Hello,
Is there a simple way to get at the histogram of the distribution of the magnetization in the ground state of (say) the transverse field Ising model? Or failing that, a way to get out the full ground state eigenvector obtained by exact diagonalization?
A related question: Is there a simple way to take the expectation value of an arbitrary function of spin at a single site in Monte Carlo? I guess this comes under "Definition of custom measurements", and that tutorial isn't finished yet.
Thanks,
Austen
