Hamiltonian system의 경우 Hamiltonian으로 부터 free energy를 계산할 수 있고 그로부터 equilibrium에서의 thermodynamics quantities를 알 수 있다.
■ Glauber dynamics
Single spin flip dynamics
Transition rate가 다음과 같이 주어진다.
,
when the energy change becomes 0, the transition rate becomes 1/2. Thus the factor which is multiplied controls the flip probability for zero energy difference.
■ Design of the transition rate
zero temperature Glauber dynamics can be mapping to the voter model.
