Free energy fluctuations for bimodal directed polymers in 1+1 dimensions.
By investigating the covariance between the free energy and the entropy, we studied the free energy fluctuations for bimodal directed polymers at finite temperatures. It is proposed that they have a phase transition from the KPZ behavior for p<p(c) to the EW behavior for p>p(c) for the free energy fluctuations at any finite temperature.
