      abstract     = {The liquid crystalline behavior of a two dimensional (2D)
                      model of hard needles bent into a "zigzag shape" is studied.
                      This model, originally designed to study two dimensional
                      chiral segregation, also shows liquid crystalline behavior
                      and has some anomalous features which are contrasted in
                      relation to the following: (i) Most of the microscopical
                      models used to study liquid crystals have a symmetry axis
                      that coincides with a molecular axis; (ii) in
                      three-dimensions, chiral molecules can form cholesteric
                      instead of nematic phases; (iii) the smectic phase is
                      usually found when attractions are present or at least when
                      the molecules have finite volume. Despite the fact that the
                      present 2D model does not have any of these characteristics,
                      numerical evidence is found for the occurrence of nematic
                      and smectic phases. Since these molecules are athermal,
                      infinitely repulsive, and infinitesimally thin, the liquid
                      crystalline characteristics are attributed to excluded
                      volume effects. To determine the mesophases of the model,
                      both nematic and smectic order parameters as well as
                      distribution functions are computed.},
