Deformation energetic effects for cholestric liquid crystals

Abstract

New energetic effects for cholesteric liquid crystals subjected to orientational deformation such as the heat production or absorption at isothermal deformation, the chemical potential changing of multicomponent cholesterics and the temperature variation at adiabatic deformation, the noticeable difference between the isothermal and adiabatic moduli of torsion are predicted. The theory of these effects is developed on the basis of the previously obtained thermodynamic relations for a deformed liquid crystal.
