Marcelo T. Yamashita +2
The core momentum distribution of a weakly-bound neutron-neutron-core exotic nucleus is computed within a renormalized zero-range three-body model, with interactions in the s-wave…
Superfluidity in Two-Dimensional Imbalanced Fermi Gases
Heron Caldas, A. L. Mota, R. L. S. Farias +1
We study the zero temperature ground state of a two-dimensional atomic Fermi gas with chemical potential and population imbalance in the mean-field approximation. All calculations…
