From the Frenkel-Kontorova model to Josephson junction arrays - the Aubrys transition as a jamming-glass transition -

The Frenkel Kontorova (FK) model is known to exhibit the so called Aubrys transition which is a jamming or frictional transition at zero temperature. Recently we found similar transition at zero and finite temperatures in a super-conducting Josephson junction array (JJA) on a square lattice under external magnetic field. In the present paper we discuss how these problems are related.
