We have used the Ising model to study the behavior in ferromagnets, when undergoing
|
|
a phase transition near a critical temperature. We generated samples using the
|
|
Markov chain Monte Carlo method, while utilizing methods of parallelization.
|
|
Finding the burn-in time to be approx. 3000 Monte Carlo cycles. For temperature
|
|
$T = 1.0 J / k_{B}$ we found a propability distrobution with an expected mean
|
|
value of $\mu \approx -1.9969$ and variation $\sigma^{2} = 0.0001$. Whereas the
|
|
pdf close to the critical temperature is $\mu \approx -1.2370$ and variation
|
|
$\sigma^{2} = 0.0203$. We estimated the expected energy and magnetization per spin,
|
|
in addition to the heat capacity and susceptibility. Using the values from
|
|
finite sized lattices, we approximated the critical temperature of an infinite
|
|
sized lattice. Using linear regression, we numerically estimated $T_{c}$ $T_{C}(L = \infty) \approx 2.2695$
|
|
which is close to the analytical solution $T_{C}(L = \infty) \approx 2.269 J/k_{B}$
