Joint ground states of two directed polymers in a random medium are investigated. Using exact min-cost flow optimization, the true two-line ground-state is compared with the single line ground state plus its first excited state with "worst-possible" initial conditions, where the two lines start next to each other. It is found that these two-line configurations are (for almost all disorder configurations) distinct implying that the true two-line ground-state is nonseparable, which means that the…

It follows that the susceptibility of domain walls also has a logarithmic dependence on the system size, and is illustrated by mapping the problem into the Kardar-Parisi-Zhang roughening process.
Anomalous fluctuations of directed polymers in random media.

Physical review. B, Condensed matter
• 1994
It is argued that the power-law distribution of large thermally active excitation is a consequence of the continuous statistical tilt'' symmetry of the directed polymer, the breaking of which gives rise to the large active excitations in a manner analogous to the appearance of Goldstone modes in pure systems with a broken continuous symmetry.

Numerical simulations indicate delocalization by randomness in cases where there is no analogous depinning by thermal fluctuations, e.g. , as in an interface bound to a strip of weak bonds in the bulk, or for two attracting interfaces.

Directed polymers subject to quenched external impurities (as in a polyelectrolyte in a gel matrix) are examined analytically, and numerically to suggest a superuniversal exponent of $\ensuremath{\nu}=\frac{2}{3}$.
