  We analyze the ``ferron" excitations in order-disorder ferroelectrics by a
microscopic pseudo-spin model. We demonstrate that analogous to magnons, the
quanta of spin waves in magnetic materials, ferrons carry both static and
oscillating electric dipole moments, exhibit a Stark effect, and may be
parametrically excited by THz radiation. The anti-crossing gap of the
ferron-photon hybrid depends strongly on propagation direction and an applied
static electric field. We predict ferron diffusion lengths that can reach
centimeters, which implies efficient transport of electric polarization by
temperature gradients. These properties suggest that ferroelectric materials
may be useful for information technology beyond data storage applications.
