Abstract
We analyze the out-of-equilibrium behavior of an Ising spin chain with an asymmetric kinetic constraint after a quench to a low temperature . In the limit , we provide an exact solution of the resulting coarsening process. The equilibration time exhibits a “glassy” divergence (popular as an alternative to the Vogel-Fulcher law), while the average domain length grows with a temperature-dependent exponent, . We show that the equilibration time also sets the time scale for the linear response of the system at low temperatures.
