[en] We present a Monte Carlo simulation study of helical Yukawa rods as a model for chiral liquid crystal
mesogens.To simulate the cholesteric phase, we introduce a newsimulation method that uses softwalls
and self-determined boundary conditions. We observe that the isotropic-nematic phase transition is
shifted to lower volume fractions with decreasing salt concentration as well as with increasing internal
pitch of the rods. For particular sets of interaction parameters, the sense of the cholesteric pitch inverts,
i.e., depending on concentration, mesogens of a given handedness can produce cholesteric phases of
both chiral senses.
