| contents | Using a field theory equivalent to a lattice version of the Poland-Scheraga (PS) model, the phase diagram for a long DNA molecule is derived in closed form. A one-loop renormalization group calculation for the generalized PS model with excluded volume interactions shows that there are two stable fixed points. At both fixed points, the excluded volume effect plays a role. At the fixed point reached when the original excluded volume effect is weak, the phase transition is continuous. At the other fixed point, the phase transition is first order. |
