Query: Ring statistics in 2D-silica: effective temperatures in equilibrium   The thermodynamic properties of subsystems in strong interaction with the
neighborhood can largely differ from the standard behavior. Here we study the
thermodynamic properties of rings and triplets in equilibrated disordered
2D-silica. Their statistics follows a Boltzmann behavior, albeit with a
strongly reduced temperature. This effective temperature strongly depends on
the length scale of the chosen subsystem. From a systematic analysis of the 1D
Ising model and an analytically solvable model we suggest that these
observations reflect the presence of strong local positive energy correlations.
