template<typename SpinType = int>
class Ising

#include <Ising.h>

Ising Hamiltonian This defines the Ising Hamiltonian.

It only consists of a single part, namely the interaction.

Template Parameters

• SpinType: the type in which to store the binary magnetization values.

namespace MARQOV

The MARQOV namespace.

This namespace collects all things that are related to MARQOV.

template<class Lattice>
struct Wolff<Ising<int>, Lattice>

#include <Ising.h>

Specialization of the Wolff algorithm for the Ising model.

The principle structure is identical to the general version of the algorithm See wolff.h for details
