    • We theoretically analyze the d.c Josephson current between two superconductors connected by a vibrating weak link. Assuming the weak link to be a ``quantum dot" we predict that the critical current is thermally enhanced at low temperatures if the electron-vibron interaction is strong and has an anomalous temperature dependence in a large temperature interval. We estimate that this unusual behavior, which occurs because the current through the weak link is carried by ``polaronic" Andreev states, is measurable in experiments on, e.g., carbon-nanotube based Josepshon junctions.
