We use the SU(2) slave fermion approach to study a tetrahedral spin 1/2chain, which is a one-dimensional generalization of the two dimensional Kitaevhoneycomb model. Using the mean field theory, coupled with a gauge fixingprocedure to implement the single occupancy constraint, we obtain the phasediagram of the model. We then show that it matches the exact results obtainedearlier using the Majorana fermion representation. We also compute thespin-spin correlation in the gapless phase and show that it is a spin liquid.Finally, we map the one-dimensional model in terms of the slave fermions to themodel of 1D p-wave superconducting model with complex parameters and show thatthe parameters of our model fall in the topological trivial regime and hencedoes not have edge Majorana modes.
