Progressive quenching --- Ising chain models

Understand

Of the Ising spin chain with the nearest neighbor or up to the second nearest neighbor interactions, we fixed progressively either a single spin or a pair of neighboring spins at the value they took.

• Before the subsequent fixation, the unquenched part of the system is equilibrated.
• We found that, in all four combinations of the cases, the ensemble of quenched spin configurations is the equilibrium ensemble.
