Two-point free energy distribution function in (1+1) directed polymers
arXiv:1304.6571 · doi:10.1088/1751-8113/46/35/355001
Abstract
In this brief technical communication it is demonstrated how using Bethe ansatz technique the explicit expression for the two-point free energy distribution function in (1+1) directed polymers can be derived in rather simple way. Obtained result is equivalent to the one derived earlier by Prolhac and Spohn.
