Probability distribution of the free energy of a directed polymer in a random medium
We calculate exactly the first cumulants of the free energy of a directed polymer in a random medium for the geometry of a cylinder. By using the fact that the nth moment <Z(n)> of the partition function is given by the ground-state energy of a quantum problem of n interacting particles on a r...
