A sine-Gordon type renormalization group study reveals the existence of a Splay glass phase and yields an analytic form for the transition temperature into the glass phase. As an independent test, the I V characteristics are determined via a Molecular Dynamics code. The glass transition temperature supports the RG results convincingl...
