| Abstract: | The linear response in a charge density wave (CDW) type state is investigated in the framework of 1+1-dimensional QED. It is shown that the system is unstable or stable against static, periodic electric perturbations when the Fermi level is placed in an allowed band or a forbidden one, respectively. |
