Two-body double pole and three-body bound states: physical and unphysical quark masses
V. S. Timoteo, U. van Kolck
We solve the Faddeev bound-state equations for three particles with simple two-body nonlocal, separable potentials that yield a scattering length twice as large as a positive effec…
Nonlinear Klein-Gordon equation and the Bose-Einstein condensation
E. Megias, M. J. Teixeira, V. S. Timóteo +1
The interest in the Klein-Gordon equation with different potentials has increased in recent years due to its possible applications in Cosmology, Hadron Physics and High-Energy Phys…
On-shell transition of SRG and nuclear systems
E. Ruiz Arriola, S. Szpigel, V. S. Timoteo
We make variational estimates for the binding energies of , showing their running with the Similarity Renormalization Group (SRG) cutoff towards th…
Pions and Contacts at N4LO: Some details on the chiral nuclear force
E. F. Batista, S. Szpigel., V. S. Timoteo
In this work we have performed a detailed study of chiral nuclear forces at N4LO approximation applied to selected channels of the neutron-proton () scattering. The idea is to…
BCS Pairing Gap in the Infrared Limit of the Similarity Renormalization Group
Sergio Szpigel, Varese Salvador Timoteo, Enrique Ruiz Arriola
Effective interactions have been used to compute the pairing gap for nuclear and neutron matter in several schemes. In this work we analyze the impact of phase-shift equivalent int…
Phase transition in the SRG flow of nuclear interactions
Varese S. Timoteo, Enrique R. Arriola, S. Szpigel
We use a chiral interaction at N3LO in the 1S0 channel of the nucleon- nucleon interaction in order to investigate the on-shell transition along the similarity renormalization grou…
