New Solutions to the Yang--Baxter Equation from Two--Dimensional   Representations of $U_q(sl(2))$ at Roots of Unit
  We present particularly simple new solutions to the Yang--Baxter equation arising from two--dimensional cyclic representations of quantum $SU(2)$. They are readily interpreted as scattering matrices of relativistic objects, and the quantum group becomes a dynamical symmetry.
