DESCRIPTION:Title: The phase diagram of the polymer model.\n\nAbstract: \n
 \nIn dimension 1\, the directed polymer model is in the celebrated KPZ uni
 versality class\, and for all positive temperatures\, a typical polymer pa
 th shows non-Brownian KPZ scaling behavior. In dimensions 3 or larger\, it
  is a classical fact that the polymer has two phases: Brownian behavior at
  high temperature\, and non-Brownian behavior at low temperature. We consi
 der the response of the polymer to an external field or tilt\, and show th
 at at fixed temperature\, the polymer has Brownian behavior for some field
 s and non-Brownian behavior for others. In other words\, the external fiel
 d can *induce* the phase transition in the directed polymer model.\n\n \n
