Abstract
Some equilibrium configurations of the cholesteric unwinding transition problem are numerically computed using the Landau-de Gennes expression of the liquid crystal free energy density. The classical TIC and modulated TIC configurations are numerically obtained and the cholesteric finger structure is found to be in good agreement with the previous theoretical guesses. Moreover, we report the existence of new solutions, specifically associated with the local n → -n symmetry, and which seem to be experimentally observed.
