• Relativistic particles with torsion in three-dimensional non-vacuum spacetimes 

      Herrera, Jónatan; Rosa, M. de la; Rubio, Rafael (American Institute of Physics, 2021)
      In this paper, we analyze trajectories of spacelike curves that are critical points of a Lagrangian depending on its total torsion. We focus on two important families of spacetimes, generalized Robertson–Walker and standard ...
