Description
Summary:. The behavior of double helices (DH * formed in the temperature interval N * -SmA * in compounds of non-chiral liquid crystals doped with chiral molecules was investigated. Two different systems presenting left-handed and right-handed chirality were studied. A statistics of the handedness of the DH * revealed a correlation with the mixture chirality, as predicted theoretically in C. Meyer, Yu. A. Nastishin, M. Kleman, Phys. Rev. E 82 , 031704 (2010). By applying a gradually increasing AC electric field, one can observe the shrinking of the cylinder circumscribing the DH * . This shrink is accompanied by a reduction of the DH * 's pitch. This effect was similar to the one produced by the decrease of temperature in the absence of the field. Graphical abstract
