Charge and Spin Currents in a Lower-Dimensional Supersymmetric Model in Presence of Vortices
Cristine N. Ferreira, J. P. S. Alves e Silva, J. A. Helayel Neto +1
We investigate charge and spin currents that may appear in some materials, considering the possible couplings and the symmetries of a field-theoretical model presented here. We ins…
Torsion Effects and LLG Equation
Cristine N. Ferreira, Cresus F. L. Godinho, J. A. Helayël Neto
Based on the non-relativistic regime of the Dirac equation coupled to a torsion pseudo-vector, we study the dynamics of magnetization and how it is affected by the presence of tors…
Thinking anew causality problems for the radiation reaction force
Reinaldo de Melo e Souza, J. A. Helayël Neto
In this work, we analyze a Lagrangian formalism recently proposed to approach the issue of the Abraham-Lorentz force. Instead of involving only position and velocity, as usual in C…
Vortex Formation in a , N=2, D=3 Supersymmetric Gauge Model
C. N. Ferreira, J. A. Helayël Neto, A. A. V. Paredes
In this work, we study a model that results from a dimensional reduction of the N=1-D=4 supersymmetric version of the Cremer-Scherk-Kalb-Ramond model…
