A Liquid crystals: dielectric torque and electric torque

  1. Jan 1, 2018 #1
    Dear Members,

    I was reading a tutorial on ferroelectricity of liquid crystals, underneath is the excrept:

    "For ferroelectric materials, in addition to the dielectric torque, the electric torque will have a term due to the linear coupling between the spontaneous polarization"

    Could someone please help me understand the differnce between the dielectric torque and the electric torque. How does the electric torque couple with spontaneous ?

    Thank you
