Vortex and gap generation in gauge models of graphene
O. Oliveira, C. E. Cordeiro, A. Delfino +2
Effective quantum field theoretical continuum models for graphene are investigated. The models include a complex scalar field and a vector gauge field. Different gauge theories are…
Dynamical gap generation in graphene nanoribbons: An effective relativistic field theoretical model
A. J. Chaves, G. D. Lima, W. de Paula +4
We show that the assumption of a nontrivial zero band gap for a graphene sheet within an effective relativistic field theoretical model description of interacting Dirac electrons o…
Elastic electron-deuteron scattering and two-body current operators in the Light-Front Hamiltonian Dynamics
Tobias Frederico, J. Adnei Marinho, Emanuele Pace +1
The electromagnetic properties of the deuteron are investigated within a Light-Front Hamiltonian Dynamics framework, with a current operator that contains both one-body and two-bod…
Projecting the Bethe-Salpeter Equation onto the Light-Front and back: A Short Review
Tobias Frederico, Giovanni Salme`
The technique of projecting the four-dimensional two-body Bethe-Salpeter equation onto the three-dimensional Light-Front hypersurface, combined with the quasi-potential approach, i…
Nucleon-nucleon scattering within a multiple subtractive renormalization approach
V. S. Timoteo, T. Frederico, A. Delfino +1
A methodology to renormalize the nucleon-nucleon interaction, using a recursive multiple subtraction approach to construct the kernel of the scattering equation, is presented. We s…
Double resonances in Borromean heteronuclear triatomic systems
F. Bringas, M. T. Yamashita, T. Frederico +1
We investigate the occurrence of Borromean three-body continuum s-wave resonances, in an system for large negative two-body scattering lengths. The energy and width are deter…
