  We have demonstrated that Lorentz-violating terms stemming from the fermion
sector of the SME are able to generate geometrical phases on the wave function
of electrons confined in 1-dimensional rings, as well as persistent spin
currents, in the total absence of electromagnetic fields. We have explicitly
evaluated the eigenenergies and eigenspinors of the electrons modified by the
Lorentz-violating terms, using them to calculate the dynamic and the
Aharonov-Anandan phases in the sequel. The total phase presents a pattern very
similar to the Aharonov-Casher phase accumulated by electrons in rings under
the action of the Rashba interaction. Finally, the persistent spin current were
carried out and used to impose upper bounds on the Lorentz-violating
parameters.
