2. Example

2.1. Two-dimensional 16 * 16 square lattice Ising model

1. Construct the microcanonical entropy.

Note

The microcanonical entropy corresponds to the density of states with the relation, S = ln W(E).

% cd 2dising
% ../bin/cluster
% ../bin/wang-landau

2. Plot the microcanonical entropy.
