The directed polymer problem in general dimension

Physica A: Statistical Mechanics and its Applications, 1996, vol. 234, issue 1, 523-528

Abstract: A real space RG treatment of the directed polymer problem is presented. In the zero temperature regime (strong coupling) no upper critical dimension is found. The method that is based on the exact results in 1 + 1 dimensions yields in 2 + 1 and 3 + 1 dimensions excellent agreement with published numerical results.
