Exact sampling from non-attractive distributions using summary states

Thermodynamic plots

Exact sampling from the Boltzmann distribution of a spin system allows us to calculate thermodynamic quantities — for example, the mean energy per spin,
the mean magnetization fraction,
and the heat capacity,
Angle brackets denote ensemble averages.

Using exact sampling of a 632=3969 spin Ising system on a triangular lattice, we computed these quantities as a function of temperature. Plots are in EPS format.
