title: Stress-induced dislocation roughening: a phase transition in one dimension at finite temperature.
abstract: We present an example of a generically forbidden phase transition in 1D at finite temperature-stress induced and thermally assisted roughening of a superclimbing dislocation in a Peierls potential. We also argue that such roughening is behind the strong suppression of the superflow through solid (4)He in a narrow temperature range recently observed by Ray and Hallock [Phys. Rev. Lett. 105, 145301 (2010)].
